2 HVAC Repair Issues That Homeowners Will Want To Learn More About

Many decades of innovations and improvements have made it possible for today's homeowners to enjoy the most efficient heating and cooling systems to date. In addition to improved efficiency, modern HVAC systems are better able to maintain healthy humidity levels while also filtering out many types of harmful allergens. 

With all these benefits, however, it is still important for homeowners to have a good understanding of some of the important HVAC repair issues they may experience. 

Draft Inducer

Furnaces that use propane or natural gas as fuel are equipped with a part called a draft inducer. Best described as an electrical fan, the draft inducer is part of the exhaust flue located at the end of the heat exchanger inside the furnace. Programmed to begin circulating air shortly before ignition takes place, the draft inducer helps maximize energy efficiency and push the warmed air farther into the home to ensure a more comfortable heating experience. 

A draft inducer must operate multiple times per hour, whenever ignition occurs and a burn cycle begins. This level of operation creates the potential for a substantial amount of wear to occur, making the part subject to failure. When a draft inducer has become worn and in need of replacement, homeowners may begin to hear rattling, clicking, or banging noises when the furnace ignition process begins.

While a furnace will continue to operate with a faulty or worn draft inducer, the level of heating efficiency and comfort will be reduced. If the draft inducer stops working, the furnace will not be operational until the failed part has been repaired or replaced. 

Blower Motor

Unlike the draft inducer which operates only during the heating season, an HVAC blower motor works whenever heated or cooled air is produced. Blower motors are responsible for circulating heated and cooled air throughout the home, a job much larger than that of the draft inducer. 

When a blower motor begins to become worn, homeowners may notice one or more signs, including noisy operation, weak airflow output, and higher energy bills. Blower motors that fail can put furnaces at risk of overheating while also causing the entire HVAC system to stop working. 

Homeowners who take the time to become familiar with how their HVAC system functions, including the normal sounds it makes, will be more able to detect when these types of repair issues are occurring. To discuss an HVAC system or schedule maintenance or repairs, homeowners should contact a reputable HVAC service provider in their immediate area.
