What is a Swamp Cooler?
Swamp coolers are also known as “evaporative,” “desert” or “wet” air coolers. They’re a popular alternative to traditional home air conditioners due to their lower cost, higher efficiency and environmental benefits.
How Does a Swamp Cooler Work?
Swamp coolers work on the principle of evaporation. They use a fan to suck the warm, dry, outside air across several wet, evaporative pads. In the process, the air absorbs moisture and “chills” instantly while the water uses the heat to equalize into its gas form. After cooling the air in the central unit, the cooler uses another set of fans to circulate that cold air back through your home.
What Type of Swamp Cooler Service Do I Need?
As with conventional air conditioning systems, you’ll want to perform regular maintenance and repair so that your swamp cooler continues to cool your home properly.
To keep a swamp cooler from smelling, clean it out regularly and change the cooling pads as needed. At the end of the season, you’ll want to disconnect and clean your system to prevent winter temperatures from damaging it. Read our full blog on how to winterize your swamp cooler.
If your swamp cooler isn’t working, Applewood is available for maintenance or repair calls anytime from 6am to 10pm, 7 days a week. Look for these common swamp cooler problems and give us a call right away:
- It’s not cooling enough: If your swamp cooler is not cooling your home sufficiently, this could mean that the pads inside the unit may not be moist enough, the distributor could be clogged or something could be preventing proper airflow.
- It starts and stops constantly: A swamp cooler that frequently starts and stops could be the result of sizing issues, improperly installed parts, loose electrical connections, or motor malfunctions. If the swamp cooler itself is sound, the issue could be tied to a problem with your thermostat.
- It’s dripping or leaking: A swamp cooler dripping water or creating excessive humidity could indicate high reservoir water levels. It may also be due to a leak somewhere in the unit’s fittings and tubing.
- It smells: Stagnant water or mildew growing on the cooler’s pads could begin to produce a musty, rotten smell. Cleaning the unit and/or replacing the pads should help.
- It’s noisy: Noise issues are one of the most common swamp cooler problems , and they happen whenever a component of the system loosens, bends, breaks or wears down.
- It’s not blowing air: A swamp cooler not blowing enough air is often the sign of a faulty pump. Clean the pump and restart your cooler. If it still doesn’t work, it may be time to have one of our experts replace the pump. Additionally, check and reset the circuit breaker if it was tripped and check and replace the fuse in the unit if necessary.
