You can replace a swamp cooler with air conditioning, but it is a replacement, not a conversion of one part. An evaporative cooler and a refrigerated system work on different principles, so the roof unit comes out, the ducts are reviewed, a return path is added, and new equipment goes in with its own electrical and permit requirements. In Colorado Springs, the work is very doable, and it is usually priced as a full installation.
Below we walk through what changes in the house, what the permit looks like, what drives the price, and how to decide whether to switch now or keep the swamp cooler a little longer.
TL;DR
- A swamp cooler cannot be converted into an air conditioner by swapping one component. The unit is removed and refrigerated equipment is installed in its place.
- The main jobs are removing the cooler, sealing the roof opening, checking or reworking the ducts, adding return air, and providing a dedicated electrical circuit.
- Replacing a system with air conditioning requires a permit from the Pikes Peak Regional Building Department.
- Our published starting prices for a new air conditioner run from $5,500 to $6,500 for single-stage models. Ductwork and electrical needs can move the final number.
- A load calculation, not the size of the old cooler, should decide the size of the new system.

Can a swamp cooler be converted to air conditioning?
Not in the way people hope. There is no kit that turns a swamp cooler into an air conditioner. An evaporative cooler pulls outside air through wet pads and pushes cooled, moist air into the house. An air conditioner moves heat out of the house with refrigerant and recirculates the same indoor air. Almost nothing inside the two machines is shared.
What carries over is the house itself: the duct trunk, the ceiling registers and the general location of the equipment. Whether those parts can be reused is a question for a site visit, not a phone estimate. Some homes reuse a good part of the existing ducts. Others need a new layout because the old ducts were sized for a much larger volume of air than refrigerated systems use.
So when we say conversion, we mean a complete project: take out the old system, prepare the house, install the new one, and commission it.
Why Colorado Springs homeowners make the switch
Swamp coolers suit the Front Range for much of the year. Evaporative cooling works best in dry air, and the Building America Solution Center notes that evaporative coolers can use about one-fourth the energy of central air conditioners in dry climates. That is a real advantage, and it is why so many homes here still have one.
The reasons to change usually fall into a few groups:
- Late summer humidity. When monsoon moisture moves in, an evaporative cooler has less to work with, and a house can feel warm and damp at the same time.
- Open windows. A swamp cooler needs a window or two open to let air out. That is a poor fit for homes with wildfire smoke days, pollen, dust, noise concerns or security worries.
- Cabinet and parts age. Rusting cabinets, frequent pad and pump service and rooftop work every spring and fall add up.
- Resale and comfort. Many buyers expect a thermostat and closed windows.
- Allergies and air quality. Closed-house cooling is easier to pair with filtration. If this matters to you, our indoor air quality services can be planned into the same project.
If you are not sure your cooler is ready to retire, our swamp cooler buying guide for Colorado homes and our notes on how to maintain swamp cooler systems cover the keep-and-service side of the decision.
When repair makes sense and when replacement is the smarter call
Repair usually makes sense when the unit is fairly young, the cabinet is sound, and the problem is a pad, a pump or a float valve. These are ordinary wear items, and fixing them is inexpensive compared with a new system.
Replacement is the smarter call when several of these are true:
- The cabinet is rusting through or the roof curb is deteriorating.
- You are servicing the unit more than once a season.
- The house is uncomfortable during humid weeks, and the problem repeats every year.
- You want to keep windows closed for air quality, noise or security.
- You are already planning a new roof, a remodel or an electrical upgrade, and the work can be combined.
Wear tends to spread in an older system. A new pump this year is often followed by a motor, a pulley or a rusted pan the next. When the repair list starts to look like the beginning of a longer one, it helps to price the replacement alongside the repair so you can compare real numbers.
What the conversion actually involves
Every house is different, but the sequence is consistent. Here is what happens on a typical swamp cooler to central AC job.
Removing the cooler and closing the roof
The old cooler is disconnected from water and power and lifted off. That leaves a large opening in the roof or wall and a duct drop below it. The opening has to be framed, patched and waterproofed so it is as weathertight as the rest of the roof. This is the step we do not rush, because a poor patch shows up as a leak the first heavy storm.
Reviewing the ducts
Swamp coolers move a lot of air through large ducts and push it out through open windows. Central air runs on a closed loop with a smaller volume of cooler air. That changes what the ducts need to do.
