How long does a full AC installation take?

Most residential change‑outs (replacing an existing unit) take one day — typically 6 to 8 hours. If ductwork needs modification, add another half day. We start early and work until it's running right.

Do I need a permit for AC replacement in Arizona?

Yes — most cities in Arizona require a mechanical permit for AC replacement. We handle all permitting and inspections. It's included in our quote, so you don't have to deal with city hall.

What size AC do I need for my home?

Square footage alone doesn't tell the whole story. We need to know your insulation, window orientation, shade, and duct condition. A 3‑ton unit might be right for one home but wrong for another. We calculate using Manual J — never guess.

Do you offer financing for new AC installations?

Yes — we partner with third‑party financing providers. Ask us for details. Many approved customers get low monthly payments with 0% interest options.

When Replacement Makes Sense (Not Another Band‑Aid)

Before committing to a new system, we run the numbers with you. We adhere to a strict Fix‑First Philosophy—if your current AC can be safely and economically repaired, we will always suggest that first.

System Age 12–15+ Years

The Reality: Older units are reaching the end of their design life in the desert. They operate on outdated, expensive refrigerants (R‑22) and draw double the power of modern systems. Replacing them can slash your summer power bills by 30‑50%.

The "50% Rule" on Repairs

The Reality: If a single major repair (like a failed compressor or compromised coil) costs more than 50% of the price of a brand‑new unit, dumping more money into it is a bad investment. We'll show you the exact break‑even math.

Uneven Cooling & Runaway Bills

The Reality: If your system runs continuously, struggles to keep your home below 80°F, and your utility bills are skyrocketing, your compressor is likely losing mechanical efficiency. A new properly sized unit pays for itself over a few hot summers.

The Alphas Standard: Why Our Installations Outlast Low‑Bid Competitors

We work with leading brands like AC Pro, Trane, Carrier, Lennox, and Rheem, and we back our installations with a solid warranty.

Precision Sizing (Manual J Load Calculations)

Most HVAC contractors size units based on a lazy rule‑of‑thumb ("1 ton per 500 square feet"). This leads to oversized systems that short‑cycle, leave high humidity, and burn out early. We calculate your home's exact heat load using room measurements, window orientations, insulation values, and ductwork design.

Nitrogen‑Purged Brazing

When copper refrigerant lines are welded (brazed) together, the heat creates black copper oxide scale inside the pipe. If a technician doesn't run dry nitrogen through the pipe during this process, that scale flakes off into your brand‑new system, clogging the delicate thermal expansion valve (TXV) and killing your compressor in 3 to 5 years. We purge with nitrogen on every single job—no exceptions.

Deep Vacuum Evacuation (Below 500 Microns)

Moisture and non‑condensable air are the absolute enemies of modern refrigerants. We use industrial vacuum pumps and digital micron gauges to pull your system down below 500 microns. This boils off any microscopic moisture and ensures an airtight, contamination‑free loop for maximum cooling efficiency.

Custom Ductwork Integration

We don't just "slap and tape" your new unit to the old plenum. If your return air plenum or supply ducts are restricted, your new high‑efficiency AC will choke. We custom‑fabricate transition fittings on‑site to ensure seamless, aerodynamic airflow.

Our Step‑by‑Step Installation Process: Done Right

1. Comprehensive Home Evaluation

We measure your rooms, assess attic insulation, inspect windows, and run a complete Manual J calculation to find your home's exact BTU requirements.

2. Clear Quote & Rebate Integration

You receive an itemized, transparent quote showing equipment costs, labor, permits, and old unit disposal fees. We automatically apply any eligible manufacturer discounts and prepare your documentation for SRP or APS rebates.

3. Clean Removal of Your Old Unit

We carefully pump down and recover your old refrigerant into certified cylinders according to EPA guidelines, disconnect the old system, and thoroughly scrub the platform pad clean.

4. Meticulous System Setup

We install your new condenser, evaporator coil, and line sets. We execute our nitrogen‑purged brazing process, install dual inline filter driers, and pull a certified deep vacuum.

5. Dynamic Startup & Commissioning

We don't just flip the switch and run. We weigh in the exact factory refrigerant charge adjusted for line length, measure operational pressures, check air temperature split, and run the system for at least 30 minutes to verify stable performance.

6. Owner Walkthrough & Spotless Cleanup

We show you how to program your new thermostat, review maintenance schedules, and register your factory warranties on your behalf. We sweep the workspace and leave your home cleaner than we found it.

Mesa Homeowners Ask About AC Installation

How long does a full AC replacement take?

A typical residential change‑out (replacing an existing outdoor condenser and indoor evaporator coil) is completed in a single day—usually taking 6 to 8 hours. If we need to modify or rebuild major sections of your ductwork, we will communicate that upfront, which may add an extra half‑day. We start early to make sure your home is cool before the evening.

Do I need a permit for an AC replacement in Mesa?

Yes. Most cities in the East Valley, including Mesa, Gilbert, and Chandler, require a mechanical permit for split‑system replacements. Alphas handles the entire permitting process, schedules the city inspection, and makes sure everything is 100% compliant with local codes. We include the permit fee in our transparent quote—there are no surprise charges.

What size AC does my house actually need?

Square footage is only part of the puzzle. An 1,800 sq. ft. home with updated dual‑pane windows and great insulation might only need a 3‑ton system, whereas a home of the same size with single‑pane windows and poor insulation could require a 4‑ton unit. Installing an oversized unit is a costly mistake. We run a certified Manual J load calculation on every home to get your sizing exact.

Should I get a higher SEER rating in Arizona?

Yes. In Arizona, where we run our AC units for 8 to 9 months of the year, investing in a higher efficiency system (SEER2 16 or 18) pays back significantly faster than in milder climates. We will map out your estimated monthly energy savings versus the upfront equipment cost so you can make an educated, math‑backed decision.

What brands do you install?

We prefer AC Pro systems because their engineering holds up phenomenally well under extreme Arizona temperatures and they offer excellent local warranty support. However, we are completely brand‑certified and install all major manufacturers, including Trane, Carrier, Lennox, Rheem, and Goodman. We focus on finding the best value and system design for your budget.

Are there financing options available?

Yes. We understand that a sudden system failure is a major unplanned expense. We partner with leading home‑improvement financing providers to offer flexible plans, including low monthly payment options and 0% promotional interest terms for approved buyers. We will walk you through the simple application process.

What's included in your AC installation service?

Our installation includes: removal and disposal of your old unit, Manual J load calculation, new condenser and evaporator coil placement, new line set (if needed), electrical connections, drain line setup, refrigerant charge, system startup and performance testing, and a full walkthrough. We also handle permits and offer a comprehensive warranty on equipment and labor.
