Viking Cooler FAQ's

All Viking model coolers come with a 6 month warranty that covers all components and telephone tech support. Where available, on-site service or repair service at our shop, is also included during the duration of the warranty (this service is currently limited to customers in the Phoenix valley area).

We maintain stock of all parts for all models advertised on our site. Common parts can be purchased directly from our website or picked up locally from our shop in Mesa, Arizona. Give us a call if you need assistance with ordering any parts not found on our website.

Ensure the display shows water in the tank (a cluster of dots at top left of control pad display). Press “COOL” button. On initial startup, the motor will delay 30-90 seconds to allow pump to prime media pad before starting automatically. Disconnect from power and reconnect if you continue experiencing trouble. This will allow the unit to reset its start-up cycle.

With proper care, your media pad can last for years. The use of hard water filters and calcium preventative tablets can help to extend the life of the pad. In locations with hard water, we recommend replacing your media pad every year or two.

Dirt, dust, and mineral deposits will accumulate in the reservoir over time. Draining the reservoir once a week and rinsing with clean water through the ice drop door will help keep all components clean and extend the life of the unit. The drain cap is located at the back of the unit at the bottom of the tank.

We offer local delivery that includes set up and operational instruction for the customer. We also offer flat rate freight delivery throughout Arizona and nationwide.

Drain the reservoir and rinse with clean water. Refill reservoir and run pump to cycle clean water through media pad for 15 mins. Shut off pump by pressing “COOL” on the control pad. Allow fan to operate until media pad is completely dry. Drain reservoir. Cover unit with Viking custom storage cover and store in dry place.

It costs less to run an evaporative cooler than an AC. They are more energy efficient because they require about 75% less electricity and limited amounts of water to run.

Any unused, unopened product may be returned within 7 days of purchase (or delivery date if shipped). Delivery and return shipping costs will be at the expense of the purchaser. Opened or used items will not be accepted for return without management approval and are subject to $125 restocking/refurbishment fee, if approved.

Answer #1 – Your cooler is equipped with a low level water sensor that will prevent the pump from running without water. The sensor is located in the lower left back corner of the water tank (if facing the back of the unit). The float on the sensor may be stuck due to mineral deposits. Disconnect power from the cooler. Remove the rear dust screen and the media pad. Move the circular part of the sensor up and down until it floats up on its own. Reinstall media pad and dust screen. Reconnect power to the cooler. Verify there are small squares visible on the upper left corner of the LCD display. Power unit on and allow cooler to perform normal start-up cycle. (Note: the sensor can usually be reached by removing the ice drop door. Disconnect power and squeeze ice drop door tabs together to remove.)

Answer #2 – If the sensor is operating correctly, replace pump.

Yes, but their effectiveness depends on humidity levels. In dry climates, they can lower temperatures by 15–40°F. However, in humid conditions, their cooling power decreases.

1. • Limited effectiveness in humid climates
   • Requires frequent water refills or dedicated water source for auto-fill
   • Can increase indoor humidity
   • Needs proper ventilation to work efficiently

1. • In high humidity (above 60%)
   • In enclosed spaces without ventilation
   • During cold or adverse weather conditions

A fan is cheaper since it only moves air, while an evaporative cooler uses water and electricity. However, a swamp cooler provides actual cooling, whereas a fan just circulates air.

It doesn’t matter—its effectiveness depends on air temperature and humidity, not direct sunlight.

When humidity exceeds 60%, the cooling effect drops significantly.

Yes, but ensure proper ventilation to prevent excessive humidity buildup as well as monitoring your water supply system in the event of water shutoff valve failure.

Yes! Swamp coolers need airflow to push out warm air and prevent humidity buildup.

It slightly lowers the air temperature but doesn’t make a huge difference. Too much ice can reduce evaporation efficiency.

1. • High humidity
   • Clogged cooling pads
   • Low water levels
   • Poor ventilation

Yes, but it depends on size and airflow. Larger units can cool up to 3,500 sq. ft..

5–20 years with proper maintenance.

Yes, but without water, it just acts as a fan and circulates air.

If not maintained properly, they can harbor mold and bacteria, potentially causing respiratory issues.

Always on while cooling. Turning it off dries out the pads, reducing efficiency and cooling effect.

Not at all! They’re still popular in many dry climates, but traditional ACs are more effective in humid areas.

1. • Mold or bacteria buildup
   • Stagnant water
   • Dirty cooling pads

Above 120°F, they may struggle, especially in humid conditions.

Near an open window or door for airflow.

Yes.

1. • Swamp coolers use evaporation
   • ACs use refrigerants and compressors
   • Swamp coolers work best in dry climates
   • ACs work in all conditions

It depends on CFM (cubic feet per minute). A 1,500 sq. ft. space needs 7,000 CFM.

Yes, they’re designed for open spaces.

15–30°F, depending on humidity.

Yes, they increase humidity, which is beneficial in dry climates but problematic in humid areas.

1. • Water source
   • Ventilation
   • Power supply

No, they’re portable and designed to move around freely.

Not recommended—ventilation is necessary.

Yes, they’re lightweight and mobile.

DIY setup—no professional installation needed.

Cleaning should be done regularly for maximum life span of components. Media pads should be replaced every season or every 3–5 years, depending on water quality.

Filtered water is best; refill as needed.

Yes, water filters should be replaced regularly.

• Drain water
• Clean pads
• Cover unit

• Check water levels
• Clean pads
• Ensure proper ventilation

50–90% less electricity than ACs.

No—just water.

200-300 kWh per year, much lower than ACs.

Yes—low energy use, no refrigerants.

Yes—lower electricity bills.
