Wolff Mechanical is always extremely professional and can match or beat any other air conditioning company prices. They're beyond courteous when they are in our home, clean up after themselves and always knock before entering rooms and the house. We love them and will continue to use them as long as we're in Arizona! read more

I have been a customer of Wolff Mechanical for almost 8 years. During that time I have both purchased new Trane systems for two homes as well as contracting for their annual service contracts. Trust worthy professional and customer oriented describe them them to a T. Today they also added responsible to that list. They took responsibility for a mistake that they could have easily denied. The result was a significant amount of rework at their expense. No doubt they have a customer for life. read more

This is the best company to hire. I have been using them for almost 8 years. They are always on time, courteous and professional. They wear company identifying shirts and drive vans/trucks with the company name on them. The technicians have all been knowledgeable about my A/C units and never try to "up sell" parts or units. You can be sure of fair treatment with Wolff. read more

After getting screwed by Goettl Air Conditioning (who is under heat from Arizona's Att. General for deceptive advertising...see here: http://www.azcentral.com/business/articles/2011/09/15/20110915arizona-suing-shut-down-goettl.html Wolff Mechanical was a breath of fresh air. Great customer service, fair prices and they DID NOT LIE. Check them out: http://azairconditioning.com/ read more

My heat pump started blowing cool a few days ago. After another company came out and estimated it would take $2000 to repair my system (and recommended that I buy another one) I called Wolff for a second opinion. I was referred to them by one of my family members. One of their guys came out today and spent quite a bit of time on my roof before coming down and telling me what the problem was. He said that aside from being an old system, the only thing wrong with it was that it was 4 pounds low on refrigerant. This was a stark contrast from the first company that came out, who said that I was out of refrigerant, there was a refrigerant leak needed to be fixed, and two other pieces were broken. When I heard that the only issue was being low on refrigerant (and that the price they quoted me per pound was $30 cheaper) I was very relieved. The tech filled it up within 15 minutes and my house was warm again. I'm really glad I called Wolff for a second opinion, and that I didn't get grifted (as it seemed the other company was certainly trying to do). I'll certainly be calling Wolff again in the future when things go wrong and recommend them to my friends and family as well. read more

I've had an annual contract with Wolff for a few years and they come out 2x a year to check gas heating and A/C and make any needed repairs which have never been very serious ($400 at the most probably). Customer Service is always great, the techs are knowledgeable too and do good work. My 2 single-stage systems of course were aging and I knew the time would come where I would have to put them down. This year, at age 13, the tech delivered the bad news that it was time. I have 2 A/C-gas furnace systems (original builder grade Goodmans and noisey!). Of course I got more than 1 estimate. Decided on Wolff. My sales person, Brandon DuBois, was outstanding, highly professional, eager, likes his job, likes his company, likes people, knows his 'stuff'; and the company offered good financing, etc. Went with the 2-stage 16 seer Daikin; 2400 square foot 2-level house. Easily scheduled the work to be done within a short time frame out, and because I work they came out on a Saturday. Two crews were sent to get the job done in 1 day. The team leader, Zaid, was meticulous, knowledgeable and concerned. The crew worked great together, too. Zaid didn't leave the job until he was sure the 2 systems were working optimally. I know have 2 beautiful, more quiet systems, more cost effective systems with a best-in-class warranty and Wi-Fi enabled programmable thermostats, just in time for summer! If you're looking especially to replace your systems, definitely consider Wolff for one of your estimates. And if you're looking to make sure your systems continue running, also considering Wolff for their annual contract. The 2 annual check ups are free and any service or repair needed is done at a discount. read more

I will never contact Wolff mechanical for business again and I recommend you finding someone else to fix your air conditioning. It took them a week to fix my air, A WEEK. No apologies from the actually company, just the repair who causally said "sorry this took so long". It was something simple as the external rotating fan. And once they finally got around to actually fixing it, they were missing another part, which they "never have ran out of before" which then took another two days for them to come out again. We called them every time asking for updates or to set up times, not once did they initiate the call. Please choose another company to fix your air. Unless you want to be displaced from your home for a week. read more

