We’re always surprised that in a time when we can find the answers to almost any question with the press of a button, people continue to spread misinformation about even the most straight forward topics. There are several common home furnace myths that we want to debunk with this guide because not only are they untrue, but they can actually damage your heating system.
Myth #1: Closing the vents in low traffic rooms will reduce your monthly bills.
This home furnace myth, like many, has no evidence to support it. Closing certain vents to direct more air to the higher traffic areas of your home with one or two vents may make the house more comfortable. However, closing too many registers will trap excessive heat in your plenum (above the furnace) which will signal your furnace to shut off prematurely as a safety precaution due to high temperatures. In some cases, this may actually increase your monthly bills rather than reduce them.
Myth #2: The bigger the furnace the better.
Although this home furnace myth is supported by some logic, albeit misguided, it’s false and can lead to high energy bills and frequent repairs. A unit that is too large for your home will cycle on and off more frequently because the large blasts of heat will inaccurately trigger your thermostat. This constant cycling is extremely hard on the furnace’s internal mechanism and will drastically reduce its lifespan and cause excessive wear and tear on its components. It also results in the home feeling cold as the furnace doesn’t run long enough to even disperse the air.
Myth #3: You can heat your home faster by raising the thermostat.
It would be excellent if this home furnace myth was true, but unfortunately, it isn’t, and it will likely just result in hefty energy bills. Furnaces are designed to deliver heat at a constant rate to create an even temperature throughout your home, instead of short-lived hot spots. Turning the temperature up higher on your thermostat will only cause your furnace to stay on longer until it achieves the set temperature, which will waste energy and likely leave you feeling too hot once it reaches the heightened temperature.
Myth #4: You only need to book furnace maintenance if you have a problem.
This is one of the most common home furnace myths, but the “if it ain’t broke don’t fix it” mentality is misguided in this case. For starters, most manufacturer’s warranties require you to get annual maintenance to keep them valid, and they also won’t cover defects resulting from misuse or negligence. Licensed technicians can also identify small problems before they lead to large, costly malfunctions or full-blown breakdowns.
