Whether warm or cold air is needed to be circulated throughout your home, the blower motor is a major component of your HVAC system that helps push the air through the heat exchanger to where you want it in your home.
BLOWER Motor
If it's heating season your system's heat exchanger is the mechanism that heats the air in your home. Air pushed from the blower motor is heated and then continues to the supply vents, while toxic fumes are vented through the vent pipe.
HEAT EXCHANGER
Byproducts from a gas furnace include the combustion process including nitrogen oxides, sulfur oxides and most notably — carbon monoxide. The exhaust pipe’s job is to remove these harmful gases from your home and vent them outside.

MERV 12 filters have the highest ratings for residential environments. MERV 12 filters eliminate up to 89% of particles such as dust, lint, mold spores, pollen, pet dander, bacteria, viruses and smoke. It is recommended to change the filter every 90 days. For homes that have multiple pets, change the filter every month or two.

Return vents recycle the air in your home by sucking it from the rooms throughout your house and sending it back through your HVAC system. Unlike the supply vents, you won't feel air coming through a return vent.