When my husband and I just wanted to discuss a possible new AC/HEAT unit in about 6 months, Christine in sales at Wolff was so pushy, rude and aggressive. I have used Wolff on three prior homes we have owned and after dealing with Christine we will not return in any way, shape or form. She is incredibly rude and does not have the customer's needs at heart. I was shocked at her unprofessional manner. We are going somewhere else for service AND purchasing a new AC unit. read more

I contacted Wolff Mechanical because they were an authorized APS contractor to conduct a super-tune up on my ac. They came out, and their machine wasn't working to conduct the audit, so they left. They never followed up to reschedule, and they left a mess in my house from going up into the attic. I will never recommend them to anyone. read more

We will never use another AC company. We had several AC companies try to fix our old unit, and we felt Wolff was always honest and reasonably priced. Our regular tech, Dave, was always knowledgeable and took pride in his work. Wolff even came out on 9 pm on a Saturday night within an hour after we called to fix our broken unit. Eventually, when we had yet another problem with our old unit during an extreme heat wave, Wolff gave us the option to repair or replace the unit. We felt the quote to replace the AC was fair and because we trusted Wolff, we went ahead with the replacement without getting other quotes. Wolff installed our unit the next day and the follow up has been great. read more

I appreciate these guys so unbelievably much for handling their air conditioning business the way they do! They are professional, knowledgable, hard working, and ethical. I would recommend them to anyone and would never hesitate to call them again in the future. read more

This company is amazing! We had issues with our A/C undergoing a power outage daily while we were at work. We called and they sent someone out the same night and he spent over 2.5 hours working on it and when he left it was up and running. However, the next day the same thing happened so we called again and Jason came later that day. He spent another hour or so working on it and solved the problem and thoroughly explained everything to me. He didn't charge us for the labor he did (which was extensive) and he was very professional! I would highly recommend this company to anyone. They were so reliable and timely which is important when it's 115 degrees out! Thank you Wolff Mechanical! read more

Our roof mounted heat pump starting making a loud hissing or screeching type sound Saturday morning, so I immediately turned the unit off and contacted Wolff Mechanical for a service call. I was happy to see their technician, at our door within an hour after the call. I explained the symptoms to him, and recommended he get on the roof before I turned the unit back on, and he agreed. As soon as I turned the unit on, it started making the noise, and the technician removed power at the disconnect on the side of the unit. He came down off the roof, explained the blower unit and motor was bad, and he would need some time to work up an estimate. When he came to the door 10 minutes or so later, he started in with the fact that the unit is 19 years old, and we should consider replacement, and repair at this point would be $1200+ to fix the blower unit and motor. Additionally, as luck would have it, the necessary parts were not available, would need to be ordered from Trane, and the parts would not be available until Monday or Tuesday. He was leaving us with no air conditioning for three days! At that point, he recommended he call the sales person to come price out a new system to get things moving faster come Monday, should we decide to replace the unit. The sales person on call was not available, so we postponed. I was charged their standard $89 service fee, + $1 to be upgraded to, as it was explained, Wolff Service. I was told the estimate and the receipt would be provided in email. The receipt was, BUT THE ESTIMATE WAS NOT, AND NO HARD COPY WAS LEFT WITH ME. I immediately called another company, and they also had their technician arrive promptly, considering it was a Saturday. After he spent about 20 minutes on the roof he said the unit was fixed! He found the squirrel cage came loose from the motor shaft, and that it just needed to be put back in place, and a set screw re-tightened. I had told him of the visit from Wolff Mechanical, and he informed me that there was no evidence that any of the panels on the unit had been removed before his arrival. The technician from Wolff never even looked at our system!! It appears that our $90 was to pay for his psychic abilities, as he was able to trouble shoot without even removing the panels. So from my perspective, the Wolff technician lied to us, gave us an outrageous quote, and tried to sway us into replacing our unit instead of repairing the problem. He was going to leave us with no A/C for three days in the summer heat, giving me no choice but to move my wife and dog into a hotel for the duration until repairs and/or a replacement could be done. He played upon the fact that our system is 19 years old, so who would question the logic that it's probably time to get a new unit?! I feel that the Wolff technician saw us as an easy target. What bothers me the most, is that he smiled the whole time he lied to us and tried to swindle us! I will not be recommending Wolff Mechanical service to anyone. read more

