Air Conditioning Installation in DFW
Texas AirZone installs and replaces home air conditioning across the Metroplex. We size a proposed system by measuring the actual house, not by simply matching the old unit.

The Design Comes Before the Equipment
If we just match the label on your old unit, we also inherit every sizing mistake that was made when it was first installed. Instead, we start by measuring your actual house: how it holds heat, where it loses it, and what your ductwork can actually deliver room by room. Even a correctly sized system will underperform if the ductwork underneath it cannot keep up.

Schedule ServiceWhat You Receive Before You Commit
Before you decide anything, you receive mechanical drawings, material samples, and one clearly defined proposal. The proposal documents the scope, current terms, and expected timeline so you know what you are approving before work is scheduled.
Installation Day
Before work is scheduled, the proposal identifies the installation scope, responsible team and expected timeline for the project.
What Gets Sized Wrong in North Texas
We see two mistakes over and over across the Metroplex, and both come from treating size as the only thing that matters.
- Sizing for the worst afternoon of the year. A system built to handle a 100-degree day spends the rest of the season turning on and off too quickly. It hits your thermostat setting fast, but never runs long enough to pull the humidity out of the air, so your house reads 72 degrees and still feels damp.
- Ignoring the ductwork. In homes with ductwork affected by age, access limitations or structural movement, leakage can reduce the air reaching living spaces. Airflow and pressure testing can help determine whether the duct system is contributing to the problem.
Refrigerant in New Systems
Most newly manufactured residential systems now use lower-GWP refrigerants such as R-454B or R-32. Federal rules restricted the manufacture and import of new higher-GWP residential split-system equipment beginning January 1, 2025. Existing R-410A systems can still be serviced, and eligible equipment manufactured before the cutoff may still be installed under current sell-through rules.
After Installation
After installation, review the completed work and any applicable parts, labor or ongoing-care terms with the team.
How long does an AC replacement take?
Most residential AC replacements can be completed within a day, though the timeline depends on the equipment, installation conditions, ductwork, electrical requirements, and whether additional modifications are needed.
Why is a load calculation important before replacing an AC system?
A load calculation sizes the replacement HVAC equipment to the home's current heating and cooling needs rather than assuming the previous equipment was correctly sized. It accounts for factors such as insulation, windows, layout, and other conditions that affect the home's load.
Who will perform the installation?
The written proposal identifies the responsible installation team and project scope before work is scheduled.
How is pricing presented?
The written proposal explains the scope, pricing basis, selections and any assumptions so you can review what is included before work is scheduled.
What refrigerant will a new system use?
New residential HVAC systems may use lower-global-warming-potential refrigerants such as R-454B or R-32 depending on the manufacturer and equipment. Existing R-410A systems can still be serviced, so the refrigerant used in a new installation depends on the specific equipment selected and current regulations.
Does Texas AirZone offer free second opinions on HVAC replacement quotes?
Yes. Texas AirZone offers second opinions on HVAC replacement recommendations so homeowners can compare the diagnosis, proposed scope, and replacement reasoning before committing to a new system.
Does Texas AirZone subcontract HVAC installations?
No. We perform our own HVAC installations rather than subcontracting the installation work.
Does Texas AirZone provide fixed-price HVAC replacement quotes?
Texas AirZone provides a fixed project price for its HVAC replacement proposals rather than an open-ended estimate, with the proposed scope documented before work is scheduled.
