"This guy is a real pro! The original installer came out and gave up on the problem, and I never heard from them again. Duke came out, and diagnosed the issue in an hour. He even submitted the request for a part under warranty, received it, and came back to install it 2 days later. The cost was very reasonable. Thanks Duke!"

"My wife and I bought a house a couple years ago, and became owners of a radiant heating systems installed more than 20 years ago. Tony and Damian did a great job of understanding how my radiant heating system works, what repairs were needed/what was failing, and where upgrades were needed. They replaced the pump, both expansion tanks, and the neutralizer. Additionally, they noticed the hot water tank was installed incorrectly, and the hot and cold water connections were flipped. It's amazing the system worked, and it's nice to have a system that's correctly installed (even if it's 20 years later!). Additionally, they secured the expansion tanks to the wall (now required by code), replaced the deteriorating copper pipes connected to the neutralizer with plastic (I'm sure this is code now as well), and re-routed the overflow pipes to the outside (rather than the floor!). You can't go wrong with these guys, well done, they're true craftsmen to the trade."

"On the weekend I called a few AC places recommended by Angie's List and HomeAdvisor, BAZ Service was the ONLY picked up the phone and made a suggestion to meet to repair the AC in an hour. Edmon and his assistance came and refilled the r22 Freon when it was emptied within 30 minutes. I checked the thermostat before, while and after Freon refilling, the temperature has dropped and the AC is cool again! Within an hour and serving on the phone and in person, I would strongly recommend BAZ Service per your AC repair needs. Thank you very much BAZ Service and Edmon, the AC is working and cooling the entire house again! :)"
