Peterborough Refrigeration installed a multi unit ductless heat pump for my wife and I in February of 2018. Our home was previously heated by baseboard heaters and a pellet stove. The company was great from the initial honest quote, all the way until the first annual service this week. The units have worked great, and kept the house nice and warm all winter, and cool in the summer. After initial install we did have some minor programming issues with the units (manufacturer issue, not the install) and Peterborough Refrigeration arrived the same day of our call to troubleshoot. We had received several quotes prior to choosing Peterborough Refrigeration. They were the most honest, clear, concise and professional. Would highly recommend their services for anyone in need or heating or air conditioning.
