Keeping your home cool and comfortable requires the right HVAC maintenance and service. Homeowners are also encouraged to know the facts about their AC units, as there is a lot of misinformation surrounding these essential appliances. The following are a few of the most common myths and why they should not be believed. 

Don’t Fall for These 4 Common Home Air Conditioning Myths

1. ACs Create Cool Air

Air conditioners do not magically generate cooled air to make your home more comfortable. They actually absorb heat from the air inside your home and move it outside. This process occurs via the evaporator coils and refrigerant, which transfer heat to the outdoor portion of your unit where it is released. 

2. Turning Down the Thermostat Makes Your Home Cooler Faster

Your air conditioner will only cool your home as fast as the blower fan allows. That means your home will cool down at the same pace whether the thermostat is set to 72 or 62 degrees.

Upgrading to a programmable thermostat gives you more control over your home’s comfort since you can set it to switch on at a certain time each day. This ensures your home will be cool by the time you're done with work. 

3. Closing Vents Saves Money on Utility Bills

HVAC maintenanceAC vents should remain open throughout your home, even in rooms that are not being used. Open vents make it easier to maintain a consistent temperature, which is integral in doing away with hot spots. Closing vents does not actually save you money because it has no impact on the power your HVAC equipment is using to cool your home. 

4. Doors & Windows Are the Primary Sources of Air Loss

Without the proper insulation, your AC unit will need to work harder to maintain the same cooling capability. While it’s true that windows and doors are common areas where air escapes the home, there are actually plenty more areas that can contribute to air loss. Faulty air ducts can leak air, as can gaps around roof fixtures, like chimneys and skylights.
