HVAC Repair Fresno CA | Call Mariner Cooler Center

We specialize in servicing and stocking parts for Mastercool and Aerocool evaporative coolers. Our Fresno shop carries a variety of cooler pads, pumps, and other components specific to these brands, allowing us to handle most repairs and maintenance needs promptly.

While we specialize in evaporative coolers, we can provide consulting on how a well-maintained swamp cooler can effectively complement or reduce strain on an aging central AC system, especially during Fresno's drier months. Proper cooler maintenance can help manage overall cooling costs and system longevity.

For Fresno's climate, we recommend scheduling your swamp cooler's seasonal start-up service in early spring, before temperatures peak. Our seasonal operation from March to August is designed to ensure your system is clean, calibrated, and efficient for the hot, dry summer ahead.
