Cleaning a swamp cooler is an essential part of maintaining its efficiency and effectiveness. You should clean your swamp cooler every 1-3 months, depending on usage.
Swamp coolers can harbor mold and mildew growth, which can be a health concern. Regular cleaning can help prevent this issue.
To get started, turn off the power to your swamp cooler and let it cool down completely. This will prevent any accidental start-ups or injuries.
A clogged swamp cooler can reduce its airflow by up to 50%, leading to increased energy bills and reduced cooling performance. Regular cleaning can help prevent this issue.
Preparation and Supplies
Before you start cleaning your swamp cooler, take a few minutes to prepare it for the task. Unplug the cooler and turn off the water supply to avoid any accidents or messes.
To begin, you'll need to gather some essential supplies. White vinegar is a key ingredient in cleaning a swamp cooler, as it helps loosen dirt and debris.
You'll also need a scrub brush to scrub away any tough grime. If you have hard water, you may also need citric acid to help remove mineral deposits.
The pump and float valve are also important components to inspect for damage. Cleaning the pump screen is crucial to remove any clogs and ensure proper water flow.
Before you start scrubbing, take a moment to wipe down the fan blades with a damp cloth. This will help remove any dust or debris that may be accumulated on the blades.

Pad Cleaning and Replacement
Cleaning your swamp cooler pads is crucial, especially if you live in an area with hard water like New Mexico. Hard water contains minerals like calcium, magnesium, and iron that can build up on your pads and reduce their efficiency.
You should clean your pads annually to manage this mineral buildup and remove foreign matter like cottonwood seeds. This will make the pads last longer and improve efficiency.
A water softener is a good idea if you have a Mastercool swamp cooler, as it will help your pads last the full 3-5 years. If you don't have a water softener, your pads will likely need to be replaced every year.
To clean your pads, you'll need a drill or Phillips-Head Screwdriver to open the panels, protective glasses, gloves, a ladder, hose, and flashlight. You can also use a scrub brush to clean the inside of the cooler while the pads are soaking.

Troubleshooting and Issues
If your swamp cooler isn't cooling properly, check the water flow, as a clogged intake can cause the system to malfunction.
A dirty or clogged drain pan can also cause issues, so make sure to clean it regularly.
Low water levels can cause the system to overheat, so ensure the water reservoir is filled to the recommended level.
If you notice a musty or mildewy smell, it may be a sign that the swamp cooler's pads are dirty and need to be cleaned.
Remember to clean the pads every 1-3 months to maintain airflow and prevent bacterial growth.
Draining and Cleaning the Unit
Draining the unit is a crucial step in cleaning your swamp cooler. You'll need to drain the evap cooler before cleaning it and turn off the power source for safety.
To drain the unit, follow these steps: first, turn off the power source to ensure your safety. Then, drain the evap cooler completely. It's essential to drain and dry the unit once the season is over to prevent mould and mildew in the system.
Here's a quick rundown of what to do with the unit after draining:

Now that the unit is drained and dry, you're ready to move on to the cleaning process.
Winterize
Winterizing your evaporative cooler is a crucial step to take before the cold weather hits. It's essential to get rid of minerals in the bottom tray, which can be dissolved with vinegar.
Drain the water from the bottom tray and gently scrape it out to remove any debris. This will make it easier to inspect the tray for signs of cracking.

Inspect the water trough for clogged holes and clean as necessary to ensure proper water flow. To prevent rust, coat the entire tray with submarine sealer or another product.
To prevent freezing of the cooler's water line, disconnect the water line from the cooler and blow out the water. This will help prevent damage to the line and the cooler itself.
Here's a quick checklist to help you winterize your evaporative cooler:
- Get rid of minerals in the bottom tray using vinegar.
- Clean out the tray at the bottom of the cooler.
