HVAC replacement cost in Dallas: what 1,785 city permits show
The median declared value for residential HVAC replacement in Dallas was $12,855. Half of all jobs fell between $8,000 and $17,085.
When a contractor replaces a heating and cooling system at a Dallas home, the permit application states what the job is worth. We read every residential mechanical permit that carried a declared value and kept the ones for system replacements.
The middle of the pack is wide: half of all replacements were declared between $8,000 and $17,085. Most of that spread is explained by two things the permit descriptions name, how much of the system was replaced and how big it is.
What moves the number
| Group | Permits | Median | Middle half |
|---|---|---|---|
| Full system (condenser plus furnace or coil) | 531 | $14,066 | $8,700 to $18,132 |
| Heat pump named in the description | 77 | $12,100 | $7,000 to $18,245 |
| Condenser only | 44 | $6,250 | $4,255 to $8,339 |
| Furnace only | 141 | $4,885 | $2,500 to $7,200 |
Groups are built from the words in each permit description. A permit that names only a condenser, or only a furnace, is counted in that row.
| Group | Permits | Median | Middle half |
|---|---|---|---|
| 2 ton | 77 | $10,149 | $6,400 to $12,980 |
| 2.5 ton | 78 | $11,809 | $6,022 to $14,836 |
| 3 ton | 277 | $12,909 | $7,500 to $16,382 |
| 3.5 ton | 76 | $13,287 | $9,393 to $16,996 |
| 4 ton | 219 | $15,000 | $9,900 to $18,299 |
| 5 ton | 200 | $15,418 | $11,043 to $20,291 |
Permits that name exactly one system and one size.
What stands out
- Size moves the median from $10,149 for a 2-ton system to $15,418 for a 5-ton system.
- Replacing only the furnace had a median of $4,885. Replacing only the outdoor condenser had a median of $6,250.
- The median barely moved over the year: between $12,000 and $13,580 in every quarter.
When the work happens
What this number is, and is not
- It is the job value a contractor declared on a City of Dallas permit application. It is not an invoice, and the city does not audit it.
- It covers work done under a permit inside the city limits. Jobs done without a permit, and jobs in the suburbs, are not in the file.
- It describes the spread of past jobs. It is not a quote for your home.
- How we picked these permits: Mechanical permits whose description says a heating or cooling system, condenser, furnace or heat pump was replaced, changed out or installed. Duct-only work is left out.
Before you sign
- Put your quote next to the middle-half range above. If it sits outside, ask what is different about your job.
- Ask whether the price includes pulling the city permit, and ask for the permit number.
- Get the scope in writing: the brand, model numbers, system size in tons, efficiency rating, and whether ductwork, the thermostat and haul-away are included.
- Texas licenses air conditioning and refrigeration contractors through the Texas Department of Licensing and Regulation (TDLR). Search TDLR licenses.
