7 Common HVAC Myths Debunked

7 Common HVAC Myths Debunked

July 20, 2021 | Cooling, Heating

When it comes to increasing both the energy efficiency and the life expectancy of your HVAC system, don’t buy into the common myths surrounding your home’s care.

We’re debunking seven of the most common HVAC myths:

1. Increasing or decreasing your thermostat temperature will help to heat or cool your home faster
No matter how much you increase or decrease the set temperature on your thermostat, it will take the same amount of time to heal or cool off your home. Dramatically increasing or decreasing your thermostat throughout the day will only cause an increase in your energy consumption and ultimately your utility bills.

2. Ceiling fans are only necessary in warmer weather, not winter
Ceiling fans can be helpful to use throughout the year, not just in warmer months. Switching the direction of the fan blades between seasons will adjust whether warmer air is being pushed up or down in your room, helping with the air flow and the overall comfortability of your room.

3. Closing vents in underutilized rooms will increase energy efficiency
Closing vents in rooms will increase the air pressure in your ducts and can cause leaks at the vent seams. It has a very little impact on overall energy efficiency, but can lead to increased wear and tear on your system. It’s better to leave vents open in every room, regardless of how often that room is utilized.

4. Seasonal maintenance isn’t necessary
Your HVAC system performs at its best with routine cleanings and tune-ups. When your equipment is properly cleaned, it typically lengthens the life of your equipment and ensures it’s running at optimal energy efficiency. Routine maintenance also allows for any early signs of damage to be detected prior to an interruption in system performance. In addition, skipping professionally-conducted seasonal maintenance checks can void your manufacturer warranty. Learn more about HVAC seasonal maintenance packages here.

5. It’s best to cover the outdoor unit for winter
Covering your outdoor unit for the winter can trap in moisture, leading to early corrosion of parts. The best method for winterizing your unit is to place a board over the fan.

6. The location of the thermostat doesn’t make a difference
Placing your thermostat near vents, in direct sunlight or near a drafty window can cause the unit to run longer or shorter than necessary to ensure your home’s comfort. This can increase your monthly utility bills while shortening the lifespan of your unit.

7. The size of the unit doesn’t matter
A system that is too large or too small for your property will cause the unit to cycle on and off throughout the day, increasing your overall energy consumption and causing excess wear and tear to the equipment. Ensuring your equipment is the right size for your home is key to ensuring your comfort, lowering your energy consumption and increasing the lifespan of your HVAC system.
