2 Important Reasons Why Your HVAC Technician Measures Draft

October 26th, 2017

One of the most important aspects of your furnace is how it drafts. When air drafts properly from your gas furnace or gas water heater, spent oxygen and carbon monoxide go up a chimney or chimney pipe where it is dispersed outside your home. As most are aware, too much carbon monoxide in an enclosed area can have tragic results. The importance of proper drafting of a furnace can not be overstated for both operating efficiency and monitoring safe conditions.

How do we know, however, that a gas furnace has the appropriate draft pressure and draft intensity to operate efficiently and safely? It can be done using a furnace diagnostic tool called a draft gauge. A modern draft gauge is a digital device that helps a technician conduct a draft test, measuring aspects like draft pressure, draft intensity, backdrafting, and the percentage of oxygen and carbon monoxide. A draft test is a critical part of any furnace maintenance or tune-up.

How Does a Draft Gauge Work?

A differential pressure draft gauge measures the difference in the pressures of the air flowing inside a chimney or ductwork and that of the air on the outside. A draft gauge will not tell our technician what the specific cause of the draft issue is, only that there is some issue causing a draft pressure problem. The technician will then rely on his training, experience, and knowledge to discover the source of the draft problem.

Common Causes of Poor Drafting in a Furnace

A variety of causes can create poor drafting for a furnace. These can include extremes in indoor and outdoor temperatures, blockage of the vent pipe, loss of a vent or chimney cap, high winds, and others. This can cause poor ventilation or backdrafting, causing harmful gasses to spill back into the home.

While a slow or diminished draft can cause safety issues, excessive drafts can create inefficiencies in your furnace. If too much air is delivered to the burner fan, it can result in air leaking into the heating plant. This reduces the amount of CO2 and creates an increased stack temperature. This, in turn, results in poor efficiency of the furnace.

Why a Draft Gauge is often Used with a Combustion Analyzer

A draft gauge is often used with combustion analyzer so a technician can better determine the extent of the poor drafting and see its effect on the air in a room. Depending on the readings of the combustion analyzer, it can direct the technician to check on potential issues with the heat exchanger. It can also be an indication there may be a gas pressure issue or a combustion air problem. A high carbon monoxide parts-per-million reading on a combustion analyzer could also mean that a furnace is recirculating flue products and re-burning them in the heat exchanger. We’ve created a brief video on how a draft gauge and combustion analyzer work together as terrific furnace diagnostic tools in helping direct us to the heart of many furnace issues promptly. This saves us time and you money.

Monitoring Safe Conditions

Many Chicago area homeowners will schedule a fall furnace check-up or tune-up to head off potential maintenance issues in the winter and to ensure their furnace is operating at peak efficiency. Another important aspect of an annual furnace check-up, however, is that it monitors the safety of you and your family. It determines the quality of the draft of your furnace, making sure it is operating without putting harmful gasses back into your home.

If you have yet to have a furnace maintenance check this fall, we invite you to contact the well-trained, well-equipped team at Althoff Industries.

The #1 Way to Improve Air Flow in Your Home

October 17th, 2017

Many homeowners don’t fully appreciate the importance of airflow when it comes to the performance of their HVAC system and ultimately, the comfort of each room in your home. The fact is, if you have one room or many rooms that are less comfortable than others, it is quite possible it is an issue with airflow. Free airflow is disturbed by two basic forces friction and turbulence. What are some of the causes of poor or restrictive airflow in a home and how can it be improved? What is the #1 way to improve airflow in your home?

To find out the #1 way to improve airflow, we will first discuss 5 causes of poor airflow. At Althoff, our goal is always to get to the root of the problem first then provide solutions to improve comfort, function and performance of your equipment.

5 Causes of Poor Airflow

5. Duct Work That is Improperly Installed or Blocked

This happens more frequently than you may think. Improperly installed ductwork may not be sized properly or may even not be connected correctly. We have seen ductwork runs that seem to simply and mysteriously end! More common is ductwork that becomes blocked through the years by layers of dirt and dust or even foreign objects like clothing and toys. These improperly installed or blocked ducts create frictions that restrict proper airflow and will negatively affect the comfort of a room.

