Replacing your AC is the biggest home-comfort decision most Houston homeowners make. A local installer who measures your home, sizes the system properly, and quotes in writing — before any work starts.
The difference between a good installation and a bad one is measured on site, before the quote.
An air conditioner is not a commodity you buy by the ton and bolt to the wall. It is a system that has to match your home — its size, its insulation, its windows, its orientation, and its ducts — and in Houston, where the AC runs nine months of the year, a wrong size punishes you every single month. An oversized system short-cycles: it cools fast, shuts off, and leaves the humidity behind, so the house feels clammy even at 72 degrees. An undersized system runs all day and never catches up in August. Both cost you money for years, and both are invisible on a quote that never measured your home.
That is why our free estimates start with a load calculation, done on site: rooms measured, insulation checked, windows counted, ducts inspected. The result is a system sized for your house, quoted in writing, with every component named — brand, model, SEER2 rating, and coil — and every cost listed, including duct repairs, electrical work, and permits where required. Full replacement in the Houston metro runs $4,500–$9,500, and where you land in that range is decided by size, efficiency, ductwork, and access — all of which are visible on the quote before you approve anything.
Local matters for installation more than for any other service, because the installer is the one who has to come back if something is wrong. We are based at 1200 Main St, Houston, TX 77002, licensed under Texas TACLB #TX-88214, and our technicians are NATE-certified. The installation is commissioned on the day — pressures, airflow, and temperature drop verified before the crew leaves — and the work carries our 1-year written repair warranty on top of the equipment warranty. If the system does not perform as quoted, you know exactly where to find us.

The answers tell you more than the price does.
First, ask how the size was calculated. If the estimator never measured a room, never looked at the ducts, and never asked about insulation, the size is a guess — and a wrong size costs you comfort and money for the life of the system. A proper estimate takes time on site, and it is free with us. If the answer is 'we go by square footage,' keep shopping.
Second, ask what is named on the quote. The brand, the model, the SEER2 rating, the coil, the ductwork, the electrical work, and the permits should all be listed. A quote that says 'new 3-ton system — $6,000' is not a quote, it is a mystery, and mysteries get expensive halfway through the job. Our quotes name every component and every cost.
Third, ask who comes back if something is wrong. A national call centre cannot send a technician to your door; a local company based in Houston can, and does, because its reputation is in the same city as its customers. We are at 1200 Main St, Houston, TX 77002, and every installation carries a 1-year written repair warranty on top of the equipment warranty. That is the answer that matters most.

A straightforward replacement usually takes one day. Jobs needing ductwork, electrical upgrades, or permits take longer — you get a written schedule before work starts.
If the system is 12–15+ years old and the repair is major ($1,200–$2,800), replacement usually wins. We quote both options side by side.
