Keeping the HVAC Unit Clean Is the Responsibility of Every Homeowner

Your heating and cooling systems circulate air throughout your house, so they literally effect the air your breathe. Don’t you want that air to be as clean as possible? If you care about the health and safety of your family, your answer should be yes.


Your first line of defense against contaminated air is a filter. These need to be cleaned or replaced regularly, so make sure you are familiar with all your filter locations, including the furnace filter. At the very least, they should be cleaned twice a year. However, they may need to be checked on up to 4 times a year if any of the following apply to your household:

  • You have one or more pets.
  • You often leave doors or windows open.
  • You keep a lot of plants indoors.
  • You have a large family.
  • You smoke indoors.


The material that lines your heating and cooling system can make or break your maintenance load. The proper lining can withstand corrosion and buildup, while strengthening the walls of your duct work. Older systems may not have lining, or use plastic, which isn’t as sturdy. Plate metal is recommended for ducts, and sometimes rubber is the best material for tanks. Look into tank lining services to inspect your system and install the lining that will give your HVAC unit more longevity.

Professional Cleaning

Even if you properly maintain your filters and lining, you should bring in a professional cleaner every 5 to 10 years to thoroughly cleanse the entire system. This should be done more often if you neglect your filters. While they are in there, take advantage of the chance to inspect your system for any damage or mold, or check for any possible upgrades. This will also help to increase the value of your home.

Air carries a lot of contaminants: mold, dust, pollen, insects and even moisture. For this reason, your HVAC systems can easily become compromised without regular maintenance. You home should be a sanctuary- a good place to start is clean air!
