Why Is My Furnace in Katy, TX So Loud?

The furnace in your home in Katy, TX should make only two kinds of noises: a slight hum and a temporary popping that results from the expansion of your HVAC ducts. Any other sounds reliably indicate that something is wrong with your furnace. Here is why your furnace may make strange noises and what you can do to quiet it down.

Buzzing

A persistent buzzing noise typically suggests that there’s some kind of mechanical problem with your furnace. Most commonly, it means that something is wrong with its motor, and a professional will need to inspect it, diagnose the problem and fix it.

More simply, it might indicate that the system’s panel door has come loose or that there are loose bolts or screws somewhere. Regular maintenance can take care of such issues.

Whistling

If air moves through your furnace’s filters and courses past some debris that happens to be sitting at an odd angle, the resulting friction may generate whistling noises. Your furnace’s filters will inevitably become dirty over time, so make sure to clean them at least once every 90 days. That and some periodic maintenance will prevent whistling noises from occurring.

Grinding or Scraping

The usual causes of grinding and scraping noises are serious enough to warrant a call for professional repairs. The sound often means that either your furnace’s blower wheel no longer works, or its bearings have worn out. If you hear grinding or scraping, always shut off your furnace until trained technicians arrive to diagnose the problem.

Treat all loud and jarring noises that come from your furnace as cries for help. They nearly always point to some kind of significant trouble that you must take action to solve.
