Who provides AC repair and replacement in North Mountain?
The short answer: AZ Trusted Air LLC is a licensed Arizona contractor, ROC 317368, repairing and replacing air conditioning across North Mountain and the wider Phoenix metro. A person answers our phone 24 hours a day at (623) 252-6403, we dispatch overnight when a call genuinely warrants it, and typical non-emergency arrival is 12 to 24 hours. Diagnostics are $69.95 on weekdays, credited toward any repair we perform.
North Mountain covers about thirty years of Phoenix building, roughly the 1960s through the 1990s, and that single fact changes how an air conditioning conversation goes here. In a 2006 master-planned subdivision, the original equipment all fails within about three summers of itself. On a North Mountain street, the house on the corner may be on its fourth changeout, the one next door on its second, and the one behind it still running a 1990s R-22 split system that somebody keeps nursing. There is no replacement wave here — there is a replacement season every year, permanently. What follows is what we charge, what the City of Phoenix permit rule actually says, what the rebate picture really looks like for a home on APS power in 2026, and what to check before approving a four-figure repair. Strip our phone number off this page and it should still be the most useful thing you read today about cooling a North Mountain house.
- North Mountain's 1960s-to-1990s build span means no two houses on a street share an equipment age, so replacement here is perpetual rather than a single neighborhood wave.
- Diagnostics are $69.95 weekdays 8am-6pm and $99.95 outside those hours, credited toward any repair, at one flat rate with no trip charge.
- Installed replacement runs $5,000-$7,000 for three tons, $6,000-$8,000 for four and $7,000-$10,000 for five; heat pumps carry no premium.
- Rooftop package units on the area's low-slope roofs add $400 to $600 for crane service.
- APS ended residential AC and heat pump rebates on January 1, 2026, so most North Mountain homes have no equipment rebate; SRP addresses can still claim Cool Cash.
- SRP Cool Cash pays roughly $75, $150 or $225 per ton by compressor type on AHRI-listed SEER2 15.2+ equipment, filed within six months of install.
- The federal 25C tax credit is repealed for equipment placed in service in 2026 and should not appear on any quote.
- Phoenix exempts like-for-like outdoor swaps under five tons of identical weight; relocating the unit or modifying wiring requires a permit.
What does a service call cost in North Mountain, and how does scheduling work?
Our fee structure is short enough to publish in full. A diagnostic visit is $69.95 weekdays between 8am and 6pm and $99.95 outside those hours, credited toward any repair we carry out. A second opinion costs the same and is credited the same way, and the written report with the readings on it is yours whether you hire us or not. A quote review is free, needs no site visit, and you can send the paperwork however suits you.
Scheduling works the way it works everywhere we serve. A person answers the phone 24 hours a day, seven days a week — not voicemail, not a callback queue. We dispatch overnight when a call genuinely warrants it: no cooling at all with a 112-degree afternoon coming, or an infant or an elderly resident in the house. Typical non-emergency arrival is 12 to 24 hours. We do not publish a same-day or two-hour guarantee, because in a Phoenix July that is a promise the calendar decides rather than the marketing department.
Because the cooling season here runs April into October, the useful month to have a system looked at is March, not the first 110-degree week when every phone in the Valley is ringing. Our maintenance plan is $25 per month per unit. Labour warranty runs two years on new equipment and one year on repairs. Financing is available through a third-party lender, subject to credit; see pricing for financing terms.
What does AC replacement cost for typical North Mountain homes?
Mini-splits run $1,000 to $3,000 per indoor head. Where a North Mountain house lands inside its range has little to do with the equipment and a great deal to do with what four decades of previous work left behind. Duct replacement is $1,000 to $3,000 on its own, and it is the line item that most often separates two quotes on the same street.
The 150-to-170-degree attic is the reason. Flex duct installed in a 1970s or 1980s house has spent forty summers in an oven, and what we find when we open an attic hatch in August is tape that let go years ago and insulation compressed flat where somebody crawled over it. Unlike a 2015 home with tested, sealed ducts, an older system can be losing conditioned air into a space hotter than the outdoor air. Put a new condenser on that duct system and you have bought a quieter machine and the same power bill.
