Evaporative cooler not cooling? Usually fixed today.

Warm air from an evaporative cooler almost always means water is not reaching the pads. The pump may have failed, the float valve may be stuck, the water supply may be off, or the pads may be so clogged with scale that air passes through dry. We carry pumps and floats, so most of these are fixed on the first visit.

Once a year, before summer. The service drains and cleans the tank, checks or replaces the pads, tests the pump and float, checks the fan and belt, and runs the unit. Pads usually last three to five years depending on water quality.

A musty smell comes from stagnant water left in the tank over winter, or pads that have grown mould. A service drains and cleans the tank and, if the pads are past it, replaces them. Running the cooler on fan only for ten minutes before shutting it down in summer helps stop it coming back.

Dripping from the unit or down the ducts usually means the float valve is stuck open, the drain is blocked, or the unit is sitting out of level. All three are quick fixes on a service visit.

We do everything we can. On the first run of hot days in November and December the phone does not stop, so the earlier you call the better. Booking a pre-summer service in October avoids the queue.

If you are happy with evaporative cooling and the unit is sound, keep it. It costs far less to run than refrigerated cooling. If the unit is more than fifteen years old and failing every summer, we will price a new evaporative cooler and a split or ducted refrigerated system so you can compare.
