AC Installation & Replacement in Central Texas
New air conditioner installation and system replacement from HVAC Done Right, with load-based sizing, correct airflow, and a clean changeout across Austin, San Antonio, and nearby cities.
Open 24/7, every day
Replacing an air conditioner is one of the larger decisions a homeowner makes about their house, and the quality of the installation matters as much as the equipment on the label. HVAC Done Right sizes replacements to the home, not to the box that came out.
We walk the house, measure what the existing ductwork can actually move, and talk through efficiency options in terms of what they mean for your comfort and your utility bill instead of pushing the largest system available.
How we scope a replacement
A replacement quote starts with a walkthrough: square footage, window exposure, insulation, attic conditions, existing duct layout and condition, electrical service, and the drain and pad situation outside.
Oversized equipment short cycles, leaves humidity in the house, and wears out early. Undersized equipment never catches up in August. Correct sizing is the single biggest lever on how a new system feels.
What a professional changeout includes
- Recovery of existing refrigerant in line with EPA requirements
- New line set or verified flush of the existing one, depending on refrigerant type
- Correct evaporator coil match and a properly sealed plenum transition
- New pad, disconnect, and whip work as needed at the outdoor unit
- Condensate drain, trap, float switch, and secondary pan correction
- Airflow setup and static pressure check, then charge verification by measurement
- Thermostat setup and a walkthrough of how to run the system
- Haul-away of the old equipment
Choosing between a repair and a replacement
If your system is under about ten years old and the failure is a single component, repair usually wins. As equipment passes the twelve to fifteen year mark, repeats stack up and efficiency has already slipped, which shifts the math toward replacement.
Systems that still use R-22 refrigerant are a special case: that refrigerant is no longer produced, so leak repairs get expensive fast. We lay out both paths with real numbers for your system and let you decide.

Frequently asked questions
- How long does a replacement take?
- A straightforward residential changeout is typically completed in a day. Jobs that involve duct modifications, electrical work, or attic access changes can run longer, and we tell you that before we schedule.
- Do I have to replace the indoor and outdoor units together?
- In most cases yes. Mismatched indoor and outdoor components do not hit their rated efficiency and can create reliability and warranty problems.
- Will a bigger system cool my house better?
- Usually the opposite. An oversized system satisfies the thermostat quickly, shuts off before it removes humidity, and leaves rooms feeling clammy while wearing out the compressor.
