Nothing is more disconcerting that a high-pitched squeal in the middle of the night. A squealing sound in your furnace is the result of metal on metal, and the source is usually a lack of proper lubrication on the fan belts. Sometimes the fan belts themselves become loose. 

Either way, this is a simple repair for a DIY enthusiast or a professional heating service in the Allentown area. 


A loud, banging sound coming from your furnace can be equally scary. During the winter months your furnace is working overtime. Its stop-start cycle can shake sections of the furnace’s sheet metal housing, specifically the access panel, loose. Fortunately, this is an easy fix that simply involves tightening the panels.   

Thumping or Scraping

Thumping and scraping sounds are both indicative of a problem with the blower wheel. Thumping results from the wheel being off balance, which can become a significant problem without professional intervention. 

Scraping is caused by a blower wheel that’s come loose from its mounts and is freely making contact with the housing. PA residents beware: this can cause catastrophic damage if not addressed by a professional!


A low-pitched rumble is an indication of a problem with your burner misfiring. Because many furnaces use gas, and carbon monoxide can build up inside your home, this can be a dangerous problem. Turn off power to your furnace and call a professional immediately!
