How We Repair Your MasterCool Evaporative Cooler/Swamp Cooler
Air conditioners, mini-splits, window units, evaporative coolers and chillers move heat out using compressors or water evaporation, fans and controls.
Every MasterCool model has its own parts list, so we start with the model and serial number on the rating label. That tells us the correct parts and any known issues or service bulletins for your unit.