This is a company that I have been using for my A/C needs for some time. Usually I am very happy with the price and the service they provide but this last visit was so appallingly bad that I don't know if I would ever use them again. I don't know if they changed owners or if this was just a really bad day for a new tech but I was very disappointed. Tech showed up, took a quick look at the exterior part of my system and said something was terribly wrong with it because it was only cooling 4 degrees at the unit. He looked at few things, took his sniffer thing up in the attic and said it had a micro leak at the evap coil. He explained to me that this would cost 2800-3500 dollars to fix, recommended I replace the entire system and gave me a quote of 9500 to 11,500 dollars to do so. His report indicated that the unit was so low on refrigerant that he was unable to complete the check, and where the leak was on the coil. I wanted to price a new coil so I went up a couple days later to get a model number and found the tech had left some of the screws out so that the unit had a 1/2 inch open gap that leaked air when it was running. Bear in mind the heater functions fine, except that now I pay to heat my attic as well as the house because their tech did not bother with re-assembling my unit when he was done!!!! Enter the next company that I called out for a second opinion. Ran the unit for a while, tested all the temperatures out and the came out right in range for proper operation (18 degree drop, which is at the lower end but acceptable). He then got his sniffer out and tested for leaks, both where the Wolff Tech said and all around the attic unit. Nothing. No leaks. He did recommend I add a little Freon, but it did not need much at all, they say it was little enough that it could easily be accounted for by what is lost from annual checks and maybe started a bit low when compressor was replaced but no big deal. Bottom line? There was never anything wrong with my unit at all!!! Nothing. What the hell happened here? If I had listened to that Wolff tech and replaced my system I would have spent as much as 11,500 dollars to replace something that is working normally. If I had not checked their work I could have ended up paying to air condition my attic all summer because they didn't put my system back together properly. BE VERY CAREFUL IN TRUSTING THIS COMPANY!!!!!!!!!!!!! read more

I'm very impressed with the customer service, response and work completed on my unit. This morning I woke up and decided to install my Nest thermostat. Somehow in the process I lost power to the A/C and furnace and was unable to complete the process. I contacted Nest who attempted to troubleshoot the problem but was unsuccessful. They provided me with a list of technicians and I chose Wolff Mechanical. I gave them a phone call and spoke with Crystal. She advised me that today was a busy day for them but she could fit me in somewhere between 2-6. This would have worked but I had a prior engagement that I needed to attend at 6. I advised Crystal of my situation and she said she would do her best to get me in by 5 but no promises. Within the hour, I received a call from Crystal and she advised that a technician could be at my house within 45 minutes. Perfect!! Great work Crystal!! This may not seem like a big deal to most but when you consider all circumstances, prior engagement and I live in the desert and it may reach 100 degrees today. Getting my unit up and running was very important. It's nice to know that Crystal went above and beyond to accommodate me. The Technician (I can't remember his name) was very professional, quick and provided me with important information about my units that I did not know. He repaired my unit, showed me the part he replaced and thanked me for choosing his company. Good fast service is hard to come by and I would recommend this company to anyone. read more

