What Does Ice on an Air Conditioner Mean?
In certain parts of the country, there is still snow on the ground (or even in the forecast!). In other parts of the country, signs of warmer weather are becoming more apparent, though the real hot temperatures are still a ways off. Here in Arizona, though, we’re already seeing temperatures in the upper 70’s, or even the mid to high 80’s!. Our air conditioning systems often get a much earlier start than those in other areas, which is exactly why it is so important that you have yours tuned up and ready for action sooner rather than later.
Now, routine air conditioning maintenance is definitely the best way to keep your AC up and running properly. The truth of the matter, though, is that even the best air conditioners that are the most diligently maintained are not going to function 100% reliably. No mechanical system will. The best thing to do is to learn the warning signs of problems, so that you can schedule prompt air conditioning repairs. One issue that you may encounter is ice building up on your system.
Ice on the Evaporator Coil
You may not have much cause for checking in on your evaporator coil. However, it is actually very beneficial to do so every now and then. You may not feel comfortable cleaning your evaporator coil on your own — which is something that we are happy to do for you — but peeking into that air handler from time to time means that you can catch signs of icing over early on.
Your evaporator coil is the point at which refrigerant is evaporated, hence the name. The evaporation of your refrigerant allows for the removal of heat from the air within your home. If there is ice on your evaporator coil, then it will impede this process, causing your system to overwork itself in trying to cool your home. That is why it’s a problem — but what causes the icing?
If it is your evaporator coil that’s iced over, it could be something as simple as a dirty air filter. You could also have blower fan problems. How does this cause icing? By restricting airflow. If there is not enough hot air moving over the evaporator coil, then the coil can get too cold. When that happens, the condensation that collects 0n the coil before being drained down the condensate drain/pan assembly can freeze over. The thicker the ice gets, the more insulated the coil, so this is something of a self-perpetuating problem.
BONUS PRO-TIP!
Air conditioners do not use water in their operation (other than swamp coolers, which don’t use a refrigerant cycle). If you have a central AC or heat pump, and see water surrounding your indoor unit, it could be ice melting off of your evaporator coil.
Ice on the Condenser Unit/Refrigerant Lines
If you have ice on your outdoor unit, you’d probably be surprised considering just how hot the air outside is. Obviously, this is an abnormality. Ice on the outdoor unit, along with frost or ice on the refrigerant line themselves, will generally indicate a refrigerant leak. Basically, having too little refrigerant in the system is going to lead to issues with the heat transfer process, which can cause this icing. You may also have a refrigerant leak if your evaporator coil is iced over, though it’s not as immediately obvious and would likely be accompanied by these other points icing over.
Allowing your system to run when it’s icing over can lead to serious strain on your AC, particularly on your compressor. With weather as hot as ours, that is just inviting catastrophe to your system. Don’t let your system overheat and burn out. Contact our Phoenix office to have the problem resolved immediately.

What Our Customers Say About Us






A BIG THUMBS UP!!!!!👍

The estimate for the duct cleaning was presented transparently, with clear explanations of the process and pricing, making it easy to understand. Highly recommend.








We had 2 split units serviced. The tech serviced both inits with a thorough checkup in 3 hours. Very good attitude throughout.


I called so many companies before this, and no one took the time, care, or patience that Josue did. His customer service was outstanding, his knowledge was impressive, and he genuinely cared about making sure I got the right solution, not just a sale. I was honestly surprised by how detailed and honest he was.
If you want things done the right way, I 100% recommend Goettl and especially Josue to have in your home. Truly top-notch service!

My issue is that service was for the morning and ended up at 3pm. This has been a problem for multiple service/maintenance appointments to include two cancelations. As a working professional, timing is very critical in my daily scheduling.

We discussed options and agreed that a detailed lcleaning and sewing of all the ducts should eliminate this problem. He discussed financing and, and returned the following morning to make all the arrangements. He also advised us not to continuously run the A/C fans when the unit was not cooling, which seems to have helped with the humidity already, even though the duct work isn’t scheduled for a few days hence.
It was a pleasure to work with a knowledgeable A/C technician who could quickly isolate the cause of our problem and arrange a solution.

Kudos to Frank Soto 👏

Goettl provides fast and professional air conditioning repair services. Their technician sam was knowledgeable, prompt, and efficient, ensuring that systems are back up and running quickly. The customer service is friendly, and they offer clear communication throughout the process. Highly recommended for quality HVAC repairs.














Will recommend again
Ralph, had issue with the water heater. Called at 9:30 and they were out here at 11:00. Checked everything and is working now. Great service



Julian and his team (Joey, Jeran, and Alonso) are extremely knowledgeable, efficient, and worked hard to get us back up and running as quickly as possible. Upon completion they send a detailed email with pictures.








Thank you!


