Why Your Furnace Needs To Be Repaired
Your furnace is going to breakdown from time to time. It's best to know the reason why your furnace can breakdown to help troubleshoot and make the repairs yourself to prevent the hefty repair bills, or being left in the cold for too long. Read on for reasons why your furnace may need to be repaired.
Failure To Maintain Your Furnace
If you fail to maintain your furnace properly, it could breakdown more often, or you could experience issues sooner than if you did maintain it properly. Proper maintenance includes cleaning the furnace before, during and after the cold weather season, having your ventilation system cleaned, and having your system inspected by a professional HVAC technician. Maintaining your system can help prevent breakdowns. Schedule an inspection each season with a professional technician, and clean your system yourself using a shop vacuum. Turn off your system and the gas before attempting to clean your system.
Clogged Air Filter
If your air filter is clogged with dust and other debris, your furnace isn't going to get enough air. When this happens, your system will shut down and will not restart. Always change your furnace filter routinely every other month. Keep track on a calendar, or set a reminder on your cell phone if you need to. Change the air filter with a brand new one, don't attempt to clean the old one and reuse it. If your system shuts off, you can swap the air filter with a new one, then reset the high limit switch. Your furnace should turn on after you do this.
If your furnace isn't working, check your thermostat. There is a chance that your furnace isn't the problem at all and it's your thermostat instead. If this is the case, you can check your thermostat to see if it's on, try adjusting the temperature setting, test the wire at the back of the thermostat, and also check that there are batteries in the thermostat. If you see a problem with your thermostat, and adding new batteries didn't fix the problem, you may need to replace the thermostat. Replacing your old thermostat is not too difficult, but be sure to turn the power off to your system before you disconnect any wiring. Connect the wires to the new thermostat and add batteries. Check to see if this fixes the problem.
There can be a number of reasons why your furnace isn't working, but knowing a few things to check to troubleshoot the problem can be helpful information.
