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 Walker Air Conditioning & Heating, we provide all the services you need to keep your AC running in top-notch shape. Call us for repairs, maintenance, or new-system installation.

We woke to no AC and called Walker Air conditioning before they opened up for business and promptly recieved a return... call. I spoke with their office and explained our ac issues the had me scheduled for an early afternoon appointment the same day. They called when they were on the way and were there on time. The technician was friendly and polite and quickly assessed the AC system and explained everything to me before they made the repairs. The showed me the damage part and the replacement one and explained the warranty. They even took the time to explain the basic system maintenance needed to keep my unit up and running efficiently. Thanks The Olson'sread more

Since our AC started having problems almost a year ago, we have gone through horrible experiences with four different... AC companies...to the point of total cynicism about the industry as whole. I found out about Walker on the radio and from my initial conversation with Cory, I had a feeling these guys were different...I was right. Cory walked me through every step of the process, keeping his word at every turn. The installation team performed the installation with military professionalism. Then a couple of weeks later, the quality control team, lead by Derek and his new team member, Derrione came to the house and went through the entire system with a fine-tooth comb, making small adjustments to make sure everything running optimally...They were professional, courteous, and went above and beyond to make sure we were taken care of. To say the Walker Team has restored my faith on the existence of honest brokers in the industry is an understatement. Thank you guys!read more

We used Walker in 2011 when we moved and needed new HVAC systems. They installed 2 units and did a great job. We have... maintained an annual service contract and used them for any service repairs. They typically are able to get me on the schedule within a day or two.read more

We have a unique home layout due to add-ons done over the years and almost no room was comfortably heated or cooled.... When it was time to replace our old unit, we got multiple bids, and, in the end, we chose Walker AC & Hearing. Mark and Cory thoroughly discussed our needs and designed a system adding new returns and improved duct paths. The new system is extremely quiet and energy efficient. Best of all, our entire house is finally comfortable! I highly recommend Walker AC & Hearing.read more

We have used Walker for years because the technicians who have serviced our properties have always been extremely... competent, courteous and punctual. In fact, we have developed a personal relationship with the senior technician who has serviced our accounts for years, which says a lot for a service provider and its employees. Of equal importance, Walker’s prices are quite reasonable.read more
