When the temperatures drop, your home's furnace becomes one of the most vital components of your comfort system. At Lieber Mechanical, we know how crucial it is to have a reliable, efficient heating system that you can count on throughout the cold months. Whether you're looking to install a new furnace, upgrade your existing system, or schedule seasonal maintenance, understanding how your furnace works is the first step in keeping your home safe and warm.
What Is a Furnace?
A furnace is a central heating unit that generates heat and distributes it throughout your home via ductwork. Furnaces can run on various energy sources, including natural gas, propane, oil, or electricity. The type of furnace you choose will depend on your home’s infrastructure, energy costs in your area, and personal preferences.
How Does a Furnace Work?
Most modern furnaces follow a similar heating process:
- Thermostat Call for Heat: When your home's temperature drops below your thermostat setting, the system signals the furnace to turn on.
- Ignition: For gas furnaces, the burners ignite (either via a pilot light or electronic ignition). For electric furnaces, heating elements begin warming up.
- Heat Exchange: The burner heats up a metal heat exchanger, and the air from your home passes over it, warming the air.
- Air Circulation: The blower motor pushes the warm air through your ductwork and into your living spaces.
- Exhaust Venting: For gas furnaces, combustion gases are safely vented outside the home through a flue or vent pipe.
Types of Furnaces We Install and Service
At Lieber Mechanical, we work with a wide range of furnace types and brands to suit every home and budget:
- Gas Furnaces: Efficient and cost-effective in areas where natural gas is available.
- Electric Furnaces: Great for areas without natural gas; typically lower upfront cost.
- High-Efficiency Furnaces: ENERGY STAR® certified systems that reduce energy usage and utility bills.
- Variable-Speed Furnaces: Offer precise temperature control and better air quality.
