5 Common Central Air Conditioner Repairs

Thursday, May 18th, 2017

During the course of the summer, a homeowner may encounter problems with their central air conditioner unit. Although, most air conditioner problems only require a quick A/C repair, if a homeowner lets small problems linger or does not engage in timely central air conditioner maintenance, it could lead to a hefty repair bill. To avoid the element of surprise, our team at Althoff has put together this list of common central air conditioning repair requests.

1. Broken Thermostats

A broken thermostat can prevent a central air conditioner from operating. If the unit fails to turn on or doesn’t reach the desired indoor temperature, homeowners should check to see if the thermostat is set to the correct temperature and that it is set to cooling versus heating. If the thermostat requires batteries, they should be changed. If these A/C repair tips fail to restore the function of the air conditioner, a central air conditioner maintenance call is in short order.

2. Bad Electrical Wiring

The air conditioner may have bad electrical wiring if it turns on for a few minutes then trips the circuit breaker or if the homeowner smells something hot or burning. If this is happening in your home, it is best to turn off the air conditioner at the thermostat and the electrical panel and then call a licensed HVAC contractor in Chicago for central air conditioner maintenance.

3. Unit Fails to Turn On or Cycles Frequently

If the air conditioner cycles frequently, it can leave homeowners with high energy bills and indoor air that is still too humid. This most commonly occurs when the air conditioner is too large for the square footage of the home. However, it can also occur when cool air blows directly onto the thermostat. If the vents are located near the thermostat, try closing them to see if this fixes the problem. If the unit still cycles on and off every few minutes, it is best to call a professional HVAC technician and schedule an appointment for an A/C repair in Chicago.

If the unit fails to turn on, homeowners should check the circuit breaker on the electrical panel to see if it has tripped. If it has, it may indicate an electrical problem. If the breaker is in the on position, an electrical component inside the central air conditioner may have failed.

4. The A/C Unit Blows Warm Air

If the residential air conditioner blows warm air from the vents, it may have low levels of coolant or it could be an indication that the outside condenser and coils need to be cleaned. Air conditioners need adequate levels of coolant in order to remove excess heat from the indoor air. Once that hot coolant reaches the condenser, adequate airflow around the unit is essential for dissipating the heat. Clearing any debris and cutting back plants around the condenser may restore proper function, but if it doesn’t, the homeowner will need a central air conditioner maintenance technician to diagnose and repair the problem.

5. Low Air Flow Through Register Vents

Low air flow through the register vents could indicate that the blower motor is malfunctioning or that there are cracks and gaps in the air ducts. The first step to locating this problem is by listening to the air conditioner while it operates. If there are grinding or squeaking noises, the blower may be malfunctioning, indicating the need for an A/C repair. If the blower is operating and sounds normal, the homeowner should walk through the home and examine the air conditioning vents. If some vents are blowing cold air at a normal volume and other vents have little to no air flow, it could indicate the need for an air duct repair service.

5 Reasons Air Conditioner Maintenance Inspection Saves You Money

Wednesday, May 17th, 2017

A regularly maintained air conditioner is one that is working efficiently, which in turn helps homeowners keep utility bills down. Spring is the optimal time to schedule an inspection–before the high heat of summer returns. Here are 5 ways that an annual air conditioner maintenance inspection will help keep summer cooling costs down.

1. Improve Air Conditioner Efficiency

When an air conditioner maintenance inspection is performed, a trained expert will examine and clean all the moving parts. The coils inside an A/C unit transfer heat from the refrigerant to the outside air while the fan inside the condenser helps accelerate the removal of that heat. When the coils and fan are dirty, it slows down that transfer of heat so the air conditioner must work harder to keep the home comfortable.

2. Keep Repair Bills in Check

All the parts of an air conditioner work together to cool a home. When one part fails, it can lead to increased wear and tear on other parts which will add up to costly repairs. By scheduling an air conditioner maintenance inspection in the spring–before the cooling season begins–homeowners can locate and replace failing parts before they have a chance to cause harm to the rest of the unit.

