“It has always been good to deal with Kappler, and this visit was not different! Our service technician was Liam. He texted us before our appointment that he was on his way and arrived on-time. He listened carefully to my description of the problem(s), and I walked him to both the indoor and outdoor systems discussing possibilities and left him to begin his inspection(s). In a matter of ~20 min he had identified the likely issue – which involved the replacement of the Furnace Logic Board back in 2017 by another “well know” HVAC local company. They had wired two wires in reverse on the logic board leading to the thermostat. While still allowing the AC to run ,it was causing the AC system to run only in Stage 2 and shut off. Correcting the error on the logic board seemed to fix the AC problem so far, and we look forward to lower utility bills! I will also add that Liam was very likeable individual, and was knowledgeable in answering all my questions. I really felt like I was a part of the process and not just the customer! This is why we keep coming back to Kappler for our HVAC needs. Thanks!”
