Terms to Know When Buying Air Conditioning Systems

Posted on AC Info November 10, 2010 by John Brescia

Buying an AC Unit for the first time can be a daunting experience, especially if you have no knowledge of what you should look for when buying these   units. In this article I will go over some of the terms used when describing a Air conditioning system. Once you know what each word means, you’ll be able to make more educated decisions and get the Air Conditioning system that is right for your home.

British Thermal Unit or BTU is the amount of heat it takes to raise the temperature of one pound of water to one degree Fahrenheit. If we’re talking about ACs it would be how much heat can be removed from the room by the Air conditioning system.

EER or Energy Efficiency Ratio: is calculated when you divide the BTU by the number of watts. The EER ranges from 8 to 11.5. If you live in a hot climate choose a rating of 10 or more. The higher the EER is, the better, since it’s more efficient, which also translates to being more expensive.

Thermostat is what adjusts the temperature of the air conditioning system. Some AC units come with remotes and features which allow you to adjust the temperatures comfortably.

Filter: The filter maintains the air coming from your AC Unit clean. Make sure the AC you choose to buy has a filter that can be easily removed and cleaned.

Fan: The fan is what moves the air into the room. Make sure the fan in your AC Unit has variable speed.

Chassis: If the chassis is fixed then the AC unit is of a lighter weight which makes it easier to remove when needed. A slide-out chassis can be found in through-the-wall units which allows it to slide easily for maintenance.
