What Our Customers Have To Say


Steve Laverone

Grizzly now taking over the maintenance contracts established thru Lodi Services. The service tech, Matthew, could not have been more professional. We will miss the great service from Lodi Services but it looks like we're in good hands with Grizzly.

Jim Musgrave

Dave and his team are first class! They are very courteous and respectful, and worked diligently to overcome some installation challenges with our ductwork. Highly recommend them!

Maggie Gordon

Grizzly Mechanical Services always makes time for our problems. They are quick to identify our problem and quick to resolve it. We have had them out maybe four times in the past 3 years for different issues. We would highly recommend their services.

Jerry Stewart

First, Grizzly quoted a better system at a competitive price. The two technicians who installed the system were very knowledgeable and professional. Grizzly also installed a whole house fan that further helps to save energy and money by bringing in cool fresh air at night.

Scott Hamilton

The Grizzly crew is very professional and proficient at their jobs. They have installed two full house HVAC systems for me on schedule and within their estimated quotes. I would recommend their services to anyone.

Gaelynn Nunes

This was my first experience with this company since they purchased the old business that I had worked with for the last 12 years. Everyone is great, from the people in the office, to the maintenance technician. So happy that this has been a smooth transition!

Cierra Bertsch

If you are looking for a company to fix or replace your HVAC system, I highly recommend Grizzly Mechanical. Dave was communicative, knowledgable, and extremely patient when dealing with our home warranty company. The work that was done by Dave and his team was clean and done quickly! Thank you guys so much.

The folks at Grizzly Mechanical Service went above and beyond to getting our AC up and running at a critical time. We are so happy and grateful.

Jennifer Whiting

I wish I could give 1,000 stars! I can’t say enough how IMPRESSED I am with Grizzly. From Dave coming to do the bid, to everyone in the office and ESPECIALLY the techs that came out to do the work. They were so friendly, professional and knowledgeable. I even had to leave my house for awhile and completely trusted them all. I don’t think we’ve ever encountered such amazing customer service. A HUGE thank you to everyone. You will not be disappointed if you need their services.

Jerry Belluomini

John, the technician, has been out to our house a few times for AC issues and has been prompt and professional every time. Grizzly Mechanical is an excellent value. They are professional, responsive, the quality of work is excellent and they are always on time and if they are running late they will call with an ETA. I highly recommend them for all your AC work.


Grizzly was sure up to the challenge trying to install a central heating and air conditioning system in my old farm house. As if that wasn't enough I also had a 2 1/2 foot false celling. I wasn't sure it was even possible! They said it was and did an excellent job of it. Nothing came through the false celling except the vents. They were all very patient and knowable while answering my questions. I would recommend them to everyone.

Tep Miz

We have trusted Grizzly for all our Hvac needs. They are always ontime, efficient, and trustworthy! Their customer care is always awesome. They always work with our busy work schedule. I highly recommend them

Marianne Karver

Grizzly Mechanical Services were great to work with and very efficient. They also returned phone calls promptly and offered great advice. I would highly recommend them anytime. They also did a great job inspecting a system for me.


Owner David gave me a consultation on installing a whole house fan. While I declined getting the service done due to having a lathe-plaster ceiling which the cutout in my ceiling may hurt the structural integrity of my ceiling, I appreciated the honesty, professionalism, and options given by him. Definitely consider them for your heating and AC needs.
