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.

HVAC System Replacement

“On 8:00 on Sunday morning, our system failed with temps going down into the teens. I called the company I had used for over 30 years. After an hour with no response and a second call (still with no response), I contacted Quality Service Co. Luckily, my system came back on so I did not require an emergency call but I still called to have Quality to check it on Monday. They called at 7:30 a.m. to set up a time and had a tech at my house an hour later. Matt determined the issue and even checked on warranty for me. We decided to check into replacement instead of repair. Allen Duffy was at my door an hour later. He presented me with a proposal including payment options and information on the complete system. We made the decision to replace. Allen ordered our new system with a promise of installation on Tuesday.

At 8:03 Tuesday morning, the team pulled in my driveway ready to begin work. The work was completed later that day. Allen also came back to help me get acquainted with the new programmable thermostat. Today (Wednesday) he came back and installed a surge protector on it. He brought all of my paperwork which included the forms for Energy rebates. They had already been filed. In addition, the installation team replaced the pad underneath the unit as well as cleaning and mulching around the unit. They also replaced the breaker in the breaker box because ours was too large.

Their work was superior and I was treated with the utmost respect and courtesy by every employee during the whole process. I cannot thank them enough for all of their assistance. Everyone helped make the process as painless as possible. I was new to their company but they treated me as if I was a long-time customer. I highly recommend them. You will not be sorry.”
