"The servicemen were very helpful and happy to answer all of our questions, and seemed very knowlegable. Some of our questions were technical. I called Knaak on a Sunday and much to my surprise they came out that same day. They were able to replace my furnace the nestx day for which I was grateful since I had no heat."

"Cellino did an excellent job. After calling five plumbers to fix a shower head spewing hot water and none of them could come for 4-5 days. I got hold of Cellino who came in a few hours and corrected the problem. The tech was very knowledgeable and had the job done in no time. Excellent job and of course 5 stars. Had I waited I probably would have had a lot of damage to my bathroom. "

Emerald Heating & Cooling was founded in 2000 by Marty and Carrie Sheehan, who combine their strengths to offer great HVAC service to the local area.\n\nThe business began after founder Marty Sheehan worked for an HVAC company and trained under a wise technician who told him “be like the duck on the water.” By this, he meant that ducks always appear graceful and in control above the water, while below the surface they are trying hard to stay afloat. It’s a metaphor for working hard while doing a beautiful job, hustling without mistakes, and doing great work without the fuss.\n\nMarty has taken this mindset and applied it to every aspect of our business, from the logo to the mission. This is how we approach every job we do.

"Great job, very professional."

"Friendly. Helpful. On time. Affordable. "

"Terrible, technician left and I still had a leaky sink. Said that I would have to make another appt. “Bullied” me into getting a $800.00 garbage disposal two months prior to avoid pipes clogging, two months later, same clogging !!! Technician went in my basement and told me I needed a new sump pump. Cellino is trying to get as much money from me as they can, without finishing their repair work. Never again. Horrible customer service and technicians have absolutely no idea what they are doing."
