AC Installation & Replacement in Gilbert, AZ
Free in-home estimates. Sized for your house, permitted and inspected.
Thinking about a new AC?
Maybe your system is 15 years old and the repairs keep coming. Maybe an R-22 leak just turned a small fix into a big one. Either way, the first step is a free in-home estimate. We look at the house, the ductwork and the equipment you have now, then give you a written price for a system that fits.

Sized for your house, not copied from the old unit
A lot of Gilbert homes still have whatever size system the builder put in 20 years ago. Since then you may have added windows, more attic insulation or an Arizona room that's now real living space. We run a Manual J load calculation on every replacement. An oversized unit short-cycles, leaves the air clammy and wears out early. An undersized one runs all afternoon in July and still can't keep up.
Two-story homes need a closer look. If upstairs is always hotter, the answer might be duct changes or a second system rather than a bigger unit, and we'll walk through it with you at the estimate.
Install day
Our crew removes the old condenser and air handler, checks the ducts for leaks and crushed runs, and replaces the line set when it's worn instead of reusing it. We pull the permit with the Town of Gilbert and schedule the inspection, so the job is documented to code if you sell the house later. Once the new system is running, we test static pressure, confirm the refrigerant charge and go over the thermostat with you.
Your written price covers the equipment, labor, the permit and hauling away the old unit. If your HOA has rules about outdoor equipment, bring them to the estimate and we'll plan around them.
Brands, warranty and financing
We install and service every make, and we're an authorized dealer for Carrier, Goodman, A/C Pro and Ruud. The manufacturer's warranty covers the equipment, and our workmanship guarantee covers the installation. Financing through home-service lenders includes 0% promotional plans for qualifying applicants, with approved credit, and most applications get a decision in minutes.
To keep the new system in shape, the Iron Horse Advantage membership is free for your first system and includes a spring AC visit and a fall heating check.

Frequently asked questions
How much does a new AC cost in Gilbert?
It depends on the size of the house, the type of system and what the ducts need. The estimate is free, and you get a written price covering equipment, labor, the permit and removal before you decide anything.
Do you handle the permit?
Yes. We pull the Town of Gilbert permit and schedule the inspection as part of the job.
Can you just match the size of my old unit?
We'd rather not guess. The old unit may have been the wrong size from the start, and your home has probably changed since. A Manual J calculation settles it.
Do you offer financing?
Yes, through home-service lenders, including 0% promotional plans for qualifying applicants with approved credit. Most applications take a few minutes.
