Our technician met with the homeowner upon arrival. First, he performed the maintenance on the heating system. Then the tech performed a diagnostic on the system to test all controls, safeties, and combustion. He installed the customer-supplied filter and spoke with the owner about the humidifier canister. The tech found issues with the inducer and provided options to address them. The customer pointed out issues with an old humidifier fitting. While performing the work he spoke with the homeowner about the age of the water heater. Performed all repairs suggested and tested and performed correctly. While collecting payment spoke with the owner about air quality and at this time owner wishes to install a new air purifier. Installed and wired and it is performing as expected.
