"Very well installed Furnace at a very good price. Ruben has a large area over which he works, so I would recommend giving him a good amount of time upfront to get the required county permit, especially if he has to register with the county. His prices were at least 30% lower than the competition. I will get him to do my AC when it is needed."

"We called Tuscan and had someone out to our home within a few hours. Joe assisted with the install of our new system, and we are so pleased with the entire process. Joe was friendly, knowledgeable and his work was very impressive and clean. We were so happy with Tuscan, from start to finish, and would highly recommend them to our friends and family. "

"Tony did a great job replacing my broken 50 gallon self venting hot water heater. It is in a difficult space to maneuver getting the old one out and the new one in. He did a great job updating what needed to be done (in my old 1910 home so there is always something!) and I feel very confident in their work. Limelight is my go to place and am so glad I found them!"

We love seeing a new furnace installed, it means years of comfort and reliability to come!

"Every step, from the estimate with the super friendly Ryan, to the final walk-thru with the always professional Gemini, was absolutely top notch. They installed a new furnace, A/C, and tankless water heater and we are very happy with the work and final outcome. The whole crew was wonderful!"

"I highly recommend Tyler with Bison Mechanical for any furnace or HVAC needs. He provided exceptional, professional service with a same-day response that saved me over $1,000 compared to other estimates. Tyler is remarkably honest and efficient, making what is typically an intimidating process entirely seamless. He came highly recommended to me, and I will certainly be recommending him to everyone I know."
