Pembroke, MA Full HVAC System Replacement
In Pembroke, we helped a homeowner upgrade their comfort by replacing two original HVAC systems and furnaces in a nearly 30-year-old home. The project was completed in just 2.5 days. Here’s what the homeowner had to say:
“The team at Harborside is amazing! They came out the next day after we contacted them. We ended up needing two HVAC systems and furnaces replaced (They were the original units on an almost 30 year old house). They completed the service in 2.5 days. Before each visit, we got a text telling us who was coming and an estimated arrival time. They kept us updated throughout the day at the end of each day. They were very thorough in explaining the situation to us and left our house cleaner than they found it. We will have them come for regular maintenance in the future, and they were easily able to book the next visit while at the house. The payment process was also super easy, and pricing was very reasonable. They are professional, friendly, efficient, and prompt. Hire Harborside for all your heating and cooling needs!!!”

Marshfield, MA R-22 System Replacement
In Marshfield, we replaced an aging air handler and condenser that were still running on outdated R-22 refrigerant. R-22 has been phased out due to its harmful environmental impactspecifically its contribution to ozone depletion and high global warming potential.
We upgraded the system to use R-32, a more efficient and environmentally friendly refrigerant. R-32 offers better heat transfer, requires less volume, and has a significantly lower global warming potentialmaking it a smarter, greener choice for modern HVAC systems.
