Dirty Air Filters Cause Heating Problems
Heaters are mechanical systems, and that means that occasional operating problems are inevitable. Routine heating maintenance will certainly help to keep any such problems to a minimum, but you are eventually going to require professional heating repairs in Phoenix, AZ. The fact that our winter season is so mild does not mean that you can just ignore problems with your home heating system. While annual maintenance is a must, there is also one maintenance task that you should handle on your own, much more frequently than once a year.
That task? Changing your air filter. If you use a forced-air heater, such as a furnace or a heat pump, then you need to make sure you are keeping a fresh filter in that system at all times. Typically, it will need to be changed somewhere in the range of every 1-3 months. These filters are cheap and very simple to swap out, and the benefits of doing so as needed cannot be overlooked.
Dirty Filter? What’s the Big Deal?
We know, we know. The heater is still heating, so a dirty filter can’t be that big of a deal, right? Wrong! Sure, your heater may still be up and running. That does not necessarily mean that it is up and running properly, though. It also doesn’t mean that the strain put on it by that dirty filter is not taking its toll on the system.
The major issue with a very dirty air filter is that it creates a lot of airflow resistance that the heater must overcome in order to distribute heated air throughout the house. This higher level of resistance means that the heater is going to be using more energy than it should in order to effectively heat your home, and that means that you are going to be paying more money to heat your home than you should have to. Not only that, but you are probably going to be paying more for what amounts to a weaker heating performance.
This drop in energy efficiency is troubling enough, but that is hardly where the problems caused by dirty filters end. You see, that strain put on the system by the dirty filter also puts a lot of wear and tear on the system. That causes parts of the system to degrade, and that increases the risk of running into repair needs with increased frequency.
If enough resistance is created due to this dirty filter, the system can actually start to overheat as it struggles to do its job. That can result in short cycling, wherein the system shuts down before a full heating cycle is completed in order to avoid damages. Short cycling wastes a lot of energy, and the starting and stopping of the system over and over again increases the risk of damages.
With all of this in mind, it should be clear that the benefits of a fresh air filter are well worth the minimal expense and effort of purchasing and installing replacement air filters. Please feel free to contact Goettl Air Conditioning Phoenix with any questions that you may have.
G-O-E-T-T-L it’ll keep you cool but it’s hard to spell.

A special shout-out goes to Pablo, our technician. He was on time, friendly, and extremely knowledgeable.

Initial review 2/2025:
Jorge "George" was respectful and easy to communicate with. He listened and answered all our questions. Informed us of what and how Goettl could do with the 20+yr old system in our home, and gave us time and space make the best decision for us. So far very pleased with Goettl's professional conduct and standards.







Gilbert Castaneda was our technician today for A/C maintenance. He was informative with all my questions, did his job in a timely manner and a very pleasant young man to work with.


Really a 5 star on original review.









On time, clean, and very thorough with any potential issues.
Thank you.



Thank you Jesus!

Tyler Leija came to my home and flushed out my two water heater’s. This had never been done to the home since it was purchased in 2017. Let me tell you the stuff that came out of the water heater’s was an eye opener! It was filled with so much calcium deposits. Tyler was very knowledgeable and explained everything going on. Thank you Tyler for coming to our home and flushing out our water heaters.











Chris R came out for our Sadie Membership inspection and review before the cold comes here in TX. He did a fantastic job and really knows his stuff. Thank You!


As always great experience with Goettl services and staff. Thank you!

















Mike provided truly exceptional service. From the moment he arrived, it was clear he was extremely knowledgeable; he quickly and confidently diagnosed a very tricky issue that we had with our pipes, explaining everything clearly and answering all of our questions with patience. He also installed our new water heater and did an outstanding job. If you need a plumber who gets the job done right the first time, we highly recommend Mike. Thank you!








The Goettl team has been very professional and helpful to me as their customer. Thank you, Kelli Stoika.
PS… If there would’ve been 6 stars on the scale, that’s what I believe they should’ve received.

UPDATE Julian and his team, Nick & Jeffery, were here to fix my sewer pipe. They explained everything thoroughly and kept me apprised of their progress. When they finished, it looked as if they hadn’t been here even though they dug a giant whole in my yard! Most impressive! I highly recommend Goettl.
UPDATE November 14, 2025
Goettl continues to be a 5-star company for me. Always, on time, clear explanations, fair pricing, respectful of property and competent, friendly staff. Caelin was my team member today and upheld all of these values.


Jason and Marco operated like a well oiled machine with one replacing the AC unit while the other replaced the furnace. Clean up was excellent and the system works beautifully now.

I will definitely use their services going forward.
Thank you Goettl Air crew!

Greg Sanches

Thank you Jef, for helping me keep my home cozy and safe.


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.





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.
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.


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