How Much Does a Pool Chiller Cost? [2025 Data]

Pool Chiller Cost Factors

There are two major costs associated with pool chiller installation: the cost of the pool chiller and the cost of labor. Here are some cost factors to consider.

Type

There are three different types of pool chillers. Evaporative chillers are the most affordable but can be less effective than mechanical pool chillers. Meanwhile, hybrid chillers are the most costly but offer heating as well as cooling.

• Evaporative Pool Chillers: Evaporative pool chillers cost $1,000–$3,000. They use a pump to pressurize water into a mist, then a fan to blow the mist over the pool's surface. The mist evaporates, absorbing the heat from the pool's surface in the process.

• Mechanical Pool Chillers: Mechanical pool chillers cost $1,500–$6,000. They use refrigerant to cool water. These coolers are like air conditioning for your pool and work better than evaporative coolers in humid climates.

• Hybrid Pool Chillers: Hybrid pool chillers cost $2,000–$8,000. They’re a combination of a chiller and a heat pump and can heat and cool your pool.

Pool Size

You’ll need to choose a pool chiller with the capacity to cool the volume of water in your pool. The larger your pool, the more the chiller will cost. The average residential pool holds 10,000 to 20,000 gallons of water, but commercial pools or large residential pools may hold more.

Manufacturer

There are various brands of pool chillers. A higher-end brand will cost more, though some manufacturers offer seasonal sales. The leading brands include Glacier Pool Coolers (which are among the most affordable) and AquaCal (which offer a range of chillers and hybrid chillers). You’ll also find GulfStream, FibroPool, and Raypak topping best of lists.

Labor

If you hire a pool contractor to install your pool chiller, you can expect to spend $500 to $1,500 on labor. Most pool contractors charge $50 to $150 per hour. The more complicated the installation, the more time it will take and the more it will cost.

Pool Chiller Ongoing Costs

The cost of a pool chiller includes the installation and the chiller unit itself, as well as a couple of ongoing costs to consider.

Electricity

Similar to a pool heater, a pool chiller runs on electricity. Running your new pool chiller will raise your electric bill. For most homeowners, the added electricity cost per month for a pool is somewhere between $10 and $300. The amount depends on the following factors:

• Desired Temperature: The optimal temperature for a recreational swimming pool is between 78–86 degrees. The more you need to lower the temperature, the more it will cost to run the cooler.

• Pool Size: It takes more energy to cool a larger pool with a higher volume of water. 

• Location: If you live in a hot and sunny climate, your pool may warm up quickly. As a result, your pool chiller will need to use more energy to maintain the optimal temperature.

• Efficiency: High-end chillers may cost more up front, but they’re more energy efficient and could cost less than $1 per day to run. Look for a model with a high Coefficient of Performance (COP) rating.

Maintenance 

If you hire a pro for swimming pool maintenance, you’ll spend around $100 to $300 per year maintaining your pool chiller (on top of regular pool maintenance costs). On the plus side, chillers can help prevent algae growth and save you on the cost of additional pool chemicals. Most chillers last 10 to 20 years before you’ll need a replacement. 

DIY Pool Chiller vs. Hiring a Pro

If you want to save on the cost of a pool chiller, there are some relatively straightforward DIY options. The most common are fountains that you hook into your jets or existing pumps. They cool using evaporation, but they’re not as effective as the type of pool chillers that require professional installation. 

In a climate that doesn’t get too warm, a DIY pool chiller may work well alongside other measures, like shading or covering your pool and running the filter at night. If you live in a hot climate and need to reduce your pool temperature by more than a few degrees, it’s a good idea to hire a local pool contractor to install a more effective chiller that allows you greater temperature control. 

Ways to Save Money on a Pool Chiller

If you’re budgeting for the cost of installing a pool, you may be looking to cut your spending anywhere possible. In truth, a pool chiller is only necessary in really warm climates. Nonetheless, if you really want to keep your pool water at an optimal temperature, there are a few things you can do to cut down on the cost of a pool chiller:

• Size Matters: Choose the smallest size chiller that can effectively cool your pool. The best option depends on the size of your pool and the volume of water you need to cool.

• Choose an Evaporative Chiller: Evaporative chillers are more affordable than other types. Some evaporative chillers are relatively simple to install DIY if you’re a handy homeowner.

• Two for One Can Save You Cash: If you don’t already have pool heating and would like to install it in the future, opt for a hybrid chiller to get the biggest bang for your buck.

• Look for Sales: Pool chillers often go on sale during the fall and winter, when people are less likely to take on pool-related projects.

• Balance Brand and Efficiency: Instead of opting for the lowest-cost chiller, look at which models will provide the most value over time. A mid-range model from a reliable brand will likely have a longer lifespan and require fewer repairs than lower-cost options. Your pool contractor can recommend the right brand for your goals.

• DIY Maintenance: Saving money on a chiller isn’t just about up-front costs. You can save on the cost of maintaining your pool by doing some of the work DIY. Clean your pool and balance the chemicals on your own, but tap in a pro when you need repairs.
