“I have worked with Ambrose Mechanical Services for nearly 20 years- as a commercial construction general contractor and also as a residential customer. Dan Ambrose and his team are the most knowledgeable, conscientious, honest and just overall great people to work with. The job is always done right the 1st time and they provide the most efficient and cost effective solutions to any task. We highly recommend them for any heating or cooling job (new installations, service, maintenance) and we are so grateful to know them.”

“I had Dan Ambrose install a furnace and perform some service for me. I was very pleased with the quality of his work and even more importantly his honesty. As an Engineer myself I am very particular in the quality of work being performed and the integrity of the person performing that work. My observation was that Dan Ambrose and his team are skilled in their trade, understand the technology they’re dealing with, and, most importantly, are gentlemen with old-fashioned values. Finally, the cost of their work was very reasonable and I now only look to Dan for all my heating and cooling needs.”

Jim Papa

“Dan runs a good company, with a deep understanding of multiple types of heating and cooling systems and the background and intellect to apply them in the best manner possible. Additionally, he seeks out new technologies when applicable. He is also involved in training new HVAC workers, both within and outside his own company, thus ensuring a high level of competence in the next generation of workers.

I have found Dan and his company a be great compliment to what my company does and an expert resource on all things HVAC.”

“Mr. Ambrose followed up promptly, visited our home and provided an assessment and quotation. He took the time to sit down with my wife and me and explain the System 2000 and how it would work in our house, as well as how it compared to other alternatives. We decided to proceed; Ambrose Mechanical installed our System 2000 the first week in February. There was initially a problem – the pump was defective and not sending the water through our baseboard heaters adequately – but Mr. Ambrose came back immediately (on a Friday evening, working until midnight!), diagnosed the problem and fixed it. Since then, the system has run perfectly.
Not enough time has passed to evaluate how much we are saving, but we have received one immediate benefit: more than enough hot water! In the winter, when the incoming water is very cold, our prior hot water heater could support at most two showers in the morning before needing 30-40 minutes to regenerate. That was a real challenge for a household with four daughters! But now we can all take our morning showers without concern: there is just as much hot water for the last person as for the first.

We are very pleased with the System 2000 and with the service we have received from Ambrose Mechanical.”

Randall Grossman

“We were without heat on Jan 27. I called at 7am, and my call was returned at 7:15. Tony arrived at 9:10, and within 10 minutes he found the problem. He had the heat restored temporarily while getting the new part for the permanent fix. GREAT DIAGNOSTIC AND REPAIR TO OUR FURNACE!”

Gerry Andrychuk

“In my opinion, Dan is one of the best HVAC contractors in Monroe county. His knowledge of the field and his integrity are outstanding. I will not hesitate to hire him again.”

“Ambrose Mechanical is an exceptional company. Their employees are always courteous, personable, and on time. I’ve worked with Ambrose on both residential and commercial projects and their knowledge is second to none.”

Anthony Tomasino

“I met these folks when they were installing a whole house A/C system in my daughter’s 1950s built home. Their workmanship, knowledge, professionalism, and eagerness to satisfy is impressive. And they’re just plain nice.
I’ve since had them in my home to fix a wonky Nest thermostat, and just signed a maintenance agreement. When it comes time to upgrade my HVAC systems, I won’t look further than Ambrose.”

Todd Shillington

“Ambrose Mechanical provides all my residential HVAC needs in our 85-year old home in Irondequoit. The flash boiler/radiant heating system keeps our home warm and cozy all winter, and the central AC system keeps the home fresh and pleasant in the summer. Dan, his son Matt, and his senior technician Tony are all technically competent, efficient, and courteous. As a chemical engineer, I can recognize technical talent when I see it. I highly recommend Ambrose Mechanical.”
