Mini-Split Systems:
An Overview
Mini-split systems are an energy-efficient and flexible solution for heating and cooling your home.
Unlike traditional HVAC systems, they don’t require ductwork. Instead, an outdoor unit connects to one or more indoor units, allowing you to control the temperature in each room independently. This zoning capability ensures personalized comfort and energy savings.Â
With easy installation and quiet operation, ductless mini-splits in New Hampshire are a great choice for both new homes and renovations. They offer year-round comfort and improved air quality.

Lance, Jordan, Keanan, Greg and the whole team were great! From sales to finalizing the installation, I couldn’t be more pleased. The Bergeron team were interested in learning about what system would make me comfortable in my home. They answered all my questions. The installation team was professional, polite, efficient and conscientious. They took care of my home throughout the installation—on a day when the weather didn’t make it easy. Thanks guys!!

K E Bergeron has provided exceptional service from their initial assessment to installment of our [Mitsubishi Electric] heat pump systems. Tom and Monique were thorough and straightforward about the process and the cost and offered a quote at the end of their assessment. The operational team was communicative prior to installation. Jesse and his team were incredibly efficient and respectful of our home and were very clean and tidy. The team was courteous and excellent problem solvers. They installed 5 indoor units and 3 outdoor units in less than a day. At the end of installation Jesse provided us with superb guidance of how to best use our new system. We are so appreciative of the entire team and would highly recommend them for this work. Their customer and technical service exceeded our expectations. To note, we chose K E Bergeron after diligent exploration (7 total assessments) and are so, so glad we chose them to do this work in our home.

Even more positive reviews will be forthcoming. But I can say that Mr. Jesse Fish and the entire Bergeron team, including Lance LaFontaine, Nils Ahlberg, Keenan Jasmin, and several others (including the electrical contractors) were excellent to work with. Highly professional, obviously skilled in their trades and knowledgeable of these new technologies. They communicated clearly and left my residence in better shape than when they arrived. The fact that this large project was completed in one day was amazing. I highly recommend Bergeron and this team to anyone! Now, with the [Mitsubishi Electric] heat pumps running, and in very cold conditions, my house is warmer than its has been in years. Tom Harrington was great to work with as he investigated our residence, performed a thorough load calculation and specified the equipment to be installed. Thanks, team!!

"I want to thank all the people of Bergeron Mechanical that made our experience of a new Bryant HVAC system a pleasure. From meeting with Caleb for trying to fix a heating system that didn’t want to be fixed. Mike who explained everything, Eric guided us in getting a new system .Greg quickly set up installation.Then Lance,Adam,Keenan,John and Jorden worked as a team to remove the old system ( dig out the frozen pad ) and replace the new furnace and air conditioner unit in one day . Then again John and Jeremy came the next day to do the finishing touches. The whole TEAM was just so awesome and caring, they went above and beyond doing a professional job . Kim got the right guys Thank you again"
