AfterAC Installation in Houston, TX
A new AC installation in Houston typically runs between $4,800 and $11,400 for a complete system replacement, depending on home size, efficiency rating, and ductwork condition. Most installations take one full day when the existing ductwork is sound, and we provide a written price before any equipment is ordered. If your current system is over 12 years old or has needed multiple repairs in the past two years, a replacement usually costs less in the long run than continuing to patch an aging unit.
Cold Harbour Heating and Air Houston handles full-system AC installation for homes across the Houston metro, from Katy to Clear Lake to The Woodlands. We’re the locally operated face of the Kingswell Guarantee, founded in 2003 and built on a simple idea that still holds: put the price in writing before the work starts, show up in the window you promised, and back the installation with a guarantee that means something. If you’re weighing repair against replacement, start with our AC Repair & Installation in Houston page for a fuller picture, then call (832) 371-9862 when you want a straight answer about your home.
We carry and install equipment from Carrier, Trane, and Lennox, and our technicians train on nine major residential brands, so we’re not steering you toward whatever happens to be in the warehouse. The right system for a 1950s bungalow in the Heights is not the same as the right system for a 3,000-square-foot two-story in Sugar Land, and we’ll explain the difference in plain English before you spend a dollar.
When You Need AC Installation
Not every cooling problem calls for AC replacement. But when the signs line up, delaying the decision usually just means paying high repair bills on a unit that’s already told you it’s done. Here’s what pushes Houston homeowners toward installation rather than another repair:
- Your system is more than 12 years old. Houston’s heat and humidity wear out compressors faster than in drier climates. A 14-year-old unit in Houston has often done the work of a 20-year-old unit in Denver. If your system was installed during the Bush administration, it’s on borrowed time.
- Your summer electric bills keep climbing. An aging AC loses efficiency every year. If your July and August bills have crept up 20% or more over three years without a change in your usage, the system is working harder to deliver the same cooling.
- You’ve had two or more repair calls in the last 24 months. A compressor replacement one summer, a condenser fan the next, a refrigerant leak after that. Each repair feels cheaper than replacement in the moment, but the math turns against you quickly. In Houston, we often see homeowners spend $1,800 to $2,600 on repairs in two years only to replace the system anyway.
- Some rooms stay hot no matter what. Uneven cooling is sometimes a ductwork issue, but it can also mean your system has lost capacity and can no longer push conditioned air to the far reaches of the house. A new unit won’t fix bad duct design, but if the ducts check out, the old system is the culprit.
- You’re still running an R-22 system. The older refrigerant known as Freon was phased out of new production years ago, and R-22 now costs $150 to $300 per pound in the Houston market. Recharging an R-22 system is a losing game, and a leak repair on one can easily hit $1,200 before labor. If your R-22 system is low, a new R-410A or R-32 system is the honest answer.
- You bought a house with an unknown-age AC. Home inspections catch a lot, but an old AC that cools on inspection day can limp through escrow and quit in August. If you just bought a home in Houston and the condenser looks like it’s been there since the previous owner moved in, have us check it before the first heat wave.
If you recognize your situation in that list, call (832) 371-9862. We’ll send a technician who will tell you honestly whether a repair buys you time or just delays the inevitable.
Our AC Installation Process
Every installation follows the same written sequence, the Kingswell Way: say the price before the work, show up in the window given, leave the place cleaner than we found it, put the guarantee in writing, and come back if anything goes wrong. Here’s how a typical Houston installation goes with us:
- In-home assessment and load calculation. We don’t quote a system size over the phone. A technician walks the house, measures each room, checks window exposure, inspects the ductwork, and runs a Manual J load calculation to determine exactly how many tons of cooling your home needs. In Houston’s humidity, an oversized system is nearly as bad as an undersized one because it short-cycles and never pulls moisture out of the air. You feel clammy even when the thermostat says 72.
- Written proposal with options and exact pricing. Before you decide anything, you get a written quote with the system size, SEER2 efficiency rating, brand, warranty terms, and total price. That price does not change at the door. We don’t do the “good news, bad news” routine where the final number lands higher than the quote.
