Why is My Furnace so Noisy? – Pt. 1

repair technician When your appliances start to make unusual noises, it’s more than just annoying – it’s a sign of a potentially serious problem. When your furnace is making strange noises, it is usually time to call a professional for heating repair in Conroe, TX. Here is a guide to common furnace noises and their meaning:

Scraping – If you hear scraping or the sound of metal hitting metal, it can be one of three things:

  1. Loose Blower Wheel – When the blower wheel becomes loose it can scrape the housing. If this continues, the wheel can do damage to both itself and the blower wheel housing.
  2. Broken Blower Wheel – If the blower wheel is broken it will vibrate around in the housing, causing scraping, squealing, and banging sounds.
  3. Broken Motor Mount – If the motor mount is broken it causes the blower wheel to rattle against the housing.

Thumping – A thumping noise could be the result of an unbalanced motor or blower wheel. It is advisable to go to a professional if you hear thumping noises in your heater.

Humming – You may just have a loud transformer, but if your furnace is giving you issues and you hear a humming sound it could mean you are dealing with a bad interior capacitor or fan.

These are just a few of the sounds that you may be hearing from your furnace. Stay tuned for our next post where we will discuss three more sounds you may hear from a malfunctioning heater.