The supply ducts should be sized to the new equipment, sealed at the joints and insulated where cold air could cause condensation. The house also needs a return path so air can get back to the unit. Many swamp cooler homes do not have return ducts at all, because the house was relieved through windows. Adding return air is one of the most common surprises in these projects, and it is part of the reason a site visit is worth doing before you commit to a number.
Duct condition is the biggest variable. Ducts in good shape can often be adapted. Damaged, undersized or poorly routed ducts are better replaced while the ceiling and attic access are already open.
Installing the new equipment
A central air system has an outdoor condenser and an indoor coil, usually paired with a furnace or air handler. If your home has a furnace, the coil can often be set on it. Copper refrigerant lines connect the indoor and outdoor parts, and a condensate drain carries away the water the coil removes from the air. That is a new requirement compared with a swamp cooler, which uses a water supply instead.
If you also need a new furnace, doing both at once usually makes sense. Our HVAC system replacement page explains how furnace and AC packages are planned together.
Electrical work
Most swamp coolers run on a standard 120-volt circuit. A central air conditioner typically needs a dedicated 240-volt circuit, a disconnect near the condenser and correct breaker sizing. In some older homes, the main panel does not have room or capacity for the new load, and a panel upgrade becomes part of the project. We check this on the first visit, because it can change both the schedule and the budget.
Commissioning
At the end, the system is started, the refrigerant charge and airflow are verified, thermostat settings are programmed, and the old equipment is hauled away. You should leave the job knowing how to set the thermostat, where the filter is and what the maintenance schedule looks like.
Time on site depends on the scope. A house with usable ducts and a simple electrical hookup goes faster than one needing a new duct layout and a panel upgrade. We give a realistic schedule after seeing the house.
Permits and inspections in Colorado Springs
This is a regulated project. The Pikes Peak Regional Building Code requires a permit before installing, replacing or repairing a regulated electrical, gas, mechanical or plumbing system. The code also contains an exemption for evaporative coolers on one- and two-family dwellings “where no structural elements or components are modified.” That exemption is written for evaporative equipment. A refrigerated system, a new circuit and possible roof or framing work are a different matter.
The Pikes Peak Regional Building Department’s homeowner permit guidance lists air conditioning installation and replacement among the projects that need a permit. We handle the permit and inspection scheduling as part of an installation, so you do not have to navigate it. If you are comparing bids, ask every contractor who pulls the permit. An unpermitted job can cause trouble later with inspections, insurance and a home sale.
Outside the city limits, such as Falcon, Ellicott or Victor, the permitting setup may differ by jurisdiction. We confirm what applies to your address before work begins.
How much does it cost to replace a swamp cooler with AC?
The cost is the equipment plus the work that makes the house ready for it. The equipment price is easy to see. The preparation work depends on your roof, ducts and panel.
Here are our published starting prices for central air equipment, as listed on our site in November 2026. Each is a starting point, and your final quote depends on the home.
| System | Starting price |
|---|---|
| 14 SEER2 single-stage air conditioner | from $5,500 |
| 16+ SEER2 single-stage air conditioner | from $6,500 |
| 15 SEER2 single-stage heat pump | from $6,500 |
| 17 SEER2 three-stage heat pump | from $8,500 |
| 18 SEER2 variable heat pump | from $10,000 |
You can see the current details on our air conditioner pricing page. We use flat-rate pricing, so the quote you approve is the price for the scope we agreed on.
Three things move the number most in a swamp cooler conversion:
- Ductwork. Usable ducts keep the price down. New supply and return ducts add to it.
- Electrical. A new dedicated circuit is routine. A panel upgrade is an additional item.
- Roof and ceiling. The size and condition of the old cooler opening and any repair around it.
A higher efficiency or variable-speed system costs more up front. It also runs more evenly, which tends to matter in a home that has been cooled by a simpler system. For a more detailed breakdown by system type, see our page on AC replacement cost in Colorado Springs.
Choosing and sizing the new system
Do not size the new air conditioner by the old cooler. Swamp cooler capacity is measured in airflow, not tons of cooling, and the two numbers do not translate.
