AC Replacement Cost in DFW (2026): Real Numbers From a Local Pro

If your AC is on its last legs, the first thing you want to know is what a new one costs. The problem is that most answers online are national averages, and national averages were not built for a North Texas attic in August.

Here is what we see in Dallas-Fort Worth, what drives the number up or down, and how to tell a fair quote from a padded one.

The short answer

A complete 16 SEER2 system replacement in DFW is commonly quoted between $6,500 and $13,000. That is a wide range, and it is wide for real reasons, which we cover below.

Lantern prices a replacement differently from most quotes you will see. You pay the wholesale cost of the equipment plus labor starting at $1,850, and the quote shows both numbers on separate lines. You see exactly what the system costs and exactly what the installation costs.

What moves the price

The size of the system

Bigger systems cost more, but bigger is not better. An oversized AC cools the air fast, shuts off before it pulls the humidity out, and wears itself out cycling on and off. The only reliable way to size a system is a load calculation for your actual house. We explain why in what size AC do I need.

Efficiency

Every new split system installed in Texas has to meet a federal efficiency floor, and higher efficiency equipment costs more up front and less to run. Whether the upgrade pays for itself depends on how long you plan to stay and how hard your system works each summer.

Ductwork

A new system on old, leaking ductwork is like a new engine on flat tires. If the ducts are crushed, disconnected, or badly sized, the quote should say so. Duct repair is often where two quotes for the “same” system end up thousands of dollars apart.

Where the equipment lives

Many DFW homes have the indoor unit in the attic. Attic installs take more time and care, especially in summer, and the drain pan and float switch under that unit matter more than most people realize. We saw why on an attic drain job where the pan was one overflow away from a ceiling repair.

Refrigerant

Older systems run on R-410A, which is being phased down. New equipment uses newer refrigerants. That affects both the price of repairs on an old system and the case for replacing it. Our repair or replace guide covers it.

Permits

Permits in DFW are handled city by city, and each city runs its own inspections. Ask whether your replacement needs one in your city and whether the quote includes it. A quote that never mentions a permit is a question worth asking.

What common AC repairs cost in DFW

Not every hot house needs a new system. These are the repairs we see most, with the range DFW homeowners are typically quoted and Lantern’s starting price for each.

Repair	Typical DFW quote	Lantern starts at
Capacitor or contactor	$220 to $380	$185
Drain pan and line clear	$150 to $350	$165
Refrigerant leak search and test	$250 to $600	$299

AC tune-up	$75 to $150	$79
Condenser coil cleaning	$100 to $250	$99

Typical DFW ranges come from Lantern’s own pricing sheet, compiled from quotes seen across the metro. Lantern prices are starting prices. The final number for your job is confirmed in writing before any work begins.

Repair or replace?

A quick gut check is the $5,000 rule: multiply the age of your system by the repair quote. Over $5,000, start comparing against a replacement. Under it, the repair usually makes sense.

A few things override the rule either way:

• Refrigerant. A leak on an older R-410A system can get expensive to keep refilling.
• Warranty. A repair covered by a parts warranty changes the math completely.
• The trend. A third repair in two summers says more than any single quote.

If you are on the fence, our repair or replace calculator walks through it with your own numbers.

How to read a replacement quote

Ask for these on separate lines. A good contractor will not mind.

1. Equipment model numbers for the outdoor unit, the indoor coil, and the furnace or air handler.
2. Labor, as its own number.
3. Ductwork, if any, with what is being repaired or replaced.
4. Permit and inspection.
5. Warranty, both parts and labor, and who honors it.
6. How the size was chosen. “Same as the old one” is not a load calculation.

If two quotes are far apart, it is almost always one of these lines. We dig into why HVAC quotes vary so much in this guide.

How Lantern prices a replacement

We charge what the equipment actually costs us, plus labor that starts at a posted price. The equipment line is the equipment, and the labor line is the labor, so you can compare us against any other quote line by line.

The audit is free. If a repair makes more sense than a replacement, we will say so. See our AC installation and AC repair pages, or call Lantern at (682) 337-0863.
