Nat and Eurail were the service technicians that came to my home. They did an excellent job informing me of the upkeep of my older boiler furnace. They cleaned it, drained it, and applied the necessary solution to keep it running properly. They were so nice to bring me extra oil the next day. They applied oil where it was needed. They were VERY helpful and professional with my concerns and questions. I recommend Chatham cooling and heating.

Chatham Comfort came out to clean and perform maintenance on my furnace units. I just completed finishing my basement and there was a lot of dust from the drywall. The guys did a good job. The units seem to be working well. They were on time and extremely courteous. From my experience, I’d highly recommend them.
