AC Installation in McKinney, TX
Your AC shouldn't be a liability every summer. Whether you're replacing an aging system or installing for the first time, Texas 1st Choice Heat & Air handles the full process — from right-sizing your equipment to the moment cool air hits every room.
Signs Your AC System Needs to Be Replaced — Not Repaired Again
When your air conditioner starts losing the battle against a Texas summer, the symptoms are hard to ignore — and expensive to keep patching. An aging or undersized system doesn't just fail to cool: it runs constantly, drives up your electric bill, leaves rooms feeling muggy, and gives out at the worst possible moment. The longer you keep repairing a system past its prime, the more you spend on borrowed time.
- Your system is 10–15 years old and repairs are adding up
- Your home never quite reaches the set temperature, even on mild days
- Humidity feels high indoors regardless of how long the AC runs
- Your energy bills have climbed without any change in usage habits
What Our AC Installation in McKinney Includes — Start to Finish
A new air conditioner is only as good as the installation behind it. We don't just swap out equipment — we engineer the right setup for your home. Every install starts with a Manual J load calculation that accounts for square footage, ceiling height, insulation, window orientation, and heat load. Getting the size right before ordering equipment is what separates a reliable system from one that underperforms from day one.
Load Calculation & Equipment Selection
Manual J load calculation to determine the correct tonnage, then a recommendation from Amana's high-efficiency lineup matched to your home and budget.
Removal & Site Prep
EPA-compliant refrigerant recovery, safe removal of the old condenser and air handler, and full inspection of the pad and existing line set before any new equipment is set.
Installation & Line Work
New condenser set on a level pad. Air handler mounted and connected to existing ductwork. New or flushed refrigerant lines. All electrical connections made to the disconnect box and breaker panel.
Pressure Test, Vacuum & Charge
Nitrogen pressure test to confirm line integrity, deep vacuum evacuation to remove moisture and non-condensables, then refrigerant charge to manufacturer specification.
Startup & Homeowner Walkthrough
Full startup sequence — temperature differential, airflow, refrigerant pressure, and thermostat calibration. Before we leave, you know how to run the system, when to change the filter, and what your warranty covers.
As an authorized Amana dealer, we match you to a system built for North Texas conditions — one that carries some of the strongest manufacturer warranties in the industry. You go from an aging, energy-draining unit to a quiet, efficient setup that handles McKinney summers the right way.

How Our AC Installation Works — From First Call to First Cool Air
System Selection and Right-Sizing
We assess your home's square footage, ceiling height, insulation, and window exposure — then run a Manual J load calculation to identify the exact tonnage your home needs before recommending equipment.
Old System Removal and Site Prep
Your existing condenser and air handler are disconnected, refrigerant is recovered using EPA-compliant equipment, and both units are safely removed. The pad and line set are inspected and prepped.
New Equipment Installation and Line Work
The new condenser is set on a level pad, the air handler is mounted and connected to your ductwork, refrigerant lines are run or flushed, and all electrical connections are made.
Pressure Test, Evacuation, and Refrigerant Charge
Lines are pressure-tested with nitrogen, then evacuated with a vacuum pump. Once the vacuum holds, the system is charged to manufacturer refrigerant specification.
Startup, Verification, and Homeowner Walkthrough
We run a full startup sequence — temperature differential, airflow, refrigerant pressure, and thermostat calibration. Before we leave, you know exactly how everything works.
