The A/C Techs Air & Heat LLC installs and replaces residential central air conditioning systems across the Dallas-Fort Worth metroplex. An AC installation is a long-term decision — the equipment you pick today will run 12–17 Texas summers. We help you choose the right size, the right efficiency level, and the right brand for your budget, then install it the right way the first time.

Quick answerA complete residential AC replacement in the DFW area typically costs $6,700–$12,000, with the unit itself running $3,700–$7,400 and installation adding $3,000–$5,000. Ductwork modifications add $2,500–$8,000 when needed. A properly sized, correctly installed system will cut your summer electric bills 20–35% vs. an aging single-stage unit.

How Much Does a New AC Cost in Dallas?

Typical installed prices in the DFW market, based on system size (tons) and efficiency (SEER2):

  • 1.5-ton system (small home, up to ~900 sq ft) — $5,000–$8,000 installed
  • 2-ton system (~900–1,400 sq ft) — $5,500–$9,500 installed
  • 2.5-ton system (~1,400–1,800 sq ft) — $6,000–$10,500 installed
  • 3-ton system (~1,800–2,200 sq ft) — $6,500–$11,500 installed
  • 4-ton system (~2,200–2,800 sq ft) — $7,500–$13,000 installed
  • 5-ton system (~2,800–3,500 sq ft) — $8,000–$14,500 installed

Add $2,500–$8,000 for duct replacement or significant duct modifications. Add $1,500–$3,500 for a matched gas furnace or air handler if you're replacing the whole system. High-efficiency (17+ SEER2) two-stage and variable-speed systems cost 15–30% more up front but can pay back the difference in 5–8 summers through lower electric bills.

How Do You Know What Size AC I Need?

We perform a Manual J load calculation — the industry-standard method for sizing residential HVAC equipment. Manual J accounts for your home's square footage, ceiling height, window count and orientation, insulation values, duct condition, and shading. It's the opposite of the shortcut some companies still use ("you have a 3-ton, so we'll put in a 3-ton"), which is how DFW homes end up with oversized systems that short-cycle, fail early, and leave humidity problems behind.

Rule of thumb in Texas: 1 ton of cooling per 500–600 square feet of living space — but the real number depends on your specific home. A shaded 1960s ranch with good insulation may need less; a sun-blasted 2000s two-story with vaulted ceilings may need more.

Which AC Brands Hold Up Best in Texas Heat?

The top-performing residential AC brands in North Texas, based on reliability, parts availability, and warranty coverage:

  • Trane (XV-series) — legendary durability, strong 10-year parts warranty
  • Carrier (Infinity series) — excellent variable-speed performance and humidity control
  • Lennox (XC-series) — highest available SEER ratings, strong dealer network
  • Rheem / Ruud (Prestige) — solid mid-tier value, often 20% less than Trane/Carrier
  • Bryant — Carrier's sister brand; identical engineering, friendlier pricing
  • Goodman / Amana — budget-friendly; good warranties; simpler tech that's easier to service long-term

Honest truth: brand matters less than installation quality. A properly-installed Goodman will outlast a poorly-installed Trane. We'll walk you through three brand/efficiency options at different price points and let you pick.

SEER2 vs. SEER — What Should I Buy?

SEER2 is the current federal efficiency rating (replaced SEER in January 2023). Higher SEER2 = lower electric bills. In the DFW climate zone, the minimum SEER2 for new installs is 14.3. Practical efficiency tiers:

  • 14–15 SEER2 (entry-level) — lowest up-front cost, works fine for smaller homes
  • 16–17 SEER2 (mid-tier) — the sweet spot for most DFW homes; 15–25% bill savings vs. a 10-year-old 13 SEER unit
  • 18–20 SEER2 (high-efficiency) — two-stage or variable-speed; best humidity control and comfort; 25–40% bill savings
  • 21+ SEER2 (premium) — variable-speed only; usually overkill unless you're in a very large or glass-heavy home

How Long Does a New AC Installation Take?

A straightforward same-footprint replacement (same size, same refrigerant lines, no ductwork changes) is a one-day job — typically 6–9 hours from arrival to cleanup. Jobs that include ductwork modifications, attic air handler swaps, or zoning upgrades run 1.5–3 days. Full gut-and-replace jobs with new ductwork can be 3–5 days.

