Awful awful, starting from Barbara (the receptionist) up to the manager on call. We had AC issues on a Friday after they installed one of the AC units improperly (6 months ago). We called and they promised to send someone out but no one came. We called again and Barbara stated that they weren't able to have anyone come out until Monday --the entire weekend with the house in greate85 degree heat (the other Ac unit set at 60 and trying to cool all parts of the house). I have 2 small children, aged 2 and 7. Never go to Wolff, we are reporting them to the BBB. Awful! Paul, the owner called us and sorted things out. He listened to our concerns and addressed them the very same day! We are so appreciative, we decided to stay with Wolff for continued maintenance. Brandon, their technician was professional, knowledgeable and fixed the Ac right away! Thank you Paul for making us feel valued as customers! read more

Buyer Beware -- Bottom-Line Driven, Questionable Workmanship First, some context: over the last 12 months, I've interacted with 10+ HVAC companies here in the Valley, and my general take is that many of them are almost as bad as used car salesmen. So what I'm about to share about Wolff Mechanical may well be industry standard lol. I bought my home from my neighbor in October 2020. I'm good friends with the previous owner, and he had purchased the current AC system in April 2018 -- installed by Wolff Mechanical. A couple of weeks ago, I had an issue with the system, so naturally I called Wolff. After several confusing phone calls between Wolff and Daikin, I learned that my system was fully covered under an extended 12-year parts and labor warranty. Great news -- or so I thought. When I began to move forward with the warranty work through Wolff, I was told everything was covered except the refrigerant. Wolff charges $150 per pound, and my unit would need 6-12 pounds. I asked the rep directly: "So even though the system is fully covered, you're still going to charge me somewhere between $900 and $1,800 to put refrigerant in it?" I asked if the price was negotiable. He said, "Not really." Wolff's position was essentially, "This is industry standard" -- meaning everyone charges this much, so they do too. This felt ridiculous to me. It's the equivalent of taking your car in for a warranty transmission replacement and being told you owe $1,000 for transmission fluid. So I did my own research. Turns out the refrigerant can be purchased for a fraction of $150 per pound -- Wolff appears to be marking it up by several hundred percent. I also learned that Daikin actually does cover refrigerant under the warranty, up to $100, which is a far more reasonable number. I called around and found Emergency Air. The experience was completely different. They didn't try to charge me separately for refrigerant. They said it was covered under the warranty (which it is -- just not at $150 a pound). Emergency Air completed the warranty work, and in the process they discovered a leak in one of the duct connections at the plenum. Their assessment: the original installer (Wolff) tried to connect the duct to the plenum, it didn't fit quite right, and instead of starting over and doing it correctly, they slapped a "band-aid" on it with tape to save time. I can't prove this was Wolff's workmanship, but I've never had any other techs work on the plenum since I've owned the house, and the previous owner confirmed Wolff was the only company he used during his two years of ownership. I called Wolff and asked if they'd come out to make it right. Yes, it's been eight years -- but if it was their faulty installation, I felt they should stand behind it. The person who answered checked with someone and came back with a no. They'd charge $160 just to come look at it, plus whatever the repair cost. Disappointing, but fine. I then expressed my overall dissatisfaction with the experience. The conversation got defensive, I got frustrated, and the call ended poorly. I called back to log a formal complaint and was told, "Here's the email address. Do whatever you have to do." A more senior employee eventually called me back. He was more tactful, but the answer was the same: "We're not going to come back out eight years after the fact to repair something." He said they'd have internal discussions about the customer service issues I raised. So -- be careful doing business with Wolff Mechanical. My perception is that their attitude is essentially "all HVAC contractors operate like this, so we do too." Their workmanship, in my case at least, appears to have been subpar. Not once did anyone express genuine concern or say, "Maybe we can work with you on this." My experience is that they're heavily bottom-line driven and far less focused on customer satisfaction -- it's about covering their costs, minimizing their risks, and maximizing revenue, not about making the customer happy. And don't fall for the "$150 per pound" refrigerant line. Yes, the large HVAC contractors may all do it -- but it's a significant markup, and there are companies out there that will cover it under warranty at no cost to you. read more

