Hessaire evaporative coolers, often referred to as swamp coolers, have become a popular choice for homeowners and businesses looking for an energy-efficient way to stay cool. Unlike traditional air conditioning systems that use refrigerants and compressors, these units use the natural process of evaporation to lower air temperature. This method is not only more environmentally friendly but also significantly cheaper to operate in dry climates.
Finding the right Hessaire unit or the specific replacement parts to keep an existing one running smoothly requires a bit of knowledge about how these systems function. Whether you are looking to purchase your first portable cooler or need to fix a unit that has been in service for years, this guide provides the straightforward information you need to make an informed decision.
Choosing the Right Hessaire Swamp Cooler
The most important factor when buying a new evaporative cooler is ensuring it is the correct size for the space you intend to cool. If the unit is too small, it will struggle to lower the temperature effectively. If it is too large, it may create excessive humidity without providing additional comfort.
Understanding CFM Ratings
Evaporative coolers are rated by CFM, which stands for Cubic Feet per Minute. This measurement indicates how much air the fan can move through the cooling media every minute. To find the right CFM for your room, you can use a simple calculation.
- Measure the square footage of the room (Length x Width).
- Multiply that number by the ceiling height.
- Divide the total by two.
For example, if you have a 400-square-foot room with 8-foot ceilings, the total volume is 3,200 cubic feet. Dividing by two gives you 1,600, meaning you should look for a unit rated for at least 1,600 CFM. Hessaire offers a wide range of models, from small units around 1,300 CFM to industrial-sized coolers exceeding 11,000 CFM.
Indoor vs. Outdoor Use
Hessaire coolers are versatile, but some models are better suited for specific environments. If you plan to use the cooler on a patio or in a garage, look for models with rugged wheels and UV-resistant plastic housings. For indoor use, consider the noise level and the footprint of the unit to ensure it fits comfortably in your living space.
Where to Purchase New Units
Because Hessaire is a leading brand in the evaporative cooling industry, their products are widely available through various channels. You can typically find them at major home improvement retailers, both in-store and online. Buying from a local retailer can be advantageous if you want to see the unit’s size in person before committing.
Online marketplaces are also excellent sources for new units. These platforms often provide a broader selection of models and allow you to compare prices across different sellers. When ordering online, pay close attention to shipping costs, as these units can be bulky and heavy.
Finding the Correct Replacement Parts
Like any mechanical device, a swamp cooler requires regular maintenance and the occasional part replacement. Because Hessaire units are designed for longevity, most components are modular and easy to swap out. This makes it simple to repair a unit rather than replacing the entire machine.
Identifying Your Model Number
Before you begin searching for parts, you must identify your specific model number. This is usually found on a silver or white sticker located on the back or side of the unit. Common model prefixes include MC (Mobile Cooler) followed by a number representing the approximate square footage or CFM capacity, such as the MC18, MC37, or MC61.
Essential Parts to Keep on Hand
While most parts of a Hessaire cooler will last for years, some components are considered consumables or are more prone to wear and tear. Having these parts available can prevent downtime during a heatwave.
- Rigid Media Pads: These are the cooling pads that hold water. Over time, they can become clogged with mineral deposits from hard water, which reduces airflow and cooling efficiency.
- Water Pumps: The pump is responsible for moving water from the reservoir to the top of the media pads. If the pads are dry while the fan is running, the pump may need to be replaced.
- Float Valves: This component regulates the water level in the tank. If your unit is leaking or the tank isn’t filling properly, the float valve might be stuck or broken.
- Fan Motors: While less common, the motor may eventually fail. Replacing a motor is a more involved repair but is still manageable for most DIY enthusiasts.
How to Replace Hessaire Cooling Media
The most frequent maintenance task you will encounter is replacing the cooling media. Depending on the quality of your water and how often you use the unit, you should expect to replace the pads every one to two seasons. Using a water treatment tablet can help extend the life of these pads by reducing scale buildup.
- Ensure the unit is unplugged and the water supply is turned off.
- Remove the screws holding the back or side panels in place.
- Carefully pull the old media pads out of the frame.
- Slide the new pads into position, ensuring they are oriented correctly (usually indicated by arrows on the side of the pads).
- Reattach the panels and test the unit to ensure even water distribution across the new media.
Troubleshooting Common Issues
If your cooler isn’t performing as expected, there are a few simple things to check before buying replacement parts. First, ensure the unit is placed near an open window or door. Evaporative coolers require a constant supply of fresh air to function; if used in a sealed room, they will simply increase the humidity until the air feels damp and heavy.
