Change Your Filter: The First Thing on Your Fall Furnace Maintenance ChecklistAs I’ve discussed quite a bit in the past, a clean filter is an HVAC MVP, regardless of the season. So, when it comes to prepping your furnace for winter, my recommendation is to start there. Here are just a few of the many problems that can occur if you don’t have a clean filter:
- Air flow reduction: If you haven’t change your filter in a while, it’s at risk of getting clogged with debris. When that happens, the air just can’t get through, meaning that the flow of warm air coming out of your vents will ultimately be reduced, leaving your home uncomfortably cold.
- Higher energy bills: Another thing that happens when your filter is old and clogged is that your furnace will run longer than usual because enough warm air won’t be getting through to lower the temperature on your thermostat. This can result in higher than normal monthly electric bills. I haven’t met a homeowner yet who’s okay with that.
- Dust and other allergens get into your home: As I’ve talked about in the past, a clogged or incorrectly-sized filter can mean dust is being spread by your HVAC system. Allergens like pet dander or mold can scatter throughout your home from room to room, ensuring your family is breathing them in.
Run Your Furnace to Test It, a Fall Furnace Maintenance Guide MustDon’t wait until the cold weather is actually upon us to run your furnace for the first time. Chances are you could discover you have a serious problem when you really need your furnace the most. My advice is to pick a somewhat chilly day as the weather starts to turn a bit to test your furnace, when you still have time to get any issues taken care of before the real chilly weather shows up. Here are some things I advise homeowners to look for:
- Short cycling: Short cycling is when your furnace runs for a short period of time (let’s say three minutes or less) before shutting off. This is a serious problem because it means your home is not being heated properly. It also means your energy bill is liable to be high; a furnace consumes more energy when it turns on and off over and over again instead of running smoothly as needed. Short cycling often indicates problems with the thermostat or a heat exchanger that’s having an issue that causes it to overheat. Either way, it’s time to call an HVAC pro to have it checked out.
- Odd noises: Unusual sounds, like a rumble, pop, or bang when your furnace is running is another problem I’ve talked about in the past. They are all sounds you want an HVAC tech to address because they can indicate a broad range of issues, from a loose blower wheel to unbalanced ductwork. These problems generally start with an odd noise before turning into a full on failure, potentially shutting the whole system down. Again, best to get this one taken care of early.
- Irregular flames: Open your furnace up and look at the flame in there. Is it uneven or leaning toward the back of the unit? If so, it’s time to call in a pro. These are signs of problems that include dirty burners or a cracked heat exchanger, neither of which is something you should try to tackle yourself.
An Annual HVAC Check-Up: Let the Experts Guide Your Fall Furnace MaintenanceThis last step is the most important. Simply put, you’re doing your furnace a disservice if you don’t get it a tune up each and every year. I’m sure you ran it quite a bit last winter, which was one of our coldest and rainiest in years. Well, your furnace is kind of like driving a car. If you were about to go on a long road trip, you’d probably have a mechanic change the oil, service the breaks, and make sure everything is in running order either before you left or when you got home.
Don’t forget, your furnace is a complex mechanical system, just like your car’s engine. You want to get it a tune up before putting a significant amount of miles on it.Don’t forget, your furnace is a complex mechanical system, just like your car’s engine. You want to get it a tune up before putting a significant amount of miles on it. If you don’t, it’ll be far more likely to break down and, like your car, you definitely don’t want it to fail when you’re in the middle of using it. Preventative maintenance by an experienced HVAC tech is a key to a healthy furnace this winter. So there you have it, a fall furnace maintenance guide, a checklist that, when followed carefully, will squash most minor problems before they turn major. I’m sure you’re a fan of saving money so, take it from me, this kind of preventative maintenance is way easier on the wallet than an HVAC crisis during one of the coldest months.
