Common Misconceptions About Your HVAC System

Feb 5, 2020

Day and night, season after season, your home’s HVAC system is constantly working to make sure you are cozy — whether you find yourself amid a blazing hot summer afternoon or in the throes of a long and cold winter night. And while this is true, many misconceptions are floating around out there about HVAC systems, how they work, and so-called user “tricks” to save money and energy. To raise awareness about a few of these more common myths, we at Grove City Heating & Air composed the following to debunk them.


Myths About Your HVAC System


Cranking The Thermostat Up Or Down To The Max Will Cool Or Warm Your Home Faster

This myth is pretty widespread. Thermostats communicate data to your units that command them to switch on and off to maintain the temperature level you desire in your home. Turning it up or down all the way does not cool off or warm up your residence any quicker. That’s not how it works.


If You Close Off The Vents In Rooms You Aren’t Using It Will Enhance Energy Efficiency

This misconception is a common one. Closing air vents in unoccupied rooms can increase the flow of air, but it also places extra pressure on the ducts. This additional pressure can create air leakages around the seams of the vents. If you find your residence has areas that are hot and cold, we encourage you to consider a zoning system.


Air Filters Do Not Need To Be Changed As Frequently As They Say. A Filter Can Last You A Whole Year

This misconception can wreak havoc on your system. We strongly advise you don’t take a chance trying this out. Most HVAC pros suggest changing your air filter often, like once every two months, and even once a month during the winter. If you have pets in your home, you should definitely abide by this rule. Nevertheless, if you want to spare yourself the hassle of replacing it so often, you might consider an in-home air purifier, which could help.


You Don’t Need Check-ups Every Year

This is among the most costly of misconceptions. Because your home’s HVAC system is an extremely valuable and intricate machine, it needs annual tune-ups like that of a car. Today’s HVAC systems have all sorts of moving parts that should be inspected, oiled, lubricated, cleaned, and possibly even replaced regularly. During these check-ups, technicians also perform important calculations to guarantee your system is functioning at its best. We firmly suggest that you have a professional tune-up your AC and furnace annually to make sure it runs efficiently for a long time to come. Annual tune-ups can save you from having to make expensive repairs in seasons to come. Just remember, it always pays to be proactive rather than reactive when it comes to your HVAC system.


The Bigger The System, The Better

This is a misconception that’s easy for people to believe. After all, isn’t bigger better? The answer is no. A furnace or AC that’s too big for the size of your house will cycle on and off excessively. This short cycling will raise your bill in addition to reducing the lifespan of your system. For this reason and many others, furnace and AC installation is not a Do-It-Yourself job. When the time to replace your home’s unit finally arrives, having one of our experienced technicians do the job is a must. We can measure each room in your house and propose a specific system that has the correct specs you need for the best energy-efficiency possible.
