“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.”
