Report
I build a shopping center where my General selected Marina as the sub for the HVAC. Marina sold me over 16 brand new 7units and install them all. One did not work and when I asked for repairer they did not repair it even though it was a new unit which was never used. I had to buy a new unit. Stay away from these guys. never, never never work with them.
