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 Quality Service Company, we provide all the services you need to keep your AC running in top-notch shape. Call us at 843-773-2550 for repairs, maintenance, or new-system installation.

Air Conditioner Maintenance in Florence, SC 29505

“1.Quality Service Company lives up to their name. This is an awesome company with a very helpful team that gives "quality service" to their customers. 2. Domingo does a top notch job of maintaining both of my HVAC units twice a year. He's friendly and very thorough…this visit he even helped me out by clipping some of the branches that had grown up around the units that I couldn't get to…AND he kindly, without being asked, changed an air filter for me that was out of my reach. That's the kind of customer SERVICE that will keep me as a loyal customer! 3. While cleaning my units this time around (you can imagine what a job that is with the 4 dogs and 2 cats I have inside), Domingo noticed that I would benefit from having an air purifier and he was RIGHT! Boy have I noticed a huge difference after having the Bi-Polar Air Purifier installed on the downstairs unit. I am 100% satisfied with the friendly service and quality products I've received from Quality Service Company.”

– JENNIFER P.

Air Conditioner Repair in Florence, SC 29501

“The air conditioning has not been working properly in the new office here since 2013. We originally requested for it to be repaired previously, but were told it could not be repaired. Finally, a new technician, Domingo Hernandez, discovered the problem and fixed it. This problem should have been fixed years ago. We are truly grateful and appreciative of the fine job that Mr. Hernandez did for us today! You would do well to keep him with your company due to his excellent work skills, honesty and professionalism. We would prefer that he do any service work for us going forward if possible.
