Customers say: True professional

"I had Rob install a tankless hot water heater, whole house water filter, and run a new gas line for my gas stove conversion. He was very professional and and was quick to set an appointment. The whole job took a single day and he even removed and disposed of the old outdated appliances. Quality work at reasonable prices! Would highly recommend."

"Totally excellent service. My furnace was not working so I had no hot water. I called after 7 pm and Mike was there first thing in the morning to check it out. He located the problem and took immediate action to resolve it. Called suppliers, located the part for a 57 year old furnace. The following day Jason and Chase came and made the repair. Cost effective price with professional workmanship. Reliable and trustworthy."

"I finally got to build my dream garage to store all my tools and have a cool hangout on Friday nights with the boys n a couple coors. Chris came and did everything from the bathroom and the heating system. I will definitely be calling him back to add a mini split in the future. He was professional, punctual and clean. Very knowledgeable you can tell he cares about his clients."

"Justin at County Line Plumbing and heating came out shortly after I called the office. Due to my leaking 50 gallon water heater started leaking! He added the situation and installed a new Rinnai on demand water heater later that day!!! Not only was the price fair, but he explained everything every step of the way! Highly recommend 10 out of 10"

"Work with Tylor. His quality and customer responsiveness is top notch. I had him install 3 mini splits in our home. I originally wanted Mr Cool.. He coached me into upgrading to Mitsubishi for our area due to it’s significant quality increases vs Mr Cool and he was able to purchase and install faster and significantly cheaper than the “Home Depot” “Mr Cool” 3rd party install pricing company Highly recommend Tylor and his work"
