No Heat? Here's what to Check Before Calling For Service
Furnace Won't Turn On? Boiler Not Heating? Before you call us for service there are few items you can check first. It could be a simple fix.
- Check That the Power Is On - Even though they are natural gas powered, your furnace requires electricity to start and keep running. Look for the circuit in your electrical panel. If the circuit has tripped and is in the OFF position, switch it back to the ON position. If the circuit trips again after resetting, DO NOT RESET IT MORE THAN ONCE, circuit breakers are a safety device to prevent an electrical fire in the event of a malfunction. Call us to inspect the furnace and electrical connection.
- Is the Thermostat Is Turned To the HEAT Position? If it is in the heat position, try turning the temperature up a few degrees to see if it turns on.
- Check the Furnace Condensate (Drain) Pan During normal operation water drains from the air conditioner or furnace into a condensation pan. If the drain for the pan is clogged the pan will fill up and trigger a float switch, which will prevent the operation of the furnace. If the float switch is up (activated), you will need to clear the obstruction from the drain line to allow water to empty and then reset the switch.
- Is the Furnace Filter Dirty? An excessively dirty and clogged filter will cause the furnace to overheat, which in turn will cause it to shut down as a safety precaution. Installing a new filter should solve the problem.
- Is the Pilot Light On? This only applies to older gas furnaces. Most newer units have electric ignition. If your pilot light is out consult your owner's manual for the correct way to light the pilot.
- Check the Natural Gas Supply. If there are other gas appliances in the home, such a gas range or fireplace, check that they are functioning. You may have an issue with your gas service.
