5 HVAC Myths Busted

True or False?

With all the information out there provided for us, it can be easy to get confused about what the best practices are for your HVAC system. Today, DG Heating & Air Conditioning is putting those common heating and cooling myths to rest!

Closing Vents Saves Energy

There is a common misconception that by closing vents in unused or low traffic rooms, you’re saving energy. In theory, it makes sense! However, closing vents keeps those rooms from cooling down or heating up to the temperature set on your thermostat.

This will confuse your system and make it work harder to get those rooms to temperature, ultimately wasting energy and money.

Ceiling Fans Reduce Temperature

Ceiling fans are a great way to cool down on a hot day. However, did you know that your ceiling fan cannot actually lower the temperature of a room?

Instead, the motion of a ceiling fan creates a cooling sensation on your skin, making it seem like the temperature is lower. We recommend you only keep the ceiling fan on when you are in the room in order to feel its effects. Check out our blog about ceiling fans and energy costs to learn more.

Cooling/Heating Happens Faster If…

Contrary to popular belief, turning your thermostat to an extreme hot or cold temperature will not get your home comfortable faster. The rate at which your HVAC works stays the same no matter the temperature set!

Thermostat Placement Doesn’t Matter

Proper thermostat care begins with installation! If your thermostat is on a wall that sits in direct sunlight for a long period of time during the day, it will affect the sensor and confuse your system. If your thermostat is placed as such, consider moving it to a darker, cooler place.

Routine Maintenance is a Waste of Money

Routine maintenance is a necessary part of your HVAC’s life. During an appointment, your technician will tune-up your unit, clean it, and perform a thorough inspection. This allows them to fix current issues, as well as stop any potential problems in their tracks, saving you from a bigger issue with a bigger price tag down the line!
