It’s always a pleasure to work with the DiBiase team. Scheduling was easy, as usual. (Thanks, Maria!) Service was on time and on target, as were follow-up recommendations. (Thanks, Luis!)
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.

7/10/25 Tan Performed QA on new ac install from June for 2nd floor. Indoor system located in basement. Noticed a ton of condensation on ductwork but the garage door was open when I arrived. No issues with dip switch settings as the furnace was installed in 2019 and originally set for 3-ton system. Temp split was roughly 15° but it’s likely due to humidity and leaking damper on bypass humidifier. Refrigerant charge was good and didn’t indicate airflow issues. Static pressure: BF -.2, AF -.3, BC .6, AC .3 ESP is at .5, TESP is at .9 Found all wiring good and proper. Zip ties were used to keep them neat. Drain and ez trap are pitched and working properly. Same for condensate pump operating as normal. Amp draws were good. Lineset is clean and insulated. Caps were on tight. Outdoor unit and disconnect are leveled. Surge protector is built into disconnect. The blower in gas furnace has existing x13 surge protector. Service record is visible on the system. Client has no complaints about its p