- Scheduling with a firm arrival window. You pick the day, and we give you a window. When the crew rolls up, they’re in uniform, background-checked, and driving a marked Cold Harbour vehicle. You know exactly who’s walking through your door.
- Removal and installation. The old condenser and air handler come out, the new equipment goes in, the line set is connected, and the system is charged to manufacturer spec. We replace the filter, verify airflow, and check the drain pan and condensate line so you don’t get a ceiling stain in the first month. Work areas get drop cloths, and we clean up before we leave.
- Startup and walkthrough. We run the system through a full cool-down cycle, adjust the thermostat settings, and walk you through the new equipment. You’ll know where the filter goes, what the condensate drain does, and what your new thermostat controls are telling you.
- Written guarantee before we leave. Your installation comes with the manufacturer’s warranty on equipment, plus our written record of the work. If anything isn’t right, you call us. The Kingswell Guarantee doesn’t expire at the end of the driveway.
AC Installation Pricing in Houston
Houston AC installation prices land in a predictable range once you know the variables. Here’s what we see across the metro area in 2025:
| System Type | Typical Price Range (Installed) |
|---|---|
| 2-ton, 14 SEER2 single-stage AC with air handler | $4,800 – $6,300 |
| 3-ton, 16 SEER2 single-stage AC with air handler | $6,200 – $7,800 |
| 4-ton, 17 SEER2 two-stage AC with air handler | $7,900 – $9,600 |
| 5-ton, 18+ SEER2 variable-speed AC with air handler | $9,400 – $11,400 |
| Full replacement including new ductwork (whole home) | Add $3,500 – $6,500 depending on home size |
These ranges reflect the Houston market specifically. A 2,000-square-foot single-story in Pearland with accessible attic ductwork will land near the lower end. A 3,400-square-foot two-story in Memorial with original 1990s ducts and a tight mechanical closet will land higher. The variables are: home size, ductwork condition, equipment tier (single-stage vs. variable-speed), and site conditions like attic access or a condenser pad that needs rebuilding.
One thing that doesn’t vary is the written quote. The price we hand you before the work starts is the price you pay. If the crew discovers something unexpected during installation, we stop and talk to you before any change is made. No surprise line items at the end.
We also offer financing on approved credit, and we’ll walk through what the monthly payment looks like for different system tiers so you can decide based on total cost, not just sticker price. Call (832) 371-9862 for a free estimate. The quote is yours to keep either way.
FAQs – AC Installation
How much does AC installation cost in Houston?
AC Repair & Installation Near Me in Houston, TX typically costs between $4,800 and $11,400 for a complete system replacement, with most mid-size single-family homes falling in the $6,000 to $8,500 range depending on the equipment tier and ductwork condition. The final price depends on home size, SEER2 efficiency rating, brand, and site conditions. Call (832) 371-9862 for a free written estimate specific to your home.
How long does AC installation take in Houston?
Most AC installations take one full day, about 6 to 10 hours from arrival to final walkthrough, when the existing ductwork is in good condition. A job that includes ductwork replacement or major modifications can run two to three days. We give you a firm window at scheduling and we either hit it or call you before you have to call us.
Is it better to repair or replace my AC in Houston?
As a rule in the Houston market: if the repair costs more than 30% of the replacement cost and the system is over 10 years old, replacement is usually the smarter money. Houston’s cooling season runs nine months of the year, and the stress that puts on a system means a 12-year-old unit here is late into its lifespan. We’ll run the numbers with you honestly, not steer you to whichever option costs more today.
What brands do you install?
We install equipment from Carrier, Trane, and Lennox, and our technicians are trained to service all major residential brands including Goodman. If you have a brand preference or a system you’ve liked in the past, tell us in the assessment and we’ll price that equipment for you. The right answer is the system that fits your home and budget, not the one we happen to have the most margin on.
Can you install a new AC in Houston this week?
In most cases, yes. During the spring and fall shoulder seasons we can often schedule an installation within three to five business days. During a Houston July heat wave, emergency installations are available but scheduling tightens up, so call (832) 371-9862 as soon as you know you’re replacing. The phone is answered by a live person, 24 hours a day, every day of the year.
