Furnace Troubleshooting: What to Do Before Calling for Furnace Repair10/07/2015 You can’t depend on the weather in Macon, but one thing the team at Air Temperature Control wants you to be able to trust in is your heating and cooling system. Having a comfy home isn’t a seasonal thing, it’s something you need all year. When your furnace is having trouble you may think that means a furnace repair can be expected in your future. That may not be the case. If your furnace hasn’t been its usual, stable self as of late, there are a few things a homeowner can do before calling in the experts at Air Temperature Control. Check the Thermostat We have been on a job where we simply had to switch a thermostat from “cool” to “heat”. While adjusting the thermostat for the season, a homeowner can easily overlook flipping the switch, telling your heating and cooling system what you would like it to do. One thing to check while you’re at the thermostat is the battery. The majority of digital thermostats are equipped with a low battery warning, but if it’s been a while since you’ve changed batteries it may be time for a change. It’s another easy fix that could save you a repair call. Check the Filter A dirty air filter can create all sorts of problems. Not only will a dirty filter hinder your system’s efficiency and decrease air flow, it could also cause an unexpected breakdown. Changing the filter in your heating and cooling system is simple and it can play a huge role in keeping your system operating at its best. Check the Switches The first switch you’ll want to look at is the breaker for your furnace. It’s often the case that a problem can be as easy to fix as a tripped breaker or blown fuse. Check the Vents A typical misconception is that a homeowner should seal the vents in unused rooms. This could actually lead to a furnace repair down the line. Closed vents create higher pressure throughout your duct system and cause your system to work harder than it needs to.