We always protect your home with drop cloths, carry the old equipment out the way we brought it in, and test every temperature, pressure, and airflow reading before we leave.

What's Included in Your Installation Quote?

  • Equipment (condenser, evaporator coil, furnace/air handler as needed)
  • New refrigerant lines and service valves
  • New thermostat (smart thermostat if you want one)
  • New condensate drain line and safety float switch
  • New electrical disconnect and whip
  • Evacuation and factory-spec refrigerant charge
  • Full system commissioning: static pressure, airflow, superheat/subcool
  • Manufacturer parts warranty (typically 10 years) and our workmanship warranty
  • Permit fees and inspection coordination where applicable

If a quote from another company comes in much lower, check whether it includes the items above. Skipping commissioning, permit fees, or a float switch is how you get a cheap install that fails in three summers.

FAQ

Frequently Asked Questions

How much does a new AC installation cost in Dallas?
A complete residential AC installation in the Dallas-Fort Worth metroplex typically costs $6,700–$12,000 for the full system. The equipment itself runs $3,700–$7,400 depending on size and efficiency, and installation adds $3,000–$5,000. New ductwork, if needed, adds $2,500–$8,000. Higher-efficiency systems (18+ SEER2) cost more up front but cut electric bills 25–40%.
How do I know what size AC I need?
We perform a Manual J load calculation — the industry-standard method that accounts for square footage, ceiling height, insulation, window count, duct condition, and shading. As a rough guide, Texas homes need about 1 ton of cooling per 500–600 square feet, but the actual number depends on your home. Oversized systems short-cycle, wear out faster, and leave humidity behind.
What is the best AC brand for Texas heat?
Trane, Carrier, Lennox, Rheem, Bryant, and Goodman all hold up well in DFW. Trane and Carrier's premium lines (Trane XV20i, Carrier Infinity 21) lead on reliability and efficiency. Rheem and Goodman offer excellent value at 15–25% less. Honestly, brand matters less than installation quality — a properly-installed Goodman will outlast a sloppy Trane install.
What is SEER2 and what rating should I buy?
SEER2 is the current federal efficiency rating that replaced SEER in January 2023. The minimum allowed in DFW is 14.3 SEER2. For most homes, 16–17 SEER2 is the sweet spot — it cuts bills 15–25% vs. an old 13 SEER unit without the premium cost of variable-speed equipment. 18–20 SEER2 makes sense for larger or humidity-sensitive homes.
How long does AC installation take?
A straightforward same-size replacement with no ductwork changes is typically a one-day job, about 6–9 hours. Installations with ductwork modifications or attic air handler swaps take 1.5–3 days. Full gut-and-replace jobs with new ductwork run 3–5 days.
Do I need new ductwork when I replace my AC?
Not always. If your existing ducts are sealed, properly sized, and in good condition, we can reuse them. Common reasons to modify or replace ducts include undersized returns (very common in 1970s–1990s homes), leaky fiberglass ductboard, crushed flex runs in the attic, or a significant size change between the old and new system. We inspect and test the ducts before recommending changes.
Should I replace just the outside unit or the whole system?
Almost always the whole system. Modern outside units (condensers) are matched to specific indoor coils and refrigerant metering devices. Mixing an old indoor coil with a new outside unit voids most manufacturer warranties, loses 10–20% of the rated efficiency, and often leads to premature compressor failure. Replace both halves together.
Is a heat pump or straight AC better for North Texas?
Heat pumps make excellent sense in DFW because our winters are mild. A single heat pump handles both cooling and heating, and modern heat pumps stay efficient down to the low 30s — which covers most DFW winter days. Pair a heat pump with electric heat strips or a small gas furnace for the occasional hard freeze and you get lower energy bills year-round.
What warranty comes with a new AC installation?
All major brands include a 10-year parts warranty when registered within 60–90 days of installation. Compressors often carry a separate 10- or 12-year warranty. Labor warranties vary by contractor — ours is in writing and clearly spelled out in every quote. If the paperwork isn't transparent, walk away.
Do you handle AC installation permits and inspections?
Yes. We pull the required mechanical permits with the city and coordinate the inspection. Skipping permits is a red flag — unpermitted HVAC work can void your homeowner's insurance and block future home sales. The permit fee is disclosed in your quote.
