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

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 Tucson, AZ the all-in is $4,944 low, $7,382 typical, and $21,229 high. Those all-in figures add the model's rounded permit for the official trade bands. The official fees are $168.54, $218.54, and $218.54. The model rounds each to the nearest dollar before adding it, so the all-in uses $169 on the low, $219 on the typical, and $219 on the high. The typical listed fee is the 2-item trade path (a furnace plus a 3-ton air conditioner), not a per-ton permit. The permit is a flat trade fee, so it is not rescaled when the system count changes. The other table rows are 2 systems at $14,544 typical and 3 systems at $21,707 typical.

How much does HVAC replacement cost per system in Tucson?

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 $218.54. The cost-by-size table shows that fee on each of those rows, because this permit is a flat trade fee and is not rescaled when the system count changes. At 1 system in Tucson, AZ the all-in typical is $7,382, which is $7,382 per system after rounding to the nearest dollar. At 2 systems the all-in typical is $14,544, or $7,272 per system. At 3 systems the all-in typical is $21,707, or $7,236 per system. Those per-system figures are that division of the row. They are not a separate published rate.

Published national HVAC replacement prices average $7,500, commonly run $5,000 to $12,500, and reach up to $22,000 with new ductwork. $15,000 is above that $12,500 common high and below that $22,000 new-duct figure. Wage-indexed, the high at 1 system in Tucson, AZ is $21,229. $15,000 is below that adjusted for local wages high and above the typical.

The official permit on this row is $218.54 typical and high, and $168.54 low. Those fees come from 4-02.9 item count, not from project value. The official typical project value is $7,500, and no assumed valuation is listed on this row. $15,000 is not a valuation input, so this row does not list a permit fee for a $15,000 project value. The all-in figures add the model's rounded typical permit of $219. They do not look up a Table 4-02.4 fee at $15,000.

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

On the official path, yes. City of Tucson Planning and Development Services Department (PDSD) is listed as requiring a permit for a typical HVAC replacement in Tucson, AZ, and the official typical fee is $218.54. The cited source is the City of Tucson PDSD FY27 Planning and Permitting Fee Schedule, 4-02.9 Trade Permits, retrieved 2026-09-01. HVAC change-out is listed trade F (Air Conditioner/Heater Repair/Replace, max 2), not Table 4-02.4 valuation. A 1-item change-out is the first item $150 plus the digital filing minimum $18.54, so $150 + $18.54 = $168.54. The typical furnace plus 3-ton path is two items: $150 + $50 + $18.54 = $218.54. High equals that typical ($218.54) because the listed maximum of 2 items is already the typical band. Digital filing is 1% of the trade-permit fee, and on both bands that 1% is below the $18.54 minimum, so the minimum is the digital filing line. This row does not record a $0 exemption for a like-for-like change-out. The official typical stays $218.54.

What does a 1-unit versus a 2-unit HVAC change-out permit cost in Tucson?

On section 4-02.9, a unit is a listed trade item, and trade F (Air Conditioner/Heater Repair/Replace) allows at most 2. A 1-unit change-out is the first item at $150 plus the digital filing minimum of $18.54, which is $168.54. A 2-unit change-out adds one additional item at $50. The trade lines are $150 + $50 = $200, and digital filing stays the same $18.54 minimum because 1% of either subtotal is below that minimum, so $200 + $18.54 = $218.54. The extra $50 is the only difference between the official low and the official typical. High equals the typical $218.54 because the listed maximum of 2 items is already the typical band. This row does not price a third item. The typical 2-item path on this page is a furnace plus a 3-ton air conditioner. Tonnage does not change the fee. The cost model is separate: it prices one complete system as the typical job and adds the rounded typical permit of $219 on that row. It does not switch the all-in to the 1-item fee of $168.54 when the calculator is set to 1 system.
