Common Furnace Problems and How to Fix Them

Before you call a professional, there are some quick things you can try. First, you need to check if you need a filter or a battery replacement. After that, follow the steps below.

1. Thermostat Issues

More often than not, the real problem is with the thermostat when we think the issue is with the furnace. So, check these things in your thermostat first and see if that works.

Power – Make sure your thermostat has enough juice to send a signal to your HVAC system. Take a look at its front panel to see if there is a short battery signal.

Dust – Older electromechanical thermostats sometimes require a little dusting. Be sure to rotate the bimetallic coil and contact plate. If your Q-tips are not broken into small gaps, a small piece of soft paper should work. Make sure your thermostat is not in direct sunlight.

Balance- It is important for your thermostat to function at a perfect level. Use a level gauge so that the thermostat works properly. This is especially important for older thermostats that rely on mercury switches.

Anticipator– If you do not have a digital thermostat with a mercury switch, you may need to adjust the waiting time. Remove the front and locate the small metal plate that goes from shorter to longer, turning the alarm to the “shorter” side.

Setting – This may seem obvious, but make sure your thermostat is set to “warm”. Turn the thermostat to the “automatic” position and wait approx. 30 minutes. Restore power, then return power to “hot” to verify that this “reset” is correct

2. Power

If there’s no power in your furnace, check your fuse box for any broken or damaged fuses. There can also be a separate power switch beside the furnace. Turn it on. If the circuit restart fails, you will probably have to connect with some professional, i.e. if you have the power, but the furnace still does not work.

3. Dirty Filter

It is important to replace the HVAC filter every 30-90 days, depending on the type of filter you have and how often you use your filter. Change it periodically to improve air quality, and indoor air conditioning.

These are the primary issues that users face with their furnaces. These tips should help you in a quick fix to related issues of a gas furnace. If however, these tips do not work in solving the issue that you are facing, probably you’ll do best of you leave the fixing to a reliable heating installation Bloomfield MI.
