When our AC stopped working Jack was here in less than 30 min, diagnosed the issue and checked both inside and outer units and not only fixed it with an hour but also gave us suggestions for maintenance and replacement. Great service, great response time and communication and reasonable!

I shopped around for a replacement mini split unit and every single HVAC company out there wanted a $200 estimate fee... and those that didn't, quoted me 7k or more. Not only that, there was a minimum 2 week wait for it to happen. The owner of Giuliani is a young guy, and a local to my town. His dad also owns a contracting company, so I was comforted that he grew up in the business. Jack, the owner of Giuliani HVAC, didn't ask for a fee to give me an estimate...and he was at my house the day after I called to give me a quote to my face. But get this...He was able to replace my mini split within 2 days for HALF WHAT THE OTHER GUYS QUOTED! He didn't leave a mess, was super polite and professional...and I am THRILLED to have found this guy. It has taken me about 15 years to find good contractors to work on my house. THIS GUY IS A KEEPER. Heads up, make sure you TEXT him when you want to do business. That's what worked for me best.

Jack and his team installed a new HVAC system in the first floor of our house. Their work is very neat, efficient, and works great. Communication was seamless through the whole project. I hope to refer them in the future.
