Cleaning your HVAC system may seem like a daunting task for most people, but is a readily acceptable challenge for DIY junkies. If you are one of those guys who always got into trouble for taking machinery apart, or crawling into small, hard-to-reach spaces as a kid, this DIY cleaning option could be the perfect solution for you.

A lot of people use DIY fixes for household maintenance and basic repairs. It’s a hobby that saves money and you could learn a new trade. Here are a few pointers on how to clean your air ducts properly on your own.

Necessary Equipment

  1. Brushes: You don’t need high-tech rotary brushes when cleaning your own HVAC system. A simple stiff brittle brush (like the ones we use to clean toilets) will do.
  2. Vacuum cleaner: Basic household vacuum will work fine, especially if you can attach a good hose to it.
  3. Furnace Filter: In most cases, the furnace filter will need to be replaced after the exercise.

DIY Cleaning Guide

It is good to note that there are some areas you will not be able to reach on your own. This DIY solution is definitely a cheap ac duct cleaning option. It will help you reduce the frequency of calling in the professionals, but may not eliminate the need completely.

  1. The first thing you need to do is to cover up the supply registers so that any dust you agitate or blow out does not end up back in the rooms. You can do this by lifting the registers and wrapping them with paper towels, then setting them back in place.
  2. Turning on the fan is the next step as it will help to blow out any dirt you agitate with your brush.
  3. Keep the old furnace filter on while cleaning so that the dislodged debris does not find its way into the fan motor.
  4. Gently bang on or tap the ducts you can access in order to loosen any dirt that may be stuck to their walls.
  5. Open the supply registers one at a time and push in the vacuum cleaner hose to suck out any dust blown by the fan. Use your brush to scrub off any dirt fixed to the duct walls. After that, take out the paper towels and clean the registers before screwing them back in their positions.
  6. Switch off the power supply to the furnace and open up its panels to access the blower and return air boot sections as well as the furnace fan. Go to work on the dust built up using your vacuum and brush.
  7. Finally inspect and change the furnace filter.

This exercise will enable you to clean out more than 75% of the dirt accumulated in your air ducts, significantly improving the quality of air in your home. Remember, this does not totally eliminate the need to call in professionals once in a while.
