How Heating Works

Central heating systems have a primary heating appliance, such as a furnace, typically located in your basement or attic. All furnaces consist of four main components: 1) burners that deliver and burn fuel, 2) heat exchangers, 3) a blower and 4) a flue that acts as an exhaust for gaseous by-products. Depending on your situation, region and needs, you can choose from heating systems running on either gas or oil as fuel, or a hybrid packaged system that can use both fuel types.

Combustion gases are generated by the burners in your furnace and passed over a heat exchanger. Air from your home blows across the heat exchanger to be warmed. It is then blown through a system of ducts to distribute around your home. (See picture below)

During the summer your heating system works with your central air conditioning. Air is cooled as it’s blown over your air conditioning unit’s cooling coil, often attached to the exhaust of the furnace, and then sent over the same air ducts throughout your home.

Tune-Up/Preventive Maintenance:

• Service Includes:
• Check for monoxide emission
• Inspect gas valve, lines, and connections for leaks
• Check burners and heat exchangers
• Inspect ductwork and flue pipe for leaks
• Inspect indoor blower motor and wheel
• Check unit wiring and electrical disconnect
• Inspect ignition system and assembly
• Inspect thermostat (with calibration if need)
• Coil cleaning for Heat Pumps
  
  
• Benefits:
• Improved system performance
• More energy-efficient operation
• Prolonged system life
• Improve system safety