The right size comes from a load calculation: square footage, insulation, window area and type, the direction the house faces, sun exposure and the local climate. An oversized system cycles on and off, cools unevenly and leaves the air less comfortable. An undersized one runs constantly and struggles on the hottest afternoons. At roughly 6,000 feet, Colorado Springs also has thinner air and a cooler overnight temperature swing than many places that AC marketing is written for, which is one reason local experience matters in selecting equipment.
Before a contractor leaves your house, you should have answers to these questions:
- What size was calculated, and from what measurements?
- What happens with the ducts and the return air?
- Is the electrical panel adequate?
- What does the quote include for the roof patch, permit and haul-away?
- Which efficiency level is being quoted, and what are the alternatives?
A single-stage air conditioner is the simplest and least expensive option. A two- or three-stage or variable system fits homes where steady, quiet operation matters more. If you also heat with a gas furnace, pairing the air conditioner with a new furnace can make sense when the existing furnace is near the end of its life. Our HVAC system packages show how those combinations are put together.
Heat pumps deserve a look as well. A heat pump cools in summer and can provide part of your heating in cooler weather, so it may be a fit if you want one system doing both jobs. We can walk through how that compares with an AC and furnace pairing for your home.
Can you keep the swamp cooler and add AC?
Some homeowners keep the cooler for dry spring weather and add refrigerated air for the humid stretch. That can work, but the two should never run together. A swamp cooler adds moisture to the house, and an air conditioner is trying to remove it, so they fight each other and waste energy. If you keep both, you need a clear way to use one at a time, and the swamp cooler should have its own ducting or a damper arrangement that keeps it separate from the AC ducts.
The tradeoff is that you keep maintaining two systems, and the cooler’s roof opening remains a possible leak point. Most of our customers who go this route do it temporarily, to spread the cost over a couple of seasons. If you are weighing it, we can lay out both paths with real figures.
Our perspective on swamp cooler conversions
We have been doing heating and cooling in Colorado Springs for a long time, with more than 40 years of combined experience on our team. That has taught us that a swamp cooler conversion is not a product sale. It is a building project that happens to end with a new air conditioner.
The best installations start with the house. We look at the roof, the ducts, the return air path and the panel before we talk about equipment. Our NATE-certified technicians do the work, and we stand behind it with a workmanship guarantee.
We price our work as flat-rate, upfront numbers. If the scope changes because we find something in the attic, you hear about it before work continues, not on the final invoice. We think that is how a veteran-owned local company should treat the people who let it into their homes.
Our approach to equipment is the same. We design the system for Front Range conditions and high altitude, then we install it correctly the first time. If you are going to put in new cooling after years with a swamp cooler, it should be a system you do not have to think about again.
Owner
Plan your replacement with Strong Heating And Cooling
If your swamp cooler is nearing the end of its life, or you are simply ready for closed-window comfort, we can look at your home and give you a flat-rate quote for replacing it with central air. We handle the roof closure, ductwork review, electrical, permit and installation, and we can include a new furnace if that suits the house.
See our air conditioner installation services, browse the AC pricing page, or reach us through our main site to schedule a visit. We also offer maintenance plans, so the new system stays in good condition after install.
Frequently asked questions
Can I convert my swamp cooler to AC without replacing the ducts?
Sometimes, if the ducts are sealed, correctly sized and in good condition. Even then, central air needs a return path and insulated supply ducts to avoid condensation, and many swamp cooler homes lack both. We inspect the ducts on the first visit and tell you what can stay.
Do I need a permit to replace a swamp cooler with air conditioning?
Yes. The Pikes Peak Regional Building Department lists air conditioning installation and replacement among the projects that need a permit. The evaporative cooler exemption in the code does not cover a refrigerated system. We pull the permit and schedule the inspection for our installs.
Will my electric bill go up after switching?
It is likely to rise in the hottest weeks, because evaporative coolers use much less energy in dry climates. The Building America Solution Center puts them at about one-fourth the energy of central air. A properly sized, higher-efficiency system, a good duct system and a well-set thermostat help keep that difference manageable.
Can I run my swamp cooler and AC at the same time?
No. The cooler adds humidity while the air conditioner removes it, so each undoes the other’s work. If you keep both, run one at a time and keep their ductwork separate.
How do I know what size air conditioner I need?
It comes from a load calculation that looks at square footage, insulation, windows, orientation and sun exposure. Do not use the old cooler’s size as a guide. We perform the calculation during the estimate.
