Why Low Air Flow in Your Furnace is a Big Problem

You may have noticed that the air isn’t flowing through your ducts as quickly as you’re accustomed to when you turn on your heater. It may not seem like a big deal: the heater is still running after all. But in point of fact, low air flow in your furnace system is a big problem. The good news is that there are services that can correct it here in San Antonio, TX, but the moment to detect the issue, you need to turn off your furnace and call them right away. Here’s why low air flow is a problem.

What Causes It

Generally speaking, one of two things will cause low air flow. Either the air passages themselves are blocked or the fan blowing it isn’t sufficiently powerful  to move the air. If it’s the fan, you’re usually looking at an issue with the fan motor or the electrical components helping to power it. it might also be a bent fan or a snapped fan belt. If it’s a blockage, it could be anything from a filter in need of changing to a block or a breach in the ducts. (If it’s the latter, you can spot it by seeing if the air flow is limited to one vent outlet.)

Why It’s a Problem

Low air flow means that your home isn’t being heated the way it’s supposed to, which means your heater will have to work harder to do its job. That means higher monthly heating bills and an increased possibility of a breakdown elsewhere in the system. Indeed, the chances of a breakdown are increased regardless, since the hot air isn’t moving out of your furnace and individual components may overheat.
