The furnace, often considered the heart of the HVAC system, plays a critical role in providing warmth to your home during colder months. This essential component works by drawing in cold air from your home, heating it, and then redistributing the warmed air back into your living space.

Here's a basic breakdown of how the furnace operates:

  1. Air Intake: Cold air in your home is drawn into the furnace through return ducts.
  2. Heating: Once inside the furnace, this cold air is passed over a heat exchanger or through heating coils, depending on the type of furnace. These components are heated using a fuel source, typically natural gas, propane, or electricity.
  3. Air Distribution: After being heated, the warm air is then circulated back into your home through supply ducts and vents, thereby increasing the indoor temperature.
  4. Exhaust: If the furnace is combustion-based (like those that use natural gas or propane), it also produces exhaust gases during the heating process. These gases are vented safely out of your home through a flue or vent pipe.

It's important to keep your furnace in optimal working condition to maintain home comfort during cold seasons. This requires regular maintenance, including cleaning and inspections, to ensure the unit operates safely and efficiently.
