Heating SystemsIs It Bad To Run My Heating System 24/7?


When cold months hit the Seattle area, your furnace needs to be ready to go. An annual inspection and tune-up is always a good idea heading into the winter because once the temperatures drop, your heating system needs to be prepared for the long haul. MM Comfort Systems is a trusted name in heating and cooling, and we serve homeowners in Seattle, Bellevue and Tacoma, Washington. Once the furnace season is in full swing, how often should you run your heating system? You can set your thermostat to “On” so that your fan always runs, even when your furnace is not on. However, many homeowners don’t like the idea of their systems running 24/7. Their concerns might be a little misguided, though. Let’s get to the truth about a few fairly common questions related to running a heating system continuously.

Won’t That Make My Energy Costs Go Up?

This rationale makes sense. Most homeowners think that the more their heating system runs, the more energy they’re using, which will reflect in their monthly bill. Today’s heating systems are quite efficient, so running the fan continuously does not expend excessive energy. Also, running your system 24/7 could save you money in the long run. Circulating the air in your home can eliminate random cold spots, which can trigger your furnace to kick on.

Does That Mean a Lot of Wear and Tear on My Furnace and Fan?

You don’t have to worry about running your heating system continuously — it’s designed for that very purpose. Don’t be worried about wearing out the components of your system or even risking premature breakdowns, either.

Does It Even Make a Difference?

Running your heating system nonstop comes with a variety of benefits. Not only can you more evenly heat your home — especially two-story homes — but circulating more air can enhance your air quality, as more of it passes through your home’s air filter.
