Luis 3-27-26 land lord Calle in for issue with heater, upon arrival talked to tenant, tenant stated heater sometimes does work, but today’s concern was blower never stops. I checked system operation, I inspected heater components, thermostat and filter, filter was very dirty. Tenant has spare filter, filter needs to be change every 30 days. Found thermostat satisfied and fan to on. I tested heater and blows hot air. I switch fan to auto and Educated that if they don’t want fan to run constantly they need to keep it on automatic, during today’s visit I noticed some items that need attention, some of the ignition components are in bad shape this will be an issue soon. I provided estimate for repairs. Indoor coil is fully covered with biological growth, I would recommend adding uv light to control bacteria growth. Overall shape is poor, unit is from 2009. 17 years old. I would recommend getting an estimate to replace system. Called land lord and left voicemail.
