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.

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 A Plus HVAC, we provide all the services you need to keep your AC running in top-notch shape. Call us at 413-562-0054 for repairs, maintenance, or new-system installation.

Air Conditioner Replacement in Westfield, ST 01085

“We are extremely happy with the service provided by APlus HVAC. Your team was here when they said they'd be here, they were professional and respectful. When we ran into an issue with a 'buzzing noise' after the installation, you quickly sent out a tech to see if it could be repaired, but when that wasn't possible, you worked with Carrier to get a replacement. No hesitancy on APlus' part to make it right. We are fans and are telling our friends what a great company you are!!”

“After I made the trouble service call, Keith called me back within an hour or less, and stated that he would be at my residence in about 45 minutes.
Keith was very knowledgeable, looked at all possible causes of my stated problem. He was very detail orientated, and a personable service technician.
He did a very good job, and he could service my HVAC systems, anytime an issue comes up.
This was my first service call to A Plus HVAC, Inc, and we were more than satisfied that we are using your company for HVAC Service.
