If your furnace breaks down, a heating repair professional can come to the rescue. They’ll restore your system to its former cozy glory in no time. In the meantime, you may be wondering what causes a heating system to malfunction. Here are four of the most common issues a furnace faces.

How to Identify Frequent Heating Problems

1. Cold Air

It’s safe to say you don’t want cold air coming through your vents anytime before spring. Fortunately, there are a few possible steps to take in this instance. First, make sure your thermostat is set to “auto” and you have a fresh air filter. If leaky ducts are reducing the amount of warm air reaching your vents, however, consult a heating repair technician for a more detailed inspection.

If the pilot light won’t stay on, your furnace can’t produce warm air. A broken light sensor may be the issue in newer electric models. A heating repair technician will likely need to replace it. For pilot lights in older models, grime buildup and a gas leak are both possibilities. You don’t want to take chances with the latter, so always call in a professional for such a serious problem instead of troubleshooting it yourself.

2. Burning Smell

When you turn the heater on at the beginning of fall, it can produce an unpleasant burning smell. This is usually fine since the furnace is burning excess debris and dirt that accumulated during its inactive period. However, if the burning smell persists for a couple of days, replace the air filter. This is typically all that’s needed, but call for help if a few more days go by without the smell dissipating.

3. Fan Problem

If the fan doesn’t seem to be working, switch the thermostat to fan-only. If it comes on, the blower motor isn’t the issue. If this doesn’t trigger the fan, however, the problem may be electrical. A technician will be able to solve the mystery along with cleaning any buildup that might be exacerbating the issue.

4. Lack of Maintenance

Like other appliances that put in a lot of work for your home, your heating system needs regular checkups and care. From cleaning dirty components to replacing components, regular maintenance takes care of minor issues before they turn into bigger problems.
