HVAC - Debunked

If you look around, you’ll find no shortage of information on how to maintain your HVAC system. Unfortunately, however, it’s not always accurate. That’s why we created this list of some of the most common HVAC myths. By understanding the truth behind them, you can make smart decisions that increase the lifespan of your HVAC system while protecting yourself and your family for years to come.

Myth #1: I Only Have to Change My Filter Once a Year

For some reason, many homeowners have been led to believe that changing their filter is an annual job. Since a dirty air filter can clog your HVAC system and reduce airflow, it’s important to change it every three months or so. This way you can get rid of dust, grime, debris, and other particles that can build up each day. If you have pets, children, and/or allergies, you may want to change it more frequently.

Myth #2: The Bigger the HVAC System, The Better

You may be surprised to learn that in some cases, a bigger HVAC system can be worse. It might short-cycle (shut on and off prematurely) and damage your system in the long run. With a bigger system, you may also have to pay for power that you don't necessarily need. A smaller system may not only last longer but also save you a great deal of money down the road.

Myth #3: Routine Maintenance Isn’t Necessary

When it comes to HVAC systems, some homeowners have a “if it ain’t broke, don't fix it” mentality. Just like your car, your HVAC system needs a tune-up every year to keep it in good working order. It’s in your best interest to hire an HVAC technician to thoroughly examine it and resolve any issues before they become more serious.

Myth #4: I Can Reduce My Energy Bill with an Energy-Efficient Unit

These days, there are many energy-efficient HVAC systems on the market. While they can be a sound investment, they won’t magically lower your heating and cooling costs on their own. You’ll need to ensure good insulation and window seals that are free of leaks. Maintaining your system will be important as well.

Myth #5: I Need to Cover My Unit in the Winter

HVAC systems are specifically designed to be outside, meaning they can withstand rain, snow, and temperature fluctuates. Therefore, covering your unit in the winter months may actually do more harm than good.

Rodents may make their way in and cause issues such as chewed wires and mold. In the event you do need to cover your unit because you have a tree directly above it, for example, simply cover the top with something like a large wooden board.

Myth #6: The Location of Your Thermostat Doesn’t Matter

Thermostats inform your heat and air of when to turn on and off. Since your thermostat only knows the temperature of its surrounding areas, placing it improperly can affect your HVAC system’s accuracy and efficiency. The ideal spot for your thermostat is on an interior wall, away from direct sunlight, windows and doors, air vents, and hallways.
