What Our Clients Are Saying

Helping Businesses Achieve Success

“Gem never disappoints. From installing air conditioning mini splits, a self initiating generator, and servicing all our plumbing needs, most recently new pipes and valves to our sixty year old water system, the team have never disappointed. They have always been prompt, friendly and completely professional. They set the price in advance and it has never varied. And the work uniformly has been excellent. In short, great guys and an excellent finished product.”

— Robert P.

“When it comes to HVAC systems, one needs to trust and value one’s chosen source. GEM is a thorough, professional and customer based organization that truly reflects the saying, “You get what you’ve paid for”, using only top of the line resources, with professionals who are supportive and caring. Many thanks for a totally new HVAC system backed up by a comprehensive maintenance contract.”

— Diane H.
