“Excellent service, good, knowledgeable mechanics, prompt service, kept to their schedule service date. They did a three zone mini split system for me and did an excellent install. Worked quick, clean and professional. I would highly recommend Coastal Mechanical.
Last year I had Coastal completely install a new boiler and water heater tank. They did an excellent job, very clean work and very professional.
Recently t
hey also came out promptly to change out a rusted propane gas line coming into my home which was ready to start leaking at any moment. They sent out an excellent technician to change out the line. I couldn’t be more pleased with their customer service and professionalism. They are my go to service company.“

“We bought our Kohler whole house home generator through Winslow 6 or 7 years ago and have been extremely pleased with it. Winslow did a great job on the installation and it has been 100% reliable and always works when we need it. We just had our annual service and maintenance for 2024 done on it by Winslow and, as always, they made it easy to make an appointment and their service tech was on time, professional and did a great job--couldn't be happier.“

“What an amazing experience using Monomoy Mechanical! They were super responsive, the technician was insightful, and the price was fair. I will be using them going forward!“

Strongly recommend this company.“
