Air Conditioning Efficiency and how to Improve it

Checking to make sure you're getting the most energy efficiency out of your air conditioning unit is similar to making sure your hvac is simply working properly. Knowing the basics of inspecting your system can more than save you from having to hire someone, but it can also contribute to the longevity of your system.

How to check to see if your AC is running efficiently:

Filters

Fancy filters are not a necessity. Simply buying inexpensive filters from Lowes or Home depot, and changing them every 30 days is substantial maintenance work. High dollar filters can in fact be more restrictive, and ultimately block return air which will hurt your system.

Return Air 

This is simply checking to make sure you have enough return air blowing out of your vents. If you hear a whistling noise this means that the return air is being restricted.

Freon Charge

Your system's freon should be checked once a year, and should be at about 5 degrees superheat charge for hot outdoor temperatures. If your system needs continous freon, something is wrong, and you might need a new air conditioner. It is illegal to continuously add freon to your system.

Ductwork

Make sure your ductwork is sealed tight. Usually located in attics, check to see if there are any cracks or leaks. Mastic tape or mastic seal are some of the best materials to use to assure everything is secured.

Miscellaneous Checks 

  • On your unit outside, check to make sure the coils are clear of grass clippings. Simply keeping your AC unit clean will improve its efficiency.
  • If moisture is coming out of external pipes, this is a good thing. It means that moisture is not building up in your crawlspace, but rather being pulled out of your house.
