Swamp Cooler vs. Refrigerated Air: Which Is Right for Your Albuquerque Home?

Swamp Cooler vs. Refrigerated Air: The Albuquerque Debate

If you've lived in Albuquerque for any length of time, you've probably had this conversation. Swamp coolers have been cooling New Mexico homes for decades, and they work great — until they don't. Refrigerated air (traditional AC) offers consistent cooling but costs more to install and run.

At MGP Mechanical, we service both systems and help homeowners make the switch when the time is right. Here's an honest comparison.

How Swamp Coolers Work

Evaporative coolers (swamp coolers) pull hot, dry outside air through wet pads. As the air passes through the pads, the water evaporates and cools the air by 15 to 40 degrees. The cooled air is pushed into your home, and you leave windows cracked to let the warm air escape.

The key word is "dry." Swamp coolers work by adding moisture to the air, so they perform best when humidity is low — which is most of the time in Albuquerque.

When Swamp Coolers Work Great

In May and June, when Albuquerque's humidity is typically below 20 percent, a well-maintained swamp cooler can keep your home comfortable for a fraction of the cost of running an AC. They use about 75 percent less energy than refrigerated air, and they add moisture to the dry desert air, which can be a plus for your skin, sinuses, and wood furniture.

When They Don't

Then monsoon season hits. From late June through September, afternoon humidity can spike to 40, 50, even 60 percent. When the air is already humid, evaporative cooling can't do its job effectively. Your home feels muggy, the air never quite gets cool, and the extra moisture can actually make things uncomfortable.

Other swamp cooler limitations include the need to keep windows open (which lets in dust, pollen, and noise), water usage of 3 to 15 gallons per hour, seasonal maintenance to start up and shut down, and the potential for mold and mineral buildup on pads and in the unit.

The Case for Refrigerated Air

Refrigerated air works regardless of humidity. It provides consistent, controllable cooling with the thermostat set to an exact temperature. You keep windows and doors closed, which improves security, reduces noise, and keeps allergens out.

Modern AC systems are far more efficient than they were even 10 years ago. A new system with a SEER2 rating of 15 or higher will cost significantly less to run than older models. And with PNM rebates available for qualifying equipment, the upgrade is more affordable than ever.

The Cost Comparison

Swamp cooler installation: $1,500 to $3,500 for a new rooftop unit, including installation.

Refrigerated air installation: $6,000 to $12,000 depending on the size of your home, whether ductwork needs to be added or modified, and the efficiency rating of the system.

Monthly operating costs: A swamp cooler typically costs $50 to $100 per month to run. Refrigerated air runs $100 to $200 per month, though this varies widely based on the system's efficiency, your home's insulation, and your thermostat settings.

Making the Switch

If you're tired of monsoon season turning your swamp cooler into a humidity machine, the switch to refrigerated air is one of the most popular home upgrades in Albuquerque. The conversion involves installing an outdoor condenser, an indoor evaporator coil (usually in the existing furnace), and modifying the ductwork to work with the new system.

Many homeowners keep their swamp cooler in place and install refrigerated air as well, giving them the option to use whichever system makes more sense for the conditions. Use the swamp cooler in dry May and June, switch to AC during monsoon season.
