"Cannot say enough about this company the work was excellent and done in a timely fashion. Would not hesitate to recommend this company for any job. Extremely happy with the work"

"Joe, the AirCo sales representative, was very professional. He actually asked for my feedback on priorities for a new boiler. This was important to me because the boiler sits below our family room, and the noise level of the boiler was as issue. His proposals listed several boiler options, based on heating efficiency, which were competitively priced. The installation was run by Steve, who was able to fit in the installation the next week. Steve, and his crews, were punctual and courteous, and the installation went smoothly. It's only been a week, but I am very pleased with my Bosch boiler, the quality of the work, the price paid, and the timeliness of the installation."

"Diagnosis and repair were straightforward and the talented Mike, who has done other great work for us on our ACs, had a replacement pump in his truck. Swapped over in under an hour. Cost of the repair was quite high, mainly due to very high price they charged for the pump. A Taco pump that I could buy for $175 was priced on this repair at more than $500. I get that it was an urgent situation and I’m happy to pay reasonably for the response but that mark-up bothered me. I called the office, had a long talk with the owner; sadly, she offered no consideration at all. Yes, it’s hard to find and keep skilled techs, but now seems that most HVAC firms have a business model like a car dealer’s service dept, far more corporate, less flexible or customer-considerate."

"Ken's HVAC was immediately responsive to my call and came the next day. When we noticed an additional heating issue I called on Sunday and Ken picked up and scheduled to come out on Monday. He did, and we now have heat. Ken was thorough, professional, and explained everything he was doing. I felt very confident in his work."

"He explained how they would design and install the new furnace and all the zones. He obtained new hot water heater at no additional cost as well as the available rebates. The actual installation was accomplished in one and a half days. Everything was done very professionally and the area left totally clean. He"

"My central AC unit has been broken for several years. intermittently working during hot summers. I've had several HVAC companies come to diagnose and all of them told me different things: replace the whole system, new lines, etc. potentially costing tens of thousands of dollars. So I decided to troubleshoot by myself and pinpointed the issue: the filter dryer needed to be replaced. No company wanted to do this small job. I called Emerald HVAC and told them about my issue, they sent in José, who diagnosed the issue to be what I said. He replaced the filter dryer and the AC unit works perfectly now after several years! In short, Emerald HVAC will be my first choice for any HVAC work in the future. They are honest, professional, and reasonably priced. I recommend them without reservation!"

"They Do Great Work. No complaints. They where prompt and on time. They have great price."

"Kevin was quick to respond to our service request, friendly, knowledgeable and thorough in his work. I have already recommended him to a neighbor!"

"Went extremely well. Jeff told me the options and talked me through each of them. Once decision was made, he scheduled everything and was done within a week. Removed old oil burner and tank. Installed new Rinnai combi unit, so now there was more room in basement for my clutter. He went above and beyond. Did such a good job, we hired him to redo our bathroom and received the same, excellent work. We will be keeping him on our speed dial for any other work that we will be doing in the future."

"Great !! Gabriel was on time and went right to work. He took pictures of duct work before and after. He supplied my wife and I N95 masks to wear during the cleaning keeping us safe. Gabriel was a true professional."
