Top 4 Things to Know About Your Furnace

When it comes to your furnace, you want it to be out of sight and out of mind. But knowing the basics of how it works could actually help save you time and money down the road. That’s where ComfortAire Heating Cooling can help. Our experts are sharing their top four things you should know about your heating system. Find them below, then call us at 715-325-3969 in Wisconsin Rapids or 715-342-0911 in Stevens Point for service.

1. A Typical Furnace Lasts About 15 – 20 Years

You should be able to get two decades out of your furnace if you take care of it. However, that lifespan also depends on the wear and tear it’s taken over the years. We love hearing stories of Bryant® units lasting longer, but the older your furnace gets, the less efficient it becomes—even with routine maintenance. Once yours hits this range, it’s time to consider a replacement.

2. There Are Four Main Types of Furnaces

Because of their efficiency, stability, and affordability, natural gas furnaces are the most popular type in both Wisconsin and the U.S. Electric furnaces are generally cheaper for the initial system, but the electricity needed to operate it is more expensive than gas. Oil or propane furnaces are less efficient than modern natural gas systems, store fuel in tanks, and have to be periodically refilled.

3. Air Filters Should Be Regularly Changed

Air filters do the dirty work of capturing dirt and other debris as they circulate through your home. If you have a standard one-inch filter, replace it every one to three months—or more often if you have pets or smokers in the house. High-efficiency filters can be changed less often. Swap them out once every six to 12 months. Not only does this ensure the best air quality, but it also helps your HVAC systems run more smoothly.

4. Annual Maintenance Is Usually Required

No matter the age of your furnace, ComfortAire always recommends getting a Clean & Check every year. It’s one of the easiest and most cost-effective ways to get the most value out of your unit. But newer models that are under warranty often require a qualified technician to inspect and perform routine maintenance. That way if something were to happen and you needed repair, your warranty is valid. Otherwise, you’ll likely be paying for it out of pocket.
