    This was our first time having Gross come out to inspect our central air system. Our technician Doug P was kind, knowledgeable, respectful, honest, and thorough. He informed me of some potential issues with my system down the line and replaced what was needed. He even gave me tips on how to keep our system running optimally. He didn’t try to upsell me on anything and left our system in much better shape than before he arrived. I’ll definitely be using your company again. Thanks!

    My 1970s A/C unit finally gave out after 50 years of faithful service! Gross had come out twice and serviced the unit to keep her running over the last decade, but I knew all good things must come to an end eventually. I purchased a 2 ton Carrier unit and Daniel, an awesome HVAC guy, was able to install it that same week! He even had to deal with a crazy dog and handled it all like a pro. He paid attention to the small details and taught me how to hose the unit down to clean it. (I was never quite sure how to do this the correct way.) I can't thank Gross and Daniel enough!
