DIY Furnace Troubleshooting03/06/2015 One of the most critical parts of the winter is staying snug and warm. Of course, staying comfortable is vital throughout the year, but during the winter it is even more crucial. Winters in Corpus Christi are erratic and the coldest days can often spring up on us, sometimes when your furnace is unprepared. So, before you find an expert technician, here are a few things you can examine first: Check your filter – unclean filters are one of the most common causes of unexpected furnace failures. Air has a harder time floating through filters once they are filthy or dirty, causing the system to switch off sometimes. The older the furnace, the trickier it might be to detect the problem, while newer furnaces are designed to point out clogged and dirty filters before further issues arise. Replacing furnace filters every month or so can prevent these issues and keep you comfortable. See if your batteries are weak or dead – keep constant tabs on your thermostat batteries to ensure that there isn’t a flashing low battery light or marker on your thermostat. If there is, it’s time to swap 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. Double-check this important step, especially if there was a relevant rise in temperature that may have caused you to turn off the “heat” setting. Check your switches – in your home’s circuit breaker panel, find the breakers that control 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 spots, change the breaker to Off and then reset it to On. The switch that appears to look 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 often the difficulty with furnace troubleshooting. Once it’s back On, the system will only take a few minutes to reboot. Going through these steps is a straightforward and effective way of confirming the effectiveness of your furnace before you give a call to your Corpus Christi technician. If there are still issues after you have gone through these steps, you will have a much wider idea on how to notify your [[technicians|specialists|experts}69] on what the problem might be.
