On a cold winter’s day, the last thing you want to deal with is a home that is chilly and unwelcoming. Depending on the weather, an unheated house can even be a serious health risk. Fortunately, by identifying furnace problems and getting them resolved by a professional, you can keep your house safe and comfortable. Here are three common problems and how to avoid them.

Furnace Issues & What They Mean

1. Malfunctioning Thermostat

If your thermostat isn’t working properly, the furnace may kick on randomly throughout the day or not turn on at all when the interior temperature of your home drops. Malfunctioning thermostats can drastically impact your monthly heating bill. At the start of the cold season, always check the schedule and settings on your thermostat; monitor it regularly to see if it operates when it should.

2. Dirty Filters

The indoor air can become laden with pollutants from cleaning, cooking, and everyday living. Since your HVAC system is designed to recirculate and filter air, a dirty screen can cause frequent cycling, poor airflow, or even a damaged furnace. Check your filters frequently, and replace them every two to three months.

3. Broken Limit Switch

Your furnace’s limit switch is designed to start the burners of the unit before the air starts blowing through your home—that way, the unit doesn’t circulate cold air. Unfortunately, if the limit switch is damaged, the furnace might circulate cool air, not turn on at all, or stay on when your home is already warm. Pay attention to the unit’s responsiveness and report new issues to an HVAC professional.
