    I recommend Gilman. Yesterday, Troy the service tech, was early for our appointment and waited for me to arrive. He was professional, patient with me, and very thorough. They have helped me in the past and will be who I call for future needs. I normally do not publish reviews, but want to express my particular appreciation for this business and their staff. Earl in Mechanicsville.

    We called Gilman due to the pilot light on our water heater going out, and we were unable to get it lit. (We did call 2 other companies first that we'd dealt with before - 1 said they could come today or Friday - tomorrow is Thanksgiving - and the other still hasn't called back....). Our neighbor recently had service from Gilman and was very pleased. Chris (and his trainee) arrived on time, were very friendly, and quickly figured out what the problem was and got the pilot lit. Thanksgiving will no longer be a disaster this year - our out-of-town guests will appreciate hot showers!!

    Gilman employees are first class! They arrive on time, are professional, and do outstanding quality work! They helped us with a complete kitchen upgrade:) We would highly recommend them and will use them in the future:)
    Thank you!

    Steve is an outstanding technician. Knowledgable, thorough, and very detailed in explaining what and why he did what he did. I highly recommend Gilman for your heating, cooling and plumbing needs!

  • Tiffany Royall, Dec 18, 2021

    I had a return call this morning from Gilman before I even left for work after leaving a message yesterday. They had a repair man here at the time they had set and my hot water was replaced and working, all within 2 hours! Chris was super nice and professional. Highly recommend these folks!!
