The Honest Answer on AC Replacement Costs
I'm Omar Jacobo, owner of Frosty's HVAC, and I'm going to give you the real numbers on what AC replacement costs in Texas in 2026. Not the vague "it depends" answer you get from most contractors — actual price ranges with real context.
I've installed hundreds of AC systems across Farmers Branch, Coppell, Irving, Flower Mound, Lewisville, and Grapevine since 2018. The prices below reflect what homeowners in our service area actually pay, including equipment, labor, permits, and disposal of the old unit.
2026 AC Replacement Price Tiers
At Frosty's HVAC, we've organized our pricing into three clear tiers so you can find the right balance between budget and features:
Stay Cool (Value Tier): $8,000–$14,000
This is a quality, no-frills replacement using a 15 SEER2 system from Goodman. You get a reliable, energy-efficient system with a manufacturer warranty (typically 10 years on parts). This tier is perfect for homeowners who need a dependable system without premium features. Most homes in Farmers Branch and Irving fall into this range for a standard 3-ton replacement.
Stay Frosty (Mid Tier — MOST POPULAR): $12,000–$18,000
This tier steps up to 18 SEER2 equipment from Carrier with a dual-stage compressor. What does that mean for you? Quieter operation, better humidity control, and more even temperatures throughout your home. If you have a two-story home in Flower Mound or Coppell where the upstairs is always hotter, this tier makes a real difference. You'll also see lower energy bills — typically $30–$50 less per month in summer compared to a basic system.
It's A Frosty Life (Premium Tier): $16,000–$20,000+
This is top-of-the-line: a 20+ SEER2 inverter-driven Trane system that adjusts its output continuously rather than cycling on and off. These systems are whisper-quiet, incredibly efficient, and maintain your set temperature within 1°F. If you work from home, have a large house in Lakeside or Castle Hills, or just want the lowest possible energy bills, this tier pays for itself over time through energy savings that can exceed $100/month compared to an older system.
What Affects Your Specific Price?
Within each tier, your actual cost depends on several factors specific to your home:
- System size (tonnage): A 2-ton system for a 1,200 sq ft home costs less than a 5-ton system for a 3,500 sq ft home. We determine the right size through a Manual J load calculation — not guesswork.
- Ductwork condition: If your existing ductwork is in good shape, we can reuse it. If it's leaking, kinked, or undersized, we'll recommend modifications that add $500–$2,000 to the project.
- Electrical upgrades: Some older homes in Irving and Farmers Branch need a disconnect upgrade or new wiring to the outdoor unit. This is typically $200–$500 if needed.
- Thermostat upgrade: We include a basic programmable thermostat. Upgrading to a WiFi smart thermostat (Nest, Ecobee) adds $150–$250.
- Refrigerant line set: If we need to run new copper lines between the indoor and outdoor units (common when relocating equipment), that adds $300–$800.
How Texas Climate Affects Your Decision
Here's something most contractors won't tell you: in Texas, your AC system works harder than almost anywhere else in the country. We regularly hit 100°F+ for weeks straight in July and August, and your system runs 12–16 hours a day during peak summer. That means two things:
- Efficiency matters more here. The difference between a 15 SEER2 and an 18 SEER2 system in Texas can be $400–$700 per year in electricity. Over 15 years, that's $6,000–$10,500 in savings — which often covers the price difference between tiers.
- Quality installation matters more here. A poorly installed system in a mild climate might still work okay. In Texas's extreme heat, improper refrigerant charge, oversized equipment, or leaky ductwork will cause premature failure. This is why we're meticulous about load calculations and installation quality.
Financing Makes It Affordable
Most homeowners don't pay for AC replacement out of pocket. We offer flexible financing options that can put a new system in your home for $80–$180/month depending on the tier and term. Many homeowners find that the monthly payment is partially offset by the reduction in their electric bill — especially when replacing a 15+ year-old system with a high-efficiency unit.

The Bottom Line
AC replacement in Texas in 2026 costs between $8,000 and $20,000 depending on the system you choose and your home's specific requirements. The best value isn't always the cheapest system — it's the one that's properly sized, professionally installed, and efficient enough to pay you back through lower energy bills over its 15–20 year lifespan. That's what we deliver at Frosty's HVAC, and that's why 94 homeowners have given us a 4.9/5 rating on Google.
