What HVAC Misconceptions Exist for Customers Today?

common HVAC misconceptionsEvery once in a while, it’s a good time to debunk certain HVAC misconceptions that pop up frequently. These cooling and heating equivalents of urban legends somehow manage to persist, probably because they sound like they ought to be true. However, the facts are what they are. Here are some common HVAC misconceptions that just keep coming back, along with the actual truth of the matters:

  • Save energy and lower monthly bills by shutting off your AC while you’re gone during the day.  Sounds reasonable, but the research doesn’t support it. Cooling off a stuffy, overheated house after a long summer day consumes more energy than setting the thermostat to a moderate temperature and letting the air conditioner keep the house cool while you’re away.
  • Close HVAC supply air vents in some rooms to reduce cooling and heating costs. A good idea — if only it was true. Actually, your AC or furnace has no idea whether you’ve closed some vents or not. Therefore, it just keeps on keeping on, delivering the same rated BTU capacity as long as the system’s running. For balanced airflow and temperature control, keep all vents in all rooms open at all times.
  • Change the air filter every other month year-round. That’s right, but only half the time. The recommended schedule is to change the filter every month during summer cooling season and every other month during heating season. A central air conditioner actually runs substantially more total hours per day in summer than an average furnace does during the winter. This warrants monthly changes for the AC while changing the furnace filter every other month is generally adequate.
  • You can cool a hot house quickly by setting the AC thermostat as low as it will go. Or, maybe you’ll just imagine it’s cooler. The fact is, your air conditioner only produces the same fixed volume of cool air at any given time, no matter how far down you push the thermostat setting.
