3 Common Furnace Problems and How to Avoid Them


You count on the furnace in your Marietta, Georgia, home to keep you comfortable and healthy all winter long. That’s why it’s so important to keep it maintained and running smoothly. However, many homeowners neglect to keep their furnace in tip-top shape, or they call the repairman without doing some simple troubleshooting. Before you waste time and money on unnecessary repairs, here’s a list of common furnace problems and how to avoid them.

Furnace Blows Cold Air

One of the biggest mistakes that homeowners make is failing to schedule an annual tune-up. As a result, the furnace isn’t functional when the first cold temperatures hit. To avoid a furnace that blows out cold air, schedule a tuneup in late fall, just before the temperatures go down.

If the temperature changes abruptly, or you just aren’t very attentive to detail, checking the thermostat could be a quick, easy fix. Most of the time, the thermostat is set on cool rather than on heat, meaning you won’t get hot air no matter what you do. After you’ve set the thermostat to heat, make sure you have the temperature at the right level.

Clogged Filter

When the furnace filter becomes clogged, it presents a bevy of problems, including reduced efficiency, lack of airflow, and increased wear and tear on the unit. To combat this problem, make sure to change your filter at least once every 90 days, with a preference toward 30 days or 45 days.

Frequent Cycling

Cycling, or your furnace constantly turning off and on, is another common problem that costs you money and fails to provide a comfortable temperature. Most of the time, this is the result of a poor thermostat setting, a pilot light malfunction, or a clogged filter. If you find your furnace going off and on, make sure to check those three aspects.

Furnace problems are an inevitability, but by looking for these common problems, you can help avoid added costs. If you check these three problems, and your furnace still doesn’t work, it’s time to call E. Smith Heating & Air Conditioning at 678-369-8866.
