Evaporative cooling system cost by size
Evaporative cooling systems are sized by cubic feet per minute (CFM), which is how much fresh air they cycle through the home in one minute. Installing a unit too small for the space results in ineffective cooling, while choosing an oversized unit wastes energy.
| Area covered (sq. ft.) | Recommended CFMs* | Unit cost |
|---|---|---|
| Less than 250 | 200 – 750 | $100 – $400 |
| 250 – 500 | 750 – 2,000 | $100 – $700 |
| 500 – 1000 | 2,000 – 4,000 | $150 – $1,000 |
| 1,000 – 2,000 | 4,000 – 7,500 | $300 – $2,500 |
| More than 2000 | 7,500 or more | $600 – $3,000+ |
*For rooms with 8-foot ceilings
Use this formula to estimate the best unit size for the space:
Other factors that affect swamp cooler sizing include:
Ceiling height – Increase the CFM size for ceilings over the standard 8-foot height.
Sunlight – Increase the CFMs by 20% for west-facing or sunny rooms.
Room occupancy – Increase the CFMs by 20% for more than two regular occupants in the room.
Appliances – Increase the CFMs by 20% if heat-generating appliances are present, like kitchen appliances or home office equipment.

Evaporative cooler FAQs
What is a swamp cooler, and how does it work?
A swamp cooler is an evaporative cooler that blows warm, outside air over water-saturated cooling pads. The water in the pads evaporates, cooling the air by 15° to 40° F. The unit blows air into a central location or connects to ductwork, distributing the air conditioning to different rooms.
How much does it cost to replace a swamp cooler with central air?
Converting a swamp cooler to central air costs $5,000 to $8,300 when using existing ductwork. Installing new ductwork increases the conversion costs. Central air uses more power than a swamp cooler, increasing monthly utility bills.
Are swamp coolers energy efficient?
Swamp coolers are energy efficient, using 15% to 35% less energy than traditional AC units. A swamp cooler uses a small motor that operates on 115/120 volts of power, while a central air conditioner requires 240-volts.
Do whole-house evaporative coolers work in all climates?
Evaporative coolers work best in hot and dry climates, adding moisture to cool the air. Swamp coolers are ineffective in climates with humidity levels above 60% because the water can't evaporate quickly enough to provide significant cooling.
Where can I buy a swamp cooler?
Homeowners can buy a swamp cooler from a home improvement or hardware store, like Home Depot, Lowes, or Ace Hardware. Walmart and other online retailers sell portable swamp coolers.
How do you install a swamp cooler on a roof?
To install a swamp cooler on a roof, a professional installer will:
Cut a hole in the roof or attic.
Level and mount the unit using brackets and necessary bracing.
Connect the cooler to the internal duct system.
Install a thermostat and wire the cooling unit into the existing electrical system.
Run cool water piping to the unit.
Inspect and seal all connections to prevent leaks.
