Certified Air Duct Cleaning New Haven, CT

A flexible dryer duct slowly fills with lint until airflow is choked off. That restriction makes the dryer run hot and long, and a lint-packed run is a recognized fire hazard. Most homeowners never see it because the buildup sits inside the wall and roof run, out of sight behind the lint trap.

We clear the full run from the lint trap all the way to the exterior cap, working the line with a rotating brush and compressed air so the lint is pulled out rather than packed tighter. We check the transition hose, the wall and roof run, and the exterior flap, then confirm the cap opens freely under real airflow.

With the run cleared end to end, the dryer vents the way it is meant to, drying loads faster and reducing the fire risk a clogged line carries. We confirm airflow at the exterior cap before we leave and walk you through what we found and cleared.

Years of dust settle inside the supply and return trunks, and in a damp system that layer can support microbial growth. Once it coats the duct walls, every cycle of the blower has the chance to move some of it back into the rooms you live in. Surface fogging or a quick vacuum at the registers does not reach it.

We clean to the NADCA ACR-2021 source-removal standard. The system is put under HEPA-filtered negative air so the duct is held under suction, then we agitate the interior surfaces with rotary brushes and air whips. Because the trunk is under negative pressure the loosened debris is captured at the collection unit, not pushed around the home.

Source removal takes the dust and growth out of the system rather than just disturbing it, so what was coating the ducts ends up in the HEPA-filtered collection, not back in your air. We document the before and after condition of the trunks so you can see what was removed.

Dirt and biofilm build up on the evaporator coil and inside the air handler cabinet, where the air has to pass through the fins. As that layer thickens it chokes airflow, drops the systems efficiency, and gives moisture a place to hold against the coil, which is exactly where odors and growth tend to start.

We open the cabinet and clean the evaporator coil and surrounding surfaces, clearing the fins and the drain pan so air moves through freely again. Where it is warranted we apply an EPA-registered coil treatment rated for that use, then confirm the condensate path is draining the way it should.

With the coil and cabinet clean, air passes through the fins instead of fighting a clogged surface, which helps the system move air and shed heat the way it was designed to. We show you the coil before and after so the difference is on record, not just described.

The squirrel-cage blower wheel is the part that actually moves your air, and each small fin packs with dust over time. A caked wheel scoops far less air per turn and throws the wheel out of balance, so the motor works harder and the whole system delivers weaker airflow to every room.

We pull the squirrel-cage wheel where the unit allows it and deep-clean each fin so the blades regain their shape and grip on the air. Cleaning the wheel off the shaft lets us reach the packed inner faces a register vacuum can never touch, then we reseat it true so it spins balanced.

A clean, balanced wheel moves the air it was rated to move, so registers breathe again and the motor is not fighting a loaded wheel every cycle. We note the wheels condition before and after so the work is documented.

The blower housing and the motor area collect a heavy pack of dust because all the conditioned air passes through them. That buildup sits right at the heart of the system, so on every cycle some of it gets stirred up and recirculated through the home, feeding the dust you keep wiping off surfaces.

We clean the housing, the wheel, and the motor area so the air is moving through clean components instead of a dust-loaded chamber. Reaching the housing and motor area means opening the unit rather than cleaning from the registers, which is the only way to clear the dust that actually recirculates.

With the housing and motor area cleared, the air leaving the system is moving through clean parts instead of picking up old dust on the way out, which means cleaner air output to the rooms it serves. We document the housing condition before and after.
