I was thoroughly impressed with the superb HVAC maintenance service I received from David Santiago and trainee, Kevin today! Before David and Kevin arrived I was very disappointed with having had my original service date rescheduled to what I thought were spurious reasons? In fact David and Kevin arrived after the designated rescheduled date and time today. GEM's communication was excellent throughout and their people seemed genuine and concerned. When David and Kevin arrived it turned the whole situation around. They could not have been more professional and knowledgable! I am now firmly committed to GEM and their Home Comfort maintenance program.

We just had our heating system replaced. We went from forced hot water system to a central heating and air conditioning system done by GEM plumbing and heating company We had Omar and Michael work in our home for 5 days they installed all the ductwork, the furnace and the condenser. These guys were very professional, kind, clean and informative throughout the whole install every day they explaind what they did and what is the expectation for the next day. Today was the last day they walked me through the whole system, how to change the filter how to operate the new thermostat and what to look for when things are not working properly. I say thank you to the whole team from planing to done, all went great to expectations
