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 The whole job took a single day and he even removed and disposed of the old outdated appliances.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

"Wonderful service from Adam! My water heater was struggling to keep up with my wife?s long showers - which by the way she heats them up hot as hell! ? Besides the point, Adam recommended sizing up the water heater in order to keep up with the demands of some crazy hot water. Incredibly fast installation process and Adam was really friendly. I would definitely recommend him to all my friends who are looking for a plumber. You should certainly give him a call!"

"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."

"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."

"Justin was professional and knew exactly what I needed to fix my existing water heater without trying to upsell me on a much more expensive tankless water heater. He had the relief valve and expansion tank in his truck and was able to install everything without issue. I would recommend hiring them for your plumbing needs!"

"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."

"?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!"