Update: 1/7
Stacy excellent service excellent job well done professional communication excellent explain everything on the up to date stuff I need to do in the future appreciate your service have a nice day thank you


Update:7/21/23
Mel and Justin showed up to install my ac unit. They worked non stop through the heat, answered all of my questions, and were so courteous. If I could give 6 stars I would!! Thank you Goettl!

2 thumbs up 👍🏽 👍🏽










Thank you!



There has also been times when they schedule an appointment days in advance, then they'll call you at that last hour to tell you that they have to order a part. But keep in mind that they've had days to do so prior your scheduled appointment.
I really had high hopes.....sigh.
Matthew, Brian, and Christian are all impeccable. Matthew came and found issues that was missed by another company that we actually had a contract with. Long story short, Goettl now has our loyalty. Their service was just that great. They spotted issues that were missed, their service was spectacular, and their mannerism was amazing. I had our whole system replaced at a great rate. Brian and Christian were here alllllll day, literally. I'm sure they're supposed to have lunch breaks but chose to work non-stop. I literally had to get them to take a 2 minute break just so they can eat lunch, which I gladly provided for these hard workers. Thank you Goettl for fixing our issues.
Must I not forget to mention, they'll even call to set up complimentary maintenance checks which is amazing. Rudy had came out to do my annual maintenance check and he was so great and so friendly. He checked my unit, my thermostat, flushed my unit, and checked the outside unit making sure everything was running correctly. Thank you Rudy for doing a great job.






Update 01/05/26 Stacy was here to evaluate duct system clean and did a fabulous job and helped with dryer vent cleaning and other questions!


This January's visit with Kevin

I am very satisfied with my Goettle services, their employees, including the scheduling staff, and highly recommend this company.

Knowledge and experience work hand-in -hand. He is definitely a KEEPER for your business!!!




From the moment, Chris introduced himself he was courteous, polite, and dressed professionally. He patiently listened to my plumbing issues and then went to work to resolve them when complete he asked me to check everything out to make sure it was to my liking. Chris is a very competent plumber. Thank you, Chris


We have known our water heater was at the end of its life. Goettl came in to do maintenance. Brent S. was our technician. He was very kind and knowledgeable. He explained the different options and we ultimately decided to replace our water heater with his help.
We were able to get it replaced same day. The crew who replaced it Zach C. (and I think Darrius?) did a great job replacing the water heater. Happy with everything!
Was having AC issues and a technician was able to come out the same day we called. Chris Rios did a great job showing and explaining in detail the problems we were experiencing with our unit. In the end, it was best for us to replace the entire unit. A crew was actually able to come out the next day to install the new unit. Juan and Carlos did the installation and did a great job! They were on time and were thorough. Happy with the entire process!









Goettl plumbing supervisor, Craig Cooper, arrived to survey the problem. Craig determined the valve had been incorrectly installed during the previous water system installation. Craig immediately contacted water mitigation supsrvisor, Ethan Gray at Quick Restore LLC.
Craig coordinated with Ethan the construction, drying of walls/carpet and services for the boxing and storage of our personal property. The reconstruction and repair work was done professionally and in an outstanding time frame for me to undergo major spinal surgery.
I wish to thank Craig for his outstanding integtity and attention to detail for this undertaking. He arranged for Goettl to cover all the costs involved for the work, boxing, moving, storage and water mitigation.
We are so very grateful to Goettl for their wonderful work ethic, technicians and supervisors. We absolutely continue to use and wholeheartedly endorse Goettl for all our AC and plumbing services! Thank, you again Craig!



12/31/24 Jasmine did an extremely professional job inspecting everything in my home for leaks, and informing me of all potential issues that might occur. What a wonderful and intelligent young person. All the people at Goettle are so friendly.
8/28/25 Alberto Martinez is very professional and extremely friendly. He cleaned my air-conditioner, changed my air filters, and set up my sensors in record time! He answered all my questions and made me feel confident with my new equipment. I HIGHLY recommend Mr. Martinez and the great people at Goettl.
Alberto Escobedo Quinones is a true artist! He made the hole in my ceiling from my HVAC install disappear! It actually looks better than it did the day I bought my Home new 30 years ago. Very professional and extremely friendly.




Update 12/31:
Stacy and Chris were excellent! They listened to my concerns and answered my questions about my system. Both were professional and represented Goettl with expertise. The commercial says “we do things the right way not the easy way “ was evident in their approach to the service call and the way they handled the maintenance of our system. Thank you so much!





Parker was very pleasant, knowledgeable and respectful of us and our home.
You’ll be in good hands with Parker and Goettl







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.
Follow up: A home inspection showed a small issue with my new furnace, so I called Goettl. Next day service and they determined there was an issue with the furnace they installed. Two days later (Christmas Eve) a brand-new furnace was installed. No debate, new questions asked, no cost to me, they insisted. This was quit the contrast to what I experience with other HVAC companies I have dealt with in my forty years in Reno.





