“The crew arrived on time and got to it right away. Watching these guys work together, they have done this before. New furnace and humidifier installed. I got a tour of the working parts. Everything was cleaned up and removed. Paperwork done and I’m very glad we selected this company. They will be back next November for the free inspection that was included.
Thanks guys!!“

“Steve and crew do a great job. Have used them twice now. Timely and efficient. Great work all around. Provided a great solution for ventilation for a range exhaust today. Saved a lot of kitchen cabinet space!“

“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! ❤️“

“Today we had some plumbing in our kitchen, bathroom and laundry room. The bathroom and kitchen were planned, the new faucet in the laundry room was an add-on. The appointment was confirmed the day prior via text, a text with a picture of the technician was sent when he was on the way and another when he arrived! The technician was prompt, courteous, neat and knowledgeable. He was excellent. We are so happy to have gotten the recommendation, as we hadn’t used Rozga before. We will definitely be repeat customers! Very satisfied!“
