"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 The whole job took a single day and he even removed and disposed of the old outdated appliances.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."

"We can’t say enough about Matt. He was very responsive to our need. He was out the very next day and was at our home at the time he said he would be there. (That is unheard of these days). Matt was very professional and thorough. There was no surprises with job. Matt and Chris were very efficient with the installation of the hot water tank. We would readily use Ferris Plumbing and heating for any future needs."

"?I couldn't be happier with my new water heater installation. The team was professional, punctual, and incredibly efficient. They took the time to explain the new unit's features and ensured the workspace was spotless before leaving. ?It?s a relief to have hot water back with zero stress. If you need a reliable install, I highly recommend Expedition!"
