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!

We called Gross simply because they had a sticker on our furnace when moving in. Happy we did - punctual, professional, and reasonably priced. We’ve had them perform all service and install a new humidifier, all have gone perfectly. They let you know when equipment is wearing out, but by no means pressure you into replacing still functional items. Great company to work with.

After the horrible flooding in our area, we were in urgent need of a new furnace—and Gross Heating and Cooling truly delivered. Jerry, the co-owner and technician, personally came out and installed a Carrier Infinity furnace the same day. His expertise, professionalism, and genuine care made a stressful situation so much easier. Behind the scenes, his wife Cari was instrumental in scheduling everything. She was incredibly kind, responsive, and efficient—making sure the process moved quickly and smoothly. It was clear that this is a team that truly cares about their customers. Jerry took the time to explain the features of the system, ensured everything was running perfectly, and treated our home with respect. Despite the chaos from the flooding, he left the space spotless and made sure we felt confident with the new setup. The Carrier Infinity has already made a noticeable difference in comfort and efficiency. But what really stood out was the dedication and compassion from both Jerry and Cari. They went above and beyond, and we're incredibly grateful! If you're looking for top-tier service with a personal touch, we highly recommend Gross Heating and Cooling. This is a business that treats you like family! ❤️
