If you go to turn on your furnace and it’s not blowing hot air, it could be a couple of easy fixes.

Number one is look at the thermostat. I know it sounds silly, but is the heater even on? A lot of times, between the summer months and the winter months, people just turn their fan on, instead of auto. At that point, it will just blow regular air. It won’t blow hot air. So I would say, step number one: look at your thermostat. Is it set on the right setting?

One of the most common issues is airflow. If you haven’t changed the filter, it could be really clogged. Again, a lot of times, our furnaces just sit there between summer and winter. Out of sight, out of mind.

Furnaces are actually really smart. If it’s clogged and can’t breathe, it’s suffocating itself, and will actually shut down to protect you and your family. So number two, check the filter.

Then if all that checks out, it might be a good time to get a tune-up from the On Time Experts. It’s usually either electronics or pressure switches, a lot of technical mumbo jumbo that we deal with. But there are a lot of safety devices that prevent that furnace from actually firing up for you.

During our winter tune-ups, we check all those safeties, make sure that your filters are nice and clean, and the batteries have been replaced in your thermostat. The best idea is to get us out before the season starts, so we’ll have you up and ready when the first cold night hits. Call us any time at 469-336-3435.
