AfterAC Replacement in Dallas, TX
Air conditioning replacement in Dallas typically runs $4,500 to $9,800 for a standard single-family home, depending on the size of the system, the efficiency rating you choose, and whether your ductwork needs work. Most replacements take one to two days from tear-out to a running, tested system. At Brandt HVAC Co Dallas, we give you a written price before any work starts, so you know the full number before you ever commit. Call us at (325) 312-3269 and we’ll walk you through what makes sense for your house.
AC replacement is a bigger decision than a repair, and it’s one that Dallas homeowners face more often than most. Our summers push systems hard for months at a time, and a unit that’s near the end of its life tends to give up somewhere around mid-July, right when you need it most. This page explains when replacement is the right call, what it costs here, and exactly how Brandt HVAC Co Dallas handles the job from first phone call to final test. It’s a companion to our broader AC Repair & Installation work, and you’ll find the same rules apply: named technician before arrival, written price before any labor, and a written guarantee on every job.
When You Need AC Replacement
Not every broken air conditioner needs to be replaced. A skilled technician can often get more years out of a system with the right repair. But there are times when replacement is the honest recommendation. Here’s what pushes us in that direction:
- Your system is 12 to 15 years old, or older. In Dallas, a residential AC works hard enough that most units fade out between year 12 and year 15. Once you’re in that range and facing a major repair, the math starts leaning toward replacement.
- The compressor has failed. This is the heart of the system. On an older unit, a compressor replacement can cost more than half the price of a new system, and you’re still left with aging components around it.
- You’re recharging refrigerant repeatedly. If your system leaks refrigerant and you’re refilling it every season, that fluid is getting expensive. R-410A prices have climbed steadily, and older R-22 systems are simply not worth feeding anymore.
- Your energy bills keep climbing while comfort drops. A fading system runs longer and harder to hit the same temperature. That shows up on your bill and in rooms that never quite cool down.
- Rooms are uneven, humid, or never reach the set temperature. Sometimes the unit is simply undersized for the home, or the ductwork has quietly deteriorated. Replacement lets us correct sizing and airflow at the same time.
- Repairs are stacking up. One $300 fix here, another $500 fix there. If you’ve spent a couple thousand dollars over the last two summers and the unit is still struggling, a new system resets the clock.
We’ll never push a replacement when a repair is the smarter, cheaper move. If a fix will give you real years of service, we’ll say so plainly. When we do recommend replacement, we’ll show you the numbers that back it up.
Our AC Replacement Process
Here’s how a replacement works when you work with Brandt HVAC Co Dallas:
- You call, and a live person answers. Day or night, weekends included, there’s no phone tree and no voicemail. We’ll schedule a time that fits your life, and we’ll tell you exactly who is coming.
- You get the technician’s name and photo before they arrive. Every Brandt HVAC Co Dallas technician is background-checked and identity-verified under the Threshold Verified standard. Before your appointment, we send you their name and picture. At the door, they show you their photo ID badge. If anyone shows up who you weren’t told to expect, that visit is on us, and we make it right.
- We inspect your current system and your home. We don’t just quote a new unit off a spec sheet. We look at your existing equipment, check your ductwork and insulation, and measure your space. A system that’s too big or too small costs you comfort and money for years. We size it correctly.
- You get a written price before any work starts. No exceptions, no handshake estimates. The equipment, the labor, the removal of the old unit, the startup testing: it’s all on paper. You see and approve the number before we touch a single screw.
- We install, test, and walk you through it. The old system comes out, the new one goes in, and then we test it thoroughly. You’ll see how to use your new thermostat and understand exactly what the written guarantee covers and for how long.
- The 365-Day Done Right Promise follows you. If it’s not done right, we make it right. If the repair or installation fails within the guarantee period, we come back at no charge. No argument, no fine print.
AC Replacement Pricing in Dallas
Here’s what you can expect to invest for a full AC replacement in the Dallas market, based on typical single-family homes and current 2025-2026 equipment and labor pricing:
- Basic 14-15 SEER2 system, 2.5-3 ton: $4,500 to $6,800 installed
- Mid-range 16-17 SEER2 system, 3-4 ton: $6,800 to $8,900 installed
- High-efficiency 18-20+ SEER2 system, variable speed: $8,900 to $12,500+ installed
- Full system with new ductwork or major duct repairs: add $2,000 to $6,000 depending on scope
- Thermostat upgrade (smart thermostat): $150 to $450 installed
What moves the price most is the size of the system, the efficiency tier, and whether your ductwork is sound. A 900-square-foot condo and a 3,000-square-foot two-story home need very different equipment. Two-stage and variable-speed systems cost more up front but cut electrical use every month, which matters in Dallas, where the AC runs from April to October.
Brandt HVAC Co Dallas services equipment from Trane, Lennox, Goodman, and Rheem, among other major brands. The right brand for your home depends on your budget, your comfort goals, and what’s compatible with your current setup. We’ll explain the differences in plain language, with no pressure toward any single label.
Every quote is a written quote. You’ll see the full number before you approve anything. And for an exact figure on your house, call (325) 312-3269 and we’ll schedule a free estimate. No obligation, no surprise charges.

FAQs – AC Replacement
Is it cheaper to repair or replace my AC?
For a system under 10 years old with a clear, isolated failure, repair is almost always the cheaper short-term play. The tipping point comes when the system is over 12 years old and the repair bill exceeds roughly a third of the cost of a new unit. A $1,800 compressor replacement on a 14-year-old system is money that would be better spent on new equipment. We’ll walk you through the math on your specific unit before you decide anything. Call (325) 312-3269 for a straight answer on your system.
How much does AC replacement cost in Dallas?
Most Dallas homes fall between $4,500 and $9,800 for a full AC replacement, installed. Small condos and townhomes can land closer to $4,000, while large homes with high-efficiency equipment and new ductwork can exceed $12,000. Your exact number depends on system size, efficiency rating, brand, and ductwork condition. We provide a free estimate with a written price before any work begins.
Can you replace my AC the same week?
In most cases, yes. We keep common system sizes in stock for the brands we service, including Trane, Lennox, Goodman, and Rheem. If your size and configuration are standard, we can often schedule installation within a few days of your estimate. If you’re without AC entirely, call (325) 312-3269 and we’ll let you know the soonest we can get a crew to you.
What does your AC replacement guarantee cover?
Every AC replacement from Brandt HVAC Co Dallas includes a written guarantee on parts and labor.

The specific term of the guarantee is written on your quote and your final paperwork, so you always know exactly what’s covered and for how long. No verbal promises, no ambiguity.