Also have been a loyal customer of Wolff for many years and am extremely frustrated with their customer service approach. Trane a/c compressor under two years old (still under warranty) that they installed died/malfunctioned. I can accept that. Make good on the faulty product sold and installed. We are going on three weeks supposedly waiting for a new Trane compressor to arrive from China is all I'm being told. No apology or any warmth for the inconvenience or any sense of urgency to get this customer up and running as 100* temps return. Asked the service manager, Chris, if he thought the compressor might arrive by July !! Think about installing a new compressor other than Trane to make the customer happy and honor the warranty ??? Told they would absolutely not do that. I was told "it was no fault of ours that the compressor broke." A service manager does not say that to a customer if you actually care. Lame !!! read more

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. read more

I have been a loyal customer of Wollf Mechanical for many many years. I've always been happy with the service calls. I have a regular maintenance account with them, and I even bought a new AC-Gas unit through them some years ago. I tried writing a private complaint on the WM website, but the contact webpage just buffers after I write my message (another complaint). So I have to resort to this public forum. My complaint is about the phone receptionist Cheryl. Her conversational manner is brusque, officious, and off-putting. She acts like she is in charge of the conversation instead of the customer. Instead of asking if I wanted to pay month by month, which I did last year, to renew the maintenance contract, she just charged for the whole year. But it's really her tone that is annoying. I want to feel helped instead of being made to feel that she's in charge and I have to prove myself to her that I deserve answers. She asks me to check my records before she checks the company's! I told her all this in our last conversation. Her response was the passive-agressive "I'm sorry you feel that way." read more

Highly Recommend this company. They are Great from the Salesman Brandon to the technicians to Elizabeth from inside. They delivered everything they promised and were clean and courteous and well organized. Thanks for the great work. Bravo. read more

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! read more

Drivers should not drive down the turning lane because they don't want to wait. Unsafe and luckily no one was hurt. Truck number 86.

I have been a loyal VIP customer for over 8 years. They have shown horrible customer service, and sent out inept workers. Tried arguing with me when I stated the problem. Then when I asked them NOT to resend a particular technician out to me, who do they send ? The very same individual. I will be switching to another company asap. Awful... -------- **** update to my experience described above... Many thanks to Paul Kuiper gen manager for making proper ammends and doing the right thing. He was certainly correct in saying that these events 'are not the Wolff way'. Hopefully some of the other folks will take some lessons in customer service from Paul. Regardless, I do very much appreciate Paul making the best out of this situation. We are going to continue working with Wolff. read more

Thank you to Joey and Joe V. for figuring out my complex AC issue. Wolff Technicians are the most experienced, honest and all around just great guys. They will always go above and beyond to assist you and fix your issue as Joey and Joe V did for me. They will not let you down. Wolff Mechanical should be your only choice when it comes to your AC unit/Service/issues. read more

What outstanding customer service from Joe V. and his boss. Came out at 5:30 pm and worked hard for hours to get my AC running. Wolff is honest, reliable and they are focused on doing the job correctly, honestly and efficiently. Most importantly they care about their customers. A great company for all your needs, you can trust them 100%. read more

Interesting morning. Sitting at a red light and one of their drivers is honking at me like a maniac. Sorry I wasn't going to run a red because you were late. I call the number on the van to tell customer service their driver is out of control and making their company look bad. She asks me for my name. I ask her why that's relevant and to let me give her the number on the back of this drivers van. She refuses to take the number and will not listen to the issue. At one point she asks me again for my name (what are you thinking)? At this point I ask if I can speak to a supervisor to give them this number on the van before I lose the driver. She then tells me my name is required. At this point the driver is gone so this is my only way to leave feedback to management. I was simply trying to report a maniac driver and unable to do so due to the customer service representative. She was definitely the worst I have ever spoken with and she was trying to talk over me. I am not sure what is so hard about answering a call and taking down a number and reporting the activity? Apparently too hard for this customer service rep. I hope you guys record your calls to back and listen on 7am on 8/20/19. My current belief is I must have called a small shop and reported the husband to the wife or something No real explanation but stay away from these guys on the roads and stay away from calling their front desk. Prolly would stay away in general. Unreal experience this morning and I rarely ever leave a review. I hope Management sees an actions but I have a feeling management was the guy honking at me this morning trying to run a red light. read more

I have been a loyal customer to them for almost 15 years now with both my businesses and my residential homes. I have probably spent over $150,000 with their company within those years and they just lost me as a customer for life time over $90. Their integrity and ethics have lowered immensely and I will never use them again. read more

