If you aren't a plumber/ HVAC professional, but have to pretend to be one from time to time in your business, you need Blizzard. If you are working with a Mechanical company who leaves you with more questions than you had prior to their arrival, you need Blizzard. Blizzard installed our entire HVAC system and plumbing for a new commercial build-out in 2026. (this was a complex build with a sensitive timeline) This was our 3rd build-out, so we knew what to expect. For the last decade, we have used the "big name" in CT for our mechanical needs (they start with an E) This was the level of experience we were expecting with this new build out. After our experience with Blizzard, we learned that we should have expected a higher level of knowledge, care and professionalism from the previous company we had worked with. Our build out was done so well, we have since converted our service contracts in our other locations. Their honest guidance was unmatched. As a business owner who was overwhelmed with this complex build out, Blizzard took their time to explain our options after really understanding our needs. They matched us with a system that has outperformed our expectations during the extreme heat of this past summer. They have remained a partner in our plumbing and HVAC needs. As a business owner, this level of care allows us to focus on our work. This, for any business owner/manager is truly the test of an incredible partnership. If you want it done right the first time, or no longer have a desire to pretend to know what you are doing with your plumbing/HVAC because you cant get anyone on the phone or in the business- Blizzard is it. Big shout out to Dan for his eagerness to finding the right solution. His brilliance was unmatched. Thank you to Adam and Brandon and the Blizzard team for their hard work and commitment to getting our project done on time.

We contacted Blizzard Mechanical to install propane unit heaters in two of our buildings used for commercial truck repair. The Blizzard team was very professional and was able to do the install without interfering with our operations. The installation was professional, and they’re final bill reflected their quote. I highly recommend Blizzard
