AC Repair Warning Signs: Strange Sounds
Living comfortably in hot areas heavily relies on your air conditioning system. Given the consistently high temperatures for much of the year, your AC will be working hard. So, it’s crucial to take every possible measure to ensure your system operates smoothly and reliably. It includes addressing any issues with your air conditioner as soon as you notice them.
While encountering a malfunctioning air conditioner is always unfortunate, the silver lining is that there are typically warning signs that indicate your system is struggling. One of the most common indicators is unusual operating noises. If your air conditioner suddenly starts making unfamiliar sounds, don’t dismiss it as insignificant. It could indicate a sign that your AC needs immediate repairs. Here are the signs to watch out for.
Identifying Strange AC Sounds
New or Loud Sounds Indicate a Problem
A common mistake many homeowners make is assuming that if their air conditioner runs, it must run properly. It is only sometimes the case. Many issues can persist for a long time before the system breaks down. Ignoring unusual sounds while your system is still functioning will only allow existing problems to cause more extensive damage.
Strange noises are often the first sign that something is amiss with your air conditioner. For example, a grinding noise could indicate a problem with the motor bearings, while a hissing sound might point to a refrigerant leak.
If not addressed promptly, these issues can lead to significant damage and potentially costly repairs. By paying attention to and investigating unusual sounds, you can catch problems early and avoid more extensive damage to your system.
Furthermore, consistent maintenance and early intervention can significantly extend the lifespan of your air conditioning unit. Addressing issues as soon as they arise keeps your AC running smoothly and ensures it operates at peak efficiency, saving you money on energy bills. Taking strange AC sounds seriously and acting quickly protects your investment and maintains a comfortable home environment.
Common Strange AC Sounds
Banging Sounds
A loud banging sound from your air conditioner likely means a loose component rattles inside the unit. The indoor unit might also be off-balance. This noise clearly indicates something is wrong and needs immediate attention to prevent damaging your AC further.
Not addressing this issue can lead to significant wear and tear on your unit, potentially causing expensive repairs or even the need for a complete replacement. It’s essential to have a professional technician inspect and secure any loose parts promptly.
Clicking Sounds
Clicking noises are common when your air conditioner starts up or shuts down and are related to the electrical components. It is usually normal. However, if the clicking is constant, it likely points to a problem that requires professional repair. Persistent clicking could indicate issues with the thermostat or a failing control panel.
Additionally, continuous clicking can indicate a relay issue or a malfunctioning capacitor, which a qualified technician should address to prevent further electrical problems and ensure your system runs smoothly.
Screeching Sounds
If your air conditioner emits a screeching noise, it could mean it needs lubrication. However, it might also indicate a more serious issue, such as high internal pressure. Screeching sounds often point to problems with the fan motor or a compressor experiencing too much pressure.
If left unresolved, these issues can lead to motor failure or significant damage to the compressor, which are expensive repairs. Prompt attention from a professional can diagnose the exact cause of the screeching and implement the necessary repairs to keep your AC running efficiently and safely.
Addressing Strange Sounds
The Importance of Prompt Action
While some noise level is expected, new and unusual sounds should always be taken seriously. We rely heavily on our air conditioners, so addressing any minor problems before they develop into major ones is vital. Ignoring these warning signs can lead to a cascade of problems that affect your system’s overall performance and reliability. Early intervention can prevent further damage and maintain the efficiency of your air conditioning unit, ensuring you stay comfortable throughout the year.
Additionally, addressing issues promptly can help you avoid emergency repair costs. When problems are caught early, they can often be fixed quickly and inexpensively. By taking action at the first sign of trouble, you protect your investment and ensure your air conditioner operates at its best

Benefits of Timely Repairs
Addressing strange AC sounds promptly can prevent minor issues from turning into major, costly repairs. Ensuring your air conditioner functions correctly enhances its efficiency and lifespan. Regular maintenance and timely repairs save you from the inconvenience and expense of a total system failure. Keeping your air conditioner in top shape improves indoor air quality, as a well-maintained system is less likely to harbor dust, microbial growth, and other allergens.
Timely repairs can also lead to significant energy savings. When your air conditioner operates efficiently, it uses less energy to cool your home, reducing utility bills. Over time, the savings on energy costs can offset the expense of regular maintenance and repairs. Additionally, a well-maintained air conditioning system is better for the environment, as it consumes less electricity and reduces your carbon footprint.
By incorporating these practices into your regular home maintenance routine, you ensure that your air conditioning system remains a reliable and efficient component of your home’s comfort system. Regular attention to your air conditioner prevents costly repairs and contributes to a more comfortable and healthier living environment.
Preventive Measures
Regular Maintenance
Routine maintenance is essential to prevent strange AC sounds and other issues. Regular check-ups help identify potential problems before they escalate, keeping your system in top condition.
Homeowner Tips
As a homeowner, you can take steps to maintain your air conditioner. Keep the area around your outdoor unit free of debris, replace filters regularly, and stay alert to any changes in your system’s performance.