Our HVAC was not producing cool air. We tried replacing the air filter and switched the main breaker switch several times, to no avail. Called Wolff Mechanical for repair service and Richard, our service rep from Wolff's arrived (ahead of schedule) and was able to diagnose the problem without having to enter our home. In less than an hour, we were "chillin' " again! Thank you, Richard! read more

July 27th. Update...AC is still blowing cold and working great!! Thanks again!! Came home Tuesday to AC blowing hot air. Called another company, got them out ASAP, which was Wednesday afternoon(today). Turned off AC Tuesday, back on two hours later and was blowing cold air. Wednesday, AC blowing cold all day, but still need unit inspected/serviced, kept our appt. Service tech arrives, inspects our AC. Informs us a repair of $4400 will be required, as this unit will not last the summer(unit is about 12 years old) even with it currently working. Wanting a second opinion, called Wolff at 6:45 PM on Wednesday(today) wanting to set up an appt for tomorrow. Spoke with a gentleman, believe Andreus, who was very pleasant. Informed him of what I needed, he offered SAME DAY to have a service tech out. I informed him I didn't want to be an inconvenience, he reassured me "not at all." Perfect, told me worst case, someone would be by before 8:30 PM. Received a call from Jason, at 7:04 PM, let me know he'd be here with in 30 minutes, traffic permitting. Jason arrives, within his stated time frame. Introduces himself with a smile and handshake, and I tell him what's going on (AC blew hot yesterday, turned it off 2 hours, been cold since), he's replies "let me gear up and I'll see what's going on." Jason is on my roof for over an hour, has my hose up there, and is doing his thing. Climbs down, and gives me the run down. Let's me know system is working as intended, and he found system was over charged. He filled the refrigerant to the correct level. Tells me it is an old unit, so replacement will be needed sooner than later, but after I asked him about it lasting the summer, he informed me he didn't see why it shouldn't make it. Awesome! $200 later, AC is running cold, I feel confident in Jason's assessment, and when I do need a new unit, Wolff will be the folks doing the replacement. Thank you again guys. read more

Awful is a good word for their business. In 18 months time they over billed by $17,000+. They "looked into it" and said they only over billed by $8,000+. This was a commercial account and we spent over $300,000. I would not recommend this company! read more

Dwayne called first and arrived as stated and performed a preventive maintenance check-up on my unit. He was friendly, very professional, and documentation was thorough. Highly recommend. read more

I was referred to Wolff Mechanical by my Mom. We had 4 different companies come out and give us an estimate for our AC which needed to be replaced. The first quote was from George Brazil and they wanted $6,800-$7,500 to complete the task. Highway robbery. There were 2 companies that requested a much more reasonable price...just over $5000. We decided to go with Wolff because they offered a 12 yr warranty and a $250 rebate through APS, not to mention a lower price. Also, let's face it, I respect my parent's opinion and they have been using Wolff Mechanical for many years. Mike Stoffer, A.K.A. Comfort Consultant, was truly amazing from start to finish. He came out on Friday and we had our AC blowing cold on Monday. He authorized the installation even though he knew we would not be able to pay until the next day while funds were being transferred into our account. Then when we did have the check filled out, he personally came back to our house to pick it up. I recommend Wolff Mechanical to anyone who wants an honest and reliable AC Company!!! Bar-none. read more

We bought an AC unit for a wine cellar from Wolff mechanical and they installed it without issue. Yearly, they come and complete their routine preventative maintenance (PM) and we haven't had an issue until now. We contacted them and they surprisingly said they no longer complete PM on the wine units they install. I can understand if a company informs the customer that they do not provide a service with a new install however, they should continue the service and not just tell us "we don't do that anymore". Poor customer service. read more

Wolff has installed three A/C units for me over the past few years. Each time they did a fantastic job and had the best pricing. Tim was great to work with. He took the time to understand my needs and find a solution to best meet those needs. The install teams were all great and very courteous. They took the time to plan ahead and as a result, I've been very pleased with their work. I'm pretty picky with my installs and check each one after they are installed for overall workmanship, leaks (small and big throughout the system), temperature differentials (e.g. it heats and cools to specifications) and the work area is clean and free of debris. When something is not perfect, they fix it that day or the next. I would highly recommend the team at Wolff for your next install or service. read more

