Evaporative Coolers
Swamp cooler installation, repair, and seasonal maintenance for Las Vegas homes. Desert-optimized evaporative cooling.
Evaporative coolers, swamp coolers, have been cooling Las Vegas homes since long before modern air conditioning became affordable. They work by pulling hot, dry desert air through water-saturated pads, cooling it through evaporation, and pushing the cooled air into your home. In the right conditions, an evaporative cooler can reduce indoor temperatures by 15 to 25 degrees while using a fraction of the electricity that a conventional air conditioner requires.
The key phrase is “right conditions.” Las Vegas has some of the lowest humidity in North America for most of the year, which makes evaporative cooling highly effective during spring and fall and during dry summer heat. However, during the monsoon season from mid-July through September, humidity levels can spike to 30 to 50 percent, significantly reducing evaporative cooler effectiveness. Understanding these seasonal dynamics is essential to getting the most from your evaporative cooler.
At Constant Air Balancing and Services, we install, repair, and maintain evaporative coolers throughout Clark County. Our approach combines traditional swamp cooler expertise with our NCI-certified airflow diagnostic capabilities. We verify that your evaporative cooler is delivering adequate airflow to all rooms, that the water distribution system is saturating the pads evenly, and that the system is creating the proper positive pressure in your home to drive hot air out through windows and exhaust points.
Many Las Vegas homeowners use evaporative coolers as a supplement to their central air conditioning, running the swamp cooler during dry months when it is most effective and switching to conventional AC during monsoon season. This dual-system approach can reduce cooling costs by 50 percent or more during the months when evaporative cooling is viable. We can help you design and install this type of hybrid system for maximum efficiency and comfort year-round.
System Evaluation
We assess your existing evaporative cooler or evaluate your home for new installation, considering roof type, ductwork configuration, electrical capacity, and water supply accessibility.
Pad and Motor Service
We inspect and replace cooling pads, check pump and motor operation, verify water distribution across all pads, and clean the reservoir and water delivery system.
Airflow Optimization
Using our calibrated flow measurement equipment, we verify the cooler is delivering adequate CFM to all rooms. We check duct connections and register sizing to ensure even distribution.
Seasonal Startup and Shutdown
We offer spring startup service to prepare your cooler for the cooling season and fall winterization to protect the unit during cold months, preventing freeze damage to the water system.
Performance Verification
We measure temperature drop across the pads, verify airflow delivery to each room, and confirm the system is creating proper positive pressure for effective cooling throughout your home.
Desert-Optimized Performance
We understand Las Vegas humidity patterns and can help you maximize evaporative cooler effectiveness during the months when conditions favor this technology.
Airflow Expertise
Our NCI-certified airflow testing ensures your evaporative cooler delivers adequate cooling to every room, not just the rooms closest to the unit.
Hybrid System Design
We can design and install dual-system configurations that switch between evaporative and conventional cooling for maximum efficiency across all seasons.
An evaporative cooler is a great fit for the dry Las Vegas spring and early summer, but only when the pads, the water system, and the airflow are all working together. A swamp cooler that is starved on water or pushing air through crusted pads is just an expensive fan moving warm air.
We service and install evap coolers with the pads, pump, float, and bleed-off all set right, then confirm the unit is actually moving the cool air it should. A properly tuned cooler can drop incoming air 20 to 30 degrees, which is real relief during the part of the year humidity stays low. We will also give you a straight answer on when an evap cooler is the right call and when the valley humidity has climbed enough that you want refrigerated air.
Honest advice on which cooling fits your home, not a one-size pitch. See cooler work in the gallery.
My swamp cooler was barely doing anything. They replaced the pads, fixed the water system, and checked the airflow, and now it cools the house great in the spring. They were also honest that I would want to run the AC once the humidity climbs.
