A tune-up is more than a quick look around. Here is what the visit actually covers:
▪️ Inspecting the heat exchanger, burners, and ignition system
▪️ Checking electrical connections and testing safety controls
▪️ Cleaning components that collect dust over the off-season
▪️ Measuring airflow and verifying the system performs the way it should
The goal is finding the small problem in October instead of the expensive one in January.
