New Systems

The right system, installed right.

A new system is a big decision, and the size matters more than the brand. Too small and it never catches up on a 110° afternoon; too big and it short-cycles, wears out early and leaves the house clammy during monsoon season. We size every system for the building — not for the biggest box on the truck.

We install residential split systems and package units and heavy commercial rooftop units — including lineset insulation, safety disconnects, duct connections and startup testing. Goodman, Carrier, Trane, Rheem, Daikin, American Standard and more.

Every installation includes

  • A load-based size recommendation
  • Removal of the old equipment
  • Lineset insulation and safety disconnect
  • Duct and electrical connections
  • Startup testing and a walkthrough

Time to replace when…

  • The system is past 12–15 years and needs a major repair
  • It can’t keep up on the hottest days
  • Repairs have become a yearly bill

Questions

HVAC Installation FAQ

How do I know what size AC I need?

It depends on the square footage, insulation, windows, sun exposure and ductwork — not just the size of the old unit. We look at the building and recommend a size based on the load.

Which brands do you install?

Goodman, Carrier, Trane, Rheem, Daikin, American Standard, Bosch, Midea, Day & Night, Evcon and more.

Do you install commercial rooftop units?

Yes — including crane lifts, duct connections and safety compliance. See our work for a recent commercial install.

Do you take away the old unit?

Yes, removal of the old equipment is part of the installation.
