The HVAC industry is constantly evolving to better fit the needs of consumers. With all these continual improvements being made to the technology, it’s only natural for there to be some misconceptions about the industry and the HVAC appliances in your home. Here are just a few of the myths surrounding HVAC systems.

Myth 1: Air filters only need changing once a year.

There are a variety of factors that determine how often your filter should actually be changed, but most HVAC systems’ filters need to be changed every one to three months, according to It’s best to check your air filters regularly for accumulation of dirt and debris. Dirty filters can decrease the efficiency of the appliance and leave you with higher heating and cooling bills.

Myth 2: The more you move the thermostat up or down, the faster it will adjust the temperature.

Moving your thermostat up or down by several degrees at a time will not affect the speed of temperature change. The thermostat works as a regulator that tells your system when to turn on and off based on the number you set it to. It will not work faster if the thermostat is raised or lowered by, say, ten degrees as opposed to three degrees.

Myth 3: The location of the thermostat does not affect its performance.

Thermostats read the temperature around the proximity where they’re installed. If it’s located near another temperature element such as a hot sunny window, it may overcompensate and cool the area down more than necessary. This not only increases your utility bills, but it can create a less-than-comfortable environment for residents.
Myth 4: You can save money by closing off the vents in unoccupied or unused rooms.

While this is a nice theory, it’s simply not true. Closing vents actually throws off the balance of the entire system, and it may eventually lead to other issues such as leaks that are caused by buildup of pressure in the duct work.

Ultimately, the best way to optimize performance and lifespan of your HVAC system is to check it regularly and keep up with routine maintenance procedures. For more information about HVAC systems, maintenance, and repairs, contact Hager Fox today.
