There can be many reasons for which the furnace or air conditioners has to be changed or replaced. The furnaces have to be changed or replaced in case they produce excessive noise. If the equipment is making a lot of noise while running, it may indicate wear in the moving parts. In an older unit, noise is a sign of parts wearing out, and that rubbing and rattling is starting to occur.2b

It may be possible to replace the worn parts, but usually by the time the noise is noticeable, the cost of replacement parts outweighs the price of a new HVAC system. Professional heating contractors will be able to examine the equipment and determine whether replacement or repair is the more advisable option.2b1

Another reason for the furnace to be changed or replaced can be diminishing of the indoor air quality. An aging HVAC system can begin to leak, spewing dust particles into the air and reducing indoor air quality. Over time, the heat exchanger in a furnace develops holes and cracks.

These cracks may release carbon monoxide into the air. It’s important that carbon monoxide detectors be used whenever the system is in use, and that home and business owners are aware of any smell of exhaust. Another telltale sign is soot buildup around vents and around the furnace itself
