Reviews
Customers trust High Performance Mechanical
- ★★★★★
Great company, they installed my new HVAC system. My system was over 20 years old and needed to be repaired almost every year! After spending over 4000$ in repairs over the past few years with other contractors, High performance came out and and gave me their honest opinion on what the best solution was for our needs. At first I thought a new system would cost an arm and a leg, but they were able to get me financing and even some tax rebates. The new system they installed was also much more efficient than my old one, it has cut my power bill by at least 30%! I recommend them for anyone looking to upgrade their HVAC system or repair their current system

Dre SantosCustomer review - ★★★★★
From the first phone call to the finished job, everything was smooth. The crew was respectful, worked quickly, and left everything clean when they were done. My AC is finally keeping up with this heat, and I couldn’t be happier.
