3 Reasons Your Furnace is Prematurely Shutting Down

At this point in the season, you may or may not have switched your HVAC over to heat. Our temperatures as of late have been rather pleasant. In fact, for many of our customers, we're finding that they simply turned everything off and opened the windows. However, the time is finally coming for cooler weather. Soon enough, you'll turn on the heat for winter so you can stay warm and cozy.

The last thing you want on a cold day is for your furnace to shut off. This season is full of celebrations. From Halloween to Thanksgiving to Christmas, if the furnace shuts down over the next few weeks, we guarantee it'll be an inconvenience.

Your furnace is a piece of mechanical equipment. Over time, parts wear down, and the opportunity for things to go wrong increases. BUT, there are several things you can do to avoid premature shut-down. With that in mind, today we'll discuss 3 reasons your furnace is prematurely shutting down and how you can avoid a furnace shutdown from happening.

1.  You forgot to change your air filter! 

If there's one thing that you can do to avoid a premature furnace shutdown (among many other HVAC problems), it's to replace your air filters on a regular basis. However, if your furnace has already shut down prematurely, it's quite possible you've forgotten.

Typically, your air filters should be replaced every 1 to 3 months. If you have a busy household, you should plan to replace your air filters even more frequently. We actually just replaced all of our air filters around our home and found that the air filters in the bedroom and living room were way dirtier than other rooms in the house.

Whether you mark your calendar or you just remember to change your air filters at the start of each season, remember to change your air filters on a regular basis to prevent a furnace shutdown. If you're not convinced that you should change them this regularly, pull one out and take a look. Can you see through it? Is it filled with dust? If it is, just imagine how hard your furnace is working.

2. You closed your registers and vents!

Have you ever visited an older relative and played hide and seek in their home? Did you find that some of their rooms were closed off? We remember our grandparents' house had had one room that was full of old furniture and boxes. It smelled of mothballs and was noticeably cooler than the rest of the house. If we didn't know any better, we might think that the room contained ghosts or something.

Maybe you have a similar situation going on in your home. There's a long-standing myth out there that if you close the registers and vents in a room that you'll somehow save money - the thinking being that the air would be redirected to other areas of the house. However, closing your vents and registers will actually increase your energy bill and could cause a premature furnace shutdown.

When you close your registers and vents, your furnace can't operate the way it's supposed to. Pressure will build inside your air ducts and put a strain on the blower system. While you might think that by shutting a room down that you are creating a more comfortable space, you're causing unnecessary damage that can be easily prevented.

3. You didn't schedule a maintenance visit at the start of the season

Finally, if you didn't schedule a maintenance check at the start of the season, it's quite possible that you have an unexpected and premature furnace shutdown. Sure, your home is still young. Your HVAC unit won't likely have an issue this year, but what if it did? Couldn't it have been prevented?

As a homeowner, we fully realize that your time and energy are going to go to the areas of your home with the greatest demands. If a system is working, why mess with it, right? However, having an annual maintenance visit can keep your system operating the way it should without delay. Your HVAC technician can make sure that everything is working the way it should, catch small problems, and fix them before they become even bigger (and more expensive) problems. Regularly scheduled maintenance visits will save you money over time and we highly encourage them!
