Best Heating & Air Conditioning / HVAC In North Billerica

“Called at 8:45am for a failed hot water heater. They arrived at 10:30 am on the same day. From the begining the the coordinator and technicians were very informative and communicated the entire process to me before starting. I would HIGHLY recommend Ostroski Plumbing to anyone that I speak with.“

“Mark and his team are always extremely responsive and have helped out every time I’ve needed them. I called early this morning and my problem was resolved by noon. He also installed a separate system in a different part of the house last year, and I am extremely happy with it“

“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 I have a very old home and the entire HVAC system was out of date and incredibly inefficient.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.“

“We are SO incredibly impressed by Jeff and his team. They installed a new EK boiler for us and provided competitive pricing, incredible customer service, and top notch technical expertise. Jeff left our basement spotless and even cleaned up/fixed things that he absolutely did not have to do to make all the plumbing look so nice and tidy. He came back to test the boiler combustion again for good measure and to show us how the unit works. Not only is he a true professional, but a really nice guy too. Highly recommend!!“

“We have been using CRS for years. Their service and workmanship is second to none! They are a bit far away, but well worth it. I trust them completely! They have kept our large walk-in cooler running for decades!!!“

“We’ve been using Medford Wellington for all of our refrigeration and plumbing repairs, and they consistently deliver excellent service. Their team is highly responsive, professional, and easy to work with. Whether it’s routine maintenance or urgent repairs, they handle the job efficiently and with great attention to detail. They’ve become our one-stop shop for nearly all of our facility repair needs, and we truly value the partnership.“

“Prompt, professional and reasonable. Sam & his team were thorough throughout the process as they replaced our entire Central Air system during the busy end of June / early July time period when most AC systems fail and their schedules are at their busiest. I cannot recommend TJ Heating & Cooling enough and will be using them for our HVAC needs moving forward. Thank you Sam & team!“
