What Our Happy Customers Are Saying

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.


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 🙂


Respectful, Professional, knowledgeable, everything you want in a service being provided. Grade A job! Everyone at this company from install to service has been amazing. Definite recommend!
