How Swamp Coolers Work

The evaporative cooler, colloquially known as a swamp cooler, is a type of air conditioner that works well in the hot, dry air of Colorado and the Southwest. This method of pushing air over water to create a cooling effect has even been used by ancient Egyptians who hung wet blankets over doors or had servants wave fans over jugs of water.

Location Matters

Swamp coolers, despite the name, do not perform well in swampy conditions, but rather in drier climates. The name may come from the fact that they add humidity to the air.

The Evaporation Process

Liquid evaporates by releasing molecules into the air, which is then converted into gas form. The hotter, faster-moving molecules are likely to dissipate quickly, cooling off the remaining liquid and thus cooling the warm air.

Swamp Cooler Mechanics

So we know the process of water evaporation causes the air to cool, but now there needs to be a way to circulate that air in your home. The swamp cooler contains damp pads that stay moist thanks to a small pump. A blower sits at one end of the box and pulls air from outside across the damp pads and pushes the now cooled air into the house.

The A/C Difference

An air conditioner works by recirculating air through a unit that passes over a set of coils cooled by a refrigerant or coolant, such as Freon. Air conditioners are different from swamp coolers not only in their mechanics but their output—swamp coolers humidify the air while air conditioners dry the air, making the swamp cooler ideal for dry climates.

HVAC Systems—When to DIY and When to Call a Professional

Whether you live in the sweltering heat or in a veritable icebox, maintaining your HVAC system is critical to staying comfortable. There are a lot of things you can take care of yourself with regards to maintenance, but there are some things you should leave to a professional. Here are some tips for when to DIY and when to give us a call.

Do-It-Yourself Projects

Armed with the right knowledge, there are some basic tasks that you can complete to keep your HVAC system running at its peak.

  • Changing air filters – Air filters need to be replaced periodically, usually every few months depending on use. This is easy to do yourself—locate the filter located at the return intake and measure. Depending on the size of your home, you may have multiple filters and they may be different sizes.
  • Taking care of obstructions – Make sure all of your vents are clear of obstructions, including furniture and curtains. In addition, you can make sure the outside condenser unit is clear of dirt, debris, and vegetation—clear at least two feet around the unit.
  • Insulation – Proper insulation maximizes your system’s efficiency—check for air leaks, particularly around windows.

Call a Professional

It’s time to call a professional when you have any system installation or you encounter a situation where you can void your warranty. This includes electrical work and physically opening the unit—check your warranty details.

Beyond standard maintenance, any major repairs should be done by an experienced technician. In addition, your HVAC system needs an annual tune-up, for which you should also contact a pro.
