“From estimate through invoicing, scheduling and furnace installation, the service was great - professional at every stage“

“Our AC stopped working and turns out it was just a bad capacitor. Had Jim from Kenna come out and we had AC within minutes. I will always use Kenna as they are fair, on time and overall just a pleasure to deal with“

“Russell was very professional and on time. I highly recommend working with him, and I will continue reaching out to him for all of my HVAC needs.Services: HVAC duct & vent installation“

“The technician quickly inspected the furnace and noticed the heat exchanger is cracked and needs to be replaced. I will require a new furnace/AC. Will do so for my own safety.“

“The whole experience with Herchenbach Mechanical was excellent, from estimate to installation.

Curtis, who handled the estimate, was professional and knowledgeable—he even diagnosed an issue with the original furnace installation (done by another company) that was corrected during this project. Scheduling was flexible and easy.

The installation crew arrived on time, prepared, and worked efficiently. They protected floors with pads and mats, kept the work area spotless throughout, and did a thorough cleanup at the end. Though they were installing AC, they tested the entire system and corrected a problem with the heating system settings (set when furnace was installed by a different company) that will improve performance and efficiency.

The new compressor and coil installation is neat and well-finished, with all wiring and piping properly routed. I would highly recommend Herchenbach Mechanical for any heating or cooling needs.

Tony from Herchenbach came today to address a minor issue after my AC installation yesterday.

He arrived right on time, performed thorough troubleshooting and diagnostics, and resolved the problem quickly.

Very professional, effective, and courteous. I would definitely recommend Herchenbach for any heating and cooling needs.“

“I truly was appreciative of the process. It was stress-free and the workers did the work efficiently. A really good company if you need work done. You won't regret that you called.“
