Evaporative Cooler Repair in Phoenix

How Does an Evaporative Cooler Work?

An evaporative cooler (also known as a swamp cooler or desert cooler) cools air by evaporating water. When warm, dry air passes through damp pads, it picks up moisture and lowers the temperature before circulating through your home.

This system works best in dry climates like Phoenix, helping you stay cool while adding comfort-enhancing humidity.

When Should I Turn On My Cooler for the Season?

According to Home Advisor, you should wait until outdoor temperatures reach at least 85°F before running your cooler. This timing helps cut water usage by up to 50%.

Here’s a quick start-up tip:

Turn on the water pump a few minutes before switching on the fan.

This saturates the pads for smoother, more efficient cooling.

What Maintenance Should I Do Before Summer Starts?

Before the heat hits, give your cooler a quick tune-up:

Remove the side panels and clean out any dirt or debris in the water pan.
Inspect the fan belt for proper tension — it shouldn’t move more than an inch.
Replace worn pads to keep air clean and airflow strong.
Oil the blower assembly bearings and motor if needed.
Run a short test: Make sure water is evenly distributed, check for leaks, cracks, or rust.

What If I Notice Leaks or Uneven Cooling?

If you see leaks, rust spots, or dry areas on the pads, it’s time to call in a professional. Small problems can turn into big ones if ignored, especially during Arizona’s peak heat.
