Heating & Air Conditioning / HVAC near Manchester Center

“I recently purchased a home in Manchester, and decided to go with Cota and Cota for my heat and oil needs. Unfortunately, I had an issue with my boiler that required me to shut it off. Their technician, Ethan, responded quickly. He was very knowledgeable, kind, and professional. Despite running into a few hitches, he was able to get my heat up and running within several hours. Whenever I call their office, I am warmly greeted by their receptionist, Jen. She is always patient with my seemingly endless questions and is an absolute sweetheart. Admittedly, I generally don’t take the time to make such reviews, but have had such a positive experience that I felt obligated to do so. Their oil costs are slightly higher than some of their competition, but the quality of service makes it totally worth it. Cota and Cota truly lived up to their reputation and I will certainly recommend them to others in the future.“

“I’m sure everyone at GSK is great, but Chris is who normally services our house and he is by far the best at what he does. He is friendly, personable, prompt, efficient, does the repairs quickly, explains everything so I can fully understand, and is very knowledgeable about every system we have. Beyond that, for example, he thinks through how the unavoidable delay of waiting for a part to come in can impact us and finds a temporary solution to make it right until the final repair can be done. It would have been far easier to say “you’ll just have to wait” but instead Chris always goes above and beyond to set us up with a solution. With service like this, GSK will always be our first call.“

“I have used High-Tech for the past 5 years, first for an installation job, and more recently for repair work. They are super responsive, professional, reliable and fair. I highly recommend their services.“

“We are new customers but that didn’t stop them fixing my furnace the day I called. The tech that showed up was organized and knew what he was doing. Anybody looking for a fuel delivery company that actually does repairs should give these guys a call.“