What Our Customers Say About Us






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"?

Miguel was extremely helpful and quick to fix. 10/10 recommend Miguel and goettl

My house is a 1944 home with some old pipes. There's no "let out"
Plumbing specialist Andrew came up with the option to remove the toilet and use the camera and auger. Found out the problem was one of the pipes below is cast iron with jagged edges,in which tp would get caught up and in time caused the clog.
He cleared the pipe and everything is draining properly now!
He did mention on replacing the old pipe because of the jagged edge situation, but my budget is a bit on the tight side in which I have to put it off a little longer, he understood. We both agreed on limiting tp flushing,especially with little ones.
All in all great experience 5 stars to Goettl and 5 stars to Andrew, thanks man!
PS: I paid $408 for everything
For me a reasonable price due to the labor I saw and tools that were used, but ultimately my toilet fluhes and my shower drains!








As usual we are very satisfied with Goettl





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

We had Edgar come out to inspect our new home today and he did a very thorough inspection. He made sure the unit was checked so when the warranty company comes out we have all information possible. Amazing customer service and very personable
Edgar came back after a warranty inspection was done on the home by the install company. He found errors and was amazing at documentation of the issues. If I could give more than 5 stars I would.
Peter and Josue came out today to do an additional check on our unit with humidity issues. The weather was not conducive to having the outdoor pressures checked and they were very thorough with an interior check. Very professional and knowledgeable.
Tyler b was very professional today and gave great recommendations for upkeep of our unit in



Highly recommend Goettl


They had the right solution in my time of need. I'll be returning for future services, no doubt.








He was my technician from another company. I’m always happy with his service that’s why I’m following him.
Thank you Colby , you are the best technician I’ve ever had .
I really do appreciate your work!!


He arrived promptly and was very professional.
We are first time customers and from now on we are calling Goettl for all our plumbing needs.
Thank You.



Andrew came in and unclogged the bathroom sink and cleared out the line . We used the Smart Sadie program for it.
Thanks Andrew and Ian and Goettl!







Overall, an awesome tech. I would love for him to be my designated technician for any future service calls for my AC unit. Thank you for a wonderful experience!


I’m very happy with the seamless experience.



Great communication




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 am very thankful for their help today.

Update 4/21/25 - Mike did a wonderful job. Made suggestion to keep my system running well for more years to come.
‐---------------------
Update: 12/3/24 - Jacob is great. He fixed the leaking parts on water softener and also checked the water heater to see what can be done with that. He is efficient and very knowledgeable and reviews everything so you understand.

Update: 7/25/24 - had some more work done today. The folks who come to service, install, etc. are great. They know their job, are very efficient and friendly. Today it was Justin and Luis who were installing a new filter system. Looking forward to not have to change filters every month. Thank you, gentlemen, for all the hard work in the heat.
‐----‐-----------------------------
They said I needed to replace my a/c. I was given a choice of 5 units. I liked that the 2nd most expensive would balance the temperature in my house. I get full west in my living room in the afternoon. It is always 10 plus degrees hotter on my sofa, than rest of house. So I paid a fortune and it isn't doing what he said it would. They came back and added another vent to my living room. Better, but still not what I was told. I could saved $10k and got the cheaper model. Don't think I have much recourse to get this fixed. The technicians are very good, too bad their salesmen and products are not up to the same standard.





























A special shout-out goes to Pablo, our technician. He was on time, friendly, and extremely knowledgeable. Pablo took the time to explain everything he was checking, walked me through the condition of each component, and gave helpful tips on how to keep our system running efficiently year-round. His attention to detail and pride in his work really stood out. Because of his professionalism and the overall quality of service, Goettl has definitely earned my trust and future business.
Highly recommend Goettl HVAC—and if you can, ask for Pablo!

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.

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.








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!
