DIY Furnace Troubleshooting03/06/2015 One of the most critical parts of the winter is staying snug and warm. Of course, staying comfortable is important throughout the year, but during the chilly season it is even more necessary. Winters in Phoenix are unpredictable and the coldest days can often appear on us, sometimes when your furnace is not ready. So, before you find a professional technician, here are a few things you can inspect first: Check your filter – dirty filters are one of the most common causes of unexpected furnace failures. Air has a more challenging time passing through filters once they are dusty or dirty, causing the system to switch off often times. The older the furnace, the more difficult it might be to detect the problem, while newer furnaces are created to point out clogged and dirty filters before further issues arise. Changing furnace filters every month or so can counteract these troubles and keep you comfy. See if your batteries are weak or dead – keep constant tabs on your thermostat batteries to guarantee that there isn’t a flashing low battery light or indicator 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 forget minor things like the settings of your thermostat. Double-check this crucial 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, find the breakers that operate your furnace: [Ensure|Guarantee|Confirm]48] that the switch is in the On position. 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, spot. It can easily be mistaken for a real light switch, which is why it is often the problem with furnace troubleshooting. Once it’s back On, the system will only need a few minutes to reboot. Working through these steps is an easy and effective way of ensuring the effectiveness of your furnace before you set-up a call to your Phoenix technician. If there are still problems after you have made it through these steps, you will have a much greater idea on how to inform your [[technicians|specialists|experts}69] on what the problem might be.
