04/12/24 : techs Cody and Hunter arrived at customer's home, we were guided inside to the thermostat and indoor unit. As we were verify that the unit was running we found that the outdoor unit was not turning on. The unit gave a low pressure fault code, so we hooked up the guages and found the system had no charge. We conducted a leak search and found one at the indoor coil, we did not have the tools on hand to repair the leak. We charged the system and got the unit to turn on so the customer would have cooling this weekend and conducted as much of the tune as we could inside. A more senior tech will come out Monday to repair the leak and complete the rest of the tune up.
