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 843-252-0360 for repairs, maintenance, or new-system installation.

Air Conditioner Repair in Florence, SC 29501

“This Company does Wonderful job. Brian Tant repaired my AC unit and he was the absolute best. He was very professional and knowledgeable. He educated me on a few things I was not aware of. He did not just say this or that was wrong with the unit, he actually diagnosed it from several view points and then found the problem. He placed things that he used back in its proper place….funny but, he actually cleaned his feet before he stepped foot in my home. If I should ever need HVAC services again this company will definitely get my business. Thanks again Brian Tant!!!!! You are the best.” – Roselia P.

Air Conditioner Replacement in Florence, SC 29501

“I've worked with many HVAC vendors locally and nationally over the years in the commercial space. Where I was responsible for negotiating service contracts and overseeing service calls. When I require HVAC service for my home I always call Quality Service Co. Most recently one of my units was not cooling. I called at 9pm spoke with on call and setup appointment for the next day. Wayne arrived on time with tools in hand, after diagnosing the issue as shorted compressor. Warranty of my failed unit was checked and determined it expired last year. Already aware of supply line constraints due to COVID-19, I started getting concerned. Wayne provided me with two options replacing just the compressor or replacing the whole condenser unit. Personally weighing the options I opted to proceed with replacing the whole condenser unit to take advantage of the warranty that came with it. Pricing was inline with my expectations having past experience dealing with such. Wayne informed me to my surprise the parts were in stock and by miracle in my opinion were able to perform the work that day. Being the work is a two person job Hunter was available and the two got to work. They were able to replace the condenser unit and have the system running all before my wife came home from work. Wayne and Hunter are some of best HVAC technicians I've worked with and valuable employees of Quality Service Co.”
