Vinny Conigliaro

Tri County did an extensive installation of a new heating system and additional work. Keith, Nick and the crew were prompt, courteous, and knowledgeable. We highly recommend Tri County to anyone in need of heating and AC work. Fantastic company!

Tracey Scarsdale New York

Keith, Thanks for bailing us out!

Michael Mosher

Tri County Plumbing and Heating is one of the most reliable contractors I have ever dealt with. Keith is a professional, responsible and does great work. I have had several plumbing and heating emergiencies, and Keith has always been there right away to fix the problem. I recently converted my steam heating system from an oil burner to a gas burner, and Keith did a great job in the installation and balancing of the system. I wish that all contractors did as good a job as Keith and his company.

JD Thompson

We have nothing but great things to say about Tricounty Plumbing and Heating. They are always there when we need them and we can count on them to give us honest answers and smart solutions. They are extremely knowledgeable about all the latest energy efficient products and helped us pick out and install products that are already reducing our heating bills. All of the workers are extremely skilled, polite, and responsive. We highly recommend them to anyone looking for a first rate plumber.
