What Exactly Is a Swamp Cooler?
We live in a very hot climate, obviously. That means that you not only need a great air conditioner that will reliably cool your home, but you also want one that won’t cost too much to run. After all, you don’t want to be draining your budget just to live comfortably.
Because we also live in a very dry climate, though, you really don’t want your air conditioner drying out the air in your home further. During the cooling process, as refrigerant evaporates and draws heat out of the air, moisture condenses and is drained away by a traditional AC. How do you prevent your air from drying out excessively? You could use a humidifier, or you could use an entirely different cooling process — one that actually helps you to add humidity to the air.
How Does It Work?
Very simply, actually. Unlike a traditional central air conditioner or heat pump, an evaporative, or swamp, cooler does not rely upon a refrigeration cycle in order to remove heat from the air in your home, disperse it outdoors, and recirculate cooled air throughout the house. In fact, the evaporative cooler shares more in common with a humidifier than it does with a traditional AC, to a certain degree.
Ideal for climates like ours where humidity levels tend to be low, an evaporative cooler actually cools air coming into the house by releasing humidity into it. Air is drawn in from outdoors, and is passed over water-saturated pads in the cooling system. This causes water to evaporate into the air, cooling it by 15-40 degrees in the process.
Great Energy Efficiency Awaits!
Because there is no refrigerant cycle to facilitate, swamp coolers use far less electricity than traditional air conditioners do. Keep in mind that you are only going to get the most efficient and reliable performance possible from your system if it is of the right size for your home, installed properly, and regularly serviced. Due to the element of water in the cooling system, evaporative coolers actually require more maintenance than standard central ACs.
Pads have to be replaced, generally at least twice throughout the cooling season. There are filters that will have to be replaced, a reservoir to clean, and a pump that will need to be kept in prime working condition. You should also remember that not all swamp coolers are as efficient as others. The process is inherently efficient, but newer, two-stage models using a pre-cooler are even more effective and can save you more energy.
So Too Does Great Indoor Air Quality!
When you run a swamp cooler, you actually need to leave your windows open a bit in order to bring in fresh air that can be passed through the cooler. When you compare this to the operation of a central AC, which will usually lead homeowners to seal up their homes to conserve energy, the advantage in terms of air quality is clear.
Not only will a swamp cooler keep your home cool and comfortable efficiently, but it can also keep the air well-humidified and of a high quality. They’re not right for every home or situation, naturally. If you think that you could benefit from the use of an evaporative cooler, though, be sure to give us a call and have the job done right.

What Our Customers Say About Us



Thank you Preston








I appreciated the friendly and knowledgeable service provided by Perter and my new system was installed the next day. The crew that came out was very prfessional and efficient. My home was cool within few hours of the work being completed and detalied instructions were givien to me on how the system works and if I were to have any questions I could call day or night and get the answers needed.
I have recommended your company to a few homeowners I know that are in need of system service and/or repairs. You have gained a customer for as longas I live here in the San Antonio area.




Dylon the plumber came out to check my plumbing. Confirmed my water heater is old enough to be replaced and that some valves are original and are showing some corrosion.
On 7/25 Noe came to my house and confirmed that my A/C needed to be replaced. Austin was able to find a Payment Plan that I qualified for the same day. On 7/26 Christian installed my new A/C unit and a new thermostat. He showed me how to use it and left the manual. Everyone at Goettl was so helpful with this situation and got my A/C replaced and running in just two days!
On 3/9/2024 Jesse came to my house for the heater rejuvenation and to install the Sadie Smart monitor. He was very thorough in explaining how the Smart system works and where he had placed all of the sensors. I had a new filter so he replaced the old one. He also told me that my plan covers filters and I just pay for shipping; I'll remember that when I need a new filter.
On 1/11/25 Jesus came to my house for the annual heater rejuvenation and said my unit is in good shape and running well. I had bought 2 filters before the service in March 2024, one was installed then. Jesus installed the one I had on hand and reminded me that my plan covers filters. He was also thorough in going over the readings he had taken.
On 5/3/25 Michael came to my house for the annual plumbing inspection provided with my Sadie Guard Dog Protection. My water heater is about 7 years old and Michael answered my questions about replacing it. He also told me that Goettl could remove the old one and install new one if I found one more in my budget somewhere else. He even told me the estimated install cost to help with my budgeting.
Andrew came to my house 10/11/2025 for the semi-annual HVAC service under my Sadie Guard Dog Protection. He told me the unit is continuing to function well and needs no repairs.



