AC Air Duct Cleaning

It's the dead middle of summer and you are melting away. You could swear that the air conditioner in your home is on high, but you are still getting no respite from the cruel heat.

The only thing that you can think of is that your air conditioner has been running on high for so long that it has actually put a hole in the Ozone layer directly above our home, thus letting the suns rays cook you and your family unimpeded. That's ridiculous of course. What's probably wrong is that you're AC air ducts need cleaning.

The Need for Clean
Over time, your air ducts process a lot of air. While you most likely have a plethora of air filters in your duct system, there is still a chance that some particles escape. These particles then get stuck on the walls of your ducts, thus restricting the flow of air.

You may also have excess dust and dirt build up in your AC ducts due to cracks and holes in the ductwork system. Therefore, after you clean out your AC air ducts, you will probably want to go in there with an aerosol sealant and plug those holes. Doing so will ensure that there will be less dust entering in the future and you will have to clean your ducts even less.

The estimated saving for the process is around $300 per year (depending where you live). For some people, that means a 40% savings on their electricity bill. These are savings that will last all year round and all for a one-time fee.

How To Clean Your AC Air Duct
To perform an aerosol sealing of your ducts, follow these steps:

  1. First, measure the leak by doing a pre-seal test. This will give you an idea of just how big the leak is.
  2. Next, use foam or plastic to block off the registers, then pump an aerosal sealant into your AC duct system.
  3. Because you have blocked off all the escape routes for the air, the sealant is able to settle right where the leakage occurs, at the air duct holes.
  4. Perform another seal test to make sure you haven't missed any leaks.
