DIY Furnace Troubleshooting03/06/2015 One of the most critical parts of the winter is staying cozy and warm. Of course, staying comfortable is vital throughout the year, but during the chilly season it is even more crucial. Winters in Midlothian are unpredictable and the frostiest days can often appear on us, sometimes when your furnace is not ready. So, before you ask an expert technician, here are a few things you can inspect first: Check your filter – grimy filters are one of the most universal causes of sudden furnace failures. Air has a more difficult time floating through filters once they are filthy or dirty, causing the system to shut down sometimes. The older the furnace, the more difficult it might be to detect the problem, while newer furnaces are designed to find clogged and dirty filters before further issues arise. Swapping furnace filters every month or so can prevent these issues and keep you warm. See if your batteries are weak or dead – keep incessant tabs on your thermostat batteries to make sure that there isn’t a flashing low battery light or sign on your thermostat. If there is, it’s time to switch out the batteries on your thermostat. Ensure that your thermostat is set to “heat” – it can be easy to forget minor things like the settings of your thermostat. Double-check this important step, especially if there was a relevant increase in temperature that may have caused you to change the “heat” setting. Check your switches – in your home’s circuit breaker panel, locate the breakers that run your furnace: [Ensure|Guarantee|Confirm]48] that the switch is in the On side. If it is Off or in the middle of the two sides, cycle the breaker to Off and then reset it to On. The switch that looks like a light switch should also be in the On, or Up, position. It can easily be mistaken for a real light switch, which is why it is frequently the problem with furnace troubleshooting. Once it’s back On, the system will only require a few minutes to reboot. Walking through these steps is a simple and effective way of checking the effectiveness of your furnace before you give a call to your Midlothian professional. If there are still difficulties after you have worked through these steps, you will have a much better idea on how to inform your [[technicians|specialists|experts}69] on what the issue might be.
