Spoke with the customer about how the system has been performing and she had any questions or concerns for me before getting started completed the maintenance inspection of the gas furnace, while visually inspecting all AC components, but did not run an AC mode today. Replace customer provided air filter and spoke about other services loving air provide such as water heater inspections and gas fireplace inspections.
