Comfortable Units. Quiet Walls. Done Right the First Time.
We thread ductwork through tight chases and drop mini-splits into high-rise mechanical closets — the jobs most techs won't even bid. Fixed-price proposals. No surprises.

THE PROCESS
Your Project Plan, Step by Step
Click any phase to see the real photo, plain-language explanation, and typical timeline. No vague promises.
We photograph every lineset path, measure BTU demand room by room, and flag any structural or code issues before a single dollar changes hands. You receive a marked-up floor plan and a written load calculation report within 48 hours.
Every proposal names the exact Mitsubishi, Daikin, or Carrier model being installed, lists material quantities, and breaks out the permit fee line by line. If the scope changes at your request, you approve a written change order before work resumes.
Our permit coordinator has filed over 600 multi-unit HVAC permits. We know which jurisdictions require stamped engineering and which HOA boards want noise attenuation specs. We handle it and send you confirmation when approvals land.
We stage equipment in your loading dock or parking area the morning before, so install day starts at 8 AM with everything on-site. Copper linesets are brazed, not flared. Condensate lines pitch to drain. Every penetration is fire-stopped and sealed before the crew leaves.
You're present for the walkthrough. We show you the thermostat controls, explain the filter schedule, and confirm the noise level at the nearest bedroom wall. You receive digital copies of the permit, commissioning report, and equipment warranty registration.
No commitment. We survey, you decide.

What Condo Boards & Property Managers Say
“We had noise complaints from three units about the old compressor rattling through the walls. Airflow re-routed the linesets, installed a Mitsubishi hyper-heat system, and the complaints stopped the same week. Board meeting was the easiest I've run in years.”
Margaret Okonkwo
Condo Board President · The Harrington, 48-unit mid-rise
“I manage 22 townhouse units and needed all of them re-ducted over a summer without displacing a single tenant. Airflow phased the work by building wing, kept every unit habitable, and came in on the fixed price. Not one tenant complaint.”
Derek Vasquez
Property Manager · Millbrook Commons Townhomes
“That 1991 furnace was wedged under the stairs in a 3-foot clearance. Every other contractor told me I'd need structural work. Airflow's tech measured it, proposed a slim-duct mini-split, and finished in two days. The mechanical room is actually usable now.”
Priya Nair
Townhouse Owner · Private residence, 3-story townhouse
“The HOA approval process alone would have taken me months. Airflow's permit coordinator handled the stamped drawings, the noise attenuation spec sheet, and three rounds of board revisions. I signed off on the final approval in six weeks.”
