Is It Cheaper To Run A Swamp Cooler?
Swamp coolers, despite the name, aren’t for humid environments! These evaporative coolers are popular in dry areas, like New Mexico, where their efficiency shines. But is their popularity matched by their cost effectiveness?
Robbins Heating & Air Conditioning is here to reveal the cost differences between swamp coolers and refrigerated air conditioning systems to help you find the right fit for your home.
How Does Evaporative Cooling Save Energy?
Evaporative cooling, or swamp cooling, operates with fewer mechanical parts, reducing energy needs. Unlike refrigerated air systems that rely on refrigerant, compressors and blower motors, swamp coolers use only water and a blower fan to create cool air. Here’s how it works:
- Minimal parts — Swamp coolers don’t use compressors or refrigerant. They only need a water pump and a blower fan.
- Cooling through evaporation — Warm air passes over a water-saturated cooling pad, where it evaporates and cools the air before pushing it into your home. This natural cooling process requires significantly less electricity than a refrigerated air conditioner.
Additional Costs To Consider With Swamp Coolers
Despite lower monthly electricity costs, evaporative coolers can come with hidden expenses:
- Temperature control challenges — Swamp coolers don’t allow precise temperature control, so you might not always get the comfort you’re after.
- Increased costs during humid weather — Swamp coolers are less effective during humid weather, such as monsoon seasons in New Mexico. To compensate, some homeowners install window air conditioners for temporary relief, though these units are typically less efficient and effective than central air.
Refrigerated Air Conditioning vs. Evaporative Cooling
Swamp coolers are often more cost-efficient than refrigerated air conditioners. Refrigerated systems excel in high humidity and offer consistent performance, but they do have higher installation and operational costs. For many homeowners, it will come down to the low expense of a swamp cooler compared to the added control of a refrigerated system.
Quick Comparison: Swamp Cooler vs. Refrigerated Air
| Criteria | Swamp Cooler | Refrigerated Air |
|---|---|---|
| Initial Cost | Lower | Higher |
| Monthly Energy Cost | $20-$30 | $50-$100 |
| Effectiveness in Humid Weather | Limited | Consistent |
| Best For | Dry climates like New Mexico | Any climate, including humid |
| Maintenance | Regular water source required | Annual tune-up recommended |
Choosing The Right Cooling System For Your New Mexico Home
Swamp coolers and refrigerated air systems each offer unique benefits depending on your needs and budget. For dry climates like New Mexico, swamp coolers are a cost-effective choice, but refrigerated air may offer more reliable comfort during humid conditions. If you’re uncertain which system would best suit your home, contact a local HVAC technician for guidance.
