J.A. Bertsch Heating and Cooling

"J.A.Bertsch HVAC team did a superb job with the installation of 18,000BTU Carrier mini-split in our home . Workmanship is tidy and routing efficient along with thorough unit commissioning & explanation of use and care. Thank you Chris & Josh! Jim"

"These guys did an excellent job. Very thorough to explain things, friendly and very efficient with time of install. We had our hot water tank, AC and furnace all done in one day. They were so kind to give us the option of an earlier appointment when someone else changed theirs. it is wonderful that they have an annual check up a year later to make sure everything‘s running right. Highly recommend this company for anything heat related."

"Top Highlights • Multiple prior diagnoses overturned by a detailed second opinion • No cracked heat exchanger despite being told the furnace was unsafe • Exhaust leak traced to one true source, not multiple issues • Over $1,000 less than competing quote • No pressure to replace equipment or upsell services ⸻ I purchased my new-construction home in 2019. In December 2020, less than two years later, my furnace developed a cracked heat exchanger and a carbon monoxide issue. The original installer, Bill’s Heating, told me labor was no longer under warranty and quoted approximately $1,600 to repair it. I was advised that replacing the furnace entirely would be a better option. After the new furnace was installed by Bill’s Heating, I had to request two follow-up visits to address an exhaust leak that caused water damage and mold in my garage ceiling. It took some persistence to have the issue addressed. In mid-December 2025, I again noticed water dripping from the exhaust system and pooling near the furnace. I contacted Herliman’s for a tune-up. Based on their assessment, I was told the furnace had a cracked heat exchanger and should be condemned. They quoted just under $2,500 for the heat exchanger, another $1,600 for exhaust repairs, and additionally told me—without testing—that my refrigerant needed replacement for another $2,500+. Concerned by the severity of these findings, I contacted JA Bertsch for a second opinion. Tim, the service manager, conducted a comprehensive inspection. He disassembled the furnace, visually inspected both the primary and secondary heat exchangers, explained the process in detail, and allowed me to inspect everything alongside him. He used a borescope only where appropriate and confirmed his findings with proper exhaust gas testing. His conclusion was clear: the heat exchanger was not cracked and the furnace was safe to operate. Although there initially appeared to be multiple exhaust leaks, Tim quickly identified a single source of the problem, preventing unnecessary repairs. His quote to fix it was over $1,000 less than the estimate provided by Herliman’s. Throughout the visit, there was no pressure to replace equipment or purchase additional services. I chose to enroll in JA Bertsch’s Comfort Club because their transparency, experience, and professionalism earned my trust. Katie in the office was also excellent—professional, responsive, and scheduled my appointment the next business day. JA Bertsch stood out by focusing on careful diagnostics, clear communication, and workmanship rather than assumptions or upselling. After my experiences with Bill’s Heating and Herliman’s, the difference was unmistakable. I highly recommend JA Bertsch to anyone looking for an honest and highly competent HVAC company."
