How To Tell If There Is Mold In My Furnace

CategoriesNews / Products

Lately, we’ve been hearing from a lot of our customers that other HVAC companies have been using “mold in your system” as a scare tactic to push them into booking service or new system installation. We thought it would be a good idea to educate on how to tell if there actually is mold in your furnace, so you aren’t taken advantage of. Here are some of the telltale signs.

Visual Inspection
Although you may not have the knowledge required to look inside your air conditioner, furnace, or ductwork, you can still perform a visual inspection. The best way to check if you have mold in your furnace or air conditioner is simply to look at them. Pay close attention to the joints around the housing and look for any signs of visible mold. You should inspect the outside of your air conditioner coil which sits above your furnace. If you have a service door in front of your air conditioner coil, you can open it up and take a look to see if the coil or condensate pan are clean and free from mold. You can also remove a couple of register covers around your home and peek inside with a flashlight to check for signs of mold in your ductwork.

Without going out of your way to check, the easiest way to tell if you have mold in your furnace is to make a note of any noticeable odours in your home. It’s easy to become acclimated to the smells inside your house, even if they are harmful, so the best way to check if there are unpleasant odours is to leave for an extended period and then return. If you notice any musty or mildewy odours in your home, there is a good possibility that you have a mold problem.

If you are concerned that you may have a mold problem, evaluate the moisture content in your home’s air. Mold thrives in warm damp environments, so if you have excess moisture in the air in your home, take note of the sources and try to come up with a solution to reduce those levels. One of the main sources of mold growth is an improperly functioning HVAC system. If you suspect you may have mold in your furnace and air conditioner that has spread to the rest of your home, contact a licensed professional to service your system.
