Quick answer
A new central air conditioner should be sized with a load calculation, not by guessing from the old unit. In Texas, look for a high-efficiency SEER2 rating, a properly matched indoor coil and installation by a licensed contractor. Most replacements are completed in one day, and financing can spread the cost over time.
AC Installation you can count on
Replacing an air conditioner is a major purchase, and the installation matters as much as the brand. An oversized system short-cycles and leaves your home clammy; an undersized one runs nonstop in August. We perform a load calculation to size your system correctly.
You get clear, side-by-side options at different efficiency levels, a written quote and a clean, one-day installation for most homes. We handle permits, haul away the old equipment and register your warranty.

What affects the cost of ac installation?
AC replacement cost depends on system size (tonnage), efficiency rating, whether the furnace or air handler is also replaced, ductwork condition and any electrical or line-set changes. Higher-efficiency systems cost more upfront and less to run. Ask about financing and available rebates from your electric provider.
