How Does an A/C System Keep Your Home Cool?

Posted: June 21, 2021

Did you know your air conditioning system not only blows cool air into your home, it pulls out warm, humid air out also? Here is a simple explanation about how that happens.

  • Within your A/C system are two coils – an aptly named evaporator coil (located inside your house) and a condenser coil (located outside your house)
  • Traveling within and between these coils is refrigerant – a chemical that has the ability to change from a liquid to a gas very quickly, transferring heat in the process.
  • Passing along the indoor evaporator coil, the refrigerant absorbs heat from the surrounding indoor air, leaving cooled air behind for redistribution to your house.
  • Meanwhile, the refrigerant – now a warm gas, thanks to the heat it has drawn from your air – travels to the outdoor unit, where the condenser coil “squeezes” all the heat out of the refrigerant, turning it back into a liquid.
  • The compressor’s fan then pushes the heat it has gathered into the outdoor air, while the cool liquid is recycled and sent back to perform its heat transfer duties once again.

These are just the basic principles. The process is a little more complicated than that – which is why you need a professional cooling technician to service your home A/C unit every year to make sure your cooling equipment keeps working properly.

Expert A/C Maintenance and Repairs

A properly installed and maintained air conditioning system will have fewer breakdowns than one that has been neglected. That’s why we offer all the same NATE-certified expertise and money-saving services that we provide for heating equipment—including service plans and tune-ups.

If you need air conditioning repair, we’ll get your system up and running again as quickly as possible. With advanced training in the latest cooling systems, the Wilson Oil & Propane team is ready to handle any cooling system repair for all brands, from simple to complex. We’ll fix your system quickly, arriving at your home with a truck full of tools and a full array of replacement parts to complete the job right the first time.

When To Replace Your Air Conditioning Unit

If you think you’re spending too much money on repairs or your electric costs keep climbing every summer, consider replacing your central a/c system. The performance and reliability of central air equipment typically deteriorates after 15 years (sooner if maintenance has been neglected).

Over time, federal energy requirements have led to major improvements in residential air conditioning equipment. The result: dramatically higher efficiency ratings, much lower energy costs and minimal need for repairs. New cooling equipment also uses environmentally friendly refrigerant instead of the harmful and expensive R-22, which is no longer manufactured or used in new central air conditioning systems.

We can perform a complete comfort analysis of your home, talk with you about your needs—and your budget—and help you choose the right size and type of system. We’ll then install it properly to ensure that your new system keeps your home more comfortable and costs less to operate than your old one.
