Swapped smart thermostats for analog on a Lennox install, got roasted by the homeowner
Did a job last Tuesday in Boise where the guy insisted on a Nest, but his house wiring was a mess from a 1978 add-on. I told him the smart unit would just cycle on fault codes and recommended a basic $40 Honeywell. He pushed back hard, said I was stuck in the past, so I wired the Nest anyway. Third call back later that week, same error, and I swapped it out with the analog unit under his grudging approval. It's been 6 days, zero issues. Maybe I'm wrong, but I think smart features just complicate things when the ductwork and wiring are pre-1980. Anyone else refuse to install them in older houses, or am I the only one?
