Dial Manufacturing Evaporative Cooler Parts in Phoenix

It could be the pump, the float, the pump switch or the wiring between them, and from a web page there is no way to tell. A pump running dry because a float stuck looks the same from the ground as a pump that has died. A technician tests each in sequence and quotes flat-rate before replacing anything.

We do not publish instructions for roof work, and most Phoenix coolers live on roofs. If your cooler is ground- or window-mounted, the manufacturer's manual covers pad and pump replacement. If it is on the roof, leave the climb to someone with fall protection and let us handle the parts.

We will not give you a number, because the honest answer depends on how hard your water is, whether the cooler has a working bleed-off, and whether the pads are changed before they crust. Scale kills pumps; managing scale extends them. A seasonal maintenance visit is the cheapest insurance.

Usually none, at first. The smell is stale reservoir water and mineral-crusted media, and the fix is draining, cleaning and fresh pads. If it returns quickly, the pads or the pump may be due, and a technician can tell you which.

No. A motor moves air; the pads and the outdoor humidity decide how cold that air gets. If the cooler runs but the house is not cooling, the cause is more likely dry pads, a failed pump or a monsoon dew point than the motor. Our page on a system running while the house stays hot covers the logic.

When the cabinet or reservoir has rusted through, when the roof penetration under it is leaking, or when parts spending in one season starts to rival the cost of a new unit. Our repair-versus-replace guide puts the arithmetic in one place.
