Why Won’t My Furnace Stop Running?
Is your furnace blowing air without pause? If so, you’re probably feeling a bit concerned. First, your house most likely feels like an oven. On top of that, your utility bill will be considerably higher with your furnace constantly running. Believe it or not, this is a fairly common problem our professionals at AA-AIR CO., see frequently, so you don’t need to worry.
Before calling in a professional, check these three things:
1. Be sure you have the right thermostat setting
Be sure your thermostat is set to a reasonable temperature. ENERGY STAR® recommends keeping it 8 degrees Fahrenheit cooler when you are sleeping during the winter to save on utility costs. If you set your thermostat to ultra-high temperatures, this may cause it to run constantly. Additionally, be sure to set your thermostat to Auto instead of On. The On setting causes the fan run constantly, whether heat is on or not.
2. Check the filter
If you haven’t changed your furnace filter in a while, this could be the source of the problem. Over time, dust and debris clog your filter. This constricts airflow, which means the furnace has to work extra hard to maintain the desired temperature in your Tennessee home. Depending on how clogged the filter is, it may have your unit running nonstop.
If you step 1 and 2 did not work, schedule a repair with us at AA-AIR CO. Here are three potential problems requiring our professional help:
1. Leaky ducts
If your ducts are poorly sealed or blocked, heat isn’t being circulated properly. You’re losing heat and losing money through your utilities at the end of the month. One of our professionals can run perform leak testing or use thermal imaging to determine the extent of the leaks and plan and estimates repairs for your ductwork.
2. On a heat pump
An electrical component called a sequencer could be stuck and causing the unit to continue to run well past the thermostat setpoint.
3. Thermostat malfunction
Your thermostat is the brain of the operation. When it sends the wrong information to your furnace, a number of things can go bad. You could have a broken relay switch, or your thermostat could be producing an inaccurate temperature reading.
