white question mark on a blue background iconWhen it comes to finding information, the internet has made our lives much more convenient than they were even thirty years ago. However, with the abundance of information out there for us to consume, some of it can be wrong. You can type in a question about any appliance in your home and get bombarded with tips and tricks, and chances are, you’re going to click on one of the first results that come up. But unfortunately, just because information is easy to reach doesn’t mean it’s true—and this is how myths start.

There are a few myths about Austin, TX HVAC systems and services out there that you should be aware of. Believing these myths can hurt your HVAC systems, and subsequently hurt your wallet. Keep reading to learn more.

Myth #1: The Air Filter Only Needs to Be Changed During Maintenance

The air filter that comes standard with your HVAC systems is an essential part of protecting the interior components of those systems from becoming dirty and therefore damaged. The air filter is actually not there to improve indoor air quality, however a clogged air filter could certainly have a negative impact on air quality.

This air filter needs to be changed every 1 to 3 months. Otherwise, your HVAC system will suffer a drop in efficiency, which will lead to other serious problems like short-cycling and a frozen evaporator coil. Cheaper filters will need to be changed more often than their more expensive counterparts, and you also may need to change yours more if you have significant contaminants in your home, such as pet dander and/or cigarette smoke.

Myth #2: Closing Vents in Unused Rooms Will Save Energy

We understand why you might believe this. If there’s no cooled or heated air making its way into any given room, it must mean that it’s less work for your HVAC system. However, this is not the case. Not only will closing room vents not save money, but it can actually damage your ventilation system.

The blower fan within your HVAC system won’t work any less when you have vents closed. However, it will increase pressure with your air ducts. This increase in pressure will lead to the blower fan running for longer, which wastes energy rather than saving it. Plus, the pressure spike can cause air leaks in your ducts, which could leave you needing ductwork replacement.

Myth #3: You Do Not Need Routine HVAC Maintenance

This may be one of the most dangerous myths there is regarding HVAC systems. Maintenance is a necessary service to keep your system in good operating condition, with the longest lifespan possible. It prevents potentially unnecessary repairs and breakdowns, and keeps your HVAC systems safe. This is particularly important if you use a gas-powered heater.
