Why Does Your Furnace Need to Be Cleaned Every Year?

While your furnace works hard to heat your home, it’s a magnet for dust, dirt, and debris.  

Furnace cleaning is important to the health and function of your furnace and your greater central HVAC system. Air circulating through your furnace is distributed throughout your home—and any dust, dander, or mold spores in your unit is carried along with it.  

The benefits of furnace cleaning can’t be understated. With annual furnace cleaning and maintenance, you will:  

  • Save money on energy bills and maintenance: Impacted dust and dirt may negatively impact the efficiency of your HVAC system.  

  • Breathe cleaner air: Furnace cleaning is a crucial step toward improving the indoor air quality of your home. Clean air circulating through your ductwork is less likely to contribute to the spread of allergens or pathogens or the buildup of dust and particulates in your ductwork. 

  • Stay warm: No one wants to wake up on a frosty winter morning to discover their heater or furnace has broken down during the night.

What Does Furnace Cleaning Include?  

As a part of annual furnace maintenance appointment, our team will clean the furnace.  

These steps include (but are not limited to): 

  1. Carefully disassembling the unit casing to uncover vital components.  

  1. Cleaning dust and dirt from both internal and external components.  

  1. Inspecting and ensuring the heat exchanger is clean and functional. 

  1. Inspecting the condensate drain and any drain lines for potential obstruction.

Can I Clean My Furnace Myself?  

No, you should leave your furnace cleaning up to a professional HVAC technician. From blade fans to air filters and furnace flames, cleaning a furnace properly requires disassembling some of the unit’s casings and components—and the last thing you need is a puzzle to solve! Leave this job to experienced technicians with the tools and experience to clean, diagnose, and identify and fix any problems.
