Your furnace blower moves every cubic foot of air in the house, and its wheel collects a layer of dust that unbalances it, cuts airflow and makes the motor work harder. Just above it, the evaporator coil is a wet, cold, fin-covered surface that catches whatever the filter missed and grows a film of dust and biological growth that blocks airflow and smells.
Bison cleans the blower assembly and the accessible coil surface as part of every whole-home duct cleaning, and as a standalone service for homes whose ducts are clean but whose system is dirty, dusty or losing airflow.
What's included in our furnace, blower & coil cleaning
- Blower wheel removed when possible, or cleaned in place with brushes and HEPA vacuum
- Blower compartment and housing vacuumed and wiped
- Evaporator coil surface cleaned with a no-rinse foaming coil cleaner
- Condensate drain pan checked and cleared
- Return plenum and filter rack vacuumed, new filter installed
- Static pressure and airflow check before and after
Why a dirty blower and coil cost you money
A coil coated in dust insulates itself from the air passing over it, so the system runs longer to reach the thermostat setting. A dirty blower wheel loses a surprising share of its airflow, which shows up as rooms that never quite get warm or cool, longer cycles and, eventually, a failed motor. Cleaning both is one of the cheapest efficiency gains available for a forced-air home.
How this differs from an HVAC tune-up
An HVAC contractor's tune-up checks refrigerant, electrical and combustion. It rarely includes pulling the blower or deep-cleaning the coil, because that is time-consuming cleaning work rather than mechanical service. We do the cleaning; if we find a mechanical problem we tell you and refer you to a licensed HVAC contractor.
Signs your furnace and coil need cleaning
- Weak airflow from the vents even with a new filter
- A dusty or musty smell when the system runs
- A "dirty sock" smell when the AC first starts
- Visible dust on the blower fins through the access panel
- Higher energy bills without a change in use

Furnace, Blower & Coil Cleaning: frequently asked questions
How often should the blower and coil be cleaned?
Every three to five years alongside duct cleaning, or sooner if the filter has been neglected or the home has pets.
Can you clean the coil without removing it?
In most furnaces we can access the coil face through the cabinet and clean it in place with foaming cleaner and a soft brush. Deeply fouled coils that need pulling and pressure washing are referred to an HVAC contractor.
Do I still need duct cleaning if you clean the furnace?
If the ducts are clean, no. We photograph inside the trunk line first and only recommend duct cleaning if there is debris to remove.