4. Lengthy Duct Runs and Those That Contain Too Many Turns

Some installers just expect too much from their HVAC, installing lengthy duct runs or duct runs that have too many turns. These turns create turbulence that doesn’t allow them to efficiently reach their desired destinations.

3. Too Few or too Small Return Air Vents

An efficiently installed and operating HVAC system with good airflow will both push air into a room and pull it out at the same rate. If too much air is being pushed into a room, it becomes slightly pressurized and uncomfortable. A frequent problem with rooms with poor air flow is that of having too few or too small return air vents.

2. Ducts That “Leak” Air

Over the course of the life of a structure, duct work can easily get holes or cracks from a combination of age, settling, and alterations to the structure. Duct work is often inadvertently punctured through nails. Like holes in a water hose, this leaking air can make the duct work and thus the furnace, much less effective in delivering treated air and in returning fresh air. It is estimated that nine out of ten homes have duct work that is leaking on some level. Depending on the number, size, and location of these holes, airflow can be dramatically negatively affected.

1. Dirty Air Filter

While the above issues negatively affecting air flow in your home may take the assistance of a professional to properly correct, the simple, most effective way to improve air flow is to keep your air filter clean by performing regular air filter maintenance. Air filters are inexpensive and easy to change on your own. Ideally, they should be changed bi-monthly. If you have gone to a more restrictive air filter to get cleaner air in your home, it may be too restrictive for your HVAC system. If you have found some rooms becoming more uncomfortable, you may want to select a less restrictive filter. We’ve put together a brief video that helps explain why this is such an effective and simple idea to improve airflow in your home.

How Do You Define HVAC Contractor? This Definition Is Pretty Hard To Beat

October 11th, 2017

The Althoff Definition of a Quality HVAC Technician

You probably have seen, read or heard advertisements from HVAC contractor companies in the greater Chicago area that talk about their “quality”. They’ll boast of the quality of their equipment, the quality of their service, and even the quality of the technicians they hire. Quality has become a word that is so overused in the service industry that it often loses its meaning. When it comes to HVAC, through the years, we’ve discovered there is a big difference in what they refer to as “quality”, and what our high standards are at Althoff Industries. Our definition of a quality HVAC technician reaches beyond most HVAC companies in the Crystal Lake IL area.

Treating Problems at the Core Cause

At Althoff Industries, our technicians are trained to find the core cause of a problem. They are not on a mission to “find” problems that may or may not exist. They are not there to sell you something. From the moment an Althoff team member answers your call to the moment we arrive at your home, we are there to resolve your HVAC problem at its root cause, keep your family safe, and restore comfort to your home. They are there to offer logical options and let you make the final choice. They are often asked, “What would you do?”. In fairness, every family has different budget restraints. Our technicians are there to provide you HVAC options that are safe. The choice is ultimately yours, the way it should be. Don’t let an HVAC contractor sell you on a solution that may be their own best interest.

Why Finding the Core Cause is Important

Our technicians are trained to find the core cause of a problem because without that knowledge, technicians often just treat the symptoms. Our Althoff technicians are there to determine WHY a part failed and WHY your HVAC system isn’t performing properly. When an HVAC contractor tells you you need a new part, they should be able to tell you WHY the part failed. If they say “normal wear and tear” and your furnace is less than ten years old, it should raise red flags. If they can’t offer a logical reason for the part failure and you simply replace it, you may just soon experience the same failure sometime in the near future.

Technicians, Training, and Tools

Want to hear something you may already know? Some HVAC people are more interested in selling you something than helping resolve your problem. Shocker right? At Althoff, we have a client-centered focus that compels us to determine your problem at its root cause and then offer you the best options to resolve it. No hidden agendas. We do this through good people who embrace our mission. They have families and understand the challenges of dealing with unexpected issues like HVAC maintenance problems. Next, we provide our HVAC technicians with superior training and exposure to the latest available techniques and technology. That technology includes innovative digital tools that can better determine exactly what is going on with your HVAC system. These tools accurately determine the underlying cause of your problem. We are not just guessing. We use precise instrumentation to verify how your system is performing. We know you expect more than an educated guess from a “quality” HVAC company. At Althoff Industries, we deliver.

