The difference is in the sizing

An oversized system short-cycles, leaves humidity behind, and dies young. An undersized one runs forever and never catches up. We measure your home — windows, insulation, ductwork, orientation — and engineer the system to match.

  • Manual J load calculation on every quote
  • High-efficiency AC, furnace & heat pump options
  • Duct repair, sealing & redesign
  • Permits, inspections & old-unit haul-away included

What a proper installation includes

Engineered sizing

Room-by-room load math, not square-footage rules of thumb. Right capacity, right airflow, right away.

Ductwork that delivers

We test static pressure and seal leaks — because a 16-SEER unit on leaky ducts performs like a 13.

Clean, one-day install

Drop cloths, shoe covers, photographed startup checklist, and a full walkthrough before we leave.

Registered warranties

We register your equipment for full 10-year parts coverage and back labor in writing.

Installation questions

One day for most full replacements. Ductwork redesigns or complex commercial jobs run two to three days — your written estimate states the exact timeline.

It depends on insulation, windows, ductwork, and orientation — not just square footage. Our free estimate includes a Manual J calculation that answers this precisely.

Yes — most of our installations use monthly plans with fast approvals. Many homeowners pay less per month than the energy savings the new system delivers.
