With the cold weather descending on the state of Florida and temps regularly falling into the low 40s, now is the time of year when you might start relying on your furnace to keep you warm. Unfortunately, it’s also the time of year when a broken furnace is most likely. Here are the steps to take when your furnace doesn’t work as it should to keep you and your family warm.
Step 1: Check that the Furnace Settings are Correct
You’d be surprised at how often a seemingly broken furnace can be corrected by adjusting simple settings. Make sure the system is set to “heat”, the fan is set to “auto”, and the thermostat is set at an appropriate temperature. More often than not, fixing a broken furnace is as simple as adjusting these common settings.
Step 2: Clean the Thermostat
If altering the settings doesn’t get your broken furnace to work properly, the next step involves making sure the thermostat itself is clear of dust. A layer of dust can impact the thermostat’s calibration, tricking the thermostat into believing it’s warmer than it truly is.
Step 3: Look at the Fusebox or Circuit Breaker
If your furnace won’t come on at all, check to make sure the fuse hasn’t blown or that the circuit breaker hasn’t tripped to the off position. Replace the fuse or reset the breaker if this is the case, and then try to resume normal operation. Remember also that blown fuses and tripped breakers signify an electrical overload. If it happens again, be sure to call an HVAC specialist for help.
Step 4: Check the Furnace and Filter
Next, if you still have a broken furnace after following the aforementioned steps, check the furnace and filter for obvious problems. A clogged air filter can have a tremendous impact on the operation of your unit, so this is a great place to start. If the filter looks clean, check the outside of the furnace for anything unusual, such as an odd sight, an odor, or even a strange noise. In the event you hear, smell, or see anything out of the ordinary, turn the furnace off and call for help. (Remember: if you smell natural gas, which has a sulfuric smell like rotting eggs, evacuate your home immediately and call your local fire department and/or gas company once you have left your home safely.)