Discover a Higher Definition of Quality at Althoff Industries

If you have been frustrated with an HVAC technician who “guesses” at your problem, or simply replaces a failed part without being able to tell you why it failed, contact Althoff Industries. Our service technicians are trained and have the latest tools to diagnose your HVAC problem efficiently and effectively. Best of all, they offer honest solutions that can best fit your family’s needs. Expect more and get more.

Althoff Home What Makes HVAC contractors Different

6 Items to Check Before Calling for Furnace Service

October 4th, 2017

At Althoff Industries, we make our living helping people keep their families safe and cozy with efficient operating HVAC systems. We have built our business and reputation by providing superior service that prevents and resolves issues, not creates them. It’s why many of our customers trust us for their annual furnace tune-ups in the fall. They know our extensive furnace tune-ups provide peace of mind. But furnace tune-up or not, problems can still occur.

Losing heat can be frustrating in winter weather but that frustration can be compounded when realizing, after the fact, that a problem was simple to resolve on your own. If you live in the Crystal Lake area of Northwest Chicago, before you call Althoff Industries or any HVAC company, here are six items you should check.

Check the thermostat setting. Many families will reset thermostats when they leave for work or retire for the evening. Depending on your thermostat, it is possible a temperature setting gets accidentally way low or even takes the thermostat off of the “heat” setting. Before calling for furnace service, take a close look at your thermostat to make sure it is set properly.
Make sure your furnace has power. Even if you use natural gas, your furnace is reliant on electricity. If that electricity is interrupted, you won’t have heat. It may just be that a circuit breaker got shut off for a variety of reasons. Check the circuit breaker for your furnace and reset it if it is in the “off” position. If it immediately pops off again, call a technician.
Check your furnace filter. If rooms are not being heated properly, it could be because fresh air is not getting into the furnace. A common cause is a clogged or dirty air filter that is restricting air flow. Check your furnace’s air filter. You should be able to see through it when held up to a light. A common symptom of restricted air flow is when a furnace “short-cycles”, going on and off far too frequently to be efficient or to provide adequate heating.
Check the pilot light. Gas furnaces have a small pilot light that should be constantly lit to provide an ignition source for the furnace. This pilot light is usually covered by a small door or metal plate near the base of the furnace, near the base of the base of the heating element. If this pilot light is out, you can try to relight it. This can be done by following the instructions on the on/off/pilot control on the furnace and using an extended barbecue grill type lighter or fireplace length match. Of course, if you have any hesitation about relighting your furnace, call a professional technician.
Take note if your gas service has been interrupted. If your gas supply has been interrupted for any reason, the pilot light will need to be reignited. See tip number 4 above.
Your blower motor may not be functioning. In some cases, furnaces may be producing heat, but that heat is not being dissipated through your home because the blower motor is not working properly. Stand by your furnace and when you hear it ignite, you should shortly hear the start of the electric blower motor. You should feel heat blowing from your vents. If you hear the furnace ignite but don’t hear the blower motor start or feel hot air from a vent, it is likely your blower motor. If you are an exceptional do-it-yourselfer, you may be able to replace the blower yourself. We, however, would suggest calling a professional.

A Few Final Tips Before Calling for Furnace Service in Crystal Lake

Winters can be tough in Crystal Lake and Chicagoland area but before you pay for a service call, take the above steps. You may be able to resolve the issue with a few simple checks. If the above steps are unsuccessful, write down the furnace brand name and model number along with the approximate age of your furnace and relay that to your service company. Let them know the steps you took and your results. This can expedite the service call, potentially saving you money.

If you experience a heating problem and need professional help, we invite you to call us at Althoff Industries. We have over 50 years of experience serving Northwest Chicago and have a highly trained staff of technicians with the latest technology to make sure your repair is done promptly and safely. When it comes to the comfort and safety of your family, trust the experts at Althoff Industries.

8 Common Questions About Annual Furnace Tune Ups

September 28th, 2017

This is the time of year many families schedule their annual furnace tune up. We can’t assume, however, that everyone knows what is involved in a furnace tune up or why it is important. That’s why we’ve compiled a list of eight questions and answers about an annual furnace tune up.

