HVAC MYTHS

The HVAC industry is full of different opinions. Some of these opinions become skewed overtime, and now there are many myths and misconceptions about the HVAC industry. Here you will read that these common HVAC myths are debunked and why.

Myth: Air filters only need changed once a year

Fact: You should change your filter every few months. Not changing your filter regularly causes strain on your HVAC system and causes it to work harder. Regular changing also provides you greater air quality. Check out our blog Filter Fundamentals for the basics in changing out your own filter.

 

Myth: Unused vent registers should be closed to improve efficiency

Fact: Unused vent registers should be open, or cracked. The common misconception that closing a vent in an unused room will improve efficiency is simply not true. The added pressure around the seal can cause strain on your unit. It can also add unnecessary pressure on other vents in the home. The pressure can eventually cause air leaks, requiring expensive repairs and maintenance. The result is a much less energy efficient home.

 

Myth: A bigger HVAC system is always better

Fact: Bigger isn’t always better. In fact, if a system is too big for a space, it won’t be as efficient. There are a number of variables that go into determining the right system for your house, and square footage is one of them. HVAC companies perform a load calculator to determine the appropriate size of equipment needed for your space.

 

Myth: You should cover your AC unit during the winter

Fact: Covering the AC can cause internal damage and rust. AC covers sound like a great idea in theory, but they can damage the unit because of the moisture that gets trapped inside. Covers are also not a great idea because they are a great place for wildlife to nest.

 

Myth: Tankless water heaters don’t have enough water

Fact: Tankless water heaters never run out of hot water. These systems run cold water through a heating system before it leaves your tap, so you have an endless supply. Tank water heaters are more likely to run out of hot water, because once the supply is out, it can take a while to heat up a new tank.

 

Thermostat Location

Myth: Thermostat location doesn’t matter

Fact: Thermostat location does matter. Temperatures can spike or dip in different areas of the home, so it’s important to put it in a neutral zone. Make sure the thermostat is not across from a window or in direct sunlight to avoid sunlight and temperature fluctuations. Also ensure that the thermostat is not around any heat appliances, as this can raise the temperature as well.