Professional, knowledgeable and efficient. Very polite and courteous
Also installed surge protectors on the the condensers







Mike was absolutely Top Notch!! He arrived at 9:00 pm in a great mood, then took care of business and left in a great mood..Two thumbs up!!

Also, we are apart of the Smart Sadie Program and just received our yearly plumbing rejuvenation and we had the pleasure of meeting our Tech, “Frank M”. He was so knowledgeable and taught me and my Husband so many things we didn’t know which we value so much as we are new home owners and are just kind of wingin’ it! You can really tell that the Techs and the company genuinely cares about their Clients, and I will be requesting Frank M to service the Plumbing needs within my home from this point on! Frank is the man, and we loved him!(:
So now we have Christian and Daniel for our HVAC maintenance and servicing and Frank M for all our Plumbing Needs! We have an amazing team and I’m sure that other Clients feel the same way about their Techs as well!
Love this Company!


We’ve been Goettl customers for years and have always appreciated their service, but Kevin Edwards truly raised the bar. During his visit yesterday, Kevin showed outstanding attention to detail and technical expertise. He thoroughly inspected every part of our HVAC system, documenting his findings with photos and clearly explaining issues that had gone unnoticed through several previous service visits.
Kevin discovered that our HVAC system had been improperly installed when the home was built—something no other technician had identified. He explained how that flaw had created a chain of problems affecting the furnace, cooling system, and overall efficiency. Because the system uses an outdated refrigerant, repairs weren’t a viable long-term solution, and Kevin guided us toward a responsible upgrade plan.
While no homeowner wants to replace a system after only seven years, we’re grateful Kevin uncovered these hidden issues before they caused a catastrophic failure. His thoroughness, honesty, and professionalism turned a potential headache into peace of mind. Kevin is an exceptional representative of Goettl, and we recommend him without hesitation.

I want to express my complete satisfaction with the work performed by Frank Piusseaux, a technician from Goettl.
For months, several technicians tried to identify the issue with my air conditioning unit, but no one could solve it. However, from the moment Frank arrived, he showed great professionalism and dedication. He took the time to carefully investigate the cause of the problem and determined that the issue was a short circuit in the wiring between the thermostat and the unit.
Thanks to his knowledge and effort, my air conditioning system is now working perfectly.
I truly hope that Goettl recognizes the value of having such a skilled, responsible, and committed employee. Technicians like him make a real difference and deserve special recognition, even a financial incentive, for the value they bring to the company.
Thank you very much, Frank, for your excellent work!





Team Nacho and Brayan installed a 4 ton unit, very professional, very courteous, explained operation as well as answered our questions. Nacho and Brayon cleaned up as if they weren't here. We would certainly utilize their services again.







David and Cesar worked on my water heater and they were all amazing. Great prices and work with me! Will be going to them in the future

Corey 4,17,2025 Master of flow 6 star toilet fixer plus. Thanks
10/9/25 Daniel great service very friendly and knowledgeable. Furnace Thanks

To my surprise, the rep came out within a hour or so - that same morning. He educated me on a few tips - like not needing to shut off the water to the entire house in a situation like this - and a few other tips, but as for the water heater - it was toast and already beyond the warranty it had.
There was zero sales pressure for a specific water heater - and instead, he spent quite a bit of time with my wife and I going over the many different options they had for replacing one.
Once again to my surprise, after we picked one - he was already on the phone with a crew and the installation was set for that same day - no extra charges for an emergency situation or anything like that. The crew came out a couple hours later and they, too, were very polite and professional - discussing everything with me before they started touching anything. There was some additional work that had to be done because of the allignment of my exhaust piping - but they all stayed there for the rest of the day - making sure the system was installed that very same day as promised.
My wife and I couldn't be happier with the quality of their customer service, installation, and products. The entire team has been lovely.
Thank you!





Great communication.
Explained everything in detail.
Took before and after pictures.










Professional honest and reliable… couldn’t have gone any better,replaced two ac units and blown in insulation with great workmanship and very friendly fast service starting with my initial phone call throughout the whole operation all in less than 24 hours. They’re amazing.
They delivered on everything and that’s hard to find anywhere.
5 stars from me.


I’m very glad he checked our system.