Sizing is the other half. With a summer design temperature near 115 degrees, an ACCA Manual J load calculation is the only defensible basis for tonnage here, and swamp cooler conversions and added rooms mean plenty of North Mountain houses no longer match their original design load. On permits, the City of Phoenix exempt-work list covers repair or replacement in kind of outdoor refrigeration units not over five tons at one- and two-family dwellings, with the replacement identical in weight to what it replaces. Move the unit, change the footprint or modify the wiring and the city's counter vetting questions push the job back into permit territory. We pull one when the work requires it.
Installed system price by tonnage — and where SEER2 15.2 falls
AZ Trusted Air published ranges, same in North Mountain as metro-wide. The split marks SEER2 15.2, the efficiency SRP's Cool Cash requires.
On SRP power the upper portion earns Cool Cash at $75 to $225 per ton. On APS power, where most of North Mountain sits, residential equipment rebates ended January 1, 2026, so the efficiency step has to justify itself on running cost alone.
| Item | Range |
|---|---|
| 3-ton system | $5,000 – $7,000 |
| 4-ton system | $6,000 – $8,000 |
| 5-ton system | $7,000 – $10,000 |
What should North Mountain homeowners check before approving a major AC repair?
Start with the number against the part. A capacitor is $50 to $200, a contactor $100 to $200, a condenser fan motor $600 to $1,200, a blower motor $750 to $1,800, a compressor $800 to $4,000. If a quote sits well outside those ranges, ask what the measurement was — microfarads on the capacitor, amp draw on the motor, pressures on the compressor. A technician who took the reading can tell you what it said.
Refrigerant decides the rest, and in North Mountain that question is live in a way it is not in a 2010 subdivision. R-22 production and import ended in 2020 under the EPA's phase-out, so anything still charged with it depends on reclaimed supply. Homeowners with a 1990s system consistently find the leak search, the charge and the part all cost real money to keep alive a machine that cannot be economically recharged next time. That is a different calculation from the same repair on an R-410A unit, and different again now that new equipment ships with R-454B — see R-22 replacement and repair or replace.
Two line items get blurred everywhere. Coil cleaning is $150; coil replacement is $2,200 to $2,600. A quote saying only "coil" should be clarified before anyone signs. And check the manufacturer parts warranty before approving a compressor: a covered compressor where you pay labour only sits near the bottom of that $800 to $4,000 spread.
Phoenix exempts repair or replacement in kind of outdoor refrigeration units not over 5 tons at one- and two-family dwellings, provided the replacement is identical in weight. The counter guideline then asks a short list of questions — different location, different footprint, wiring or duct modification — and any yes means a permit is required. That is the whole test, and it is public.
Which rebates can North Mountain residents claim on a replacement, and who handles the paperwork?
The 2026 answer is blunter than most homeowners expect. APS discontinued its residential AC and heat pump rebates effective January 1, 2026, following the Arizona Corporation Commission decision in late 2025 that cut its efficiency-program budget. If a bid you are holding shows an APS equipment rebate line, that line is stale. What remains on the APS side is Cool Rewards, a smart-thermostat demand-response credit rather than an equipment rebate; confirm current terms with APS directly. We are not an APS Qualified Technology Installer and will not promise you an APS rebate.
SRP's Cool Cash is the program still paying on replacements, and some Phoenix addresses sit on SRP power where neighbouring streets do not — the boundary follows a decades-old service line rather than city limits, and your bill names your provider. SRP pays by the ton and by compressor type: about $75 per ton single-stage, $150 multi-stage and $225 variable-capacity, on AHRI-listed equipment at SEER2 15.2 or better, application due within six months of installation and a Manual J required on single-stage systems. Verify current amounts with SRP before relying on them.
Two smaller SRP items are worth knowing: a duct test and repair rebate covering 75 percent of qualified testing and sealing costs up to $400 for a single-family detached home, and smart thermostat credits of $50 per device. The federal 25C credit is not part of this picture — it is repealed for equipment placed in service in 2026, and any quote treating it as live is wrong. Our rebate concierge completes and files SRP and ED3 paperwork on qualifying jobs.
