DIY Furnace Troubleshooting03/06/2015 One of the most important parts of the winter is staying cozy and warm. Of course, staying comfortable is critical throughout the year, but during the winter it is even more essential. Winters in Lexington are unpredictable and the chilliest days can often appear on us, sometimes when your furnace is ill-equipped. So, before you find a specialized technician, here are a few things you can check first: Check your filter – dirty filters are one of the most common causes of unexpected furnace failures. Air has a more challenging time traveling through filters once they are dusty or dirty, causing the system to switch off sometimes. The older the furnace, the harder it might be to notice the problem, while newer furnaces are meant to pick up on clogged and dirty filters before further issues arise. Changing furnace filters every month or so can ward off these issues and keep you comfy. See if your batteries are weak or dead – keep continuous tabs on your thermostat batteries to ensure that there isn’t a flashing low battery light or sign on your thermostat. If there is, it’s time to replace out the batteries on your thermostat. Ensure that your thermostat is set to “heat” – it can be easy to overlook little things like the settings of your thermostat. Insure this vital 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 operate 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, change 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, spot. It can definitely be mistaken for a real light switch, which is why it is frequently the difficulty with furnace troubleshooting. Once it’s back On, the system will only require a few minutes to reboot. Walking through these steps is an easy and effective way of ensuring the productivity of your furnace before you make a call to your Lexington professional. If there are still problems after you have gone through these steps, you will have a much wider idea on how to update your [[technicians|specialists|experts}69] on what the issue might be.
