• I recently had another great experience with Wolff Mechanical Inc. This time my technician was Brandon, and I couldn’t be happier with the service I received. Brandon was punctual, professional, and extremely knowledgeable. He quickly diagnosed the issue, explained everything and made sure the repair was done right. What stood out most was how thorough he was—he answered my questions, kept me informed throughout the process, and made sure everything was working properly before he left. With Arizona summers, having reliable air conditioning is essential, and thanks to Brandon my AC is running perfectly again. The entire experience was smooth from start to finish, and I really appreciated the level of service I received. I wouldn’t hesitate to recommend Brandon or Wolff Mechanical Inc. to anyone needing AC service. Thanks again for the outstanding service!

• Always get excellent service from Wolff. Brandon came yesterday and did the annual mainland also pointed out a plumbing problem which could have caused major issues. Thank you Brandon!

• Used this company a few years ago for an ac tune up. Ended up with my upstairs flooded because they didn’t check the drip pan. Do yourself a favor and stay away.

• This driver for your company is extremely aggressive and almost caused two accidents. They were speeding and trying to pass between and tail cars while going over the speed limit. The vehicle number is 128.

• ⭐⭐⭐⭐⭐ 5-Star Review for Wolff Mechanical OMG!!! Wolff Mechanical is hands down the most honest, knowledgeable, and professional AC company I’ve ever dealt with. Before calling them, I had two other companies come out, and both told me I needed a new compressor and quoted me nearly $4,000. I believed them—until I noticed a Wolff Mechanical sticker on my AC unit and decided to give them a call. Their technician arrived on time, diagnosed the issue within minutes, and told me my compressor was completely fine. He even advised me to call the factory to check if my unit was still under warranty. While I was on the phone with the manufacturer (and found out my warranty had expired), the technician had already fixed the problem—a simple wire contact. No upselling, no scare tactics, just honest work. These guys are incredibly trustworthy, skilled, and professional. If anyone in Arizona needs AC service, there’s truly no one better than Wolff Mechanical. Thank you so much for your outstanding service!

• This review is for their Technician Derek, who came out to replace a part on one of our Daiken AC units yesterday. He got it replaced very quickly but stayed and also answered many questions I had and also helped troubleshoot a different issue I was having with my AC. He was fantastic.

  Clinton J.★★★★★

• My repair required a backordered part and throughout the process, the full staff - from the scheduler, to the technicians, to management - were helpful, knowledgeable and friendly. Their teamwork and actions to expedite the repair was greatly appreciated. A very positive experience.

  Joyce R.★★★★★

• Wolff Mechanical saved the day! After getting the runaround from Honeywell reps—who repeatedly recommended the wrong thermostat despite me clearly stating I needed desktop (Total Connect) and Android compatibility—Wolff Mechanical stepped in with the right answers. Their team quickly identified the Vision Pro 8000 as the proper solution when no one else did. Special thanks to Brandon, the HVAC tech, who called me back and took time to discuss the issue with me during a busy workday. His professionalism and willingness to listen and help made all the difference. I truly appreciated the clarity, product knowledge, and customer care Wolff provided after such a frustrating search. Highly recommended!

• The recent HVAC service call with Wolf Mechanical was fantastic. We returned from vacation to a very hot house and an AC unit that was not working. As it was Friday and 110+ degrees, I was very concerned about getting it fixed before the weekend. A technician was scheduled for the same day. Diego arrived promptly and was very friendly and professional. The problem was quickly diagnosed as a bad capacitor which was still covered by the warranty. Diego had the necessary parts and repaired the unit in under an hour. He took the time to explain the issue and repair process and took time to answer all of my questions. We have used Wolf Mechanical for almost 20 years and they always do a great job and have great technicians. Thank you, Wolf Mechanical and Diego, for your great service.

  Renee K.★★★★★

• I had an outstanding experience with Wolff Mechanical Inc, thanks to their amazing technician, Jim. He was professional, knowledgeable, and truly went above and beyond. Jim arrived on time, quickly diagnosed the issue with my AC, and took the time to clearly explain what was going on and how he would fix it. His expertise and attention to detail were obvious, and I appreciated how thorough and respectful he was throughout the entire process. It's not often you come across service like this — I highly recommend Wolff Mechanical Inc, and if you get Jim as your technician, you’re in great hands!

  Dorothy F.★★★★★

• Very pleased with the immediate attention, expertise, and professionalism of Wolff Mechanical! Brandon provided solutions for our inefficient HVAC and duct work in moments, where another service could not. Thank you Brandon, Tyler, Shelly and team, you guys are so hot, you're cool!!

