New AC Unit Replacement & Installation in Phoenix

When repairs stop making sense, a properly sized, professionally installed high-efficiency system pays you back every single summer. We handle everything — sizing, permits, removal, installation, and testing — and stand behind the work.

Is it time to replace?

A good rule of thumb: if a repair costs more than half the price of a new system — or your unit checks several of these boxes — replacement is usually the smarter money.

📅

10–15+ years old

Arizona heat ages systems faster than almost anywhere else.

🧪

Uses R-22 refrigerant

Phased out — recharging an R-22 system is expensive and a dead end.

🔁

Frequent repairs

Two or more service calls a year means the failures won't stop.

📈

Rising power bills

Old units lose efficiency every season — you're paying the difference.

🌡️

Uneven cooling

Hot rooms and cold rooms point to a failing or wrongly sized system.

🔊

Loud operation

Modern systems run dramatically quieter than 15-year-old units.

Systems we install

Right-sized for your home, your ductwork, and the Valley's climate — from every major manufacturer.

🏠

Central Split Systems

The classic setup: outdoor condenser + indoor air handler or furnace coil.

🔄

Heat Pumps

Cooling and heating in one efficient unit — ideal for Arizona's mild winters.

🏘️

Rooftop Package Units

The all-in-one units common across Phoenix-area homes. We install and crane them.

📐

Ductless Mini-Splits

For additions, garages, casitas, and rooms the ductwork doesn't reach.

How installation works

From first call to cold air — typically within a few days, often with installation completed in a single day.

Free in-home estimate

We inspect your current system, ductwork, and electrical, and talk through your comfort issues and budget. No charge, no obligation.

Proper load calculation

We size the system to your actual home — square footage, insulation, windows, sun exposure — not a guess. Oversized and undersized units both cost you money.

Clear options & exact quote

Good / better / best equipment options with real prices, efficiency ratings, and warranty terms — explained side by side so you can choose.

Installation day

We protect your home, remove and haul away the old unit, set the new equipment, replace or flush the lineset, connect electrical and ductwork, and pull required permits.

Commissioning & testing

Refrigerant charge verified to spec, airflow balanced, thermostat configured, full cooling and heating cycles tested before we call it done.

Walkthrough & warranty registration

We show you how everything works, register your manufacturer warranty, and leave your home as clean as we found it.

Every installation includes

One price, everything handled — no surprise add-ons on installation day.