After installing a brand new unit, our air stopped at 10PM that night. Their 24 hour service consists of an answering service after 10PM. We had the sales rep's cell number though and she got a hold of the installation manager. He let us know that they would pickup a hotel room and that we should not feel obligated to stay in the house in the heat. They sent a reimbursement for the room and took care of us. I am not thrilled about the inconvenience and it uncovered an opportunity for improvement but they took care of everything and made sure it worked. In this world, it's not if you make a mistake, it's how you address the error and grow from it. Wolff made it right and everything worked out in the end. read more

Had them install our AC system 7 years ago and the past few years have had problems. First the fan came off. They said this sometimes happens and it was not covered under warranty. Funny how they did the install and have done all of the service and maintenance, but sometimes this happens? On the latest issue we called them as the unit was not cooling. The first technician arrives and tells us he can not go on the roof and check out it out as he is recovering from surgery. We told them the unit was on a steep pitched roof and they send someone out that can't go on a roof. After calling they sent out another tech (Kenneth - great guy, professional 5 stars for him) who took care of the issue (another item that should have been covered by warranty due to improper installation. They told us the manager would call us on Monday, but we never got a call. Guess they don't want our business, bye! read more

They shouldn't even get one star, but not a choice. After multiple calls overnight, they never called back nor stated they don't do overnight emergency calls. Website states they are 24/7, not true. Search elsewhere if you have an actual emergency. They don't even care if it's a medical emergency. read more

Having had issues with air-conditioner installations in the past I've waited for a year to write this review. I wanted to make sure that everything that was installed worked correctly and when dealing with an air-conditioner, it takes all the seasons to really know. I'm happy to say that everything they said about the unit they sold me and the installation came out fine. They were professional about everything and the installation went without a hitch. I highly recommend Wolff if you need your air-conditioner replaced or even if you just need service. We had been using them for service on our old unit and even though we checked around before using them for the purchase and installation of a new unit, they turned out to be the best price and we could get a year interest free financing. We're happy with Wolff. read more

Technicians came and sealed up some holes in duct work and cleaned coils on AC. They did a complete and thorough job and they even vacuumed up the insulation from my floors. Excellent service and on time too. read more

I have been a good customer for Wolff for 22 years but my latest dealings with them has changed my opinion. I called for a problem with one of my ac units and the tech said I needed new parts which were under warranty. He would order them and have the work done in a week. I approved the work but had to leave town. I returned 6 weeks later to find no work done and my house at 100o. They were to install a new unit on the other side of my house but during the process said there was a gas line problem and I had to call another plumber to fix it. Their people are the only ones that have ever been in my attic yet they took no responsibility for the bent flex line. I found the techs professional and very courteous and friendly but it ends there. read more

Wow. I called Wolff to have them estimate installation of 2 whole home humidifier units since they show up as an Aprilaire contractor. They first wanted to ask if I understood these might cost as much as $5000 each since they might have to bring in an electrician and a plumber. Talk about hair standing up on my neck! Folks, the Humidifier Units cost $200 each. If their own people cannot do basic electrical and plumbing work, these guys are not a "Mechanical AC, Heat and Solar" company. $5000 each for installation of a $200 humidifier? Nice try Wolff, but you won't be stepping foot on my property. LOL... read more

We've used Wolff for years, our last annual contract with them for ac/heat checks ended, and we won't use them again. More expensive than competitors, and terrible customer service. Our last attempts at scheduling ended with a tech showing up 4 hours early, a tech not showing up at all, and a smart-alec phone rep who was unapologetic. I called last month to see if I could refund the remainder on the contract, the guy on the phone said 'no way, and if you wanted to it's above my pay grade.' I guess that means if the contract expires you lose tour pre-payment. There's far better companies doing it out there for less. read more

Tim was very professional and explained everything very well. I researched and found the A+ BBB rating and that they have been in business for over 25 years. I did not feel pressured or sold to, and I even cancelled another company as I found better service and professionalism with Wolff. He even gave me a sheet that compared systems in columns and broke down the cost. It helped me make my decision and not feel taken advantage of and helped me compare. In the end, I felt like I was making a more educated decision. They install tomorrow. I will update then. Update: They came as scheduled this morning. Three men all very nice, professional amd efficient. I am pleased with the heating system. It blows much better than what I had. It is quiet. Also, because it blows well, I think I will be able to have the heat set to lower temp (and hopefully in summer the AC set higher temp). They explained how to use my new thermostat. They used booties when in the house and then put canvas down to cover the carper foe hauling stuff in and out. They even vacuumed up afterwards. Great experience. read more

