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 overall.

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 Cool Sunshine, we provide all the services you need to keep your AC running in top-notch shape. Call us at 303-287-1846 for repairs, maintenance, or new-system installation.

Air Conditioner Installation in Denver, CO, 80224

“We purchased a furnace and air conditioner from Cool Sunshine in Oct. of 2020. They were very professional and were able to complete the installation quickly. We started using the air conditioner in late Spring of 2021 and discovered a problem. The Cool Sunshine folks responded quickly, found the problem and fixed it. This issue was even covered by the warranty. We ended up getting some landscaping done and had to have Cool Sunshine move the air conditioner out and then back into place. Even though this was one of their busiest times (with 90+ degree days), Cool Sunshine fit us into their schedule so we didn't have to go too long without our air conditioning. The representatives that came to do the work were courteous, knowledgeable and kind.”

You will not be disappointed with the work these guys do!

We had Cool Sunshine come out and replace our a/c and furnace when the other guys we had were trying to rip us off! The other company was not only trying to sell us an older model and reduce our efficiency, they were killing us with installation costs. So happy we were fortunate enough to work with such a skilled and professional team. What we thought would take an entire day took half the time. They were also so tidy with their workmanship. We are so happy with our new unit. You will not be disappointed with the work these guys do! Thanks so much!
