What Does El Niño Mean for Your HVAC System in Phoenix?
El Niño (technically termed “The El Niño Southern Oscillation” or ENSO) is a condition that occurs off the Western Coast of South America when the sea surface temperature is warmer than normal. In turn, this triggers unusual changes in climate that can affect parts of the Western Pacific United States. The variations can lead to higher precipitation in some regions, and drier climates in others. For 2014, the current predictions for El Niño through to January is that it will be weaker than usual, and the Climate Prediction Center (CPC) has cautioned that there is “reduced confidence that El Niño will fully materialize in at least five overlapping consecutive 3-month values.”
What does this mean for us in the Valley? Generally, during El Niño we would experience a wetter and cooler winter season. Historical tracking of precipitation during El Niño across central Arizona over a hundred-year period shows an average increase in rain fall of 143% compared to non-El Niño years. Although the current predictions for the season lean toward a weaker El Niño—or possibly none at all—we may still experience a large increase in rain fall in the Valley, rising from 2.71 inches for the winter to 4.81 inches, with generally cooler conditions than usual. We at Goettl Good Guys Air Conditioning want to make sure you are prepared for any event and can keep your house warm through the season.
It’s important that you have maintenance done for your heating system before the winter weather arrives, especially considering the unpredictable conditions and the chance of long rainy stretches due to El Niño. Heating systems in Phoenix, AZ need complete inspections and tune-ups this season more than ever. If you use a heat pump for warmth—as many Phoenix homes do—it is crucial to make sure that the outdoor unit of the system is weatherproofed in case of extended periods of rain that might damage it.
Another reason to call for HVAC technicians to inspect your heating is to see that the ventilation system doesn’t have any obstructions and its filters are clear. An increase in moisture brings with it a danger of mold infestations in your ductwork, which you want to stop as soon as possible or else it will affect your indoor air quality.
To help prepare heating systems in Phoenix, AZ to keep homes warm, Goettl Good Guys Air Conditioning offers quality maintenance and inspections services.
Our heating tune-up will make sure that your home’s HVAC system is ready to weather whatever El Niño can send our way. Call us today!

Andrew diagnosed the repair and resolved all of my sink/faucet/plumbing issues at a reasonable cost. It is always a breath of fresh air to work with fair and honest Plumbers/technicians. Thanks again, we appreciate it.


I especially want to give a shout out to Connor, who did the replacement, he was awesome. He was respectful and cleaned up afterwards. I even commented on how impressed I was that he was able to fit everything needed in a small space.
Overall I would recommend Goettl services especially in an inconvenient situation like mine. They will make you a priority.


Update-9/26/2025-Angel Zamora, Jose Torres, and Jonathan Saucedo are great assets to your team. You couldn't ask for better representatives for your brand. They were efficient and got the job done right. I really appreciate them.
Alex Nelson is the BEST! When I say I thought I was going to die from this extreme heat and Alex came along and saved the day, he did! Im so thankful he is honest and trustworthy! Thanks Goettl!!





Zack and his crew who did the tile work, made it look easy! We can't wait to try it out after the caulking and other stuff set up and dry out!


This appointment was to check that my heater is working properly before winter arrives.





Today the HVAC team came with a coil cleaning and suggested maintenance. Steven and Jonathon were top notch. Courteous, professional and informative. If you want it done right, get Goettl.

Maintenance, I have 3 (three) units, Brandon
Completed the work in a reasonable amount of time, and gave a comprehensive overview
Of conditions , He was very courteous, with good appearance , and was careful of surrounding furniture.
I would rate him, Excellent.




















Given the extent of the work I need to get multiple quotes and some companies insist on expensive trip charges (one up to $500) to have a “specialist” assess before providing a quote for the work.
These guys were timely, transparent and uncomplicated. I appreciate Shane for quickly putting together an estimate before even leaving the house, providing multiple options at various price point and without pressure of upfront commitment.
I would feel confident moving forward with these guys. Thank you Shane!

Stacy arrived today. He was super knowledgeable and interested in answering our questions (which were abundant). Very friendly and not in any hurry to leave. He took his time to explain what he was doing. He pointed out a dangerous situation with our surge protectors. We had fried wires! We ended up having them replaced right on the spot. We were so impressed with him that we will be requesting him next time we're due for our routine check up. Thank you,
Stacy!

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!


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.
