What Heat Pump Customers Say
South Shore homeowners saving money and staying comfortable with Bay State heat pump installations.
I cannot recommend Jay and his team highly enough. The quality of their work was outstanding. Communication and professionalism was excellent.
Terrific, local, reliable, honest and expert service. Incredibly responsive and excellent communication right from the start to the end. Thorough and fully committed to ensuring customer satisfaction. Neat, tidy and completely conscientious - leaves no trace. Highly recommended!! Don't bother with the others. Just look at the reviews!
Theses guys were attentive, knowledgeable and very affordable. They came by almost immediately when my pilot light went out. They were personable, professional and super quick to get quote and schedule a replacement and install. All happened within a matter of days. Other bigger companies took days to respond and came in double the price. I’d hire bay state again in a heartbeat.
