    Fixed shower pressure and temperature. They were early and came in solved the problem and were very friendly and super efficient!

  • Wayne Settle, Nov 23, 2022

    Kristian and Noah searched for a plumbing problem that was affecting the water supply to my freezer ice maker. After a thorough search and inspection of the water line, they determined the cause to be with filter installed in the refrigerator. They were quick and very professional. I whole heartedly recommend the team at Gilman’s Heating/Air/Plumbing.

    Chris has been here a few times for plumbing projects, and always does a great job. Gilman does a great job for our plumbing and hvac work, and we know we can trust them with our home.

  • D S, Nov 18, 2022

    Chris and Preston came to do lots of plumbing work. Install kitchen faucet and garbage disposal, replace sink pipes and replace shower pipe -- all of which turned out to be more difficult than expected. All jobs were completed and I am happy with the work. You couldn't ask for two more pleasant and professional guys. Will definitely use Gilman and their employees again.
