Listed Table A totals are $243 at $5,000, $558 at $7,500, and $726 at $16,000. At the typical valuation the official plan review is $279, and because that review is 100% of the permit fee the building portion is the same $279. Plan review applies when valuation is over $5,000, so the $5,000 low total has no separate plan-review dollar. Full arithmetic is in the calculation note on this page.

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

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 Phoenix, AZ the all-in is $5,148 low, $7,916 typical, and $22,308 high. Those all-in figures add the model's rounded permit for the valuation bands on this row. The official fees are $243, $558, and $726. The model rounds each to the nearest dollar before adding it, so the all-in uses $243 on the low, $558 on the typical, and $726 on the high. The permit is based on project value, so it is not rescaled when the system count changes, and it is not a new Table A fee for 1 system. The other table rows are 2 systems at $15,273 typical and 3 systems at $22,631 typical. Listed assumed valuations behind those permit lines are $5,000, $7,500, and $16,000.

How much does HVAC replacement cost per system in Phoenix?

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 $558. The cost-by-size table shows that fee on each of those rows, because this permit is based on project value and is not rescaled when the system count changes. At 1 system in Phoenix, AZ the all-in typical is $7,916, which is $7,916 per system after rounding to the nearest dollar. At 2 systems the all-in typical is $15,273, or $7,637 per system. At 3 systems the all-in typical is $22,631, or $7,544 per system. Those per-system figures are that division of the row. They are not a separate published rate.

Is $15,000 too much for HVAC replacement in Phoenix?

At the model's typical one-system job (a 3-ton (36,000 BTU) like-for-like split system) in Phoenix, AZ, the all-in is $5,148 low, $7,916 typical, and $22,308 high. $15,000 is above that typical of $7,916. Published national HVAC replacement prices run about $5,000 to $12,500 for a common job, with an average of $7,500 and up to $22,000 with new ductwork. $15,000 is inside that published high band and above the average. Wage-indexed, that high is $22,308 at one system in Phoenix, AZ. $15,000 is below that adjusted for local wages high and above the typical. On the typical path the same scale first reaches $15,000 at 2 systems ($15,273 typical), which is above the one-system job this page uses as typical. The official permit on this row is $558 at a $7,500 valuation, $243 at $5,000, and $726 at $16,000. $15,000 is below that listed high valuation of $16,000, but this row does not list a separate permit fee for a $15,000 project value. The all-in figures add the model's rounded typical permit of $558. They do not look up a new Table A fee at $15,000.

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

On the official path, yes. Planning and Development Department (PDD) is listed as requiring a permit for a typical HVAC replacement in Phoenix, AZ, and the official typical fee is $558. Ordinance G-7465 Table A sets the building permit from the project valuation. Residential ≤$50k: plan review is 100% of the permit fee, minimum $195, when valuation > $5,000, and that review is included in the official totals. At the official $7,500 valuation the building permit portion is $279 and plan review is $279, so $279 + $279 = $558. Low $5,000 is a building permit portion of $243 with no separate plan-review dollar, which is $243. High $16,000 is a building permit portion of $363 plus plan review of $363, which is $726. The $195 minimum would apply only when 100% of the building permit fee is under $195. From $5,001 through $6,000, Table A is $255, which is already above $195, so that floor does not raise the official totals. Same Table A as other building work; no separate mechanical permit in the PDD schedule for a standard replacement. The official typical stays $558.

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

Listed assumed valuations for HVAC replacement in Phoenix, AZ are $5,000 low, $7,500 typical, and $16,000 high. The official typical project value is $7,500. The typical and the high are over $5,000 and at or under $50,000, so plan review is 100% of the building permit fee on those bands. The low is exactly $5,000, so plan review does not add a separate listed dollar on that band. The $1,001 to $10,000 line is $195 on the first $1,000 plus $12 for each additional $1,000, or fraction of $1,000. Low uses that line: building portion $243, no separate plan-review dollar, total $243. Typical uses the same line: building portion $279, plan review $279, total $558. The $10,001 to $50,000 line is $303 on the first $10,000 plus $10 for each additional $1,000, or fraction of $1,000. High $16,000 is on that line: the amount over $10,000 is $6,000, which is 6 times $10 = $60, so the building portion is $303 + $60 = $363, plan review is $363, and the total is $726. The official plan review extra is the typical $279, and it is included in the totals. From $5,001 through $6,000, Table A is $255, already above the $195 plan-review floor.
