A gas fired forced hot air system runs off of natural gas or propane. The gas is sent through a hard pipe line to the gas valve which is activated when the thermostat calls for heat. When the gas valve opens the gas then travels to the firing assembly and is ignited by the glow plug. The flame heats the 'heat exchanger' inside of the furnace. The air blowing from the fan is then heated up as it passes through the heat exchanger and is then dispersed through the duct work.
We provide repair services for all forced hot air systems.
FORCED HOT AIR SYSTEMS
steps you can take before calling.
1) check to make sure you have power(make sure the curcuit breaker is not 'tripped' and that no one accidentally shut off the safety shut off switches to the unit- looks like a light switch with a red cover usually indicating it is for the system.)
2) make sure your thermostat is on the 'heat' mode and does not need new batteries: if it runs off battery power.
3)make sure you gas shut off is in line with the pipe going into the unit and is not horizontal to the floor. If your system is not easily accessible or is in your attic please do not attempt to check the components and call immediately.
In the event of a gas leak please shut off your emergency shut of switch mentioned above. DO NOT attempt to restart your system and call us immediately: attempting to restart your system could result in a fire or serious injury.
