“I recently had a 43-year-old furnace replaced with a ductless minisplit system in my condo. I have a very old home and the entire HVAC system was out of date and incredibly inefficient. Bryan, Jimmy, Nate and their crew were able to install the minisplits and new condenser within a week. Their prices were competitive, everyone was incredibly professional, kind and reliable.They helped me navigate the confusing MassSave process, and even brought me space heaters when my furnace was not usable. My home has never been more comfortable. The house was spotless when they were finished, I even gained a new utility closet with the removal of the furnace. Tremendously grateful for Affordable Heat and Air, and cannot recommend highly enough.“

“RER for HVAC - Great Service! For more than a decade Bob F & Jeff R have provided service above my expectations. Examples: --- Furnace failed at peak of a blizzard. It was evening, roads unplowed, horrible conditions, yet Bob F soon arrived and gave us heat. --- Jeff R solved a years-old electrical fault probably caused by original installer. No more smoke puffs / alarms in the basement! --- Today in July, Jeff restored our Central AC cooling within 2 hours of my call. . I know a company can't guarantee this level of service, but RER has been providing it!“
