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.

Mike was absolutely Top Notch!! He arrived at 9:00 pm in a great mood, then took care of business and left in a great mood..Two thumbs up!!

Also, we are apart of the Smart Sadie Program and just received our yearly plumbing rejuvenation and we had the pleasure of meeting our Tech, “Frank M”. He was so knowledgeable and taught me and my Husband so many things we didn’t know which we value so much as we are new home owners and are just kind of wingin’ it! You can really tell that the Techs and the company genuinely cares about their Clients, and I will be requesting Frank M to service the Plumbing needs within my home from this point on! Frank is the man, and we loved him!(:
So now we have Christian and Daniel for our HVAC maintenance and servicing and Frank M for all our Plumbing Needs! We have an amazing team and I’m sure that other Clients feel the same way about their Techs as well!
Love this Company!


We’ve been Goettl customers for years and have always appreciated their service, but Kevin Edwards truly raised the bar. During his visit yesterday, Kevin showed outstanding attention to detail and technical expertise. He thoroughly inspected every part of our HVAC system, documenting his findings with photos and clearly explaining issues that had gone unnoticed through several previous service visits.
Kevin discovered that our HVAC system had been improperly installed when the home was built—something no other technician had identified. He explained how that flaw had created a chain of problems affecting the furnace, cooling system, and overall efficiency. Because the system uses an outdated refrigerant, repairs weren’t a viable long-term solution, and Kevin guided us toward a responsible upgrade plan.
While no homeowner wants to replace a system after only seven years, we’re grateful Kevin uncovered these hidden issues before they caused a catastrophic failure. His thoroughness, honesty, and professionalism turned a potential headache into peace of mind. Kevin is an exceptional representative of Goettl, and we recommend him without hesitation.

I want to express my complete satisfaction with the work performed by Frank Piusseaux, a technician from Goettl.
For months, several technicians tried to identify the issue with my air conditioning unit, but no one could solve it. However, from the moment Frank arrived, he showed great professionalism and dedication. He took the time to carefully investigate the cause of the problem and determined that the issue was a short circuit in the wiring between the thermostat and the unit.
Thanks to his knowledge and effort, my air conditioning system is now working perfectly.
I truly hope that Goettl recognizes the value of having such a skilled, responsible, and committed employee. Technicians like him make a real difference and deserve special recognition, even a financial incentive, for the value they bring to the company.
Thank you very much, Frank, for your excellent work!





Team Nacho and Brayan installed a 4 ton unit, very professional, very courteous, explained operation as well as answered our questions. Nacho and Brayon cleaned up as if they weren't here. We would certainly utilize their services again.







David and Cesar worked on my water heater and they were all amazing. Great prices and work with me! Will be going to them in the future

ellent job ..5star work. Thanks
Corey 4,17,2025 Master of flow 6 star toilet fixer plus. Thanks
10/9/25 Daniel great service very friendly and knowledgeable. Furnace Thanks

To my surprise, the rep came out within a hour or so - that same morning. He educated me on a few tips - like not needing to shut off the water to the entire house in a situation like this - and a few other tips, but as for the water heater - it was toast and already beyond the warranty it had.
There was zero sales pressure for a specific water heater - and instead, he spent quite a bit of time with my wife and I going over the many different options they had for replacing one.
Once again to my surprise, after we picked one - he was already on the phone with a crew and the installation was set for that same day - no extra charges for an emergency situation or anything like that. The crew came out a couple hours later and they, too, were very polite and professional - discussing everything with me before they started touching anything. There was some additional work that had to be done because of the allignment of my exhaust piping - but they all stayed there for the rest of the day - making sure the system was installed that very same day as promised.
My wife and I couldn't be happier with the quality of their customer service, installation, and products. The entire team has been lovely.
Thank you!





Great communication.
Explained everything in detail.
Took before and after pictures.










Professional honest and reliable… couldn’t have gone any better,replaced two ac units and blown in insulation with great workmanship and very friendly fast service starting with my initial phone call throughout the whole operation all in less than 24 hours. They’re amazing.
They delivered on everything and that’s hard to find anywhere.
5 stars from me.



I’m very glad he checked our system.













20 MAY 2023....our new AC unit wasnt working as well as we hoped....we called Goettl and they got a tech out in 3 days....Matt showed up and trouble shooted the problem....within an hour nice cool air!!! Thanks everyone for your prompt service and customer relations!!!!
24 January 2024.....tech Camren White came out as first part of our double inspection ....he was the plumbing part...professional and friendly. Very knowledgable....installed sensors and explained a lot for us. Another example of the top notch customer service you provide
6 March 2024 tech Matt Wilburn came out and inspected our heater system.....he was thorough and explained what he was doing. Matt was courteous, friendly and even brought my wife the stuffed animal dog which she loves! I cant say enough good things about Goettl ....very pleased
7 October 2025...tech Andrew Juan came out for a plumbing problem. Came up with a solution quickly and efficiently. He explained everything and was helpful. Once again Goettl did as advertised. Highly recommend thus company because they stand by their customer service.









He even went as far as calling Lennox to ask about our warranty on the unit. I am very pleased with attention to detail from Jonathan.
Great guy. Great job.





I called Goettl and set up an appointment.
Mike H arrived on time and with his extreme knowledge and experience, he was able to replace the tank and give my system a much needed flush. Mike was so courteous and polite and answered all my questions and gave me advice on the how and why this happened and how to avoid this in the future.
Thank you Goettl and thank you Mike!

Adam was also very good with our situation. When there was a hang up with the loan company, not due to us or Goettl, he quickly found another to accommodate. He went above and beyond. Thx for making our home cool again.
















system.and aqua Flo system. Amazing guys who made sure the installation was done right.







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


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.










He was very professional getting the furnace in . He made sure the new filter was put in well and secured it so it looks very neat, as opposed to the old one-- really large, obtrusive, and screws falling out, but too high for us to correct.
Thank you, Goettle group.








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.

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!

I definitely recommend Goettl for all your needs.

Nick was helpful, friendly and professional in scheduling the appointment around my commitments.
I have used Goettl for nearly 20 years for my plumbing and HVAC needs. I recommend them as reliable, professional and easy to work with.



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.

Highly recommended!


Hopefully, we will get Jack for our next service call.
