I’ve used Stan Gelber & Sons for the installation of my ductless mini-split ACs as well as for a conversion from oil to gas. Both times, their service has been fantastic. I will definitely use them again in the future. I’m a very pleased customer. Thank you 🙂

We have been using Gelber for years. After maintaining the system for many years, we finally had to upgrade to a new system. They mapped out everything and we have been totally pleased with the heating and air conditioning in every room of the house. These guys are top notch.