Highly recommend Goettl Air Conditioning and Plumbing!!!





Pipes, all under the house with low clearances. Alan and partners did a very professional and considerate work. I'd recommend them to anyone.



A short history. A few years ago, we had four seasons put in a new furnace. After checking around and getting tons of estimates, there was as much as a $10,000 difference between all of the estimates. Four seasons came in at the best price. Unfortunately, I ordered an 80,000 BTU furnace and when the guy was done, I looked at the furnace and saw that it was a 60,000 BTU. I showed the guy the invoice and basically his response was ‘ Oh crap’ so I talk to the manager and he assured me that 60,000 BTU would heat my home sufficiently since it was a high-efficiency unit.
I was ready to have them tear it out and put the right one in, when the manager guaranteed the furnace and gave me the price for the 60 KBTU with a substantial discount. I did the regular maintenance and service service with four seasons.
When Goettl took over, I’m not sure if they just change the name, or bought four seasons, but everything changed after that. First I was informed of a membership called Sadie which is basically a yearly/monthly fee that allows us to get a lot of benefits. Free service calls, free, free preventative maintenance and discounts on non-covered items.
The first thing that I noticed was Josh came in to do a service, check the pressure and saw that the original installation guy did not convert my furnace to propane. Apparently none of the other service people ever checked the pressure. He had to return with the correct parts and changed out the valve. He also helped me out with a bathroom heating duct that was ripped. The price was great and he said he felt bad that we had such issues with the previous company.
A few months later (last Saturday) we stopped getting heat. I called Goettl let them know, and they were at my house within two hours. When it’s freezing outside or going to be subzero it’s really important when they respond so quickly.
Chris was the technician and he found the problem, however, the plumbing supply company was not open till Monday morning. Two days with sub, freezing temperatures scaring me a bit. Chris said that he would check with Dispatch and see if they had a couple of space heaters. When he was leaving, he noticed we had a bunch of firewood on the front and he offered to help bring firewood in. I told him no problem we had it, he said he was happy to help us. Make sure we had enough firewood to get through two days.
These two offers, were above and beyond in something you really wouldn’t expect from your HVAC people. Unfortunately, they didn’t have any space heaters at Dispatch, so we went to Home Depot and got some radiator heaters and then yes 24 hours a day kept a fire going.
Chris showed up Monday about 11 AM with the parts and it took him about 2 1/2 to 3 hours to fix all of the problems. I’m not savvy with all of the HVAC terms, but something about condensate water bill backed up through the system blah blah blah… we now have heat. lol.
Getting the Sadie member membership/club was the best thing we decided to do. They call us regularly to schedule our summer and winter maintenance. They are responsive. And they are very polite every time I call them.
I really would recommend you contacting them and get on that membership before you actually need them. Thank you, Josh and chris and unfortunately, I cannot remember the name of the female technician that came out and changed our filters but she was awesome also!

Like most people, I typically search for the cheapest service I can find, and I end up having other plumbers come out to check out issues with my tankless water heater, who run their mouths, upsell parts (that don't seem to be causing the problem), and generally don't really know enough about tankless water heaters. This time, I decided to go with an experienced company with a good reputation, and I am glad that I did - Goettl's prices are very reasonable and worth the service they provide.
Juan, was very knowledgeable, patient, and persistent. Even better, he was careful and humble enough to acknowledge that he didn't know everything and checked with the manufacturer at every step. Juan spent a great deal of time helping me diagnose the problem (which always seems impossible to ascertain quickly with machines like tankless water heaters), and went above and beyond to ensure that my guests and I had hot water tonight.
Juan never got frustrated; he handled everything carefully and made sure to clean up after himself when he was done. If I can have Juan take care of all of my plumbing or AC issues in the future, I will. And if you're reading reviews to decide whether to call Goettl for your issue, I would encourage you to trust their service and experience. My experience with Juan was definitely memorable.
We now have hot water again. Can I get a "hell yeah"?


We had a concerning plumbing issue, and Geo was able to diagnose the problem with impressive speed and accuracy. What I really appreciated was that he took the time to clearly explain what was wrong, showed me what he was looking at, and gave me honest, practical advice on the best solution.
He had the issue resolved in no time at all. The whole experience was seamless, from the quick scheduling to the efficient and high-quality work. It’s so refreshing to find a technician who is not only a master of his craft but also a genuinely kind and trustworthy person.
A huge thank you to Geo and the entire team at Goettl. You have a customer for life! If you need a plumber, ask for Geo—you’ll be in the best hands






I have seen Goettl vans all over town and so I called them.
Got appointment right away and the Technician, Jef Eusepi, took care of our problem.









Thank you,
Greg Sanches





















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.







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


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!
