4 HVAC Myths

HVAC MythsWe work with a lot of great people, but sometimes they have the wrong idea when it comes to their HVAC system.  Here are some common myths we hear and the right answer.

Duct Tape is Good for Sealing Ducts

Unfortunately, duct tape doesn’t really stay sticky for that long.  After a few years or less, it can lose it’s adhesion.  If you are going to seal your ducts, use a metal-foil tape or air-duct mastic.  Additionally, you can have a professional take a look at your ducts to seal them or see if replacing them might be a better option.

The Lower you Set your Thermostat, the Faster your House will Cool

Your AC unit runs until it hits the right temperature.  Setting it extra cool won’t get your home any closer to it’s goal temperature than if you set it at the goal temperature to begin with.

You Shouldn’t Adjust the Thermostat when you Leave the Home

Many people think that if you turn the temperature way up while you are gone, that when you turn it back on, it uses more energy to cool the house back down then to maintain the temperature the entire time.  There is a bit of truth in this, but in most cases, this isn’t true.  It really depends on how much you are adjusting the temperature, how hot it is outside, and how many times a day you are turning the AC completely off and turning it back on.  It definitely saves you money to adjust it down a few degrees when you are out of the house.  For example, if you normally have it at 75, but are gone at work every day from 8-5.  Program it to increase to 82-85 degrees while you are gone.  Then, have it go back down to your preferred temperature a few minutes before you get home.  That way, you never feel the temperature difference, but save money at the same time.

Closing Vents can Save you Money

It’s common for people to think that if they close vents, it will save them money because they are using less air.  Unfortunately, this is not true.  If your HVAC unit is on, it’s blowing the same amount of air.  Additionally, closing vents can actually cause damage.  If you close too many vents, it can cause back-pressure on the unit, which can cause it to burn out.
