"I've been using Shavitz for maintenance on both my HVAC systems for three years, and they've been great in every aspect. Because of my trust in their work, I'm now on a service contract. A while back, Shavitz also replaced my A/C coil in one of the furnaces that failed due to the installing company's poor installation. That repair was also perfect."

"Vinny came over to my home the same day to give an estimate as I needed to replace my exisiting humidifier. I already knew it wasnt working and super old so best to replace it. He explained everything to me when looking at my furnace room. Explained the different size and efficiency of the various models I could use with the size of my home. Quick to schedule installation as well :) I will definitely use this company for future HVAC needs!"

"It went very well. Joe did such an excellent job in his initial meeting that we decided to go forward with him and his crew to install HVAC system for our 3 flat. He showed up on time every day and finished the project ahead of schedule. He was very professional, experienced and patient. I highly recommend him and his team for all your HVAC installation/upgrades. Thanks Joe!"

"In May of 2021, CR Mechanical replaced our HVAC equipment (furnace and AC), and installed a new air scrubber and an ecobee thermostat. We were very satisfied with their work (exceeded expectations), and Craig is an excellent installer (that was most important to us). The ecobee was defective out of the box, and he reinstalled our old thermostat and was back the next day (as promised) to install a replacement ecobee. Everything works great."
