AfterAC Replacement in Houston, TX
AC replacement in Houston typically runs $6,500 to $14,500 for a complete system swap, depending on home size, efficiency rating, and ductwork condition. Most replacements take one full day, and we start by sizing the new unit to your home’s actual cooling load rather than just swapping in whatever was there before. If your current system is struggling through Houston summers, it’s worth a close look at whether repair money is better spent toward a new unit. Our AC Repair & Installation team handles replacements across the city, and you can reach us anytime at (832) 371-9862.
Victor Mancini has run Cold Harbour Heating and Air Houston since 2003, and he’s handled enough Compressor Repair jobs and rusted-out condenser coils to know when a repair is just buying time. We’ll tell you straight if a replacement makes more sense, and we’ll put the price in writing before the first tool comes off the truck.
When You Need AC Replacement
Some systems give you a season of warning signs. Others fail outright in the middle of a 98-degree afternoon. Either way, here’s what we see most often in Houston homes:
- Your system is 12 to 15 years old and the compressor has failed. A compressor replacement can run $2,000 to $3,500 on an aging unit. On a system that old, that money is often half the cost of a new, warrantied unit with modern efficiency.
- You’re recharging refrigerant every spring. R-22 (Freon) systems are increasingly expensive to top off as supply phases out. If your system leaks, the leak needs to be found, not just topped off. On older equipment, converting or replacing is usually the better long-term move.
- Humidity control has gotten worse. Houston’s humidity is relentless, and an aging or oversized system often can’t pull moisture out of the air like it used to. Newer two-stage and variable-speed units run longer at lower output, which dehumidifies better than a worn-out single-stage blasting cold air in short bursts.
- Energy bills keep climbing while cooling stays weak. A 10-SEER system from 2005 uses roughly 40% more electricity than a modern 16-SEER unit to produce the same cooling. In Houston, where AC runs from March through November, that difference adds up fast.
- Repairs are becoming a monthly occurrence. If you’ve spent more than $500 on parts in the past 12 months, or had two different breakdowns in one season, the equipment is telling you something.
- The indoor coil or heat exchanger has failed. On a system over 10 years old, a failed evaporator coil is a big-ticket repair that often doesn’t make financial sense against replacement.
Our AC Replacement Process
We follow a set process on every replacement, so you know exactly what’s happening from the first call to the final walkthrough.
- Call and talk to a real person. A live person answers 24/7. You’ll describe the problem, and we’ll schedule a visit with a firm arrival window, not a four-hour “sometime between” block.
- Home assessment and load calculation. A background-checked, uniformed technician visits your home, inspects the existing system and ductwork, and runs a proper load calculation based on square footage, insulation, window orientation, and ceiling height. This is how we avoid oversizing, which is a common cause of humidity problems in Houston homes.
- Written quote with clear options. Before any work begins, you get a written price with system options at different efficiency levels. We explain the trade terms in plain English: SEER ratings, single-stage versus two-stage, and what each choice means for your monthly bill.
- Installation day. We remove the old equipment, set the new condenser and air handler or coil, connect the refrigerant lines, and check airflow throughout the house. Most replacements are done in one day. We put down drop cloths and clean up as we work.
- System startup and walkthrough. We test the system in both cooling and fan-only modes, measure the temperature drop at the supply and return, and walk you through your new thermostat settings. You’ll get the 365-Day Done Right Promise in writing before we leave.
- Follow-up. If anything isn’t right within the first year, we come back and fix it at no charge. That’s not a verbal promise. It’s on paper.
AC Replacement Pricing in Houston
Here’s what a full system replacement typically costs in Houston, based on the jobs we do across the metro area:
| System Type | Typical Houston Price Range |
|---|---|
| 14-SEER single-stage AC, 3-ton, with coil | $6,500 – $8,500 |
| 16-SEER single-stage AC, 3-ton, with coil | $7,500 – $10,000 |
| 17-SEER two-stage AC, 4-ton, with coil | $10,000 – $13,000 |
| 20-SEER variable-speed AC, 4-ton, with coil | $12,000 – $14,500 |
| Full system with furnace (heat pump or gas) | $9,000 – $16,000 |
Several factors move the final number. Ductwork condition matters: older homes in neighborhoods like Meyerland or Timbergrove sometimes need major duct sealing or replacement, which adds $2,000 to $6,000. Access to the attic, the condition of the electrical disconnect, and whether the line set can be reused all play a role. We inspect all of this during the assessment and include it in the written quote. You’ll never get a door-price bump from us. The Kingswell Way is simple: say the price before the work, show up in the window given, leave the place cleaner than found, put the guarantee in writing, and come back if it fails.
We carry and service Carrier, Trane, and Lennox systems, and our technicians are trained on all major residential brands, so the unit we install will be one we know how to maintain for its full life. Every estimate is free, and every replacement includes the written 365-Day Done Right Promise. Call (832) 371-9862 to schedule an assessment.
AC Replacement vs. Repair: What Makes Sense?
The standard rule of thumb is this: multiply the age of the system by the repair cost. If that number exceeds $5,000, replacement is usually the smarter long-term choice. A $400 repair on an 8-year-old system is a fine investment. A $1,800 repair on a 14-year-old system is riskier, because you’re one more breakdown away from having spent half the cost of a new unit on a machine that’s already past its expected life.
In Houston, the math is further tilted by the climate. Our AC systems run harder and longer than systems almost anywhere else in the country. A 15-year-old Houston AC has done more total work than a 20-year-old unit in a milder climate. That’s why a rusted-out condenser coil in Katy or a failed compressor in Spring often pushes us to recommend our ac repair installation services for replacement sooner than you might expect.
If your system is under 8 years old and the failure is an inexpensive part like a Capacitor Replacement or a contactor, repair is generally the right call. We’ve rebuilt many systems in inner-loop bungalows and outer-suburb tract homes that had years of honest life left. We’ll give you the straight answer either way.
FAQs – AC Replacement
How much does AC replacement cost in Houston?
Most full AC replacements in Houston run between $6,500 and $14,500, installed, depending on system size, SEER rating, and whether ductwork needs attention. A standard 16-SEER, 3-ton system with a new coil typically falls between $7,500 and $10,000. Call (832) 371-9862 for an exact quote, free of charge.
How long does AC replacement take?
A straightforward AC replacement takes one full day. We arrive in the morning, remove the old equipment, set the new condenser and coil, connect the lines, and run the system through a full startup test before we leave. If ductwork needs work, the job may run into a second day, and we’ll tell you that up front.
Can you replace my AC the same week I call?
In most cases, yes. During peak Houston summer months, our schedule tightens, but we hold a firm arrival window and don’t overbook. If your AC has failed entirely, call us and we’ll get you on the schedule as quickly as possible. A live person answers 24/7.
What does the 365-Day Done Right Promise cover?
Every AC replacement and Refrigerant Recharge or other repair we do is covered in writing for 365 days. If the work fails within that year, we come back and make it right at no charge. The guarantee is printed and handed to you before the technician leaves, not buried in a terms page.
Do you offer financing for AC replacement?
Yes. We work with several financing providers, and your technician can walk you through the options during the assessment. The written price doesn’t change based on how you pay.
What brands do you install?
We install Carrier, Trane, Lennox, and Goodman equipment, and our techs are trained to service all nine major residential brands. We’ll recommend the unit that fits your home’s cooling load and your budget, not whatever is overstocked in the warehouse.
