Donley A/C & Plumbing

Donley A/C & Plumbing specializes in installing energy-efficient air conditioning systems tailored to Arizona's climate. Our technicians assess your home's cooling needs and recommend high-quality units that reduce energy consumption while maximizing comfort. We handle all system types, including ductless mini-splits for homes without existing ductwork.

We provide urgent plumbing repairs for leaks, clogs, and water damage prevention. Our team uses professional-grade tools to locate hidden leaks and repair damaged pipes, minimizing structural risks. Services include fixture installation, repiping, and drain clearing for residential and commercial properties.

Donley came out to repair an A/C system and they diagnosed the problem immediately. They proceeded to clean out a clogged drain pipe that was in the garage (very easy access) and it took only about 10 minutes to clear out the clog with compressed air and then pour water through it (only one plastic zip tie was needed during the repair, no other parts). For the few minutes they were here including diagnosis, unclogging the pipe, and filling out the paperwork, they charged me over $200, not including the $89 service fee.

So for being here less than 20 minutes, their bill was over $300. Be sure to get an estimate from them prior to any work, as in my opinion, they charge a grossly inordinate amount relative to the amount of time they spend on the repair. Not including the service fee, their charges were equivalent to a labor fee of over $600 per hour.

We heard about Donley AC on AZ Family channel 3 and called them because our AC was not working. A tech came out and inspected the unit, and informed us of the repair choices, we chose to have a new unit installed. Their salesmen came to our house and provided choices of units. We went with a Goodman unit, and very satisfied with the price and quality. My sister in law told me that their AC unit was acting up, they did call a different AC company who wanted to charge them quite bit.

I told my sister in law about Donley AC, my sister Rachel called Donley AC and explained their AC issues and the fact my sister has been diagnosed with cancer and after her treatments her body gets very hot. They sent a tech named Jason, he went to her house, said they did not have a leak and did not need to get a new unit like as they have been told from the other place. Jason was there for over an hour and did some maintenance work and did not charge my sister.

This just goes to show that Donley AC is about honesty and professionalism and caring. Thank you very much Jason and the Donley AC family for taking care of my sister. I highly recommend this company to eveyone.

I have used Donley for years. I love their maintenance package! It keeps our system running reliably. Super easy scheduling. Juan (my favorite technician) is always on time, super pleasant, does an excellent job of keeping us cool. Thanks for all the years of great service

We had a sizable slab leak occur and needed emergency service to prevent more water loss. Donley's service was amazing! On time, responsive, and so very professional! They brought in a leak specialist and pinpointed the problem in very short order. We couldn't be happier with the service and professionalism!

We bought a combo heat pump unit 3 years ago ( over $5000). Unit would not turn on to heat this year. Called Mike Carroll, salesman who sold us unit. He told me there would be NO CHARGE to come out and check unit. Made appt and two days before date they texted to say THEY changed appt to the next day. Called them and made arrangements to come on the day they were suppose to. Jason showed up on time and determined problem was the thermostat.

He said it would be $79.00 for diagnostic service and ARE YOU READY FOR THIS $330.00 to replace the thermostat that costs less than $30.00 at home depot. Told him to contact Mike about service charge and NO THANK YOU on something that should cost less the $100 total to replace. Bought new thermostat for $28.00 and replaced same in less that 10 mins. Service Tech's make commission on UP SELLING customers.

Well don't worry Donley and Mike I'm due to change both my 3 and 3.5 Trane units that are over 20 years old and I won't be checking with YOUR company. You just lost over $10,000 thanks to JASON.

We had another fabulous experience today with Donley! Our jetted tub water would not shut off so we had to turn off the water to the house which is inconvenient to say the least. Travis arrived on-time, was able to secure parts and fix our tub and repair a couple other fixtures (shower/sink). He was knowledgeable, professional and a pleasure to have in our home. Everything is now back in working order and we cannot be happier. I highly recommend their plumbing services!

Our home warranty company (Old Republic Home Protection - the worst) covers some plumbing issues (or are supposed to). But their contractors either aren't very skilled and/or they try to drive up costs so the warranty co will pay more. I've had a few plumbing issues that were fairly simple yet 4-5 different plumbing companies contracted by the warranty company were unable to fix. After 4 mos of a leaky faucet which even I knew needed a replacement cartridge it is finally fixed!

At least 4 other plumbers couldn't figure out this latest issue (saying the cartridges were stuck and they couldnt replace) instead said a demolition of my bathroom was the only next step - crazy. I called Donley on a Monday, they came and fixed the faucet on Wednesday. Professional, reliable, honest, trustworthy, straightforward. So refreshing after the horrible experiences we have had. Thank you!
