Parts we install
Premium, Long-Lasting Air Duct Parts
The part decides how long the repair lasts. Here is what we fit, and what the cheap version costs you later.
Air Filters
The filter is the only thing standing between your ductwork and everything floating through the house. Its rating decides how much of that actually gets captured.
What we install
We fit pleated media filters in the MERV 11 to MERV 13 range, cut to the return opening so air passes through the media instead of leaking around the frame.
What other companies fit
The usual swap is a thin fiberglass panel in the MERV 1 to MERV 4 range. It protects the blower and very little else, so fine dust goes straight back into the ducts.
Duct Sealing
Every joint and seam in a duct system leaks a little. How those joints are sealed decides whether the air you paid to heat or cool ever reaches the room.
What we install
We seal joints with brush-applied mastic reinforced with mesh tape. Mastic stays flexible, moves with the metal, and holds its seal through years of heating and cooling cycles.
What other companies fit
The quick fix is a wrap of cloth-backed duct tape. The adhesive dries out in attic heat within a couple of seasons, the tape curls off, and the joint is wide open again.
Flexible Duct
Flex duct feeds most bedrooms and upstairs registers. Its insulation value and inner liner decide how much air, and how much temperature, survives the trip.
What we install
We use R-8 insulated flex duct with a smooth inner core, pulled tight and supported every few feet so the run stays straight and open.
What other companies fit
Thin R-4 flex stapled up loose sags between supports. The deep ridges choke airflow and attic heat soaks straight through the light wrap before the air gets to you.
Vent Covers and Registers
Registers and return grilles are the visible end of the system. They also control how evenly a room actually gets its air.
What we install
We install steel registers with adjustable dampers and a powder-coated finish that stays true after repeated cleaning.
What other companies fit
Thin stamped or plastic grilles warp with heat, the louvers snap off, and the damper stops holding position, so the room is stuck wherever it was last set.
Dryer Vent Hose
The dryer vent run is the most common lint fire point in a house, and the material it is made from matters more than anything else about it.
What we install
We run rigid or semi-rigid metal dryer duct with smooth walls and taped metal joints, so lint keeps moving out of the house instead of collecting.
What other companies fit
The strip of thin foil or vinyl accordion hose behind most dryers crushes flat against the wall, traps lint in every ridge, and is the first thing an inspector flags.

What Our Customers Say
Homeowners in every market we serve, in their own words.
★★★★★
"Tech arrived with a badge and a printed sheet of what he'd be doing. Ran a camera through the main trunk before and after so I could see the dust difference. Vents smell cleaner already."
★★★★★
"Priced by the system, not by the vent, and he told me up front. No pressure to add the sanitizer and I said no without any fuss."
★★★★★
"We had construction dust packed into every register after a remodel. They sealed off the returns, used negative pressure, and left the floors cleaner than they found them."
★★★★★
"I liked that I knew who was coming in. Name and photo texted ahead, badge at the door. He was quiet, careful with the furniture, and thorough."
