Air Conditioning Basics

The four main components to your air conditioner are:

Condenser: The condenser is the outside metal unit and where the gas from the compressor is condensed into a liquid. The gas entering the condenser is very hot. The temperature is then lowered, so the gas can convert back to a liquid.

Compressor: The compressor is inside the condenser. It circulates the pressurized refrigerant, to concentrate the heat, and changes the low pressure gas to high pressure.

Evaporator: The evaporator is the part of the system inside the home. In simple language, it absorbs the heat from your home.

Expansion Valve: The expansion valve controls the amount of refrigerant in your system.

All of these pieces are connected by a copper tube that handles refrigerant, creating a closed loop. Heat is collected in the evaporator, sent outside to the condenser. The heat is removed, and the cool air is recirculated back into your home.

AC Facts

An Air Conditioner Doesn’t Create Cool Air.
What happens in the AC process is actually the removal of heat from the air. Your AC uses a chemical called refrigerant to remove heat and transfer it outside. The warm air runs through the lines and coils in your unit and goes from liquid to gas and back again. During this process, the refrigerant removes the heat and transfers it elsewhere so that when the air comes out the other side, it is cool.

Your AC Will Remove Humidity.
Lower humidity helps the overall comfort level in your home by making you feel cooler, even if the temperature is the same.

Your Air Filter Needs To Be Checked And Replaced Every Three To Six Months.
(depending on the manufacturer’s recommendations)
A dirty air filter restricts your air flow, which reduces efficiency, costing you money, and over time can put stress on your unit and could cause a costly repair.

Maintenance, Maintenance, Maintenance.
Your air conditioner needs regular checkups to keep it running in tip-top shape. Having regular annual preventative maintenance will bring your system longer life and fewer breakdowns over all.

SEER
The Seasonal Energy Efficiency Ratio (SEER) measures air conditioning and heat pump cooling efficiency, which is calculated by the cooling output for a typical cooling season divided by the total electric energy input during the same time frame. A higher SEER rating means greater energy efficiency.

At Dr. Cool, we provide all the services you need to keep your AC running in top-notch shape. Call us at 253.863.5665 for repairs, maintenance, or new-system installation.

Air Conditioner Installation in Sumner, WA 98352

“I called Dr. Cool for an estimate for central AC for our home. I had gotten a few estimates from other companies, but when Mark came by the house, he was knowledgeable and showed me everything available. He told me how the work would be done, explained the warranty, financing options…basically everything I had a question for, Mark answered it completely. He told me when they would come by to install the unit…they showed up right on time…the crew was really professional. Did a great job..cleaned up perfectly. I am not often impressed, but Dr. Cool and their great team impressed me, and I would recommend them to anyone who needed AC or heat work done on their home.”

Air Conditioner Repair in Sumner, WA 98352

“Dr. Cool Heating & Air Conditioning, located in Sumner, WA is a quality and honest business. We had two other service companies take a look at our air conditioning problem. Both gave us bad repair info and very costly estimates. Thank goodness we pressed on and got a third opinion from Dr. Cool Heating & Air Conditioning. The service tech took an in-depth look and discovered it was a simple fix; just needed to replace a capacitor. He was in and out quickly but took the time to check everything out thoroughly. The other companies wanted to spend thousands for the fix, even suggested replacing the entire system. It was actually a couple hundred dollars for a proper fix. We were incredibly happy with this company. When we need Service or a new furnace and/or air conditioning we will certainly use Dr. Cool Heating and Air Conditioning.”
