Dispatched our Lemoore California commercial HVAC tech to a cash loan store for a no-cool call. Upon arrival, our technician troubleshooted the Carrier unit and found the system low on refrigerant. Leak tested and found multiple refrigerant leaks throughout the evaporator coil. This is a very old unit, at least 25 years, and we do not recommend repairs at this time. Will quote unit replacement due to overall condition and age.
