Thermo Cool Mechanical

The technician found that we had no refrigerant due to a leak in the evaporation coils. He filled the unit with refrigerant and detected the leak. He also cleaned the condenser coils with nitrogen. We will have to replace the evaporation coils due to the leak but we have AC for a month or two.
The technician was professional. He explained what he was doing and how he determined our problem. He spent two and a half hours here, making sure everything was working (for now) before leaving.
