Swamp Cooler vs. Central AC in Fort Collins

Thanks to Northern Colorado’s dry air, an evaporative cooler can be a good choice for summertime comfort. Also known as swamp coolers, these systems cool your home by passing warm air over a moistened surface. While these systems work well during dry weather, they can struggle once late-summer humidity arrives in Fort Collins.

At Balance Point Heating, Cooling & Plumbing, we can evaluate your existing heating, ventilation, and air conditioning (HVAC) system to find the best setup for your home. To learn more about swamp coolers vs. central air conditioners, read on.

Why Swamp Coolers Are So Common in Northern Colorado

Do swamp coolers work in Colorado? Yes. There is a reason so many homes in Fort Collins have had evaporative coolers for decades. These units can be highly effective at cooling homes during dry weather conditions. The evaporative cooler is designed to pull in outside air across a water-saturated pad. This causes the air temperature to fall before the fan pushes the air into the home.

A swamp cooler only works if the air is dry enough. Dry air allows more evaporation, which improves cooling. If the air becomes humid, the evaporative cooler will struggle. Because of this, certain regions are better suited to this type of technology. By understanding when a swamp cooler vs. central air conditioner makes sense, you can make the right installation decision for your family’s comfort.

How Central Air Conditioning Works Differently

Central air conditioners function in an entirely different way. The system is designed to remove heat and humidity from the indoor air before recirculating it. It does not have to constantly pull in outside air.

Even if you do not know what type of system a home has, you can generally feel the difference. A swamp cooler adds moisture, so you have to open the windows to exhaust air. In comparison, central ACs remove moisture and are intended to work with a closed house.

This essential difference is what drives all of the other variations between the two setups. Comfort during humid weather, how your home feels at night, dust levels, and pollen exposure all stem from this functional difference.

Where Each System Actually Wins 

There is not one answer to whether an evaporative cooler vs. air conditioner is better. Instead, there are a few scenarios in which each HVAC system is better suited.

When an Evaporative Cooler Wins

A swamp cooler in Fort Collins tends to be the best choice if you care about a lower operating cost on dry days and efficient performance during the dry, early months of summer. This simple mechanical design is also ideal if you prefer fresh air over recirculated air.

When a Central AC Wins

Deciding to replace your swamp cooler with an AC may be the best choice if you want a consistent level of performance no matter how humid it is outside. Additionally, the AC’s humidity removal ability can make the same temperature feel cooler and more comfortable. Central AC systems are known for having quieter operation, no seasonal shutdown ritual, and excellent compatibility with a single thermostat and zoning. Plus, keeping the house closed can help reduce dust, pollen, and smoke infiltration.

For Fort Collins and Loveland homeowners, the choice generally comes down to how you want your home to feel during the humid weeks of the year and whether you want to open your windows. If you prioritize fresh air and are comfortable with reduced performance during humid weather, a swamp cooler is an effective option. An AC is a better choice if you want to keep allergens out and enjoy all-summer comfort.

The Signs Homeowners Notice First

Often, homeowners do not make their decision about converting a swamp cooler to central air on principle. Instead, each frustration adds up until they decide to make the switch. The following complaints are the ones we hear most often:

• The house feels sticky and damp during humid stretches and does not cool down.
• Open windows can let in pollutants and irritants, such as dust, wildfire smoke, and pollen. Street noise can make it harder to sleep at night.
• Your upstairs bedrooms remain warm all night, even though the swamp cooler is running.
• If you have a rooftop unit, water staining, mineral buildup, and roof access can make a swamp cooler challenging to maintain.
• Allergy symptoms worsen during the cooling season because windows have to be left open to let outdoor air in.
• Each spring, the unit’s pad, pump, and float need to be inspected, cleaned, or replaced as needed.

What Converting to Central Air Actually Involves

Once you’ve decided between a swamp cooler and central air, the next step is planning the conversion. Switching to a central AC is a bigger project than simply replacing one cooling unit with another. How much work is involved will depend entirely on your home.

The biggest variable is your ductwork. If you already have forced-air heating ducts, these can likely carry conditioned air with a few modifications. Other homes have evaporative-specific ducting or a single large ceiling register that cannot be used with a central AC. Homes that have boilers or radiant heat will not have any ducts at all.

When we set up your new AC, we’ll need to install an outdoor condensing unit, an indoor coil or air handler, refrigerant lines, and condensate drainage. We’ll also need to install the right-sized electrical circuit for the AC. Our team will handle the removal of your old unit, sealing the opening, and any wall or roof patching needed.

Ductless mini-splits are a good option if you do not have existing ducts. However, even if you opt for ductless mini-splits instead of a central AC, you’ll still need to have the old unit removed and all of the new components installed. 

Because of all the work involved, there is no way to provide a clear scope until we’ve had a chance to do an in-home evaluation. The total cost will depend on the ductwork requirements, home size, equipment needed, layout, and electrical capacity.

If You Are Keeping Your Swamp Cooler

Whether you’re concerned about energy efficiency on dry days or prefer having your windows open, there are situations where it makes more sense to have an evaporative cooler in Northern Colorado. If you do keep your swamp cooler, there are important maintenance and care tips that you should keep in mind.

As part of your annual maintenance, you’ll need to take care of the unit’s spring startup and pad replacement. Around midseason, check the water line, pump, and float for mineral buildup, leaks, or wear. Later on, the unit must be shut down in the fall and winterized to avoid freeze damage.

Late summer is a good point to decide if you want to keep your swamp cooler for next year. If you’re ready to make the switch, Balance Point can help you plan out the conversion before the next cooling season arrives. 

FAQs

To get a better understanding of whether an AC replacement is right for you, explore some of our most frequently asked questions.

Do swamp coolers work in Colorado? 

Yes, swamp coolers generally work well through much of Colorado’s cooling season, especially during hot, dry weather. Evaporative cooling is most effective in dry air, which is why these units work well for most of the year. In mid to late summer, humidity can rise, which makes these units less effective.

Why does my swamp cooler stop working well in August?

When humidity levels rise, less moisture can be evaporated. This lowers the cooling performance of the unit.

Do I have to leave windows open with a swamp cooler? 

Yes, swamp coolers need an exhaust path, usually through partially open windows, doors, or dedicated relief vents. If you want to keep your windows closed, you’ll need to switch to a central air conditioner.

Can I use my existing ducts for central air? 

Sometimes, existing ducts from forced-air heating can be adapted for central AC units. However, a swamp cooler’s ducts are usually not possible to adapt. During an in-home evaluation, we can determine whether your ducts can be used.

Is central air more expensive to run? 

Central air is normally more expensive to run on any given day, although this can vary based on utility rates, equipment efficiency, and other factors. However, these units are able to provide a consistent level of performance on humid and dry days. Unlike a swamp cooler, they do not need water to run.
