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!!“

“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!“

“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! ❤️“

“Brian is extremely knowledgeable, as well as honest - he was real with us and did not try to upsell! I appreciated this a lot, especially considering that some other businesses that quoted us were much more sales-y. He also went above and beyond by successfully helping us troubleshoot an old furnace issue over the phone on another occasion. I would definitely go with this company in the future!“

“Mr. Demos is a very polite, respectful, and over all an amazing person! He came to my home for an HVAC inspection to find out what is wrong with my heater.

He explained it all to us, was quick and thorough, and the cost was very reasonable. I would highly recommend Gregg Heating for prompt efficient and informational. We will definitely for any further HVAC needs-- Good Job Gregg Heating!!“

“We decided we needed a new hot water heater. Our current heater still worked but was over 15 years old and we knew it was time for a replacement. We have worked with The Thielmann Group for nearly thirty years for all of our heating and cooling needs so we naturally asked them for estimates on a hot water unit. We were thrilled with the selection they offered as well as the pricing. Kevin C and his associate came out today and did an excellent job installing the new heater. They were right on time, efficient, courteous and knowledgeable. We couldn’t be happier with the job they did and feel good knowing we won’t have any issues in the future with water problems. We recommend Thielmann for all heating cooling and hot water heater services.“

“Cole was incredibly easy to work with throughout my roof inspection and insurance process. He was knowledgeable, communicative, and truly went above and beyond to ensure we received the best outcome possible.

What I didn’t expect was how a quick conversation about my school would turn into an unbelievable partnership between Vessel and Karcher Middle School. Without hesitation, Eric, Cole, JJ, and Aiden stepped in and dedicated countless hours and materials to help our students learn how to use tools and build their dream dog houses.

Their time, patience, and willingness to teach made a tremendous impact on everyone involved. The experience they gave our students is something they will carry with them for years.

I couldn’t have asked for a better or more generous business to work with. Their support has been truly appreciated.“
