When it comes to maintaining your heating and cooling system, many unverified tips and tricks are frequently passed around. Using inaccurate information could drive up your energy bills and harm the system, so learn more about what's true and false below.

Common HVAC Misconceptions

1. Bigger Systems Are Always Better

People tend to think that the bigger an appliance, the more powerful and efficient it is. However, oversized systems will cost you more in the long run. A system that's too large for your home will continuously cycle on and off and won't run long enough to dehumidify the space properly. Your system's actual size should depend on your climate zone, the number of household occupants, and the layout and square footage of your home.

2. You Should Cover Outdoor Units in the Winter

While you may want to protect outdoor units from harsh winter weather, covering them can cause various problems. A cover will trap moisture, encouraging mold growth and corrosion. Rodents might also take shelter underneath the cover to escape the chill and chew the wires in your unit. In reality, outdoor units are built to withstand winter conditions and don't typically need protection.

3. Setting the Thermostat Lower Cools the Home Faster

There's a pervasive myth that if you want the house to cool down faster, you should set the thermostat lower than your desired temperature. However, the thermostat will only signal your system to run until it reaches the correct temperature, then turn off. As a result, setting your thermostat lower will only make it run longer, not faster.

4. You Only Need a Professional for Repairs

Many homeowners only call HVAC contractors when something's broken. However, heating and cooling systems see constant use. You don't want to wait until a severe problem occurs to get help, because the repairs could be expensive and you might even need a new system. Regular maintenance will ensure everything is functioning smoothly and your system will last through the coming season.

5. Closing Vents or Doors Saves Money

Nobody wants to pay to heat or cool rooms they don't use. However, closing vents and doors won't save you any money. Shutting off these paths interrupts your HVAC system's airflow, which will make the unit work harder to distribute air in other areas. Cutting off airflow can also increase pressure in your ducts and cause leaks at the vent seams.
