"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!"
