How Your Heating System Impacts Indoor Air Quality

Posted on: December 29, 2016

In Southern California, when temperatures start to quickly decline, it’s time to get your heating system back in gear. It’s important to consider how running your home’s heating system will affect your indoor air quality, especially when your furnace has been stagnate for the better half of a year.

How Your Heating System Works

  • When the temperature in your home falls under the thermostat setting, a low-voltage signal is sent to the furnace to activate the motor
  • Once the motor is activated, all the gas that is left over in the heat exchanger is purged
  • Ignition occurs to light the burner inside the combustion chamber, creating heat
  • Once your indoor air temperature reaches that of your thermostat, the gas valve will close and the burner goes out
  • The blower fan will continue to run until all the heated air is expelled through your ductwork

Furnace Filters

If your furnace filter is dirty during a heating cycle it will restrict the airflow, which means it won’t do a very good job pulling from your indoor air supply. Additionally, a severely clogged filter can stress your system components – reducing the functionality of your heating system and increasing your energy bills. Your air filter should be checked at least once a month and changed regularly during heating season.

Dirty Ductwork

If your ductwork has not been cleaned or maintained regularly, your indoor air quality – and health – will suffer as a result. Ductwork in your home has two systems; supply ducts that blow heated air into rooms and return ducts that inhale indoor air and return it to the blower. Moisture, debris, and dirt in your home will get stuck in your ductwork and become a breeding ground for molds, allergens, toxins, and other infectious compounds. Particles can end up inside your heating system, making it less efficient and degrading your indoor air quality.

You can check the quality of an air filter by the MERV (Minimum Efficiency Reporting Value). The higher the MERV rating, the cleaner your air will be. You should consult a certified HVAC contractor to make sure the filter is compatible with your heating system and it is properly installed. heating installation
