AC Efficiency: How to Perform Your Own Home Energy Assessment

Posted on AC Services, Blog, Community, Tips November 20, 2018

One way to know if your AC system is working efficiently is to do a home energy assessment. Here is how to do one yourself and save money!

Keeping cool in the Florida heat and humidity can be a challenge. Making sure your AC is up and running properly is one way to beat the heat. But how do you know if your AC system is working efficiently?

You can do this by performing your own home energy assessment. Continue reading to learn how to do one yourself and save money.

How to Perform a Home Energy Assessment

Follow these steps to complete a home energy audit.

  1. Search for Leaks

Leaks are one of the biggest sources of lost energy. Search your house thoroughly for drafts.

Leaks are commonly found inside the home near doors, windows, and baseboards. If you have a fireplace, check if your damper is closed properly.

The EPA estimates you could save an average of 15% on cooling costs by air sealing your home. Once you identify the leaks, seal them with caulk or weather-stripping, whichever is more appropriate.

  1. Evaluate Your Home’s Insulation

If your home has poor insulation, you will have a hard time keeping it cool. Poor insulation contributes to additional air leaks.

Also, if you have an unconditioned crawlspace or basement, make sure there is insulation between this area and the conditioned part of your home.

Due to Florida’s climate, the recommended lowest level of insulation by the Department of Energy is R-25 for areas with an existing 3 – 4 inches of insulation, R-30 for uninsulated attics, and R-13 for floors.

  1. Check Your AC’s Filter and Condition

A dirty filter will impact your AC’s efficiency. Routinely clean as well as replace your filter. This is basic maintenance you can perform on your own.

Another thing to consider is the age of your unit. If it is more than 15 years old, it might be time to replace it with a newer, energy efficient unit.

  1. Test Your AC’s Cooling Ability

One final step is to test out your AC’s cooling ability.

When the outside temperature is 80 degrees or more, set your AC’s thermostat to something below room temperature. Once it reaches the set temperature, place a refrigerator thermometer in one of the AC’s air ducts. After 10 minutes, look at the temperature and take note.

Next, find the AC’s return duct and do the same thing. Take the temperature of the return duct and subtract it from the temperature of the air duct. There should be a difference between 14 to 20 degrees.

If the difference is lower than 14 degrees, your unit might be low on coolant. If the difference is greater than 20 degrees, there might be a problem with your ductwork. In either situation, you should hire a professional to take care of your AC system.
