Generac, Kohler and Cummins standby generators installed across Phoenix, Scottsdale, Mesa and the rest of Maricopa County — sized for Arizona's air-conditioning load, wired to an automatic transfer switch, permitted, and coordinated with APS or SRP before energizing.
We are an electrical distributor that also self-performs installation, so the transfer switch, the load center and the feeder material come off our own shelf instead of a supplier's back-order list. That is usually where a generator job stalls.
Air-cooled and liquid-cooled standby generators that carry the entire house, including one to three air-conditioning compressors. Automatic start on utility loss, weekly self-test, transfer back when the grid returns.
A smaller set feeding a dedicated subpanel: one AC zone, refrigeration, well or pool pump, network gear, and the lighting and outlets you actually need at 2 AM. Lower cost, faster permit, smaller pad.
Service-entrance rated and load-side ATS installation, whole-home or split essential-load configuration, with load management modules so a smaller generator can still carry a large HVAC system.
Natural gas tie-in with the regulator and utility coordination when there is already gas service, or above-ground propane with tank placement, pad and line sizing when there is not. Fuel choice drives both cost and schedule.
A 4-ton compressor pulls 24–30A running and five to eight times that on start. We size from the AC nameplate locked-rotor amps, use sequential start delays, and quote a soft-start retrofit when it lets a smaller generator carry a bigger AC.
City or county electrical and gas permits, AHJ inspection, and the parallel-source notification APS and SRP require before a standby set can be energized. We hand the job over commissioned and load-tested, not just installed.
Phoenix metro pricing for a clean install on a standard residential lot with reasonable access. Difficult tank placement, long gas runs or a service upgrade push these higher — which is why the estimate happens on site, not on the phone.
| Install scope | Typical cost | Timeline incl. fuel |
|---|---|---|
| 14 kW — essential circuits subpanel | $7,800 – $11,500 | 3–4 weeks |
| 22 kW — whole-home, one AC | $11,500 – $16,800 | 3–5 weeks |
| 26 kW — whole-home, two ACs | $16,500 – $24,000 | 4–6 weeks |
| 38 kW — large home, three or more ACs | $24,500 – $38,000 | 6–10 weeks |
| Add: 500-gal above-ground propane tank | + $2,200 – $3,800 | + 1–2 weeks |
| Add: natural gas regulator + utility coordination | + $900 – $2,100 | + 1–3 weeks |
A 200A automatic transfer switch is included in the whole-home scopes above. Full sizing methodology, brand comparison and utility requirements are in our 2026 Phoenix generator guide.
Most generator delays are not the generator. They are the transfer switch, the load center, the feeder wire or the meter combo sitting on someone else's back-order. We stock that material for our own commercial work, so a residential standby job pulls from the same shelf.
Standby generators installed across the Phoenix metro since 2009, through the grid-stress summers that tripled demand.
Square D load centers, breakers, feeder wire and conduit come from our own distribution side instead of a supply-house queue.
Parallel-source notification and inspection handled before energizing, so the set is legal to run the day it starts.
Written scope and estimate in English or Spanish, with the sizing assumptions spelled out instead of buried.
Call (480) 910-0867 or email [email protected] and we schedule a site visit in the Phoenix metro, usually within the same week. The visit covers panel and service size, AC nameplate data, gas availability and generator placement, and you leave with a written scope and a price range.
Tech Energy America installs whole-home and standby generators across Maricopa County, coordinated with Arizona-licensed installation partners. We are also an electrical distributor, so the transfer switch, load center and feeder material come from our own inventory instead of a supply-house back-order.
In 2026 a 22 kW whole-home set carrying one air conditioner typically runs $11,500 to $16,800 installed, and a 26 kW set for two air conditioners runs $16,500 to $24,000. A 14 kW essential-circuits install starts around $7,800. Propane tanks and gas utility coordination are added on top.
Size from the air conditioning, not the square footage. A 4-ton compressor draws 24 to 30 amps running and five to eight times that on start, so a 22 kW set is at its limit with one 4-ton AC. Two ACs generally means 26 kW or more, unless a soft-start retrofit brings the inrush down enough to keep a smaller set.
Yes. The install needs an electrical permit and, for gas work, a gas permit from the city or county AHJ, plus parallel-source notification to APS or SRP before the set can be energized. We pull the permits, meet the inspector and handle the utility paperwork as part of the job.
Three to six weeks is typical from signed estimate to commissioned set, driven mostly by generator availability and fuel work. Propane tank placement adds one to two weeks; a natural gas regulator with utility coordination adds one to three. Large liquid-cooled sets can run six to ten weeks.
We install Generac Guardian and Protector series, Kohler and Cummins standby generators throughout Phoenix, Scottsdale, Mesa, Chandler, Gilbert, Tempe, Glendale, Peoria and the surrounding Maricopa County cities.
