Air Quality

Burning Oils and Candles in the Home

When liquid oils are or candles are burned in the home, it can lead to several issues with the HVAC system and the indoor air handler:

  1. Clogged Air Filters: The combustion process releases particulate matter and soot, which can accumulate on air filters. This buildup reduces airflow through the air handler and can strain the system.
  2. Dirty Coils and Components: Soot and other combustion byproducts accumulate on the blower wheel, ductwork, coils, and other components of the indoor air handler. This buildup increases friction, reduces the efficiency of the system, and can lead to overheating and premature failure of components. A residue or film resulting from the from oils and waxes can accumulate in the condensation drain pans (internal and overflow) and in the drainpipes. This causes blockages that can lead to drain clogs and water damage.
  3. Reduced Efficiency: The accumulation of soot and other contaminants on the components of the air handler reduces the efficiency of the system. This can result in higher energy bills, increased wear and tear on the system and longer runtimes.
  4. Poor Indoor Air Quality: Burning candles and oils can release harmful VOC (volatile organic compounds) pollutants and chemicals into the air, which can degrade indoor air quality. This can exacerbate respiratory problems and allergies and liver stress in occupants of the home.
  5. Potential Fire Hazard: If the combustion process is not properly controlled, it can pose a fire hazard to the home. Accumulation of soot and other combustible materials within the air handler can increase the risk of fire.

To mitigate these risks, it’s essential to ensure proper ventilation when burning candles or oils in the home and to regularly maintain and clean the air handler to prevent buildup of soot and other contaminants. Additionally, using clean-burning fuels and properly maintaining heating equipment can help reduce the potential damage to the air handler and ensure safe and efficient operation.
