AC FAQ: Why Change the Air Filter?
Pop quiz time — what is the single best thing that you can do to keep your air conditioning system in great working condition? If you answered “schedule routine air conditioning maintenance,” then you are correct. Mostly, anyway. Yes, scheduling routine air conditioning maintenance in North Las Vegas, NV is absolutely vital in the quest for a truly great home cooling experience. That being said, you’d be overlooking a very important step if you thought that this was all that is required of you.
While the bulk of your air conditioning maintenance procedures must be completed by trained professionals, there is one specific task that you yourself should be completing regularly. That is changing your air filter as needed. Typically, this means doing so every 1-3 months — though many factors will influence the situation and regularity in your home. If you have any doubts about just how important changing your air filter really is, we hope that you’ll keep the following information in mind.
How Big of a Difference Can It Really Make?
We get it. You’ve got a lot on your plate, and the fact of the matter is that changing your air filter just doesn’t sound like that big of a priority. After all, it isn’t like your air conditioner is broken down or anything, right? Well, we really need to stress the fact that, simple a step as it may be, changing your air filter really can have some pretty major benefits for you and your system — just as failing to change that air filter can have some pretty serious consequences.
- Enjoy better efficiency. It goes without saying that we run our air conditioners a lot in this part of the country. You are going to have to pay for your comfort when the heat of summer strikes, but you should not have to overpay. If you leave a dirty filter in your air conditioner, though, chances are that you are going to be doing just that. Increased airflow resistance will force the system to work harder than it should have to in cooling your home, and your energy bills will reflect that.
- Enjoy better comfort. When your air conditioner is struggling just to force cooled air throughout your home, it is not going to function at peak performance levels. That will leave your comfort to suffer. The areas furthest from the air handler may not cool down as much as those closer, and your air quality may drop off as well. Very clogged filters can create so much airflow resistance that it is easier to force air around the filter than through it.
- Enjoy better reliability. Your air conditioner should go through a full cooling cycle before shutting down. If your air conditioner has a very dirty air filter causing it to overheat, though, then your system is likely going to wind up short cycling. That means that it will start up, run only briefly, and then shut back down. This increased strain can compromise the system, and increase the risk of damages.

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!

Went into detail explaining to me what was causing the A/C Thermostat to turn off. He was very professionalc and ourteous.
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

Call Goettl and was able to get us on the schedule due to a cancellation they had.
Jef Eusepi our tech was fantastic.
He explained everything and showed us pictures of what he was doing and fixing.
Would definitely recommend this Company and Jef.















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.


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







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.
