Your Furnace—Myth vs. Reality

What’s your favorite myth? A couple of aspirin or Tylenol after a night of partying will cure your hangover? Black cats mean bad luck? There are a lot of them out there, but the ones Builder’s Heating & Air Conditioning are concerned about are the myths surrounding your furnace or other home heating system. Here are a few examples:

  • Using portable space heaters will save money and reduce energy usage.
    • There are rare circumstances where this can be true. If you spend virtually all of your time in one location inside your home AND you shut off your central heating system, then using a space heater in that single location could save money. But we all know that’s not what happens. Most people use a space heater while continuing to run their central heating system. In that case you are only increasing the energy use in your home. And don’t even get us started on the fire dangers posed by space heaters.
  • Closing HVAC vents or registers in unused rooms will save money.
    • It seems to make sense and your mind is telling you, how can that be a myth? Well, your furnace is designed to distribute warmed air evenly throughout your home. When you have something covering your HVAC vents or you close them,  you are creating airflow problems. The result is your system actually has to work harder to keep the house warm.
  • Cranking the thermostat WAY up will warm the house up faster.
    • Sorry, it just doesn’t work that way. The rate of warming is unchanged whether the thermostat is set at the desired temperature, or 10 degrees higher. What happens if you turn it way up, then you forget to turn it down until the house is too warm? All you’re doing is wasting energy.
  • All I have to do to cut heating bills is install a new high-efficiency furnace.
    • This is NOT a myth, but it’s also not the complete truth. Builder’s will be happy to install that new furnace for you, but we want to make sure you receive the full benefits. If you have other problems in the home like leaky ductwork or poor insulation, you will never realize the full-savings of the high-efficiency furnace. That’s why our expert technicians are trained to look at the entire house during the installation process.
  • Duct tape is good for sealing up any leaks in my HVAC ducts.
    • Duct tape is a marvelous product for many things, but despite the name, it’s not really meant for use on heating and cooling ducts. It tends to dry, peel and not stick very well. We recommend calling in a professional from Builder’s to repair leaky ducts, but if you are going to do it yourself, aluminum foil tape or mastic sealant are better choices than duct tape.

There are many other furnace myths out there waiting to be exposed, so make sure you are getting advice from someone you can trust.
