What Should I Do If My HVAC System Is Running Loudly?
Wednesday, September 09, 2015

Here’s a how-to guide for handling drama with your heating and air conditioning unit.

HVAC system

If heating and air conditioning problems disrupt your daily life, it’s time to make some changes. You’re sitting in an otherwise peaceful indoor oasis, and suddenly you notice a consistent annoyance – what is that noise and where is that noise coming from? That’s your heating and air conditioning unit making a cry for help. The next part of that question may be a bit harder to solve.

How to Diagnose Your HVAC Problem

The first step to solving this issue is to take some notes. What kind of noise are you hearing? Popping, thumping, vibrating, or humming noises could all indicate different issues. Here are a few of the most common types of noisy HVAC patterns:

  • Thumping/Vibrating: This kind of noise can resemble an out-of-whack washing machine or dryer and will probably be very noticeable. A blower wheel is generally the culprit, but it needs to be realigned to eliminate the possibility of damaging other machine parts.
  • Rattling/Squeaking: This is generally an issue with heat pumps when refrigerant flow becomes restricted but can also be attributed to dirty air filters when air has difficulty passing through the material.
  • Metallic Scraping: The blower wheel is most likely responsible for any noise that sounds metallic and this should be handled immediately as it can put the rest of your system at risk.

What are some possible solutions for your noisy HVAC?

Depending on the severity and frequency of the noise, the first step is to shut off your system. This will prevent anything from escalating in the time it takes to get a professional to inspect the system. While many homeowners may not like the idea of paying for a repair, taking action sooner rather than later will probably save money in the long run.
