Great service and installation
Karel Malovany - Old Lyme, CT 06371
A beautiful installation with a new pipe to the tank. The pipe that was replaced was crimped which resulted in reduced gas flow to the cooktop.
Great job! Very friendly.

George - Old Lyme, CT 06371
They show up on time or earlier ready to work. They explained the process and asked if we had any questions. Their work was neat and they cleaned up after them. So friendly and worked great together. Our dog fell in love with them and they were so nice to the dog. I do not have enough good things to say about the whole crew.
Excellent service prior to my purchase of the furnace and through out installation
