"Super quick and responsive when scheduling the service. Although he didnâ t know about it before hand, he was actually able to move the whole spigot to the other side of the house and barely charged me more. Will definitely have him back in the future when more projects arise."

"Ben has put in a tankless hot water heater for our home, as well as install new gas logs in both fireplaces. He recognized we needed to re-route our gas lines and did so for us. We also sent him to my in laws and he installed new gas logs there as well. Benâ s work is exceptional and immaculate. He pays attention to details and always communicates what he is doing or needs to do. If you are in the market for any gas related work, Mayo Gas Systems should be your first call."

"Thomas arrived on time and worked efficiently. He was very nice and polite. He installed the new water heater and noticed something seemed wrong once the pilot light was not working correctly. He called the company and discovered that it had a defective part. Thomas removed it, returned it, and came right back with a new water heater which worked well. It must have been frustrating for him, although he was very professional. I can’t express strongly enough that I would definitely have him do future repairs if needed!!"
