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

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 Fort Worth, TX the all-in is $4,846 low, $7,251 typical, and $21,149 high. Those all-in figures add the model's rounded permit for the equipment bands on this row. The official fees are $56.05, $66.39, and $72.51. The model rounds each to the nearest dollar before adding it, so the all-in uses $56 on the low, $66 on the typical, and $73 on the high. The permit is equipment-tiered on Table 1-H plus Table 1-B, so it is not rescaled when the system count changes, and it is not a new Table 1-H fee for 1 system. The other table rows are 2 systems at $14,436 typical and 3 systems at $21,621 typical. Listed assumed valuations on this row are $5,000, $7,500, and $16,000, and they do not change those listed fees.

How much does HVAC replacement cost per system in Fort Worth?

Cost per system on this page is the all-in typical divided by the system count on that row. One system is a complete heating-and-cooling change-out, not a single trade item and not a ton of capacity. The cost-by-size rows are 1 system, 2 systems, and 3 systems. The official typical permit fee is $66.39. The cost-by-size table shows that fee on each of those rows, because this permit is equipment-tiered and is not rescaled when the system count changes. At 1 system in Fort Worth, TX the all-in typical is $7,251, which is $7,251 per system after rounding to the nearest dollar. At 2 systems the all-in typical is $14,436, or $7,218 per system. At 3 systems the all-in typical is $21,621, or $7,207 per system. Those per-system figures are that division of the row. They are not a separate published rate.

The typical walk is furnace ≤100,000 BTU $6.10 plus condensing unit over 2 including 3 tons $10.34 plus Table 1-B $49.95. $6.10 + $10.34 + $49.95 = $66.39. Table 1A-1 1-trade remodel is the building-remodel path if HVAC is bundled into a remodel permit, and Electrical Table 1-J is extra if a new circuit is pulled.

Why are the low, typical, and high HVAC permit fees $56.05, $66.39, and $72.51 in Fort Worth?

The low, typical, and high are equipment bands on Table 1-H plus Table 1-B, not a valuation table. Listed assumed valuations are $5,000 low, $7,500 typical, and $16,000 high. The official typical project value is $7,500. Those valuations are unused because the fee is equipment-tiered, not valuation-driven, and they do not change the official $56.05, $66.39, and $72.51 fees. $33.08 + $16.87 = $49.95. That application and technology total is included at the low, the typical, and the high, and it is not added again. Low is a 2-ton AC-only path: condensing unit ≤2 ton $6.10 plus Table 1-B $49.95. $6.10 + $49.95 = $56.05. Typical is furnace ≤100,000 BTU $6.10 plus condensing unit over 2 including 3 tons $10.34 plus Table 1-B $49.95. $6.10 + $10.34 + $49.95 = $66.39. High is furnace ≤100,000 BTU $6.10 plus condensing unit over 3 including 5 tons $16.46 plus Table 1-B $49.95. $6.10 + $16.46 + $49.95 = $72.51. The $72.51 high is not added on top of the $66.39 typical. The model rounds those listed fees to $56, $66, and $73 before adding them to the all-in estimate.
