AfterAC Replacement in Dallas, TX
AC replacement in Dallas typically costs between $6,500 and $14,500 for a full system swap, depending on home size, efficiency rating, and ductwork condition. Most homeowners in Dallas replace an air conditioner when the repair bill crosses half the cost of a new unit, or when the system is over 12 years old and leaking refrigerant. Cold Harbour Heating and Air Dallas walks every customer through the numbers before the work starts, so there’s no guessing at the door.
We’ve been replacing air conditioners across Dallas since 2003, and the job hasn’t changed much: get the sizing right, pull the old unit cleanly, set the new one on a level pad, and leave the house cooler than we found it. The difference is that we put the price in writing before a single tool comes out of the truck, and every replacement carries the 365-Day Done Right Promise. If anything we installed fails inside a year, we come back and correct it at no charge. That’s not a verbal promise. It’s on paper.

When You Need AC Replacement
Not every struggling air conditioner needs to be replaced. Some need a capacitor, a contactor, or a refrigerant recharge (topping off the cooling fluid your AC needs to run). But there are moments when replacement is the honest answer, and we’d rather tell you that on the front end than sell you a repair that won’t hold through a Dallas August. Here’s what pushes a system into replacement territory:
- Your AC is over 12 years old and the compressor fails. The compressor is the heart of the system. On a unit that age, a compressor replacement can run $2,000 to $3,500, which is money better spent toward a new system with a fresh warranty.
- The system uses R-22 refrigerant. R-22 was phased out years ago, and the remaining supply is scarce in Dallas. Recharging an R-22 system now costs more than the recharge is worth, and the price keeps climbing. Replacement moves you to R-410A or newer refrigerant.
- Your energy bills keep rising in the summer. Older systems in Dallas neighborhoods like Lake Highlands, Preston Hollow, and Oak Cliff lose efficiency every year. A 10-SEER unit from 2005 can cost nearly twice as much to run as a modern 16-SEER unit.
- Repairs are stacking up. If you’ve spent $800 here and $600 there over the last two years, the math says stop. A good rule: multiply the age of the system by the repair cost. If that number exceeds $5,000, replacement is the smarter move.
- Uneven cooling between rooms. This can be a duct issue, but in many older Dallas homes it means the system was undersized from the start or has lost capacity. Replacement with a properly sized unit fixes the hot spots.
- The indoor coil or evaporator is leaking. A coil replacement on an aging system is often $1,500 to $3,000, and you’re still left with an old compressor and outdoor unit. Customers in Carrollton and Richardson ask us about this exact scenario every summer.
Key Takeaways
- Full AC replacement in Dallas runs $6,500 to $14,500 installed.
- Replacement makes sense when your system is 12+ years old, uses R-22, or needs a major repair over $2,000.
- Cold Harbour Heating and Air Dallas gives a written price before work begins, every time.
- Every replacement is backed by a 365-Day Done Right Promise in writing.

Our AC Replacement Process
A replacement is a bigger job than a repair, and the process should be predictable. Here’s how we handle every AC replacement in Dallas:
- Free in-home walkthrough and load calculation. A technician measures the square footage, checks window orientation, inspects the ductwork, and looks at insulation levels. We don’t guess at tonnage. A 3-ton unit in a 2,200-square-foot house might be right in Plano and wrong in a 1980s build in East Dallas with old windows. The calculation tells us.
- Written proposal with the equipment quote you’ll actually pay. Before any work begins, you get a line-item price in writing. Equipment, labor, removal, city permit, startup and testing. The price does not change at the door. This is one of the five values of The Kingswell Way: say the price before the work.
- Scheduled installation with a firm arrival window. We give you a specific window, not “sometime Tuesday.” The team shows up when we say we will. The name Cold Harbour comes from a roadside shelter where travelers waited out the weather; our job is comfort in any season, and that starts with showing up.
