Furnace Troubleshooting: What to Do Before Calling for Furnace Repair10/07/2015 You can’t depend on the weather in Humble, but one thing the team at Arrings A/C & Heating wants you to be able to count on is your heating and cooling system. Having a comfy home isn’t a seasonal thing, it’s something you expect all year. When your furnace is having problems you may think that means a furnace repair can be needed soon. That may not be the case. If your furnace hasn’t been its usual, stable self lately, there are some things a homeowner can do before calling in the experts at Arrings A/C & Heating. 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, it’s easy for a homeowner to forget to flip the switch, telling your heating and cooling system what you need it to do. Something else to look at while you’re at the thermostat is the battery. The majority of digital thermostats give a low battery warning, but if it’s been some time 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 complications. Not only will a dirty filter hinder your system’s efficiency and block air flow, it could also cause an abrupt breakdown. Changing the filter in your heating and cooling system is simple and it can play a major role in keeping your system running at its best. Check the Switches The first switch you’ll want to investigate is the breaker for your furnace. Sometimes a problem can be as simple as a tripped breaker or blown fuse. Check the Vents A common misconception is that a homeowner should close the vents in unused rooms. This could actually lead to a furnace repair down the road. Closed vents generate higher pressure within your duct system and cause your system to work harder than it needs to. If you’ve gone through our troubleshooting tips and you’re still having issues the team at Arrings A/C & Heating are always there for you to make sure all of your home comfort needs are met.
