"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!"

"Excellent service from my first call to Hope and then Linda who explained in complete detail what would be required to service my air conditioner and the cost. The servicemen, Branden and Jose, were very professional and went over my HVAC unit completely. The only access to the unit’s condenser coil is from the outside which needed to be cleaned/hosed down. I’m in a 3rd floor condo which requires an extension ladder to reach. Most HVAC service will not go any higher than 25 feet but the Shavitz servicemen had no problem reaching my unit which is approximately 35 feet up. Price for the service was a little higher than I expected but I fully understand after observing the work done. I will highly recommend Shavitz to others in my condo building including our building manager and also anyone who is in need of HVAC service. Great service from my initial call thru service completion."

"Highly recommend. Found this company last year on Angie's List and this is the second time using them. I was in a pinch as the A/C went out and we have a little baby. I called and they got someone out the same day. Jeff was great...knowledgeable, friendly and answered a lot of questions! Got the unit working again! These are my go-to HVAC guys!"

"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."
