Yes. Running an evaporative cooler alongside a refrigerated air system is common in Albuquerque, and when it is set up correctly it gives you the low operating cost of evaporative cooling for most of the season plus refrigerated backup for monsoon weeks and peak heat.
How a Dual Setup Works
The two systems are used seasonally rather than simultaneously. You run the swamp cooler through the dry stretch — typically May into early July — when humidity is low and it cools cheaply and effectively. When monsoon moisture arrives and evaporative performance drops, you close the cooler damper, shut the windows, and switch to refrigerated air. In fall, when the air dries out again, you can switch back.
Why the Damper Is Critical
This is where most dual installations go wrong. The two systems have opposite requirements: evaporative cooling needs windows or a relief vent open to exhaust air, while refrigerated air needs the house sealed. If the cooler damper does not seal properly, running the refrigerated system means paying to cool air that escapes straight out through the cooler opening. A properly installed motorized or manual damper solves this, and verifying it is part of any correct dual setup.
Duct Considerations
Some homes share ductwork between both systems; others keep them separate. Shared ducts are simpler and cheaper but need correct dampering and adequate sizing — evaporative systems move much larger air volumes at lower pressure than refrigerated systems do, so ducts sized for one are frequently wrong for the other. This is the same issue that trips up refrigerated air conversions, and it deserves a real evaluation rather than an assumption.
Is It Worth It?
If you already have a working evaporative cooler and are adding refrigerated air, keeping both is usually worth it — the operating cost difference during the dry months is substantial. If you are starting from scratch, weigh the cost of maintaining two systems against simply installing one well-sized refrigerated system or a heat pump.
What We Do
We design, install, and service both, and we will tell you honestly when a dual setup is not worth the complexity for your particular home. Financing is available on larger projects.
