"The unit is very old and it's not worth fixing as it needs to be replaced. The technician was very knowledgeable and informed me of my options. I have been using Shavitz for years and they replaced my main HVAC unit a few years back. They always come through and make it happen. When other companies say no, they try and come up with solutions to help."

"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!"

"I had a great experience with their HVAC services. They repaired my electrical baseboard heater quickly and made sure everything was working perfectly before leaving. The team was professional, punctual, and very knowledgeable. They also installed our new central A/C system smoothly with no issues at all. Communication was clear throughout the process, and the pricing was fair. Highly satisfied with the quality of work and customer service. I would definitely recommend them for any heating or cooling needs."
