"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."

"Andrew knocked this install out of the park! He replaced an incredibly inefficient hot water heater with a hybrid hot water heater, ran the condensate line through pipe straps screwed into drop in anchors along our basement wall with the cleanest looking final result that surpassed every expectation I had. He was very communicative well within the budget and will be our go to for any future work we need as long as we live in this area!"

"East Coast Plumbing and Heating provided us with a great service on a big job of replacing our 30 years old furnace. Dylan was very accommodating and explained the process in a great detail. His estimate for the job was honest and fair. Dylan and his crew did the job in one day and did an excellent work for a reasonable price. We are very happy with this company and we will work with them in the future. I highly recommend East Coast Plumbing and Heating."