I had a problem with my gas heat- no heat or flow in one zone of the house. I called Wolff for service. I do have an old two zone heating/AC system with the heater in the attic. The tech promptly came, and went up in the attic and said the limit switches are weak and he has adjusted them, and it will work. He said it takes an hour or more for me to feel the heat. He recommended a new system, and gave me a detailed quote for a new system, strongly pushing it. He also charged me $160 for the service call. After he left, there was no heat even after a few hours. I reluctantly went up on the attic myself to check, and found that the duct system that connects to the heater was completely disconnected and the duct was lying on the floor, with nice hot air spewing into the attic. I reconnected it and secured it with duct tape, and lo and behold, got heat in the house immediately. I am unhappy that I was charged $160, though the problem was obvious and unattended to; the tech was only interested in trying to sign me up for a new system. I needed to replace my old system, but chose another company based on this experience. I hope this was an an isolated problem since i do see good reviews from others. read more

If I could give 0 stars, I would. The first time I arranged for a service person to come out to check my air conditioner they gave me a 4 hour window for arrival. After 3 hours and 30 minutes I called the company and was told that my appointment was cancelled (without asking or telling me) because "other people with broken air conditioners needed their services more." Very unhappy, I rescheduled to a different day with a morning 4 hour window, since I have a standing work appointment in the afternoon. After 3 hours I called to check on my appointment and was told that I was scheduled for the afternoon 4 hour window. I had it written down on 3 calendars, and remember well the conversation with the scheduler telling him I needed my appointment in the morning and him agreeing to it. In fact, I moved my appointment out a few days specifically so I could have the morning block of time. I have taken off work a total of 8 hours without results. Wish I had learned the first time and gone with another company instead of rescheduling. read more

I purchased a new rooftop ac unit from Wolff Mechanical a year ago. I found them when I needed someone to do a hail inspection on my ac unit. They were very helpful in assisting me to make a hail claim through my insurance company. Long story short, my insurance didn't pay for the hail damage, so I had to purchase the new system myself. After getting quotes form other companies Wolff was the best value. Now a year and a couple weeks after they installed the unit, it all of the sudden stopped working out of the blue last night at about 8:00pm. I went to Wolff's website and called the number thinking I would leave a message for someone to call me back the next day. To my surprise someone answered. I explained the problem and she said she would have someone call me back. About 10 minutes later a tech called me and said that he could be there in about an hour to fix it. This would be at 9:00pm! I was amazed. After the tech arrived it was determined that it was the thermostat that was bad. He asked to see my initial install paperwork. When I showed it to him he noticed that the system was actually 2 weeks past warranty. He quickly said "no problem, I'll make the warranty retroactive and cover it". These guys are top notch! where a lot of companies would just show up when it was convenient for them and stick you with the cost of repairs the day after the warranty expires, Wolff values their customers enough to make getting their system back working again a priority and stands behind their work! I would highly recommend them! read more

Buyer Beware! We were excited to get a new and efficient A/C system upgrade from Wolff Mechanical, but the experience has not come close to living up to our expectations. Our new $11k+ system was installed in Feb 2017. In June of 2017 we started to have the first issues as temperatures reached 110+ degrees. Our system stopped cooling our home and our indoor temperatures became very uncomfortable. Being a brand new and expensive system, we expected Wolff to respond to our issues with vigor and urgency - especially given that we had a 12-yr warranty on the new system. Instead, we were met with unresponsive customer service, unreliable information and a situation filled with frustration. After numerous calls and visits we have been told that the sensor in the expensive (upgraded) unit that we purchased does not work properly when temperatures reach over 110+ degrees. So Wolff Mechanical sold us a product that doesn't work here in Phoenix when it is needed most! However, the most disappointing part of the experience is that Wolff Mechanical has been unresponsive to our issue, to the point where our calls were going unanswered and messages not responded to -- we are forced to call multiple times to get help instead of getting "promised" calls back. We continue to work with them to find resolution, but we are struggling through these days of extreme heat where our brand new $11k+ Wolff sold & install A/C system is not working. Please be careful dealing with this company. read more
