Why the Compressor in Your AC Is Crucial

Monday, September 9th, 2019

air-conditioners-on-slabsAll the components in your home’s AC are important. If one or more isn’t working correctly, it affects system performance.

  • A miscalibrated thermostat causes improper cooling.
  • A frozen evaporator coil reduces how much heat the AC can absorb.
  • A broken fan motor stops air circulation.

The compressor, however, has special importance. Think of it as the engine for the entire air conditioner. It consumes the most power, and if it doesn’t work, the air conditioner cannot do its job. Period. Plus, the compressor costs more to replace than other components, so a failed compressor is a Very Big Deal.

How Long Should My AC Stay Running?

Monday, August 26th, 2019

spinning-fan-closeupOne of the most common reasons customers call our HVAC technicians for air conditioning repair in Chicago, IL is when they have an AC that’s turning on and off almost constantly over a short time. This is known as short-cycling, and there are many different potential causes:

  • A clogged air filter
  • Undercharge of refrigerant due to leaks
  • Leaks in the ventilation system
  • AC is too powerful for the space
  • Dirty or iced-up refrigerant coils

Short-cycling is both a symptom of a problem and a problem on its own since it significantly increases the workload on the air conditioner. Parts wear down faster, cooling bills rise, and the system will end up needing an early replacement.

But how long should an air conditioner’s cooling cycle last? Understanding this is important so you can know when you’ve got an AC that’s short-cycling.

The Midsummer Stress on Your AC Can Mean Trouble

Monday, July 29th, 2019

thermometer-going-redThe peak heat of the summer season means some pretty tough days when you’re outside. When you’re in your house with your dependable air conditioning system, it’s much different. The AC sends around cool air to the rooms and maintains a pleasantly cool and comfortable environment.

But your air conditioning system has to do a large amount of work to keep your house at a comfortable temperature when the heat outside is so intense. More heat outdoors means heat moves faster inside your house, and the AC must run for longer periods to keep the temperature at the setting you want. This is why we recommend keeping the thermostat setting as high as you find comfortable, since the smaller the difference between indoor and outdoor temperatures, the slower heat moves indoors.

But no matter how you set your thermostat, your central AC is under a great deal of work stress at this time of year—and this may lead to problems requiring air conditioning service in Chicago, IL.

What Is a “Hard-Starting AC” and What Can I Do About It?

Monday, July 1st, 2019

You’ve probably experienced a car that has trouble getting started on a chilly winter day. The engine grinds, but it takes a few times before it turns over. This is an example of “hard starting.” It can happen to any type of machinery that uses motors, no matter if it’s powered by natural gas, petroleum, or electricity.

Hard starting is a problem you might encounter with your air conditioning system. Although a hard-starting AC can continue to work at providing cool air to a house, it’s not good for the system, it drains excess power, and it can eventually deal a fatal blow to the air conditioner. A hard-starting AC will make noises at startup and have trouble at how fast it can cool down the house.

The Overheating Air Conditioner: How to Prevent It

Monday, June 18th, 2018

thermometer-going-redAn overheating air conditioner is a tragic story. Your AC has only one goal: to make you feel cool and happy. Your AC will stop at nothing to achieve this, even if it means burning itself out in the process.

Overheating occurs when one or more of the AC’s components are not working the way they’re supposed to. The system will work extra to compensate for the damaged components, and that will lead to excess energy consumption followed by overheating. If you’re lucky, overheating will do no more than trip your circuit breaker. If you’re not so lucky, your AC will do its best before sadly breaking down.

Overheating can be prevented with regular maintenance and tune-ups. Below are some of the first services a professional HVAC contractor will perform to keep your AC from overheating.

Odd Noises That Can Warn You Have an AC in Need of Repairs

Monday, July 31st, 2017

shocked-by-loud-noiseOne day in the future, consumers may have access to HVAC systems equipped with powerful artificial intelligence programs capable of diagnosing malfunctions early and altering homeowners to the problem—along with instructions of exactly what’s wrong and how to call a technicians to ask for help.
