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:
- 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.
- Broken Blower Wheel – If the blower wheel is broken it will vibrate around in the housing, causing scraping, squealing, and banging sounds.
- 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.
