How Your Air Conditioning Unit Actually Works

Your air conditioning is a lifesaver on sweltering Florida days, but do you know how the unit actually works? If not, you aren’t alone; many people have no idea how this all-important appliance cools their homes.

At Del-Air, we are passionate about ACs and love educating customers on how climate control functions. If you have additional questions about your air conditioner, don’t hesitate to give our team a call.

Understanding Your AC System

You might think of your air conditioner as adding cool air to your home, but it’s more accurate to say that your AC unit subtracts heat from indoor air and transfers it outside. That transfer takes place in the evaporator coils on the interior half of your air conditioning system.

As the coolant inside the metal coils evaporates, it acts as a heat sink for the air that moves across it from the blower. Copper conducts heat readily, so the coils that contain the coolant are usually made of this metal. To maximize surface area and provide more cooling power, the copper coils have metal fins or vanes surrounding them. While copper is very effective, the cost has increased in recent years. As a result, many people are utilizing aluminum coils, which provide many of the same advantages at a fraction of the cost.

Keeping the coils clean is crucial to heat exchange. When dust and debris accumulate on your AC coils, the particles form an insulating layer that prevents warm household air from the blower from reaching the chilled metal. Fortunately, Del-Air cleans coils as part of our regular 20-plus-point tune-up. Not only do we evaluate the evaporator coil for buildup, but we also change out filters and assess blower amps to guarantee solid performance year round.

This was my first experience with Del-Air and they were prompt, professional, and knowledgeable. They were able to get me in on the same day for a maintenance visit, which I wasn’t expecting but very much appreciated. The office staff was pleasant and so was the technician that came out to service my air conditioners. Thanks…