Furnace Tune-Up FAQ’s

What is an annual furnace tune up? An annual tune up is a yearly inspection and cleaning of your furnace to look for potential problems and ensure the heating system is operating efficiently and safely.
When should I schedule an annual furnace tune up? An annual furnace tune up can be done any time, but most families schedule them in the fall, typically around September and October. Scheduling before cold weather hits, when HVAC techs aren’t as busy, makes it easier to get an appointment time that’s convenient for you.
What is involved in a furnace tune up? This depends somewhat on the company that performs the furnace tune up. At minimum, a tune up typically consists of changing the filter, cleaning the furnace, checking electrical connections and voltage, lubricating moving parts, checking burners and ignition, inspection of the condensate drain, chimney, and flue, checking thermostat performance, visually inspecting the heat exchanger, checking and tightening all electrical connections and testing for carbon monoxide. Althoff’s complete furnace tune up also includes a combustion analysis on both the water heater and furnace to ensure they’re working safely, as well as a measure of the draft pressure on the water heater. We also measure ductwork system static pressure to check for leaks, blockages and other inefficiencies in the system. Not every HVAC company does a combustion analysis, draft check and static pressure test, but we include them because they’re the best way to ensure the safe operation of your gas furnace.
Why is a furnace tune up important? A furnace tune up is important not only for the safety of your family but to also make sure your furnace will perform as intended throughout the cold weather months. It can also help your furnace run more efficiently.
Can I perform a furnace tune up on my own? While there may be some elements of a tune up that the average homeowner could handle, like changing the furnace filter, it’s unsafe to perform a complete furnace tune up without the proper equipment and training.
What should I expect to pay for a furnace tune up? You may see furnace tune up coupons advertising $39 or $49 specials, but be cautious. Many time these coupon specials are nothing more than a way for an HVAC company to get into your home so they can recommend more extensive (and costly) repairs or services. Make sure you select an experienced company with a solid reputation. In the Chicago area, a thorough furnace tune up from a reputable HVAC service typically costs anywhere from $80-$140, depending on what’s included and if there are any special offers.
Is a an annual furnace tune up worth it? A furnace tune up provides several valuable results:
- Save on heating energy costs. A regularly-maintained furnace will operate more efficiently, using less energy and saving you money on your heating bills.
- Keep you and your family safer. A gas furnace that isn’t operating properly can can give off lethal levels of carbon monoxide and even pose a fire hazard. An annual tune up can find leaks and other potential problems so they can be addressed.
- Prevent inconvenient breakdowns. No one wants to have to call for emergency HVAC service in the middle of a cold winter night. A fall furnace tune up can detect developing issues so they can be resolved before they become serious.
- Extend the life of your furnace. Dirt and deterioration put added stress on your heating system. A furnace that’s clean and in good working order will last longer and have fewer costly breakdowns.

Sept 25 is National Tune Up Day: Is Your Furnace Ready for Winter?

September 14th, 2017

Now that school is back in session and we settle into our Fall routines, it is time to think about the inevitable winter ahead. In fact, September 25 is National Tune Up Day for furnaces across the country. It is particularly important here in the greater Chicago area where our winters can be brutal. What can you do to be a part of National Tune Up Day? First, you can schedule a furnace tune up. The second thing you can do is to use #NationalTuneUpDay on social media to spread the word. This is important because a furnace tune up is not only a matter of ensuring a furnace is operating efficiently, but that it is operating safely as well.

Why Preventive Furnace Maintenance?

A thorough furnace tune up ensures your heating system is clean, operating efficiently and also checks that any impending part failures are addressed. A skilled technician will have the appropriate tools to test gasses to make sure they are safe and that your furnace is vented properly. Notice we said “thorough” furnace tune-up. Many of the $39 and $49 furnace tune-up coupon specials you’ll see this time of year are no more than a promotional vehicle that may just be used to “find” additional problems. This is why it is important you select an experienced company with the proper equipment and training, a superior reputation and a customer-centric approach.

How Often Should You Schedule a Furnace Tune-Up?