- Removal and installation by background-checked, uniformed technicians. We pull the old condenser and air handler, set the new equipment on a level pad outside and a stable platform inside, run the line set, and connect the electrical. Our techs are trained on nine major residential HVAC brands including Trane, Lennox, Goodman, and Rheem, so the work is clean regardless of what was in the home before.
- Startup, testing, and a clean job site. We charge the system, verify airflow and temperature drop across the coil, cycle it through heating and cooling, and check the drain line. Then we sweep, vacuum, and haul off every scrap. The Kingswell Way says leave the place cleaner than we found it.
- Written guarantee handed to you before we leave. The 365-Day Done Right Promise is not an email. It’s a physical document outlining exactly what’s covered and for how long. If the replacement fails within 365 days, we return and correct the work at no additional charge.
AC Replacement Pricing in Dallas
What you’ll pay for an AC replacement in Dallas depends on four things: the size of the unit, the efficiency rating, the brand, and whether the ductwork needs attention. Here’s what most Dallas homeowners see, based on the work we’ve performed since 2003:
| Scenario | Typical Range | Notes |
|---|---|---|
| Basic 14-SEER, 3-ton replacement | $6,500 – $8,500 | Single-stage cooling, existing ductwork in good shape |
| Mid-range 16-SEER, 3.5-ton replacement | $8,500 – $11,000 | Two-stage cooling, better humidity control |
| High-efficiency 18-SEER+, 4-ton replacement | $11,000 – $14,500 | Variable-speed, quietest operation, highest energy savings |
| Replacement plus ductwork repair or modification | +$1,500 – $4,500 | Depending on scope: sealing, insulation, partial replacement |
Brand matters too. Goodman tends to come in lower on installed price while still carrying a solid warranty. Rheem, Lennox, and Trane sit in the mid-to-upper range with strong reliability records in the Dallas heat. We’ll quote whatever you prefer and explain the trade-offs without pushing a single brand. We service all major residential brands and install the system that fits your budget and your home.
Efficiency is worth considering seriously in Dallas. Our cooling season runs roughly April through October, and a jump from 14-SEER to 16-SEER can cut your summer cooling costs by 10 to 12 percent. Over a 15-year system life in a Dallas home, that’s thousands of dollars. It may justify a slightly higher upfront price.
Every estimate is free, and every estimate comes in writing before work begins. Call (430) 213-5796 to schedule a walkthrough. We’ll measure, calculate, and give you a real number, no obligation.
FAQs – AC Replacement
Is it cheaper to repair or replace my AC in Dallas?
There’s a simple test we recommend: multiply the age of your air conditioner by the cost of the repair. If that number is over $5,000, replacement is almost always the better financial move in Dallas. On a 10-year-old system, that means a $500 repair still favors repair. On a 14-year-old system, the same $500 repair leans toward replacement. We’ll walk you through the numbers on your specific unit during the free estimate. Call (430) 213-5796 and we’ll help you do the math.
How long does an AC replacement take in Dallas?
A straightforward AC replacement in Dallas takes one full day, typically 6 to 10 hours for a team of two or three technicians. If ductwork modification or a new line set through a slab is involved, it can run into a second day. We’ll tell you the exact timeline on the written proposal before you commit. We give a firm arrival window, and our team shows up when we say we will.
Can you replace my AC the same day I call?
Sometimes yes, but most Dallas replacements are scheduled within 3 to 7 days so we can pull the correct equipment and any needed permits. If your system has failed completely during a heat wave, call (430) 213-5796 and we’ll do what we can. We keep common condenser and air handler combinations available locally, and emergency installs happen, especially during Dallas summer heat spikes.
What guarantee comes with a Dallas AC replacement from Cold Harbour?
Your new AC is covered by the manufacturer’s parts warranty, typically 10 years on the compressor when registered, plus the 365-Day Done Right Promise from Cold Harbour Heating and Air Dallas. That promise is written down before we leave: if any part of our installation fails within 365 days, we return and correct it at no charge. Free second visit. No argument.
