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






Tai Fernandez-Estabillo, service rep is excellent. I deal with a lot of contractors in my student housing operation and he is at the top of his field. Proud to know him. Thanks for the professional service Tai.



Husam, Raymond, Johnny, Joe, Marcus; Very professional and great communication skills. Great service all around!





Mike was so very thorough and explained each thing that he was taking care of, that I asked him if I could request him for our next service.
I wasn’t sure if I was going to renew my membership with GOETTL, but after such a great experience with Mike, I’m definitely renewing..





Daniel came out to perform my yearly maintenance review he did a great job. He was very informative. Provided recommendations and very knowledgeable. Very polite and professional. I would recommend him for services






Goettl is not cheap, although their service visit is very inexpensive, their quotes are almost always considerably higher. The service from an employee like Gilbert, however, is the sole reason why I would even consider entertaining a higher cost.

you Goettl!













William came out for warranty work in September and quickly got our issue diagnosed and up and working again. It's always scary when your AC goes out in Texas, so I appreciate the effort to get the work done and resolved quickly.


Recommend Highly!

He certainly understands what Customer Service is all about!
Joey was on time, well-mannered, and very professional. He took care of our problem, took time to explain all aspects of the project in detail, and left the work area nice and clean.
We will definitely utilize Goettl’s services in the future, as needed and have nothing but the highest praise for Joey Martin!










I would recommend him.


Update: December 2025: Kaelyn Nuss did a great job with our annual plumbing service!

Thank you Kevin... Blessings

Explained everything clearly and was very respectful..
Thanks for a job well done Frank.


















As usual we are very satisfied with Goettl















I had such a good experience with Goettl the last time, that I decided to use them again for HVAC. Kevin was the technician assigned to my job. He was very professional and provided me with a thorough and accurate diagnosis. He patiently explained everything to me and walked me through the recommended repairs and even shared alternative solutions. I have the information I need and feel comfortable moving forward. I’m in good hands. I will be requesting him as my technician for all future calls.

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

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.


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.

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!
