    We were looking for a new HVAC company after several poor customer service experiences with our previous one. The reviews for HVAC Trust seemed quite good and their price on a new Lennox A/C unit to replace our existing one was very competitive. Giselle was great to deal with in setting things up and the service techs that did the installation were probably the most professional and polite I have ever experienced in 35 years of home ownership. We are very satisfied with our purchase and would highly recommend HVAC Trust.

    Install or renovate bathroom-
    Arash and his team did an incredible job! I'm beyond happy with the work they did and the level of service overall. Summit Contractors installed a new shower for me, laid down electrical line and installed a new dishwasher, fixed two sinks, the bathtub, and my electrical panel. Arash even fixed a broken kitchen drawer that was such a small job another contractor refused to do it. Arash is so honest and really cares about doing high quality work. I was apprehensive about finding a contractor because I had previously hired who ran away with my deposit. But Arash is so trustworthy and completed the job in a timely manner. I felt that his prices were reasonable as well. I can't recommend him and his team enough!

    I am satisfied with all aspects of my experience buying and installing a new furnace with Pro Climate. Armando spent a long time at the house figuring out the best, least disruptive way to install the furnace in our finished basement. The pricing was very competitive compared with other quotes that I received. And the actual installation was done in exactly the way that Armando said it would be done. The guys got it done in a reasonable time and left no mess. Great work. I would highly recommend Pro Climate to other people.
