It’s Getting Hot – Evaporative Cooler Startup

With the days and nights getting warmer it is time to start thinking about changing over from heating to cooling. The general time for this to happen is April/ May. Some like to get a jump on cooling and don’t mind if it gets a little chilly and others want to stay warm without any fear of a last storm making them too cold. This is a personal preference and can be scheduled to comply with your needs. The steps to follow are as follows:

1. The heater is shut down, gas turned off and dampers put into place or opened depending on your system.

2. Power is restored to the units and fuses replaced if needed.

3. The water line and float shut offs are usually replaced every year to minimize the potential for leaks.

4. The water is turned on, and system flow is checked through the pump and the distribution lines to the pads.

5. The units are checked for leaks and rusted spots requiring repair or replacement.

6. The pads are changed every year in our area as our hard water really tends to slow the air flow.

7. We check for wear on the motor belts and repair and adjust as needed.

8. We oil any bearings on moving parts as needed, this is not as common as it used to be as most motors are sealed and do not need lubricant.

Once these steps are complete you are ready to cool down. Keep in mind that the coolers operate on evaporation. The pump should run for a while before turning on the fan to start water flow through the pads. Also if the humidity gets high evaporative coolers do not perform as well. When it is time to replace your evaporative unit it might be a good time to look into upgrading to a package unit which can heat and cool no matter what the humidity is. Call us to schedule a changeover or to quote a combo unit upgrade.

If cool air is not flowing here are some things to fix:

1. Check water flow, is it on?

2. Is there a clog in any of the lines?

3. Is the fan actually running?

4. Is the pump flowing water to the pads?

5. If nothing is running it could be electrical power, check the fuses.

6. If fuses are ok it could be a motor or belt.

7. If you can’t solve it give us a call.
