Swamp Cooler Cost

The average cost to install a swamp cooler is $2,440 and ranges from $1,410 and $3,469. Labor will run about $70 an hour. Materials, or the unit itself, will cost anywhere from $40 to $2,300. A larger house will have more air to cool and will therefore require a larger unit.

Swamp or evaporative coolers pull hot, dry air from outside into the home. A pad inside the unit cools and moisturizes the air, making the room more comfortable. Swamp coolers are an affordable, energy-efficient and humidifying method for cooling your home when compared with central air conditioners.

Swamp Cooler Prices

Swamp cooler prices can range from small, portable units around $40 each, to permanent, roof-mounted units at $1,600 or more. Unit cost will be determined mostly by size, location, and amount of duct work needed.

Evaporative Cooler Price List
Unit TypeAvg. Cost of Unit
Roof-Mounted$350-$1,600
Ground-Mounted$350-$1,600
Portable$40-$2,300
Window$290-$1,000

Roof-Mounted Swamp Cooler Cost

Roof-mounted units will cost about $350 to $1,600 for materials alone. Labor can be pricey for this type because of access complications. Expect to pay more if there is not already a hole in the roof for the unit to sit in. You'll also need to pay more if you don’t have a duct system installed in your home.

Cost of New Swamp Cooler Ground Unit

A ground unit swamp cooler costs roughly the same as a roof-mounted model, between $350 and $1,600. Labor charges fall between $50 and $70 per hour. Contractors charge less to install these compared to roof units because the location is more accessible. This doesn't include the cost of vents or ducts.

Cost of Ducted Evaporative Cooling

The cost to install ducting is between $400 and $900. This total includes vents, duct work and  labor, but not the roof-mounted or ground unit itself. The amount of duct work can impact both the cost of materials and labor.

Portable Evaporative Cooler Prices

A portable unit can vary in size and range in price from $40 to $2,300. These units range from small plug-in models that require little to no installation, to large systems with ducting attached.

Window Units

Window unit coolers cost as little as $290 and up to $1,000. Installation is usually a quick DIY project.

Evaporative Cooling System Size Calculator

Bigger homes require larger swamp coolers, which are more expensive. While a smaller system may save money, it's not worth the cost if it doesn't cool your home effectively. If you only need to cool a small area or room of your house, you can purchase a smaller unit.

To calculate the size you need, use the formula below.

Square footage of home times height of ceilings divided by 2
Or (sqft of home x height of ceiling) / 2

For a 1,000 square foot home with 8-foot ceilings, you would need a swamp cooler that cools 4,000 cubic feet per minute. Use this number to purchase your swamp cooler.

Cooler Coverage and Associated Costs
Area Covered (sf)Cost
100$40-$260
500$150-$580
1,500$400-$1,000
2,000$570-$2,300

Cost to Replace Evaporative Cooler

DIY vs. Hiring an Evaporative Cooler Installation Pro

If your swamp cooler involves duct work, electrical work, or is not a window installation, you should have a licensed HVAC technician in your area do the work for you. While you can save money installing a system yourself, there are some costly complications that can arise if you do the work incorrectly. These can be things like causing leaks, faulty wiring, or inefficient running that can impact your utility bills.

FAQs

How much does it cost to replace a swamp cooler with central air?

Replacing a swamp cooler with central AC will cost about $5,500. The cost to install central AC may be worth it if the cost of the water used to run the evaporative unit is expensive in your area.

 

Are swamp coolers energy efficient?

Swamp coolers are very energy efficient if installed in a dry climate, specifically in their electricity usage. Compared to an AC unit, they use 15% to 35% less power.

 

How effective are swamp coolers vs. AC?

Electrical costs are typically less expensive to run a swamp cooler than an AC, but they do use large amounts of water, especially in very dry climates. Depending on your utility costs, this may reverse any electricity bill savings the unit may provide.

Do whole house evaporative coolers work in all climates?

Evaporative coolers only work in dry climates, because they cool by moistening the air. If the air is already moist, this will not have much, if any cooling effect. If you live in a humid climate such as the eastern or western coastal regions, or the Midwest, central AC is a better choice.

How do you install a swamp cooler on a roof?

  1. Find and cut a spot in your roof/attic free of wiring and obstructions.
  2. Install metal bracing, legs, and brackets to outside roof, sealing all holes.
  3. Install ceiling duct register, duct work, power, and thermostat wires.
  4. Seal all openings and attach all duct connections according to manufacturer's instructions.
  5. Install thermostat and associated wiring as well as electrical connections.
  6. Run cool water piping to the unit and add backflow preventer if necessary.
  7. Inspect all connections and areas that could potentially leak both from the outside, in and within the system.
 

While a skilled handyman could complete this installation, it is highly recommended that you hire an HVAC professional. The unit will affect multiple systems of your house including structural, electrical, and plumbing, and imperfections could cause serious leaks or electrical problems.

How much does it cost to service a swamp cooler?

The cost to repair your swamp cooler will be between $55 and $540, depending on what is wrong with it, if you need new parts, and who you choose to do the repairs.

Where can I buy a swamp cooler?

You can purchase a swamp cooler at most local hardware stores including Home Depot, Lowe's, ACE Hardware, some Wal-Mart stores, online, and many other smaller retailers.
