Is there anything worse than coming back home from work to find your house a frozen wasteland,? How about waking up in the middle of the night with your toes numb and your nose stuffy? If you’re home heater or furnace is on fritz, don’t panic; here are a few easy steps you can take to get back to a comfortable home and a nice warm bed. While going through the troubleshooting process, carefully write down the steps you take and their results.
Troubleshooting your thermostat:
This might seem like a no-brainer, but it is important to make sure your thermostat is in the heat position. When you turn the switch to heat, do you hear that satisfying click? Does your thermostat control your heating system and air conditioning? Is your thermostat set to a few degrees above room temperature? Your heating system will not activate without being set to at least three degrees above ambient temperature. If you have an electronic thermostat, do you have display? Are you sure the electronic thermostat’s batteries are charged? Once you have made certain that your thermostat is operational and set correctly, and you are still without heat, it’s time to check the electrical system.
Troubleshooting the electrical system:
Because some homes have a different electrical panel for the furnace.and the rest of the home, it is important to find the appropriate electrical panel in your home before following the following steps. Once you have found the electrical panel, check to see if any of the breakers are tripped. If you’re unsure about what a tripped breaker looks like, the breaker will be caught between the on and the off position. Try resetting the breaker by turning it to the off, and then to the on position. Do you have fuses? Is the furnace fuse blown? Replace the blown fuse; make sure that it is of the same size and type. Does your heating system have an emergency shut-off switch? If so, it should be located near the furnace and you should make certain that it is in the on position.
Troubleshooting the furnace service light:
Find your home’s furnace service panel; there should be a label on the furnace panel door with instructions on what how to proceed depending on the furnace service light’s behavior. Does the light blink? Slow or fast? is the light on without blinking? Is there no light at all? Your light may be flashing you a code, and you should follow the instructions on the label.
Should all of the above instructions fail, we advise you to enlist the services of a qualified HVAC technician for a heating tuneup. Don’t worry, your hard work may still pay off. When you call the technician, tell the technician what troubleshooting steps you took and what measures you tried. This will help the technician make a more accurate diagnoses of your heating system, which means potentially less expensive furnace repair.
