DIY Furnace Troubleshooting

Heating

One of the most important parts of the winter is staying cozy and warm. Of course, staying comfortable is important throughout the year, but during the chilly season it is even more crucial. Winters in Lexington are unpredictable and the chilliest days can often spring up on us, sometimes when your furnace is not ready. So, before you ask a professional technician, here are a few things you can inspect first:

  1. Check your filter – grimy filters are one of the most universal causes of unexpected furnace failures. Air has a harder time traveling through filters once they are filthy or dirty, causing the system to shut off sometimes. The older the furnace, the more difficult it might be to find the problem, while newer furnaces are meant to pick up on clogged and dirty filters before further problems arise. Replacing furnace filters every month or so can counteract these issues and keep you comfy.
  2. See if your batteries are weak or dead – keep continuous tabs on your thermostat batteries to make sure that there isn’t a flashing low battery light or marker on your thermostat. If there is, it’s time to switch out the batteries on your thermostat.
  3. Ensure that your thermostat is set to “heat” – it can be easy to overlook minor things like the settings of your thermostat. Verify this crucial step, especially if there was a relevant spike in temperature that may have caused you to switch off the “heat” setting.
  4. Check your switches – in your home’s circuit breaker panel, discover the breakers that control your furnace:
    1. [Ensure|Guarantee|Confirm]48] that the switch is in the On side. If it is Off or in the middle of the two positions, cycle the breaker to Off and then reset it to On.
    2. The switch that seems like a light switch should also be in the On, or Up, side. It can easily be misidentified as a real light switch, which is why it is usually the issue with furnace troubleshooting. Once it’s back On, the system will only require a few minutes to reboot.

Going through these steps is a simple and effective way of checking the productivity of your furnace before you give a call to your Lexington technician.
