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.

“Great service! These people were fast and efficient. I barely knew they were working. The did a great job.They cleaned up after themselves, and were extremely professional. I'd recommend those guys anytime. Nothing but excellent service and attitude. I'm making this my go to for heating and air conditioning needs!”

“My call was returned very promptly, and they were available the same day. Chris was very thorough and professional. He checked all my HVAC equipment out, located the problem, and went out of his way to get everything running properly before the end of the day. He explained everything as he went, and answered all of my questions. This was my first service with Shearer’s because my old servicer is no longer in business. I am so glad that the first call I made that day(to a different company) was not returned, because I ended up finding Shearer’s!!! I honestly had better service from them than I have had for over 25 years with 2 different systems and 3 service companies!”

“Mike was super courteous and knowledgeable in helping me make a decision on how to fix my air conditioning unit. He quickly found the source of the problem and showed me why my air conditioning unit was not functioning correctly. I feel confident now in moving forward with replacing the unit. I am super happy with the service Shearer provided! He also set me up with the next step to get it replaced.”

“Was having some questions and concerns with out hvac system and Shearer was extremely fast with sending a technician out to our home. Mike was extremely friendly, knowledgeable, prompt and detailed with his work. He was able to answer every question with detail and provided me with knowledge on how to maintain my hvac system. I will certainly be giving business to Shearer for my heating and cooling needs. With being a new homeowner, trying to find honest and reliable service companies can be a real “hit or miss” experience. This has been by far, the best interaction I have had with any company. Thank you Mike, for all your help!”