If the tune up is thorough, once a year may be sufficient. We recommend you get a furnace tune up in the Fall as we head into the cold weather season. This assures that your furnace is ready for the hard work that it will be performing in the coming winter months, keeping you warm without interruption. That’s why we feel September 25th is an optimal time to remind our customers, and potential customers, to schedule a tune up.

What Should Be Included in Furnace Preventive Maintenance?

A furnace tune should includes this extensive list:

1. Remove dust and dirt from the unit and vents

2. Check and change HVAC air filter.

3. Ensure fresh air intake grills are not blocked.

4. Check blower wheel and motor for efficient and quiet operation.

5. Secure wiring, check all wiring for any damage or wear.

6. Examine all parts for any corrosion or cause of corrosion.

7. Determine that drains and traps are in good condition.

8. Establish that fuel-jets are working efficiently.

9. Analyze combustion gasses and compare this analysis to what is recommended for your furnace.

An HVAC technician goal while performing this checklist should be to ensure you, the homeowner, that you have a clean, safe, and efficient heating system that will keep your family comfortable throughout the winter months.

Will a Tune-Up Prevent Future Problems?

While a furnace tune up cannot guarantee you won’t have problems in the coming months, you will be far better prepared to prevent problems. In many instances, problems may be age-related, meaning the older your heating system, the more issues you may face. That being said, the older your furnace, the more important a furnace tune up can be. Even on newer systems, however, a furnace tune up can maximize its lifespan.

5 Simple Solutions to Common Residential Plumbing Problems

September 6th, 2017

There are some common residential plumbing problems that usually most people can resolve on their own. And there are a host of others more serious plumbing issues that are best performed by calling a professional like Althoff Industries. Knowing the difference can save you lots of frustration and potentially some serious repairs. Here are 5 simple solutions to some common residential plumbing problems you can likely handle on your own.

Plumbing Problem, Plumbing Solution

1. Leaking Faucet – As advanced as technology is in some areas of life, one constant has been the common residential plumbing problem of a leaky faucet. Faucet leaks are most often caused by a worn washer which can be easily replaced. In a single handle faucet, you know where the culprit is. If you have a two handle faucet, you can determine which is leaking by simply seeing if the water is hot or cold. If you can’t tell, you might as well just replace the washers in both as it is a simple fix.

a. Turn off the water supply to the faucet you are working on. It will be located under the sink.

b. If there is a decorative cap to the handle it will need to be removed. Unscrew the handle, usually with a Phillips head screwdriver.

c. Remove the valve nut or cover that is retaining the valve, and lift the valve out, exposing a washer underneath.

d. You may be best served by taking both the valve and the washer to a hardware store to ensure you get the proper replacement.

e. After replacing the washer, just reassemble your handle in reverse order.

2. Running or Leaking Toilet

Leaking or running toilets are other very common plumbing problems. First, turn off the water supply to the toilet and remove the tank lid. You may simply have a chain attached to the rubber flapper that is too long or short. If it is too short, it’s not allowing the flapper to close. If it’s too long, it may just be getting in the way of the flapper. If your running toilet is due to the float not rising high enough to stop the water from flowing into the tank, it can often be resolved by just bending the rod downward, Toilet tank repair parts and kits are found in any hardware or home improvement store and are inexpensive. A less common problem could be a leak in the big washer that is between the tank and the seat. That is a bigger job and unless you want to do some heavy lifting you may be better served calling in a pro.

3. Jammed Garbage Disposal

If a garbage disposal is jammed with something like a soda can pop top and had stopped working, you may be able to fix it yourself. That is if you have the right tool. There may be an Allen style wrench attached to the motor unit of the disposal. Make sure the power is off then you can insert the wrench into the bottom of the unit and manually turn the blades of the disposal. Once the item is freed, you should be able to carefully remove the item. Once the item is removed, restore power, turn it on, and it should operate normally. If not, give Althoff Industries a call.

4. Clogged Drains – You may be able to clear a clogged drain through a choice of chemical free solutions. You can get a small, inexpensive metal wire “snake” to slid down your drain to remove the obstruction. You could also try to remove the plug using a plunger. Another all-natural solution would be to pour some baking soda down the drain and add some vinegar. Often, the foaming reaction between the baking soda and vinegar can serve to remove a blockage.

