Get matched with top heating and air conditioning pros in Groton, MA

"I have been using Druziako HVAC since I bought my house in 1997. They are excellent to work with consistently provide the highest level of service. I would highly recommend them to anyone in need of HVAC services."

"Guy was hands down the best HVAC person we have ever had help us in Boston. Totally transparent, professional, easy to work with. If you need help, I would recommend asking for Guy to come out if possible."

"Joyce installed the system with new duct work, zoning, dampers, new furnace, A/C, and thermostats. They knew exactly what they were doing, installing the system as described and on time. During the 4 days of installation, management dropped by to make sure it was going well. They had all the right equipment and everything went as planned. No snags. These guys are real pros. I'd recommend them to anyone. I love my new Lennox HVAC system. My home finally is finally comfortable. The new system is also whisper quiet."

"Joe explained various options (models, efficiency rating, attic vs. cellar installation, etc.) thoroughly, promptly followed through on my follow-up questions, and prepared a detailed & accurate quote. He measured the size of the house and cold-air returns to ensure the system was sized properly. He is a patient guy & very pleasant to work with. Scheduling the installation was painless, the installers (Steve and his assistant Derek) started on time, and worked diligently & efficiently.
Everyone is very experienced and knowledgeable, and all clearly take pride in their work. They kept in excellent communication with me throughout the installation. They were respectful of my home, my concerns, my pets, etc.
They stand by what they sell, too. This winter, about 18 months after it was installed, my tankless hot water heater had a factory defect that caused it to shut off. Steve came the day I reported the problem, was on the phone with the manufacturer for hours to diagnose the issue, and came back twice more to finish the repair (3 visits might sound absurd, but it wasn't Airco's problem, it was the manufacturer's, as they were misdiagnosing the issue). The unit is now working perfectly thanks to Steve's persistence. A bonus: Airco charged me for only a small portion of Steve's time from his initial visit. They ate the cost of his additional visits! These guys are golden.

"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!"

"Kilpatrick HVAC is my go to company for all things HVAC. They have replaced a few furnaces and air conditioners for me over the years. Mike and John are very good at what they do. They are a lean team which makes them very competitive compared to big HVAC companies without sacrificing on quality. I highly recommend Kilpatrick HVAC for your HVAC needs."

"Very clean, professional and efficient. Explained the whole process and what steps to be taken to preform P.M. s on our HVAC system. We will have him back in six months for follow up maintenance."

"Duct Kings came out quickly and spent one day thoroughly cleaning the vents and scheduled the aero-seal for another day. During the process they noticed an issue with their software and rather than ignoring it and continuing the work, they stopped and rescheduled to come back and finish when the equipment was working properly. They were thorough, respectful of my home (and my pets), and wonderful to work with. I highly recommend Duct Kings!!"