• Here is is 8 year later after this initial review and nothing has changed. Derrick came out for a emergency service for a write up I had on a home inspection and was adamant on not selling me something that wasn't needed or required. You don't see this type of service much anymore where customer service is priority instead of selling you something you don't need. I have used Wolff Mechanical for over 20 years and wouldn't use anyone else. They installed the original system that lasted over 23 years and never tried to sell me something I didn't need. Most of my neighbors are on their second or third A/C units. That's why I only went to Wolff Mechanical when I was ready to install a new system. Tim came out gave me different options, no high pressure sales tactics and I can't be more pleased with the results. The install crew were very professional and courteous. Working for an industrial supply company I've heard horror stories how some companies treat their customers by charging them for something they didn't need.

• We use have been using Wolf for a few years now. They always provide exceptional service. Derek serviced several of our properties for our semiannual servicing recently and helped with a small thermostat issue. He is very kind, patient and knowledgeable.

  Dana M.★★★★★

• Wolff Mechanical is the best HVAC company I have ever dealt with. I had an issue with a residential unit that I bought about 5 years ago, and Tyler and Brandon went ABOVE and BEYOND on customer service to resolve my issue. All of the technicians are very helpful and prompt to arrive during the scheduled window. Highly recommended!!!

  Greg W.★★★★★

• Wolff Mechanical is the best....every time! Yesterday my AC unit wasn't cooling properly. I called the Wolff office, and they scheduled a technician who arrived within the time frame I was given. Josh was professional, courteous, experienced, and had my AC unit up and running right away. He knew exactly what the issue was, had the parts on his truck, and my AC unit was back working perfectly. Thank you!!!

  June T.★★★★★

• Friendly service techs, but had to wait over 2 weeks for a new AC unit to be installed. I guess they get a lot of business. I would not recommend agreeing to wait longer than a couple days for installation.

• I purchased my first AC from Wolff over 16 years ago when I bought this house in Chandler, and have had their priority customer service agreement for the past 16 years. Over that time, they've consistently shown up on time, done great work and been "straight shooters" in all around good service and making repairs necessary to keep the unit running well. When the unit started to fail on Friday, Brandon did a proposal for the new unit. I got a quote from another big AC company in the Valley, which was about $1000 less money and longer warranty coverage. I decided to stay with the company that has been showing up with consistently good service for the past 16 years--Wolff. This morning Brandon responded to my text, and came around noon to finalize the measurements, paperwork and financing, also bringing a loaner portable AC so I don't have to go to a hotel. Chris promised to fit me in sooner in the case of a cancellation or shorter day which would mean they could take care of everything sooner. (Dogs are in kennel, also a costly solution but worth it to keep them safe.) In spite of the heat and inconvenience of a broken AC, I'm optimistic this will work out well, and have confidence working with a company that seems to do what it says it will do. Thank you Wolff!

• I have used Wolff Mechanical for many years to install and maintain HVAC on both residential and rental properties. When working over so many years, there are bound to be mechanical issues from time to time, but they always remedy the problems with special care to make sure they leave the customer with what they need. My current experience was a project that was a little different than usual. I was preparing to replace a flat roof that had three a/c units; two which needed various tasks to get them ready for the new roof. One of the units had not been installed by Wolff and needed special attention. Brandon planned the project to make sure we had the most efficient use of crane time, the right materials ready to go and a schedule that would beat the roofers to the job! Brandon and Derrick quickly and efficiently completed the project so the everything was ready for the roofers. I am sold on using Wolff Mechanical for my HVAC needs but this latest project reinforced the reasons why. Thanks Office folks who took my calls about scheduling and to Brandon and Derrick for excellent, professional work.

• Derrick is highly qualified, experienced, knowledgeable, and has a great personality and customer orientation. Really appreciate working with Derek and Wolff.

  Len K.★★★★★

• Wolff has taken care of my AC now on 3 occasions. My unit was old and I chose to replace it this last time. Absolutely the best customer service and quickest new unit install I've ever heard of. Well deserved 5 stars for the whole team.

  Leslie G.★★★★★

• I have been using Wolff for commercial repair and maintenance across multiple properties and have consistently experienced exceptional service. Their team of caring and professional individuals goes above and beyond to ensure each project is handled with precision. As a regular customer, I appreciate their prompt responses and fair pricing. I highly recommend Wolff for all your commercial HVAC needs.

  DM A.★★★★★

• Richard was awesome. He has been taking care of our family’s AC needs for years and we wouldn’t have anyone else. Trustworthy and knowledgeable!

  Audrey★★★★★

• Very kind, honest and fast service! Brandon was great thank you!!!

  julie D.★★★★★

• Absolutely the best in the Valley! When our old air conditioner died last month, we got three estimates to replace. Only Wolff's Brandon went up in the attic and did an extensive evaluation of our current system. (on an extremely hot day!)My husband did HVAC work in his younger days and he knew the original ductwork was not working correctly. Brandon identified the problem and gave us a complete estimate with duct work mods, including model numbers of the equipment we were getting. No one else did that. Installation is complete and there were no cost surprises. Our estimate and final bill were the same. Their installation crew worked efficiently and did a great cleanup and removal of our old system and ducts. This is now the 4th system Wolff has done for our family members in the valley and there has not been one issue with any of them. I highly recommend them.
