Residential HVAC Maintenance Myths, Busted
Erik Moreno • August 18, 2023

In this digital era, there’s a lot of potential information about HVAC systems that you can come across as a homeowner. Nevertheless, HVAC systems are complex equipment, including multiple components and processes, so not everything you hear about them is true. In this regard, there are many residential HVAC maintenance myths that many homeowners often adhere to. Although some misconceptions aren’t harmful, following others over time can affect your comfort, cost you a lot of money in repairs, and compromise your safety. Below, we burst common residential HVAC maintenance myths.

Myth 1: Closing air vents in empty rooms decreases energy bills

One common myth is that closing air vents in barely used rooms can reduce energy consumption and bills. The truth is that closing the vents can result in increased air pressure in the ducts, making the air vents leak. The leaks will transmit warm and cold air to where they are not needed, leading to the wastage of energy. Leaving all your air vents open, even in empty rooms, is critical to promoting free air flow and preventing leaks caused by excess pressure.

Myth 2: Turning the HVAC off when you leave the house wastes energy

It’s a common myth that leaving your HVAC on when you leave the house instead of switching it off can help save energy. This isn’t true! Turning your HVAC off when you leave the house is more efficient in saving energy. Always switch off your heating and air conditioning system when you are away from home and not using it. Even better, you can install a programmable thermostat on your unit to automatically put it off when no one is home.

Myth 3: You have to change your filter only once a year

As many people purport, you should change an air filter more than once a year. A dirty air filter is notorious for clogging the HVAC, making it difficult to circulate air. This can result in reduced efficiency and increased wear and tear. Generally, you should replace the air filter every few months or whenever it gets clogged with dirt, dust, and other debris. Clear air filters lessen pressure off your HVAC, allowing it to operate at peak levels and have a long lifespan.

Myth 4: Cover the outdoor HVAC unit during winter

Many people tend to cover the outdoor HVAC unit during winter. While it may seem like a great thing to do, shielding the equipment can cause more harm than good. The covering can trap moisture in the unit, leading to excessive corrosion and water damage. These effects can adversely affect the structure of your unit and shorten its lifespan. The best thing to do is to place a board over the fan when excess ice or snowfall is expected. Otherwise, you should leave the outdoor unit uncovered.

Myth 5: You don’t need maintenance if the HVAC is not broken

Another common myth many homeowners abide by is that you don’t need to schedule maintenance services for your HVAC if it isn’t experiencing any problems. This is entirely false! As a general rule, you should have your system maintained at least once a year. Routine maintenance is key to ensuring your HVAC operates at peak levels, thus lessening frequent repair needs and lowering energy bills caused by inefficiency. It is also great for identifying and fixing lurking issues before they become problematic.

Myth 6: High thermostat settings will make the HVAC heat or cool your home faster

It’s also common to hear homeowners say that cranking the thermostat makes the interior heat or cool faster. This isn’t entirely true! Pushing your thermostat up or down won’t make it heat or cool your interior spaces quicker. Instead of working faster, your unit will work longer to align with your thermostat settings. Consequently, this will result in increased energy consumption and high energy bills. Set your thermostat correctly depending on your indoor comfort needs for better operations. Ensure the thermostat is in a central room that you use frequently for accurate readings, and don’t put it near vents, windows, and radiators.
