The Truth Behind the Most Persistent HVAC Myths

An efficient unit means not only better comfort but also higher energy savings. If you have old equipment, the time is ripe for a replacement. Your HVAC should adhere to the latest requirements set by the U.S. government.

However, before you pull the trigger on your purchase, it’s imperative to debunk stubborn myths about HVAC systems. Any experienced heating, ventilation, and air conditioning business will say that these misconceptions should be debunked:

Bigger Always Means Better

The oldest misperception of them all: bigger units outperform smaller ones at all times. While bigger devices are powerful, it doesn’t necessarily mean that they run efficiently. Buying oversized heating equipment can backfire.

If your unit is too large for your space, it will work under “short cycles,” and turn on and off more frequently. Short cycling can shorten its service life. Rather than choosing the one with the highest capacity, measure your home’s square footage to pick an adequately sized unit.

All Heating Units Use Only One Distribution System

Furnaces, boilers, and heat pumps are inherently different, and they’re not always compatible with a similar output distributor. For instance, forced-air systems rely on ducts, while old-fashioned, steam radiant heating equipment depends on radiators. Without knowing what unit works with which distribution system, you might waste a lot of time shopping around for incorrect replacement products.

Improperly Sealed Ductwork Is Just an Energy Drain

Leaky ducts do more than just wasting energy. They can also affect your home’s indoor air quality because they can circulate pollutants from your dusty attic or musty crawlspace. They pose a threat to your family’s safety; they can cause harmful backdrafts, like carbon monoxide, to get into living spaces instead of going outside. If you have existing ductwork, make sure that it has no holes or gaps before buying a new furnace or heat pump.
