Candles and HVAC Air Filters- IAQ For Your Oregon Home

Do Candles Affect Your Hvac Air Filters in your Portland, OR Home?

Oregon homeowners often use candles for their ambiance and aromatic pleasure. While they look wonderful and smell great, can the candles you are lighting cause damage to your home’s HVAC system? Learn more about the dangers of burning candles, and what this household habit means to HVAC air filters.


The light and fragrance of burning candles can be attributed to the soot and wax produced by them. Most often, this soot and wax won’t be found in your home. Where does this wax go?

Air circulating throughout your home can pick up the wax and soot from candles. Further, It flows into your return pipes and then travels to your heating or cooling equipment. Then, It passes through HVAC filters before being conditioned and recirculated to your living areas. This is not a desirable situation for Oregon Homeowners. 

Furthermore, your HVAC air filters trap soot, wax and other contaminants in your air supply. These substances stick on the filter’s surface, and can cover HVAC air filters with a darkened, waxy residue. Heating and cooling air filters become clogged from the buildup of soot, wax, and other substances. Air cannot flow properly through this blockage.

As a result, Keep an eye on the HVAC air filters in your Portland, Oregon home if you regularly burn candles. They will need to be changed more often than you might think.

Finally, You should check your HVAC filters every month. If you notice a darkened or waxy area, or large amounts of debris, it is time to change them. Dirty filters will reduce air quality and cause strain on HVAC equipment.
