Had a great experience working with GW Gill. Kent was very easy to work with, quick to respond, and gave us very fair pricing. They did some work for us here in Michigan and the whole process was smooth from start to finish. Definitely appreciate the professionalism and would recommend them to others.

Kent was very courteous and professional. He was able to diagnose and have our boiler up and running within an hour of arriving. He identified the root cause and issues we will need to address in the spring/summer. I definitely look forward to using GW Gill Plumbing and Heating again. (Previous HVAC that installed our boiler couldn't even properly diagnose the issue. See my reviews to see who to avoid).

Would recommend this company without any hesitation. They know what they are doing - and do it well. They were able to FIX my 80 year old steam heat boiler. The other companies wanted to rip it out, and sell me a new one.

When we moved to Shaker Heights, we were told that Gerry Gill and his team were the "boiler whisperers!" We have been using him (and his colleagues) for nearly 8 years and have found that to be true and then some. Their scheduling system is professional, with the latest technology to make and manage appointments and monitor service records, and their work (from annual boiler maintenance to new radiators as part of a remodel to legacy equipment leak repairs) has been attentive, responsive, and first-rate. If you have a boiler as your home heating source, based on our experience we highly recommend G W Gill.

We have used GW Gill multiple times for boiler maintenance and for big and small plumbing issues. They have been consistently honest, professional, and skilled. A rare find!

I have two systems. The system installed in the house in 1920 is steam heat with a return line. The system in the room I just added is radiant hot water in a cement slab. Gerry Gill has worked on tuning up my old steam heat boiler system. He had heat sensitive valves at the radiators repaired then he installed them. This really great improved the heat delivery and exchange in the room and prevented steam from leaving the radiator and returning to the boiler. Now he maintains my heating system. My new system is radiant heat supplied to a basement floor. This is a great system, very comfortable and Gill Plumbing and Heating installed it. Finally, I want to write that Gerry is training young folks in the trade and supervises them with patience but also with attention to details.

It’s been 20 years since Gerry installed our steam boiler, which still works flawlessly. Since such time every person to whom I have referred Gerry has been impressed with his abilities, particularly those whose systems never worked well - until they met him. A testimonial is long overdue.There is no one more knowledgeable about steam systems in northern Ohio than Gerry Gill. Before replacing our boiler, I spent months researching steam systems, interviewing others and noted that he was considered one of the experts on an informative site, HeatingHelp.com. His knowledge is unsurpassed: he demonstrated steam traps/vents, along with associated patents to me when I first met him. He and his partner published their research on steam air vents/traps, both old and new, in the form of a chart, which was sold on HeatingHelp, proceeds of which went to charity. I doubt that you find any other plumber who does research, makes his charted results available to help all and directs proceeds to charity.
