"I am very happy with Ryan Laverty Plumbing Heating & Cooling. I would highly recommend them and think their prices are good with quality work too. They installed a new water heater, furnace and AC all in a single day. I'm proud to show the pictures of their work and happy to talk about them too. They show when they say. I spoke to Ryan by phone about estimate before he wrote up/emailed to me for approval. It matched his verbal estimate. They delivered and installed on time just like they said with no surprises. It all looks good and everything works great! Since it's still summer, they said they will return to fire up heat/verify no issues before that season starts (good customer service). Their team is very professional and it shows in their work. I first saw Richard and Joe during estimate as they came from a different job where seeing me for estimate was after that job. When at my house, they measured everything/noted so that proper sizes were obtained for when Ryan quoted me. I resaw Richard and Joe along with Austin and James during day of install. Everyone is very efficient. It's a tight utility room, they pulled the washer/dryer out to get everything in. They even replaced the old gas shutoff behind he dryer as it's butterfly type that leaks at no extra cost to me. The Flue from the waster heater was all replaced to be proper size as original was undersized. I was shown everything, given manuals needed, etc."
