Sizing first. Equipment second.
A new AC installation is more than picking a unit off a truck. We start with a real load calculation — home size, insulation, window exposure, ceiling height — before recommending any specific system size. An oversized system costs more upfront and wears out faster from short-cycling; an undersized one runs constantly and never quite keeps up. We size it right the first time, and give you a written scope and price before any work begins.
Whatever the reason, we scope it properly
First-time central air
Adding AC to a home that’s never had it — window units or swamp coolers replaced with a properly ducted, whole-home system.
Room addition or remodel
Extending existing ductwork or adding a dedicated zone so the new square footage is actually comfortable, not an afterthought.
New construction
Full system design and install for new builds — see new construction HVAC for scope specific to builders and general contractors.
Ductless mini-split
No ductwork needed — ideal for additions, garages, or homes where running new ducts isn’t practical. See ductless mini-split for details.
Heat pump systems
Combined heating and cooling in one system — see heat pump services to see if it fits your home.
Commercial installation
New system installs for offices, retail, and light industrial spaces — see commercial HVAC for that scope.
From load calculation to a running system
Free load calculation
We assess your home’s actual cooling needs on-site — not a phone estimate based on square footage alone.
Written scope & price
A clear quote covering equipment, ductwork if needed, and electrical work — before any commitment.
Scheduled installation
Most standard installs are completed in a day; larger projects involving ductwork take longer, with a realistic timeline given upfront.
Video-documented completion
You get a completion video showing the finished system, plus written warranty terms for your records.

If your current system is failing and you’re deciding between fixing it and replacing it, start with AC repair. If you’ve already decided to replace an existing system rather than install new, see AC replacement instead. If it’s your furnace rather than your AC, see furnace repair or furnace installation.
$0 down, 0% interest for up to 5 years
Most homeowners are approved same day with no hard credit pull. See HVAC financing for full terms and real payment examples.

Very professional, detailed and friendly. Diagnosed the problem quickly and had it fixed the same day. Tune-up price was reasonable.
Raul really explained everything and took pictures so we could see before and after. Typing this in the cool comfort of my fixed AC. Thanks!
Tony was very professional and thorough. He took the time to answer my questions and listen to my concerns about my AC unit.

AC installation FAQ
How is a new installation different from a replacement?
Installation covers a system going into a home for the first time, or a case where sizing and ductwork are being reassessed from scratch. If you’re swapping an existing system without changing scope, see AC replacement instead.
How do you determine the right system size?
We perform a real load calculation on-site — square footage, insulation, window exposure, and ceiling height — rather than sizing based on square footage alone. This avoids both an oversized system (higher cost, shorter equipment life) and an undersized one (poor performance).
How long does installation take?
Most standard installs are completed in a single day. Larger projects involving new ductwork or electrical panel work take longer — your estimator gives you a realistic timeline during the free assessment.
What’s included in the quote?
Equipment, standard installation labor, and a written warranty. Ductwork and electrical panel upgrades are scoped and quoted separately if your home needs them, identified during the free assessment rather than discovered mid-project.
Do you offer financing?
Yes — $0 down, 0% interest for up to 5 years on qualifying installs, with same-day approval and no hard credit pull in most cases. See HVAC financing for full terms.
