Peter Connolly is the coolest and warmest HVAC guy! We called him in to evaluate installing AC in our 1840s West Newbury house - no easy task! He was great to work with right from the start. Patient working through options, answering questions along the way and flexible in working around the other carpenter we had working on one of the walls where one on the mini splits needed to be mounted. He’s responsive, reliable, and honest - something that seems sadly rare these days. It’s not easy for us to outsource work on our home as we’ve done most of it ourselves in the past. I’d hire Peter back in a heartbeat. Thanks for everything Peter!
Peter & Steven did a nice clean job installing my new five head Mitsubishi mini split system. All in all this took 4 days to install and now I am waiting for the Massave rebate that was submitted last week. I would highly recommend 4 Seasons Heating and AC to anyone looking for this service -Peter
My wife and I recently purchased a home in West Newbury believing that we would have to replace the oil boiler or switch to an entirely different heat source (heat pumps). Peter quickly diagnosed the problem and offered a cost effective solution. Peter and his son Steven were communicative, tidy, honest, professional, and most importantly kind. Knowing that my wife was pregnant they went above and beyond to help me with tasks that were difficult to do on my own, such as moving a mattress and taking down a piece of sheetrock. We are more than happy with the work that was done and will continue to use 4 seasons for all relevant projects in the future.
4 Seasons is exceptional. They are very personable and efficient. Super respectful and polite. We love the new heating and cooling system that they installed. It’s much more efficiency and comfortable in our home. Talking with neighbors about quotes, we also found the pricing to be the best! We recently had an issue with our thermostat and he fixed it the next day. Highly recommend!
I recently had my home AC system replaced by 4 Seasons, and the experience was exceptional from beginning to end. Peter and Steven were absolutely fantastic—professional, knowledgeable, and incredibly courteous throughout the entire process. They arrived on time, explained everything clearly, and worked efficiently to get the new system installed. The quality of their workmanship really shows. My home is cooling faster and more evenly than ever, and the new unit runs so quietly. Peter and Steven also took the time to walk me through the new system’s features and made sure all my questions were answered before they left. I always prefer to buy local and support independent businesses over the big corporations!
