“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! ❤️“

Professional, quick and very top notch work“
