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.

I had an issue with AC on a hot summer night. I made over 20 calls throughout the night and no response. Just one and that’s these guys here.

Our HVAC unexpectedly shut off and after seeing lots of good reviews I cold called Jack. He picked up right away and made it over the same day. Despite some major issues, they were able to get the air conditioning working to at least give us a temporary fix until we can have the unit replaced. They were polite, professional, and worked quick. Highly recommend.

Easiest HVAC company to deal with. Jack saved the day for my house. It’s been 90 degrees recently and my ac took a turn for the worst… luckily Jack showed up and was able to solve my problem. Even had the part in stock! Couple hours later my house was so cold I could hang meat. Best HVAC company I’ve dealt with and I’ll only be using Jack from now on. He’s the guy for the job!