20 MAY 2023....our new AC unit wasnt working as well as we hoped....we called Goettl and they got a tech out in 3 days....Matt showed up and trouble shooted the problem....within an hour nice cool air!!! Thanks everyone for your prompt service and customer relations!!!!
24 January 2024.....tech Camren White came out as first part of our double inspection ....he was the plumbing part...professional and friendly. Very knowledgable....installed sensors and explained a lot for us. Another example of the top notch customer service you provide
6 March 2024 tech Matt Wilburn came out and inspected our heater system.....he was thorough and explained what he was doing. Matt was courteous, friendly and even brought my wife the stuffed animal dog which she loves! I cant say enough good things about Goettl ....very pleased
7 October 2025...tech Andrew Juan came out for a plumbing problem. Came up with a solution quickly and efficiently. He explained everything and was helpful. Once again Goettl did as advertised. Highly recommend thus company because they stand by their customer service.









He even went as far as calling Lennox to ask about our warranty on the unit. I am very pleased with attention to detail from Jonathan.
Great guy. Great job.




I called Goettl and set up an appointment.
Mike H arrived on time and with his extreme knowledge and experience, he was able to replace the tank and give my system a much needed flush. Mike was so courteous and polite and answered all my questions and gave me advice on the how and why this happened and how to avoid this in the future.
Thank you Goettl and thank you Mike!

Adam was also very good with our situation. When there was a hang up with the loan company, not due to us or Goettl, he quickly found another to accommodate. He went above and beyond. Thx for making our home cool again.










system.and aqua Flo system. Amazing guys who made sure the installation was done right.







Update: I accepted your proposal and wow, three days later my house has heat and air. Installation time was a little over five hours with breaks, and all the time your crew worked efficiently and professionally. Nothing left undone. A big THANK YOU for you guys.
Update2: Goetti set up the building permit appointment with the county, and attended the inspection, which past with no issues. Other companies that I have dealt with have not done so much. Furthermore, I did get multiple estimates, and all the other companies had convenient add-on's which proved by the inspection were a unnecessary expense, thus making Geotti price the lowest and most honest of them all. By the way, the heater and a/c have work to perfection and are both very quiet


This past week our service technician was Andrew Morgan and he is such a friendly, knowledgeable, and skilled technician. He spent time making sure the job was done correctly and he explained it in terms that I could understand. Not only is our unit functioning even better than before, I also gained knowledge of how the system works.

















I highly recommend Goettl as this is the second time l've used them in less than a year. (2 seperate issues)... and I highly recommend them..anytime and anyday.
They have exceeded to top any expectations I could have ever had with any company.


Jerry also noticed our water pressure was low after flushing toilet then trying to wash hands in bathroom sink which were so he suggested a new pressure regulator as we have had a new better water conditioning system installed. We now have the best water pressure even when using a shower and kitchen sink faucet at the same time. Also Jerry is a master plumber and we appreciate his knowledge and experience. Will definitely call Goettl again when a plumber is needed.
Ralph & Kathy Lesmeister



Darean Guerra today. He arrived on time and took the time to explain what he was going to do. He was very knowledgeable which helped me trust what he was doing. He left his work area clean. I am very pleased with his work.




Now we have a new flange, installed correctly, and ready for the new toilet!








The company is installing a tankless heater and the customer service is outstanding.
I recommend Geottl to all!

I definitely recommend Goettl for all your needs.

Nick was helpful, friendly and professional in scheduling the appointment around my commitments.
I have used Goettl for nearly 20 years for my plumbing and HVAC needs. I recommend them as reliable, professional and easy to work with.



They made sure my carpet was covered and when they were all through they cleaned up perfectly
I would recommend your company to anyone looking to put in a new air conditioner.
Thank you so much for all you did for me.
Sincerely, June Jones

And I would highly recommend the company and the quality technicians like Jarod.
Jarod is the go to if you want excellent
Customer service and communication for any AC related issues. He is very knowledgeable, personable and trustworthy. I am grateful and satisfied.







They listened to my issue, were very through, checked for leaks, etc. I’ve lived in Lakeway for 30 years, used MANY local plumbers - but Goettl will definitely get all my business moving forward. HIGHLY recommend!
Ty, Wil & Adrian!

Everyone from the Goettl sales representative Christian, Tech / Advisor Josias recommended a HVAC A/C and Heating system replacement. Technicians team Veronica and her partner.


Jeremy Canchola serviced our mini-split today with the usual Goettl efficiency and professionalism.
Highly recommended!


Hopefully, we will get Jack for our next service call.







Robert, Tyler, Adrian & Luis, Thank you all so much.
