"I hired TCC three weeks ago to install a heat pump mini-split systems for my 4 BR home. Their quote was competitive, their install went as planned, and the technicians were super knowledgeable and worked hard to do it right. I am thrilled with the results. I have recommended them to family already and TCC will get more business."

"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."