3. Prevent A/C Failure

A spring inspection will also help prevent a major repair or even a complete failure of an air conditioning system during the hottest summer days. Every inspection includes checking all major components, including refrigerant levels, to ensure proper operation. Maintaining proper refrigerant levels is essential, and many homeowners do not realize that their air conditioner is low on refrigerant before it’s too late.

A slow leak will cause a slow deterioration of the A/C unit. The early signs might be a slight increase in energy bills as the air conditioner must work harder to compensate for the low refrigerant level. As the season wears on, homeowners may begin to notice warmer air from vents or that the air conditioner seems to be running more often. If left unresolved, low refrigerant levels can cause the air conditioner to stop working altogether, or even damage the compressor motor–a very costly repair.

4. Extend the Life of Your Air Conditioner

A well-maintained A/C unit can last up to 20 years while a neglected one could fail in as little as 10 years. An annual A/C inspection will ensure that the unit is clean, that moving parts are operating correctly, and that ideal fluid levels are maintained. An air conditioner is no small investment; proper maintenance will ensure that investment is a sound one.

5. Warranty Compliance

A manufacturer’s warranty provides peace of mind for homeowners when installing a new air conditioner. However, most manufacturers require proper maintenance for that warranty to remain in effect. Plus, if there are problems with the air conditioner that are covered by the warranty, finding and resolving those problems while the A/C unit is still under warranty is essential.

Long-Term Savings with Regular A/C Inspections

Keeping an air conditioner running smoothly will not only provide homeowners with a comfortable home, but it will also help keep energy and repair bills low. We offer several options for scheduling A/C service including no-hassle memberships that include pre-scheduled inspections and a discount on covered repairs. Ready to start saving?

6 Tips to Maintain Residential Air Conditioner Peak Performance

Monday, May 15th, 2017

Homeowners rely on their air conditioner to work reliably and efficiently all summer long, so when a unit fails, it can lead to uncomfortably living and sleeping conditions. Learn how to keep you’re A/C unit operating efficiently all summer long with these tips.

1. Keep the Heat Off the Thermostat

An air conditioner’s thermostat keeps indoor air temperature constant. It is important to note, though, that a thermostat temperature sensor is located within the thermostat. For this reason, all heat producing appliances, including lights, should be kept away from the thermostat as they lead the sensor to think it is warmer inside the home than it actually is and consequently activate the air conditioner to run. An air conditioner that runs too often, can lead to excessively high cooling bills and decrease the performance of the high efficiency A/C unit.

2. Program Programmable Thermostats

Programmable thermostats allow homeowners to pre-program their air conditioners, according to the time and whether it’s a weekend or weekday. According to Houselogic, homeowners could save as much as $180 a year by keeping their thermostats programmed. Energy Star recommends keeping thermostats set to 78 degrees while occupying the home, 85 degrees while everyone is at work or school and 74 degrees while sleeping.

3. Keep the Air Flowing

Air conditioners need air in order to function at their peak performance. Homeowners should regularly change or clean the a/c air filter and keep the outdoor condenser area clean and free of debris. Failure to perform these common maintenance items can dramatically reduce the performance of the home’s high efficiency A/C system.

4. Consider a Duct Inspection and Sealing

Air ducts that are leaky with holes, cracks and separated seams allow cool air out of the ducts and warm air into the ducts. This dramatically reduces A/C peak performance and may cause some rooms in the home to feel hot and stuffy. Exceptionally dirty air ducts slow the air flow and result in dirt, dust and pollen being forced airborne, which can reduce indoor comfort and create high energy bills.

5. Take Advantages of Weatherization Services

Many utility companies offer free weatherization inspections that come with detailed reports of the home’s current energy efficiency and recommendations for residential energy efficiency improvements, like sealing doors and windows and investing in a high efficiency A/C.