Honestly, I admit I am not the home owner who hired Wolff. I am however the person who has been home when they've come to service, twice. I think they're great! I came home and was experiencing issues with the unit it was 5:30 pm, they managed to send David to help me out and fortunately they sent him within hours of my call. He was kind and repaired my unit. The previous gentleman who came to help a while ago was also very kind and also fixed the unit and I believe it was also the same day. These guys are my fave :-) thank you for your kind prompt a/c servicing :-) read more

A+ for ethics A Wolff tech diagnosed our A/C issue as "overcharged" and found the system had "non condensables." The cure, evacuate and recharge the system at a cost of almost $1,400. Here is where the ethics comes in to play. The technician's next words were, "Do you have a home warranty?" We do so the technician stopped and recommended we call the home warranty company. Home warranty should pay for the service. Rather than charge me for a service he could have performed, the technician put my interests, and wallet first. As a sidebar note, the Wolff technician told me that he and other techs at Wolff are paid salary. Other companies pay commission on services performed. I do not know if this is true, but will ask the question when I seek the services of other trades. read more

I have tried to call Marty Wolf and I am always told he isn't in. I have left voicemail and he never returns the call. I have to have an annual service to maintain my warranty. He raised my annual inspection by 30%. Never told me it was being raised until service mech came out and handed me a bill. Did less on the service than year before and raised invoice by 30%. I will never recommend this company to anyone. read more

If there is anything I hate is someone charging me when they didn't do a damn thing. My heater part of my a/c went out 2 years ago when we got that freeze. So I called my warranty company and they recommended Wolff Mechanical, so they came out cause no one else was available. Just so happen when they came out, they determined nothing was wrong with the unit eventhough my girlfriend was sick and it was ice cold in my house. They still charged me for the service call, but told me to call them back when it happend again. So less than an hour later, I called them back and they came out and said that everything was fine and was about to leave and I demanded I get some answer. Unfortunately, of course everything was just fine, but I was freezing my ass off and will never call them again and will tell everyone I know never to call Wolff Mechanical. read more

My family's been using Wolff to service and maintain our HVAC system for years, and we've always found them to be professional, reasonably priced, and honest. We've had the occasional tech who's a little wet behind the ears, but even they've just taken a little longer to do the same work. read more

I called Wolff for an estimate on getting Solar AC units was told that Daikin unit were better and more economical. Well Mike came out to my home gave me the tour on how I would save money on these unit and no cost for service .I said that is awesome BUT I do not want to have a finance payment that is going to be bigger than my average electric bill. So here is what it will cost to replace my units Daikin HH (2) DZ20VC0481A Variable Speed Heat Pumps 7958771 (2) 4 Ton 20.0 / 12.5 Daikin (2) DV48PVCD14A Variable Speed Air Handlers - - - Daikin (2) Comfort Net (CTK04) Controllers & Bridge this totaled 27k OMG....... What the H*** Why would I want a finance payment of $251 per month. I pay for a full year of electric $2,994.15 if you divide 12 months $249 per month..... So they said it would save up to 50% of my bill. Lets be conservative an say the systems are so good they do 55% That would mean I would save $137 WOW..... So that means I have to pay $251 + $112 = $363 a month....... I spent more to save...... Do yourself a favor WOLFF give a estimated price first instead of wasting my time. Now I asked for SOLAR WHY???? when using the SUN there is no electric be used and then my ELECTRIC bill is LESS.... WOW what a concept.... Never got that Solar AC estimate......... As of today still waiting on that SOLAR ESTIMATE....... 11/22/2015 Still nothing from them on installing SOLAR AC read more

We love our new a/c from Wolff Mechanical. Our sales person and installation crew were both very professional. Can't believe we waited so long to upgrade our system. Wish we would have done so sooner. This unit is so quiet and has a two stage cooling system. It makes such a difference in our home! read more

I recently had Wolff Mechanical install 3 new a/c units and the furnaces/air handling units corresponding to them. The representative I worked with was Tim Friederich and he did an outstanding and thorough job of explaining everything they would do, suggested features I should consider and was very professional. In addition to Tim the installation crew (5) was very professional, friendly, prompt and left the areas perfect upon completion. From custom fabricating a piece to make a unit fit in a very tight spot to the overall look and operation of the units Wolff did a great job. Wolff Mechanical was one of 4 companies I met with and received quotes--they were not the least expensive but they were the one I was most comfortable with--largely due to Tim. I am very satisfied.
