Good timely service

After being told by 2 companies that I would need a total system replacement they sent out a manager to evaluate my system. They found a small leak in the heat pump fixed it, recharged the system, made some mechanical and thermostat adjustments and it's been working for nine months. Scheduling the service was also good.

ACE Temperature always satisfies with Customer oriented Technician’s you can trust. The ACE Team has great experience and their jobs are always complete with Reliable confidence. John

As the Facilities Manager at Tufts University, I’m always looking for companies that can get equipment repaired or installed quickly without blowing the budget. Ace Temp has always gone above and beyond with their friendly, knowledgeable team and their willingness to work with us to stay within budget. I really appreciate all the great work they’ve done for us over the years and enjoy working with them.

This review is overdue as we’ve worked with ACE Temp Control for the past 7 years. We converted our entire commercial building to air source heat pump system. The process was not easy to say the least, but Mike and his team have been great both in terms of delivering cost effective solutions but also implementing seamlessly with the least amount of work interruption. I cannot thank them enough for their professionalism and commitment ; showing up when they say they’ll show up…scheduling the work around our schedule and our needs. I recommend them wholeheartedly. Thank you 🙏

I have been using Ace Temperature Control seems like forever, probably since the late 90's. They are the best. The office staff is always willing to help you when you call with an issue. All of the Technicians are knowledgeable and friendly and respectful of your house. I wouldn't use anyone else.

Ace is the best! Always punctual, they do great work, and respond quickly. I highly recommend them.

Beth A.
Ace has always shown up when I need them. I’ve called them a half dozen times in the past year and they have always been prompt and solution oriented. Should be your first call

Carter B.
Showed up when they said they were going to and fixed my True Kegerator. Happy!

My elderly friend has been giving the runaround on her getting her heater fix in her condo. All they do is ring up the bill and don t fix anything. Scammers!!!!!

Rolli C.
We spent over $50K with these guys and they incorrectly installed our system. Many problems. If you're installing a Mitsubishi system, get a Diamond Elite contractor. Your warranty will be longer and you'll get the work done right. These guys don't care; just want to bill you; never get to root cause of problems.

Glenn P.
Been using them for years. Reliable and professional!

Donald P.
High quality service.

Worst Customer service ever!! My 80 year old mother has been using this company for her AC startup and shutdown for over 10 years. She called for her spring startup appointment because they did not contact her. They have always had her scheduled twice a year for service. The woman who answered the phone told her she was too late to have the service done as they only do that in April/early May. My mother told her that she was never contacted for appt and wanted them to come out now, mid May. She was rudely told that they would not do that. The woman lied, saying that she tried to call her numerous times and there was no answering machine. This is an outright lie. I assume this lazy incompetent employee lied because she probably called once and it was busy and never tried again. She also could have sent an email or a letter asking my elderly mother to call to schedule an appointment. My mother called back twice to ask for the supervisor and was rudely told by the same woman there was none available. The woman told her she would have the supervisor call her back AND NO ONE EVER DID! Shame on you for being too lazy to do your job and for being so rude to an elderly woman! Ace Temperature Control has lost a loyal customer! I will never recommend this company to anyone.

CAUTIONARY TALE: I had brand new Central Air and Ductless Split systems installed in April of 2019 by Ace. We chose them mainly for the price, but they also seemed professional during our meetings and had decent reviews. Our AC stopped working on the FIRST hot day of 2019. Ace came out reluctantly after the woman who answers the phone was extremely rude and insisting that we would have to pay the weekend premium for a service call. As soon as the tech looked, he diagnosed that the installers had the drain pitched back into the Air Handler. Yes, the licensed HVAC installers had the drain dumping water back into the AC instead of outside. The tech was apologetic and acknowledged that the installers had screwed up the drain. He must have fixed the drain without checking the pitch of the rest of the unit. Fast forward to December of 2020 after the AC system had been off for over 2 months, water started POURING out of my ducts. We called Ace, and again the woman who answers the phone was extremely rude, and they NEVER CALLED BACK. I had a much more qualified person take a look and they determined that the entire AC Air Handler was pitched away from the drain and was filling all of my ducts with water for the last 2 cooling seasons. When he looked inside he was in disbelief and said "This is F****ed up. I've never seen this much water inside a system before" Not a good reaction when someone is looking at your 1.5 year old system. It took significant work to clean out all of the water in the system and ducts that had frozen several times in the cold temps. Don, the owner of Ace who chose to never call back after his employees screwed up so royally, is an unqualified hack who hires incompetent people (his family). When their shoddy work shows, they get defensive and attack the customer instead of correcting the issues they caused in the first place. Keep shopping for someone else!

Called in April of 2019, received a quote in September of 2019 and never heard back from them again. I called at least a dozen times to schedule an installation and never received a call back. I went with McDonald heating and cooling and couldn't be happier with them. Don't waste your time on this unprofessional company.

They provided me with awful service. I own an apartment; the technician diagnosed the incorrect compressor. They billed me 3 hours of labor to diagnose a bad fan motor on someone else’s HVAC system. First, I called and complained: “It doesn’t take 3 hours to diagnose a bad fan motor.” The manager, Sharlyne, called back the next business day and charged me for 1 hour instead. Sharlyne had an attitude and said: “You or I aren’t an HVAC tech...you don’t know how long it could take to diagnose a bad fan motor.” I’m an engineer and well informed on how long troubleshooting a fan compressor takes -anyways Sharlyne was rude. I went with a different company next and they informed me the prior company, Ace Temperature Control, incorrectly labeled the wrong HVAC unit and performed work on a system that wasn’t mine. I called Ace Temperature Control to get my refund and they haven’t granted me a refund or admitted they were at fault. This is very embarrassing for them as professionals and bad for me as a customer. I asked Ace to provide me a serial number for the unit the worked on, and it was in-fact the wrong unit. Still waiting for $ 175 back into my account for a bad job they did.