6. Licensed Residential HVAC Contractor Inspection

Lastly, homeowners should consider hiring a licensed residential HVAC contractor to conduct a thorough inspection. Licensed HVAC contractors are educated and trained on helping residential air conditioners maintain their peak performance and reliability. Licensed cooling technicians, can inspect all types of air conditioners, perform repairs and provide useful tips on how to achieve A/C peak performance.

7 Air Conditioner Maintenance Tips for Homeowners

Monday, April 24th, 2017

Is your air conditioner ready for hot weather? While there is no substitute for an HVAC tune-up, inspection and cleaning performed by a professional, there are simple things you can do throughout the spring and summer to keep your A/C unit in good shape.

Here are seven summer air conditioner maintenance tips that homeowners can perform to stay cool during seasonal heat waves.

1. Air Filter Maintenance

One of the easiest air conditioner maintenance tips is also one of the most important. You should check your central A/C air filter every month and change it if it’s dirty. Not sure? Hold it up to the light—if you can’t see through it, it needs to be changed.

In many cases, this works out to an air filter change every 60 days—90 days at the maximum. If you have pets in the home or an excess of dust, you may need to change your A/C filter every 30 days.

Why is changing your air filters so important? A clogged or excessively dirty air filter can restrict air flow to the unit, causing it to work harder than it should. It may even overheat, leaving you overheated on a hot summer day with no A/C.

2. Remove Obstructions From Around Exterior Condenser

The outdoor condensing unit needs to be free and clear of obstructions in order to operate efficiently. All plants, trees, flowers and shrubbery should be planted and cut back to between two and three feet in order to ensure that the condenser gets maximum air flow.

If there is visible dirt, debris, dust, pollen or leaves on your condensing unit, you can use a soft broom or shop vac brush attachment to gently remove it. Always move in the direction of the fins—they are easily bent out of shape. You can also used gloved hands to remove larger pieces of debris. You need to completely turn off the power to the unit when doing this kind of maintenance. Turning off the thermostat isn’t enough—you never know when someone in the house might decide to flip it back on!

Contrary to popular belief, you shouldn’t just spray water on the outside of the unit with a hose in order to clean it. This will force the dirt and debris further into the unit’s coil. A proper condenser cleaning involves removing the panels and top of the unit so the coils can be cleaned from the inside out. This cleaning should be part of your annual professional maintenance tune-up.

The Trane website has a helpful explanation of what you should expect from your yearly air conditioner coil maintenance.

3. Don’t Close Central Air Conditioner Vents

Central air conditioners are designed to work as one cohesive unit and this includes the vents and ducts inside the home. They need air to operate. Completely closing an air conditioning vent can result in the A/C unit freezing up.

For efficient A/C operation, you should check that vents in the home are not blocked. In unused rooms, partially closed vents are usually sufficient to keep air flow operating effectively.

4. Pay Attention to the Sun and Outdoor Temperatures

During the hottest part of a summer day, keep your house cool by closing blinds and curtains. This helps prevent your air conditioner from working harder than it needs to in order to cool the home.

5. Invest in a Programmable Thermostat

Most programmable thermostats allow homeowners to set temperatures according to the time of day and also whether it’s a weekend or weekday. For optimal temperature control, homeowners should set the coolest temperatures for the times when they are home and awake. Set your thermostat to a warmer indoor temperature during times when you anticipate being out of the house to save money on cooling bills and reduce the workload on your A/C unit.

6. Evaluate Your Doors, Windows and Ductwork

Drafts around closed exterior doors and windows are a sign that warm air is getting in and cool air is getting out! Save money on your HVAC utility bills by having drafts professionally sealed. If certain ducts are blowing warmer-than-normal air or air flow is occurring through the duct when the A/C unit is not running, call a professional HVAC technician to evaluate your ductwork and seal any cracks and holes.

7. Preventive Maintenance

Scheduling preventive maintenance for your central A/C unit is the best way to make sure you’ll have reliable and efficient cool air all summer long. During an A/C maintenance inspection, a professional HVAC technician will examine all critical components of the central air conditioning unit, thoroughly clean the coils inside the unit, check refrigerant levels and recommend any needed repairs.
