Air Conditioning Basics

The four main components to your air conditioner are:

Condenser: The condenser is the outside equipment and where the refrigerant from the compressor is condensed into a liquid. The refrigerant gas entering the condenser is very hot. The temperature is then lowered, condensing the refrigerant into a liquid state.

Compressor: The compressor is inside the outside condenser unit. It circulates and pressurizes refrigerant in the refrigerant cycle.

Evaporator: The evaporator is the part of the system inside the home normally mated to the furnace. It looks similar to a radiator in a car, often in an “A” shape. Thus, they are frequently called A-Coils. Liquid refrigerant is forced into a vapor state inside this coil of tubes. This causes the temperature to drop dramatically. Air from the home is blown across the evaporator cooling the air, removing heat from your home.

Expansion Valve: The expansion valve controls the amount of refrigerant flowing into the evaporator coil, causing a pressure drop on the discharge side of the valve. This is how the refrigerant is force into a vapor state.

All these pieces are connected by a copper tube that handles refrigerant, creating a closed loop. Heat is absorbed in the evaporator, pumped outside via the refrigerant gas to the condenser where it is rejected, then returned inside continuing the cycle.

AC Facts

An Air Conditioner Does Not Create Cool Air.

What happens in the AC process is the transfer of heat from your indoor air. Your AC uses a chemical called refrigerant to absorb heat and transfer it outside. The refrigerant runs through the lines and coils in your unit and goes from liquid to gas and back again. During this process, the refrigerant absorbs the heat from your indoor air and transfers it outside so that air distributed in your home 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 Quarterly.

(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.


The Seasonal Energy Efficiency Ratio (SEER) represents 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 All Seasons Heating and Air Conditioning, we provide all the services you need to keep your AC running in top-notch shape. Call us at 509-248-6380 for repairs, maintenance, or new-system installation.

“I’ve had trouble with what I thought was condensation and had other services come out who never solved the problem. All they wanted to do was a maintenance agreement. Why would I continue that if they never fixed my problem! It was a real issue for me.
I randomly called All Seasons and was so happy I did! Josh came out and totally solved the problem. He explained everything to us. What a relief. People are great and priced reasonable! I highly recommend Josh!