5. Frozen Pipes – Frozen pipes are a common Chicago and Crystal Lake plumbing problem. The best cure for a frozen pipe is to turn faucets on and allow the pipe to warm by opening cabinet doors under sinks to get the pipes exposed to warmer air. Using a hair dryer, electrical heat tape or space heaters may help thaw frozen pipes but NEVER use an exposed flame. You are far better served by insulating potentially troublesome pipes ahead of time. If frigid weather is expected over multiple days, let faucets drip slowly to keep pipes from freezing. If pipes are freezing, any further expansion can lead to them bursting, causing serious problems and damage.

When it Comes to Common Plumbing Problems, Know When to Hold ‘Em and Know When to Fold ‘Em

At Althoff Industries, we are often called to finish a job a do-it-yourselfer has attempted themselves. If your problem is one you are comfortable in resolving, give it a go. If not, feel free to contact Althoff Industries. We are pleased to resolve Chicagoland plumbing problems.

Warm Days, Cool Nights: Seasonal AC Tips for Energy Efficiency

August 29th, 2017

This is the time of year when those of us in the Chicago area can still experience some pretty warm daytime temperatures as our nighttime temperatures begin to get downright cool. Humidity begins to drop and the air starts to feel fresher. It can be tempting to consider turning seasonal AC on and off or to only use it as needed. We may even view it as a way to save energy. That may not exactly be the result. Here are some tips to stay comfortable in the fall, while also being energy efficient.

5 Tips for Seasonal AC Energy Efficiency

Let your thermostat do the work. Rather than turning AC on and off between daytime and nighttime, let your thermostat do the work and set it two or four degrees warmer. This will allow your residential AC unit to operate more energy efficiently while not having to work too hard to bring the temperature down inside your home during those warm days.
Use fans to circulate the air. With a higher thermostat setting, it may be a little warmer in your home during hotter early fall days. This is a great time of year to use your ceiling or oscillating fans to circulate the air. Since your AC will be operating less frequently, the fans can offer an assist in moving the air in your home.
Opening windows may not be the best idea. Opening your home’s windows can be tempting this time of year but if someone in your household suffers from allergies it could cause problems. It can also cause your air conditioner to work overtime if you forget to close them during warm days. An open window, even with a screen, can also be a security problem.
Change that filter. If you haven’t changed your air filter yet this summer, now’s the time to do so. Filters are inexpensive and easy to change and just maybe the single easiest thing you can do to keep your residential AC operating efficiently.
Check your outdoor unit. Fall leaves have a way of gathering around outdoor AC units. Be sure to make an occasional visual inspection of your outdoor unit making sure it stays unobstructed.

Turning AC on and off during the early fall can be tempting but it also can be hard on your equipment. By turning your thermostat up, using fans, keeping windows closed and maintaining equipment, you can get through these “tweener” months using your system efficiently.

Many times, a residential AC unit can limp into the fall, barely surviving the summer. That’s why this time of year is a good time to get an AC checkup so it will be ready to go in the spring. If you have any questions about your residential AC system or would like to schedule an HVAC checkup, please feel free to contact us at Althoff Industries. Spring, summer, fall, and winter, we’ve been keeping Chicago area families comfortable for over 50 years!

The Difference Between a Hot Light Switch and a Warm Dimmer Switch

August 15th, 2017

Your home is a marvel of independent and interconnected devices. Water flows in and out, managed throughout via a network of pipes, faucets, and drains. Water is even heated to a desired temperature. Air circulates in and out and is cooled, heated, and even purified and dehumidified. Electricity is available as easily as plugging something into an electrical socket or flipping on a light switch. Most of the time, when they are functioning properly, we take these systems for granted. It’s quite a different story when there are problems.

When there’s an issue with a component of one of these systems it is sometimes obvious. You can usually hear or see a leaky faucet. If the power is out, you know it. But there are times when a problem may not be so obvious, like when you have a hot light switch.

What is a Hot Light Switch?

