How much does a 3-ton HVAC replacement cost in Dallas?

The documented typical job is a 3-ton (36,000 BTU) like-for-like split system. This cost model prices that job as one system. It does not price tons as a separate rate. The cost-by-size rows are 1 system, 2 systems, and 3 systems. The calculator scales the installed job by the system count divided by 1, and 1 is inside the allowed range of 1 to 4, so these figures are that same scale. At 1 system in Dallas, TX the all-in is $5,105 low, $7,500 typical, and $21,421 high. Those all-in figures add the model's rounded permit for the valuation bands on this row. The official fees are $315, $315, and $345.39. The model rounds each to the nearest dollar before adding it, so the all-in uses $315 on the low, $315 on the typical, and $345 on the high.

Do I need a permit to replace an air conditioner or furnace in Dallas?

On the official path, yes. Planning and Development – Building Inspection (Development Services) is listed as requiring a permit for a typical HVAC replacement in Dallas, TX, and the official typical fee is $315.

At the official $7,500 valuation the Table B-I minimum of $175 binds, so $175 + $125 + $15 = $315. Low $5,000 is the same minimum path, which is $315. High $16,000 is value × 0.009652 × 1.33 = $205.39, then $205.39 + $125 + $15 = $345.39. Chapter 52 §301.2.3(8) exempts like-for-like permanent electric HVAC with no rough-in change. A typical gas furnace plus air conditioner is not that exemption, and this row does not add a $0 line for it. The official typical stays $315.

What does an HVAC replacement permit cost at $5,000, $7,500, and $16,000 in Dallas?

Listed assumed valuations for HVAC replacement in Dallas, TX are $5,000 low, $7,500 typical, and $16,000 high. The official typical project value is $7,500. Table B-I is max($175, value × 0.009652 × 1.33) plus $125 plus $15. Low and typical stay on the $175 minimum because the valuation line is below that floor on both bands; a separate valuation-line dollar at $5,000 or $7,500 is not listed. So each of those bands is $175 + $125 + $15 = $315. High $16,000 is value × 0.009652 × 1.33 = $205.39. The $175 minimum is not binding because $205.39 is higher, so $205.39 + $125 + $15 = $345.39. The official extras are the $175 Table B-I minimum permit, the $125 additional inspection per trade, and the $15 technology fee, and all three are included in the typical total.
