HVAC reviews across the US

I have had Dave do a few things for me including a central air installation and two A/C repairs at other properties. Not only did he have the most reasonable bid on the main job, the other jobs were reasonably priced as well. Price aside, the prompt, efficient and courteous service was the best part. I wish every contractor would take lessons from this guy. Thanks Miller Mechanical!!

I called Dave without any air conditioning in a 98° heat wave. He could've told me what everyone else had been saying when I called around that it was 2 weeks out for service. Dave came out the same day and fit me in. He fixed the issue quickly. He was professional and kind. I will be using his services from now on. Would highly recommend him to anyone. My air conditioning is cooling great now!

We were out of town when our daughter informed us that our water heater was leaking water. He was able to quickly fix the problem quick.

We had two separate issues with hot water heater and backed up plumbing. Dave diagnosed/problem shot both issues and fixed with such efficiency! Happy to have had him for our repairs!

They laid off staff so no one can get serviced.

Called and left messages daily for 2 weeks, no return call

Very professional exceptional service. I would recommend this company to everyone!

Doesn’t return calls. Bad business!

Great service has been on time for every appointment. Bought a new heater and HVAC they were quick and very nice.

Great work! I'm extremely happy with Jones Plumbing. My sink is fixed and no more leaks. I highly recommend these guys.

My central air stopped working last night and of course it was 100 degrees outside. He was here the next day and it was up and running again. Also, fixed the backed up plumbing issue we unexpectedly had. On a hot day like this I couldn’t have asked for better service. Thank you for your excellent service. Highly recommended!

Awesome service! They were called and got here the next day! Fixed our central air and a plumbing issue. And we are grateful to have that running properly again! They were quick and very efficient! I definitely recommend them!

Warren came to perform my HVAC routine maintenance. He was punctual, polite, engaging, knowledgeable, and very communicative. He collaborated on a creative idea for my drain and offered parts support. He also recommended a plumbing fix and obtained cost estimates in real time. He went above and beyond. Haley continues to deliver high quality service. Thanks to all who support this for customers.

Marc McDermott & Rob Sutch have really went to bat for us & given us Outstanding customer service through out our entire AC install. Great communication & easy to work with.

Zeke, set us up right from the very beginning, so thorough & wonderful to work with.

Eric installed a new electrical panel for us & was equally wonderful & went the extra mile when we needed it most.

Thank you so much!

We had two days in a row of needing assistance. Haley was professional, and knowledgeable! Aaron and Bryan both assisted us and knew how to help and provide friendly and detailed assistance!! Customer service also was top notch it scheduling a follow up quickly! Will definitely use them again and recommend!!!

I'd like to say thank-you to KJ from Haley's Mechanical,who installed a new hot water heater for me, on a Sunday! KJ was helpful, knowledgeable, and kind. I am happy with the work, with KJ's offer to work around my schedule, and with the promptness in getting hot water back in my life. I would call Haley's again if needed.
Thanks for a job done well and done quickly. Appreciation.

Matt solved the issue in just a few minutes. He was professional, knowledgeable, and easy to work with. Haley Mechanical provided great service at a fair price with no pressure or upselling. I highly recommend them and will use them again in the future.

Mark G txted and called to let me know he was 20 minutes out. He arrived during the first hour of the window of time in which I was told to expect him. From the start he was friendly, gracious, patient and kind with my dogs, and very thorough.

He spent about 2 hours going over the AC unit, both the interior and exterior portions. He also did some peripheral inspection of the furnace and water heater. He did both a visual inspection of all of the parts, as well as a lot of diagnostic testing of the electrical components and analysis of air in the intake and outflow pipes. I know this because he was kind enough to let me tag along and watch what he was up to.

Along the way he explained everything, gave me maintenance tips, and offered advice about how long certain things should last and what I might consider doing, and what might not be worth the expense given the age of the system.

I appreciated him explaining things to me because this is the first home with central air that I have owned, and in the months since we bought the house I had realized how ignorant of the system’s working I am. Also, because we bought the home in the winter, it wasn’t possible for the home inspector to properly evaluate the AC, because it was too cold to switch it on.

For what struck me as a very reasonable fee of $150, Mark not only evaluated and cleaned the AC system, and to some extent the furnace, he also educated me on how this portion of my house operates. Within a couple of hours after our meeting he sent an email with attached docs letting me know the pricing of various replacement options if I decide to go that route. I have a lot more peace of mind now, and for that I am grateful. Many thanks to Mark, and to Haley for making the scheduling easy!

I wanted to add a generator cut-over switch for my natural-gas-fueled heating system so that we could still get heat during power outages by powering the furnace system from a battery backup or a generator. On Dec. 17, 2025 Haley Mechanical sent out a technician, Dustin, to look at what I wanted to do. He understood immediately what I wanted, and he was in and out in under 10 minutes. A few hours later I got the quote for the work. It was a little higher than I had hoped, but I decided to accept the quote, because I was confident that the work would be done correctly.

Because of the holidays, it took a little while to get the work scheduled, but finally on Jan. 15, 2026, another technician named Kaydin came out to install the switch. Again, he knew exactly what to do, and installed the new hardware without difficulty. The whole operation took about two hours.

Kaydin also helped me test the cut-over switch, which we did by turning off the furnace power, connecting an extension cord between my Jackery battery backup system and the cut-over switch. When we flipped the switch from "LINE" to "GEN", the furnace immediately turned on, fired up the boiler, and within a few minutes the system was successfully pumping hot water to all of the radiators in the house. The Jackery indicated that the power draw was between 60 and 70 watts, so I figure that the Jackery could power the furnace for roughly 14 hours, even without re-charging it with the solar panels. So, I was completely satisfied that this cut-over switch gave me the heat security that I wanted. I have attached a picture of the switch and how it is connected to my furnace's power.

I especially appreciated how Kaydin handled the bitterly cold weather that we had that day. I had asked him to bring his equipment in and out through the garage, but to also make sure to close the garage door whenever he was done moving things to prevent heat loss through an open garage. I heard him open and then close the door multiple times, and so our home stayed nice and warm despite the frigid weather.

Colin did exceptional work and we are very pleased with the pendent lighting installation in the kitchen. He was thorough and did a good cleanup job after the work. Colin also provided a quick quote for additional work we needed done which allowed us to go ahead and order parts.
We got the extra light we ordered in and immediately called Haley to schedule Colin for the install. That was done promptly Colin came and within 45 minutes we had the new hall light installed. Excellent and timely work . Thank you!

Called for service. Left message on voicemail. No one ever bothered to return my call.
