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 & L Heating and Air, we provide all the services you need to keep your AC running in top-notch shape. Call us at 865-856-8797 for repairs, maintenance, or new-system installation.

“Been homeowners for 20 years. We JUST used A & L Heating and Air after using a couple of other local company over the years. After seeing A & L recommended on a local site & suggestion page by another HAPPY customer I decided to give them a try. I was BLOWN away by the level of quality of this company on every level every step of the way!!!! From the courteous & knowledgeable office staff to the installers everyone was professional & helpful! I truly wish ALL services and fields of the service industry (electricians, plumbers, contractors, etc…) had experts set up to the level of professionalism as A & L (NOT JUST A CREW) as this company with the same quality of customer service they provide! We had a brand spanking new unit installed 6 years ago by a another heating & air company. I was paying that same company to have yearly "maintenance" on my unit (or so i thought) but it turns out i was being charged for services they weren't actually doing (found that out the hard way). The company sold me a unit 1 ton too large for my home and when replacing my duct work not only layed it out wrong to a fault they installed 3 different size ducts interfering with air flow and taking an unfortunate toll on our unit. With this "other" company NOT properly maintaining our unit and the poor movement of air we have struggled to properly heat and cool our home with our new unit. We chucked it up to East Tennessee conditions. Come to find out my heat condenser in our practically new unit is almost rusted through and will fail soon. This is an issue that SHOULDN'T have happend so soon in it's young life. Do yourself a favor and call A & L Heating & Cooling! You WON'T be sorry you did! Above i had to chose a service but we had our unit maintained, Duct work replaced, and a ductless mini split installed. I was able to evaluate the business in the following areas: repair, maintenance, & installation. For the first time in YEARS we've had adequate heating & air, even in these harsh Tennessee conditions! I actually get COLD in my house now! My only regret is not finding A & L SOONER!”

They explained everything to me in terms I could easily understand, showed me firsthand what I was dealing with, and followed up on their work. I’m very happy with the outcome and will definitely be recommending them to other family and friends!”

“Wanted to write a review for A&L Heating and Air. My wife and I had to replace our unit and had to find a decent company to work with. That can be a chore! Thankfully we were introduced to Aaron with A&L (several on this site recommended them actually). Aaron Sweetwood is the owner of the company and he actually installed our unit. Not every day you have the owner of a company completing your work order. Great service. Great follow through. Excellent company to work with. Highly recommend!”

“We used them for the first time today. Very pleasant to deal with on the phone and in person. The tech fixed my a.c. very quickly. He even told me how old my unit is and it's condition (I had no clue, didn't think to ask when I bought my house). I'm going to purchase their maintenance plan too. Super happy with the service.”
