Furnaces can last 15 to 20 years or more with proper maintenance. To extend the life of your furnace, it helps to keep the following furnace myths and misconceptions in mind.
Close Vents if You Want Less Heat
Myth: It would seem like common sense to do this. However, closing vents just makes your furnace work harder. If you notice that some of your rooms are hotter than others, it means your furnace needs to be inspected. Uneven heating could be caused by clogged vents or issues with your thermostat.
Keep Your Furnace as Long as It’s Still Working
Myth: A functioning furnace isn’t necessarily one that’s efficient. If your furnace has been around for 20 years or more, it’s time to consider upgrading to a new one. Today’s furnaces are more efficient than ones made a few decades ago. A new furnace installation requires more of an investment up-front, although it will save you money in the long run. Signs you need a new furnace include:
- Inconsistent heating
- Higher energy bills
- Frequent repairs
- Unreliable operation
Focus On Energy Efficiency When Purchasing a New Furnace
Myth: Today’s furnaces are more efficient. Home furnaces and HVAC systems that are moderately efficient have an 80% to 83% annual fuel utilization efficiency (AFUE) rating. High-efficiency furnaces can deliver almost 99% AFUE. However, you won’t get the optimal efficiency if your home isn’t energy efficient as well. You can attain this goal by:
- Looking for drafts around doors and windows
- Cleaning vents
- Having your ductwork checked for leaks
It’s Normal to Have Cold Feet in the Winter
Myth: If your feet are regularly cold indoors, it could mean your home lacks sufficient insulation. This means your furnace works harder than it has to keep your home warm. Heat naturally rises, but even so, a well-insulated home should be warm from ceiling to floor. If your windows or doors feel cold to the touch or drafty, consider replacing or insulating them.
It’s OK Not to Maintain Your Furnace Every Year
Myth: Even if your furnace is still working just fine by the time it gets to be a year or two old, it’s still important to keep it well-maintained. There could be small, underlying problems that aren’t apparent until a professional makes an inspection. Neglecting regular maintenance could also invalidate your warranty.
