Outstanding service. Ron helped us out on Christmas Eve! A great company. Highly recommend.

Ron goes above and beyond to get you back to being warm in the winter or cool in the summer. Truly a 5 Star service that I would recommend to anyone.

Have known and used them for years. Ron is honest, and does great maintenance and repair work

Ron at Subzero Mechanical is the best!! He is very reliable and efficient. Always just a phone call away always 🥰❤️

Highly recommend Subzero Mechanical. Ron went above and beyond to assist me getting ac restored to my home. Best in the business, you will not be disappointed!

We had lost heat in our home on a cold day and Ron and his team were out the same day and got us back up and running!
Could not ask for better service and so grateful to not endure another night in the cold. Thanks so much!!

Ron, of SubZero Mechanical, is an experienced professional who is able to easily explain the issue and gives it to you straight. He never tries to up sell you or sell you on extras.

Worst company to deal with from the owner Amy to the technician that did the work. Amy is very rude, very nasty and very unprofessional. The technician should probably redo some classes, he connected the AC to the heating element instead of connecting directly to the transformer, this would have kept my AC from blowing out again 20 days later due to overheating.

We called Ron late Friday and Saturday he was back with a new unit and stayed late until we had Air condition again. Fantastic job. Highly recommend.

It's exceedingly rare to find someone as dedicated and thorough as Ron in this line of work. Can't recommend Subzero enough! I'll never use anyone else for HVAC work and you shouldn't either.

I recently hired Ron of Subzero Mechanical to install a new HVAC unit in my rental home. The work was very professional and done in a timely fashion. The price was highly competitive!

Shady company. I had a good experience at first and everything seemed great with my AC install. Afterwards, I tried contacting the owner to fix the issue of the catch pan filling with water since he tried fixing it when the AC was replaced. He continually dodged me and eventually blocked my number after a couple cordial attempts to contact him. They seem to do OK work but buyer beware if you have a problem. Another fly by night company that gets their money and runs if there is an issue.

Ron did a great job and I would recommend him without hesitation. He asked questions, listened (mine was not a typical issue), developed theories and did a thorough job inspecting and testing until he solved the issue.

Ron came out within the hour and had the issue fixed in no time. Very professional and courteous. Went above and beyond. I will definitely use him in the future!
