Our Guide to the 5 Main Components of an AC

Have you ever looked at your air conditioner’s outdoor cabinet and wondered what the heck could be inside of it? Well, those days are gone, since we’re going to go out of our way today to explain some of the most important components of an air conditioning system. From the compressor to the blower fan, we’ll talk about some of the main categories of parts that make up the inside of your air conditioning technology, and we’ll even talk about what you can do when you encounter a problem.

Knowledge is power, and we believe that the more our customers know about their cooling technology, the better off they’ll be in the future. When you encounter a problem down the line, you’ll be able to direct a professional technician to the exact place where you believe the problem is coming from, due to your extensive knowledge of air conditioning in Boerne!

The Compressor

Let’s start with the heart of your air conditioner–the compressor. This component uses electrical energy that’s taken from your home’s power grid and pressurizes the refrigerant in your AC system. The compressor is the component that’s responsible for actually cooling the air in your system. Once the refrigerant is the right pressure, it is cycled through the rest of the system using the other components listed below!

The Evaporator Coil

The evaporator coil of your air conditioner is responsible for evaporating refrigerant. As it evaporates and turns into a gas inside the coil, it cause heat to be drawn into the air conditioner, effectively cooling the space around it. It’s kind of like using your hands and grabbing all of the heat in the air and putting it in your pocket. Your AC does this while the refrigerant is in the evaporator coil, moving quickly to the condenser coil next.

The Condenser Coil

The condenser coil then condenses the refrigerant in your air conditioner so it can release the heat that’s been stored. This is why you might feel the heat emanating from the outdoor cabinet of your AC system, since that’s where the condenser coil is. This heat just goes back into the atmosphere while your home remains cool!

The Expansion Valve

This is a lesser known component of an air conditioner, but it’s still vital to the cooling process. The thermal expansion valve is what allows certain amounts of refrigerant to enter the coil, essentially increasing the pressure and packing it together tightly. When we say that your compressor “compresses” the air in your AC, this is what we’re talking about! The thermal expansion valve is used to expand or contract the refrigerant as it travels from the condenser coil to the evaporator coil, allowing for the cooling process to begin taking place.

The Blower Fan

Once your air conditioner cools off the air inside of it, it needs to get that cool air to the rooms of your home. This is where your blower fan comes in! This component is responsible for pushing the air through your air vents and into the rooms of your home.

There you have it! A guide on some of the most important components of an air conditioning system.
