Why is my HVAC making noise?

It’s normal for your comfort equipment to make a little noise as it runs. There are several factors that impact its sound level, like age and insulation.

However, hearing weird or loud noises might mean a future issue with your machine. If you fail to service it, there can be serious (and expensive) consequences down the road.

Here are some of the AC noises and furnace noises we regularly experience in San Antonio and what they can mean. If you’re hearing any of these sounds, contact a professional as soon as possible. Aramendia Plumbing, Heating and Air will determine what’s happening with your unit and what needs to be done to fix it.

Systems that make too much sound raises sound pollution. While noise might not necessarily affect energy efficiency, it could affect comfort in your home.

HVAC units manufactured now are quieter than previous models. However, it’s good to look for sound levels for your new air conditioner or heat pump, particularly if it’s located near your bedroom or living room.
