Dispatched our Corona CA area technician to a restaurant for a second opinion on the state of their air conditioner. Our technician arrived onsite, checked in with management and proceeded to the roof. After obtaining all asset information the technician surveyed the systems. All units were in poor condition, no filters as they'd been removed and left on the roof. All condenser and evaporator coils were clogged. Units #1 and #3 are in the worst condition, rusted out and multiple failures. #2 and #4 have been repaired before. #4 was off due to a broken belt. Was able to get #4 up and running with a spare belt for now. Will quote all necessary work for the customer, including the replacements.
Our Corona California area technician responded to a no cooling call. Back air conditioning unit wasn't working. Upon arrival, found that the air filter for the system was badly clogged, allowing little airflow and causing the evaporator to ice over. System was slightly low on refrigerant, will recommend a leak search, unit is working for now.
Dispatched our Riverside County technician back to a vitamin store to complete approved HVAC repairs. Our tech replaced the blower motor and pulley on the #2 Carrier unit, and repaired melted wiring. Also found the unit had 3 blown fuses and burnt out contactor, that he was able to replace from truck stock. Continued troubleshooting the unit and found that the CLO board and thermostat had also failed. Will order parts ASAP to return and resolve.