A hot light switch is a simple on/off switch in a room that feels excessively or unusually hot to the touch. This is a problem because the heat is being generated from the electricity in the switch when it should be going elsewhere. A hot light switch is a fire hazard and a professional should be called as soon as possible. A simple light switch should not, however, be confused with a dimmer switch.

What is a Warm Dimmer Switch?

A dimmer switch usually includes a slider or round knob that can adjust the intensity of light in a room. As opposed to a regular simple light switch, the purpose of a dimmer switch is to manage the flow of electricity to a light. You may feel a warmth coming from a dimmer switch, but it is by design. As long as the heat being produced by a warm dimmer switch is not excessive, it shouldn’t be a problem.

When Should You Call for Electrical Help?

This depends on your level of comfort as a do-it-yourselfer. Many will still call a professional for any electric work, simply because it can be dangerous. Of course, anytime you are working with an electrical component of your home, make sure the power is off at the circuit breaker.

Beyond a hot electrical switch, you should consider calling a professional if:

The lights in your house dim when using a major appliance or when the heating or air goes on.
One socket of an electrical outlet is not working.
A light switch doesn’t connect solidly in the off or on position.
You have an old “fuse” system in your home.

“It is What it is” Does Not Apply to Your Electrical Wiring

Keep in mind, your home’s electrical system can be upgraded. If you are tired of reaching under a table or behind a dresser to get to an electrical outlet, use extension cords or if a light switch is inconveniently positioned in your home, changes can be made. Adding switches or additional outlets can add a new level of convenience to your home. At Althoff Industries, we can handle any size electrical work from replacing a hot light switch to completely rewiring your home. Ask us about our electrical outlets with convenient USB ports for charging digital devices. You may want to consider the beauty and energy savings of converting to LED lighting in and around your home. It is amazing how something as simple as a few more outlets, switches or a lighting upgrade can have such a positive impact. If you would like to discuss an upgrade call the professionals at Althoff Industries.

If you are experiencing an electrical emergency, we are available 24/7/365 and are ready to service you during an emergency.

6 Tips for End of Summer AC Maintenance

August 3rd, 2017

Most people in Chicago consider air conditioning maintenance a part of their spring or summer routine. The fact is, the spring and early fall are both good times to conduct maintenance on your AC. End of summer AC maintenance, though, can ensure your system is ready to go for any “Indian Summer” days we may yet experience and is good to go in the spring. If there is a problem or potential problem, there is plenty of time to get it repaired or order any needed parts. If a residential AC maintenance check discovers serious issues, you will have time to make a repair or replace decision. End of year maintenance, along with spring maintenance can help your AC unit run more efficiently, last longer, and reduce overall maintenance costs. What type of end of summer AC maintenance should be performed and what are some air conditioning maintenance tips for this time of year?

Your End of Summer AC Maintenance Checklist

1. Replace the Air Filter

Hopefully, this is not the first time you are replacing your AC filter this summer but even if it is, now is an important time to make sure it is done. Changing air filters frequently is one of the easiest and cost-effective ways to help the performance of your air conditioner.

2. Make Sure Your AC Unit Has Room to “Breathe”

Over the summer, grass and bushes may have grown up and around your outside AC unit. This can eventually keep it from getting sufficient air circulation. Clear out any brush, grass, and leaves from the area before cold weather arrives.

3. Clean the Coils and Condensate Line

Dirty coils and a blocked condensate line can cause a variety of issues with your outdoor AC unit. End of summer maintenance should include a thorough A/C coil cleaning. While many will choose to “broom off” or “hose off” AC coils, at least once a year these units should be professionally cleaned by removing the casing. This is best done by a professional.

4. Listen to Your AC Unit and Give It a Visual Inspection

Look for any frayed wires, rust or animal activity. Listen for any unusual sounds or rattling. Look for any outward signs of wear or damage that may have occurred during the summer, especially from mowers and string trimmers.

5. Combine Your End of Summer AC Maintenance with a Furnace Tune-Up

More and more families are discovering the value of having their residential furnace tuned up for the fall at the same time they perform end of summer AC maintenance. This gives them peace of mind in knowing their entire HVAC system is cleaned, maintained, and ready for the seasons ahead. Things can get very busy quickly in the fall, and these are two projects that can be handled early and easily.
