What’s a little dirt and debris, right? According to HVAC experts, the buildup can be brutal for major household appliances like the furnace. These appliances are generally located in basements or utility rooms, which most homeowners don’t pay close attention to, especially if they’re cluttered or dusty. However, the accumulation of dirt on a furnace’s complicated components can erode the appliance’s performance and reliability over time. Check out the professional tips HVAC techs are sharing.

Reduced Airflow

Dust and debris can find their way into your furnace through your home’s return vents. While your unit circulates air, it draws in airborne dust and particles from these vents. Also, if you don’t replace or clean your furnace’s filter regularly, it can become clogged and allow dust to sneak in.

Reduced airflow is never good for a furnace, especially when components, including the blower motor and air ducts, are weakened by grime. This alone can restrict the flow of air throughout the system. Then, the furnace will work extra hard to circulate warm air. This means increased energy consumption and higher energy bills.

Underheating or Overheating

Your furnace can also underheat when dust and dirt insulate the heat exchanger, a key component. This can result in poor heat transfer and forces the furnace to run longer to reach the right temperature. The entire system wears out more quickly than it should. Your furnace can also overheat due to trapped grime, leading to breakdowns that require professional repair.

Clogged Moving Parts

Another problem that can develop affects moving parts such as the blower motor and fan. Again, dirt accumulates, and these components become clogged, causing friction and wear or dreaded motor burnout.

In addition to these issues, a dusty thermostat can put extra strain on the system. The thermostat will deliver inaccurate readings and cause your furnace to cycle on and off.

Strange Noises, Too

Your furnace could be making unusual noises to tell you it’s dusty and filled with debris. If you hear buzzing, rattling or grinding coming from your furnace, HVAC technicians say these red flags can indicate that dust and debris are causing internal components to wear down or move improperly. Don’t ignore the strange noises. It’s always best to call in the professionals for immediate attention.

A bit of dust and grime may not seem like a big deal, but if it’s around your furnace, beware. The buildup can hamper this household appliance’s overall performance and even affect your home’s indoor air quality. You need to keep the area around your system clean and schedule regular maintenance. Call our team at C&C Myers to book furnace services in the Charleston, SC area.
