Lindsey Desrosiers
Edgar did the initial inspection and application. He was very friendly and pleasant. He listened to our concerns and worked with us. Bruno and his team installed our mini splits. They were very efficient and friendly as well. They even worked around our son’s nap schedule. They made sure everything was how we liked it before proceeding to something else and they gave their honest opinions.
I highly recommend going through GEM, even if they are a little pricey, their financing programs are accommodating.

This guy is amazing Furst of all he listens and secondly , he doesn’t mind a little extra work to solve a problem . With his partner Gennaro they explored every aspect before discovering
G what had not been done to my setup. And after correcting that , they did a review of Step 1 EXPLAINING OPERSTION . Each new install should start with this approach by Joshua and Gennaro.
