HVAC replacement & upgrade in DFW
A 3-ton residential HVAC replacement in DFW costs between $5,200 and $14,500+, depending on efficiency rating and whether ductwork is rebuilt. TrueForm Remodeling's TDLR ACR-licensed HVAC division quotes three fixed-price tiers: a Replacement tier at $5.2K–$7.7K (14 SEER2 single-stage on existing ductwork), an Upgrade tier at $7.7K–$10.5K (16 SEER2 two-stage with R-32 refrigerant and a smart thermostat), and a Whole-Home Climate tier at $10.5K–$14.5K+ (variable-speed 18+ SEER2 with zoning, indoor air quality stack, and duct rebuild). Every install includes the permit, manufacturer registration in your name, and a 3-year workmanship warranty. We serve Dallas, Plano, Frisco, Southlake, McKinney, Allen, Richardson, Arlington, Carrollton, and Fort Worth.
Fixed-price tiers
Pricing reflects 2026 DFW market ranges for a typical 3-ton system in a ~2,000 sq ft home. Final price is set in writing after on-site load calculation and ductwork inspection.
| Tier | Price range | What's included |
|---|---|---|
| Good — Replacement | $5.2K–$7.7K | 14 SEER2 · single-stage · standard install · same ductwork |
| Better — System upgrade | $7.7K–$10.5K | 16 SEER2 · two-stage · R-32 refrigerant · smart thermostat |
| Best — Whole-home climate | $10.5K–$14.5K+ | Variable-speed · 18+ SEER2 · zoning · IAQ stack · duct rebuild |
What's included at each tier
Good — Replacement ($5.2K–$7.7K)
New 14 SEER2 single-stage condenser and matched coil from Goodman, Trane XR series, or Carrier Comfort. New line set if existing is damaged, new condensate pan, refrigerant evacuation and charge with R-32, new disconnect, and float switch. Existing ductwork stays. Standard pad on the condenser, basic programmable thermostat (or your existing if compatible). Permit pulled and inspection passed.
Better — System upgrade ($7.7K–$10.5K)
16 SEER2 two-stage condenser from Trane XL16i, Carrier Performance, or Lennox EL-series with matched variable-speed indoor blower. R-32 refrigerant. Smart thermostat (Ecobee Premium or Honeywell T10). New line set and pad. Mastic-sealed plenum and trunk-line connections, new return-air filter housing sized for a 4-inch MERV-13 media filter. UV light option at the coil.
Best — Whole-home climate ($10.5K–$14.5K+)
Variable-speed 18+ SEER2 inverter system from Trane XV20i, Carrier Infinity, or Lennox SL-series. Bypass or motorized-damper zoning for 2–4 zones with per-zone smart thermostats. Indoor air quality stack: MERV-13 media filter, UV-C coil light, whole-home dehumidifier (Aprilaire E100), and fresh-air ERV. Duct rebuild as needed — re-sized trunks, sealed boots, and balanced supply/return for the new equipment. Full manual J load calc and manual D duct design before install.

DFW-specific considerations
The R-32 refrigerant transition is the biggest 2026 change for DFW homeowners. The U.S. EPA AIM Act ended manufacturing of new R-410A residential equipment, so every new system ships with R-32 or R-454B. Existing R-410A systems are still serviceable, but a replacement is an R-32 install — new charge, not a top-off. Dallas, Plano, Frisco, McKinney, and Southlake all require a mechanical permit for full replacements; permit timing typically adds 3–5 business days. North Texas attic temperatures hit 140–150°F in July, which shortens equipment life on attic-installed air handlers — we add radiant barrier or relocate the air handler to conditioned space at the Better and Best tiers when feasible. Older Dallas homes (pre-1985) frequently have undersized return-air paths that throttle a modern variable-speed system; we resize returns as part of the duct rebuild.
Frequently asked
How much does HVAC replacement cost in DFW?
A 3-ton residential HVAC replacement in DFW (typical ~2,000 sq ft home) runs $5.2K–$7.7K for a 14 SEER2 single-stage on the existing ductwork, $7.7K–$10.5K for a 16 SEER2 two-stage with R-32 refrigerant and a smart thermostat, and $10.5K–$14.5K+ for a variable-speed 18+ SEER2 with zoning, IAQ add-ons, and duct rebuild.
What's the R-32 refrigerant transition and how does it affect my replacement?
The U.S. EPA AIM Act phased out R-410A for new residential HVAC manufacturing in 2026. New equipment ships with R-32 or R-454B, which are lower-GWP refrigerants. R-32 systems are slightly more efficient per ton but require a fresh evacuation and charge — not a top-off from an R-410A bottle. Existing R-410A systems remain serviceable for their useful life; replacement parts are still available.
Do I need a permit for HVAC replacement in Dallas or Plano?
Yes. Dallas, Plano, Frisco, McKinney, and most DFW municipalities require a mechanical permit for any complete system replacement. The permit covers the equipment swap, refrigerant lines, condensate, electrical disconnect, and the final inspection. We pull and close the permit and itemize the fee in your written scope.
What SEER2 rating should I pick for a DFW home?
DFW summer load makes 16 SEER2 the practical sweet spot for most homes — the efficiency gain over 14 SEER2 pays back within 5–7 years given Texas cooling hours. Variable-speed 18+ SEER2 is worth the upgrade if you want quieter operation, better humidity control during the May–June shoulder season, or zoning. The U.S. minimum has been 14.3 SEER2 (Southern region) since January 2023.
How long does an HVAC replacement install take?
A straight equipment swap on existing ductwork is a one-day install. Adding a smart thermostat, IAQ accessories, or new line sets adds half a day. A full zoning + duct rebuild is 2–4 days. We schedule equipment delivery ahead of the install date so the home isn't without cooling longer than necessary.
Are you TDLR ACR-licensed?
Yes. All HVAC replacement work is performed under a Texas Department of Licensing and Regulation Air Conditioning and Refrigeration (TDLR ACR) license. The license number appears on the permit application and the project paperwork. We also carry general liability and workers' comp on every install.
Do you offer maintenance plans for the new system?
Yes. TrueForm Home Care includes HVAC tune-ups at every tier — 2 visits per year on Essential, full spring and fall tune-ups on Plus, and monthly visits on Premier. Plan members get priority scheduling on repairs and a discount on parts and labor. Plans start at $19/month.
