Only a few more weeks of winter remain, but even after they're over, the beginning of spring holds a handful of chilly days. Until the weather warms up, one of the last things you want is your furnace acting up. To help you through the most common problems, Duncklee Cooling & Heating has a few troubleshooting tips. Since 1973, both residents and businesses in the Stonington, CT, area have trusted them for all their HVAC needs.

Before calling a professional, try the following:

• Replace the Filter: Dirty filters hinder efficiency. Too much dust inhibits airflow, and it can also interfere with temperature detection. If it’s too dusty and dirty, your unit may not operate properly when it reaches certain temperatures. If you have reusable filters, wash them regularly; if you have disposable ones, replace them accordingly.

• Check the Thermostat: For many people, an incorrectly set thermostat is the source of their furnace problems. Some thermostats need to be manually set to the heating feature, and even then, don't forget to set it to a high enough temperature where the furnace will start.

• Flip the Furnace Switch: If your furnace doesn't seem to work at all, it may be turned off. Many furnaces have a switch that simply looks like a standard light switch, and because of this, it's not uncommon for people to turn it off accidentally. Check the unit itself, but if it isn’t there, check the walls nearby.

If you've tried these and you're still having some issues, it's time to consult the HVAC professionals.
