It’s November in Bel Air—cool mornings, warm afternoons, and suddenly your heater is running like it’s the dead of winter. If your HVAC seems to never stop kicking on, you’re not imagining it. While it might seem like your system is just doing its job, this constant running can raise energy bills, create wear and tear, and make your home less comfortable.
Let’s explore why your heater might be overworking and what you can do to regain control.
Why Your Heater Keeps Running
- Seasonal Temperature Swings – Early fall often brings dramatic swings in temperature. Your thermostat may be set to maintain a constant temperature, so it kicks on whenever the house dips a few degrees—even briefly.
- Thermostat Placement or Calibration Issues – If your thermostat is near a window, heat vent, or sunny spot, it may misread the actual room temperature, causing your system to run more than necessary. A miscalibrated thermostat can have the same effect.
- Dirty Air Filters – When airflow is restricted by a clogged filter, your HVAC must run longer to heat your home. This is one of the simplest issues to fix but often gets overlooked.
- Duct or Insulation Problems – If warm air escapes through leaky ducts or poorly insulated walls, your system works overtime to maintain comfort.
- Fan Set to “On” – If the fan setting is switched to “On” instead of “Auto,” it can keep circulating air even after the heater has reached the set temperature.
Quick Fixes You Can Try First
Before calling in a pro, try these quick steps:
- Check Thermostat Settings: Make sure it’s set to your preferred temperature and the fan is on “Auto.”
- Replace or Clean Air Filters: A clean filter restores proper airflow and can reduce heater runtime.
- Inspect Thermostat Placement: Ensure it’s away from windows, vents, and heat sources.
- Check Vents: Make sure no furniture, curtains, or rugs are blocking airflow.
When to Call the Experts
If your heater is still running non-stop after these checks, it’s time to call a professional. Ignoring the problem can increase your energy bills, cause unnecessary wear on your system, and even lead to costly repairs down the road.
