Spencer, MA Furnace Repair

Excellent service in every respect: starting with the salesperson, Peter Dallas; Sean, the installation coordinator; and, of course, the installers Joe & Cristar!!
Pete was extremely professional, friendly, understanding and very flexible when negotiating the final price.
After 28 years of using a Lennox central heating and air conditioning system, we decided was time to get new systems and we went with Carrier this time, a highly respected brand too backed by GEM Plumbing as a certified provider. Both the sales process and the speed of the installation were incredibly efficient. We spoke with Peter on a Tuesday morning , and by 3:00 p.m. on Friday of same week the installation was complete. We were lucky enough to have Joe Medeiros and Cristar Fig from GEM as our technicians!
Let me tell you, this duo is exceptional! They are very young but possess extensive knowledge and a fantastic attitude. I was truly impressed by their technical work and their courtesy. These two technicians are a great asset to GEM and WE would love them to be recognized! We are very happy at home; the air conditioning system works wonderfully! And We can’t wait to use this coming winter our new furnace too!
Thanks to Peter, Sean, Joe, and Cristar for their amazing job!!
Sincerely
Mary

ALecs Reyes was the best!!! Extremely knowledgeable and professional. He turned our terrible experience with our last contractor into a positive outcome . I will add that he was a fantastic mentor to the helper he brought along today. ALecs is the kind of employee every business owner searches for….Good luck in your career at Gem Alec’s!!!

Nicole was great. Super nice, super helpful and quick. I wish I was as effusive about the exorbitant prices that GEM charges.
