7 Signs Your Air Conditioner Needs Repairs
As the summer heat intensifies, your AC breaking down is the last thing you’d want. A 100% reliable air conditioning system is a bit of a cliché, but catching issues early can minimize damage. Keeping your air conditioner in optimal shape will help you recognize the following seven signs of trouble, so you know when to schedule repairs.
1. Increased Cooling Costs
If your air conditioning bills give you chills, you need to check your AC for efficiency. An inefficient system will have to work doubly hard to provide that cooling effect, causing increased energy consumption. Consider scheduling a repair if you notice a significant spike in your cooling costs.
Understanding the Impact of an Inefficient System
An inefficient air conditioning system can cause financial strain. When your AC works twice as hard to cool your home, more energy is consumed, increasing your bills. Some things that can cause your AC to become inefficient include dirty filters, refrigerant leaks, or worn-out components. Deal with these issues promptly to avoid further financial strain.
Monitoring and Managing Cooling Costs
Keeping track of your energy bills and comparing them to previous months or years will allow you to monitor your cooling costs effectively. If you notice a sudden and significant cost increase, it indicates a problem with your air conditioner. You can avoid it by scheduling regular maintenance checks to ensure your AC operates efficiently.
2. Decreased Cooling Output
A major sign of a malfunctioning air conditioner is that it struggles to cool your home effectively. You must not ignore this issue as it can lead to further damage. Make sure your AC is the right size for your home and seek professional help if you notice a decline in performance.

Understanding the Causes of Poor Cooling
Decreased cooling output from your air conditioner can signal several problems with your system. These include dirty air filters, refrigerant leaks, malfunctioning components, or improper installation. You may need professional help to find the root cause of the problem to restore your AC’s cooling efficiency.
Addressing Decreased Cooling Output
If your AC struggles to keep your home cool, you must take prompt action. Checking and replacing your air filters for proper airflow is a good place to start. If the problem persists, you may need a professional inspection to diagnose and repair any underlying issues. Additionally, ensure that your AC is properly sized for your home’s cooling needs; an undersized unit may not cool your space efficiently.
3. Unusual Sounds
Loud or unusual sounds from your AC unit are not normal and signal a problem with your system. If you hear anything unusual, such as grinding, squealing, or banging, get your AC inspected by a professional.
Identifying Common AC Sounds and Their Causes
It is normal for your air conditioner to produce some noise during operation, but certain sounds can indicate underlying issues. For example, a grinding noise is a sign of malfunctioning motor bearings, while a squealing noise may suggest a worn-out belt. Banging or clanging sounds could signal loose or broken parts. Recognizing these sounds can help you diagnose the problem early.
Take Action Against Unusual Sounds
Do not wait to have your AC inspected if you hear any unusual sounds from your unit. Ignoring these sounds can cause further damage and potentially costly repairs. A trained technician can tell you the noise source and recommend repairs to restore your AC’s performance. Regular maintenance can also keep these issues from happening in the future.
4. Strange Smells
A musty or pungent odor from your air conditioner could indicate microbial growth. It affects the air quality in your home but, more importantly, indicates a potential problem with your AC unit. If you notice any strange smells, have your unit inspected and repaired if necessary.
Recognizing Different Odors and Their Causes
There are several reasons for strange smells coming from your air conditioner. A musty odor, for example, could suggest microbial growth within the unit. A pungent smell, on the other hand, may indicate a burnt wire or insulation. Understanding the source of the scent can help you address the problem effectively.
Addressing Strange Smells
If you notice any unusual odors from your air conditioner, you must act promptly. Check your air filters and change them if they are dirty. If the smell persists, schedule a professional inspection to identify and resolve the underlying issue. Ignoring strange smells from your AC can compromise indoor air quality and put you at risk of potential health hazards.
5. Poor Air Quality
A decline in indoor air quality should alert you about potential problems with your AC. A malfunctioning AC can circulate dust, allergens, and other pollutants, causing respiratory issues and discomfort. Regular maintenance and prompt repairs can improve air quality and keep your home healthy.

Understanding the Impact of a Malfunctioning AC on Air Quality
A malfunctioning air conditioner often causes poor indoor air quality by circulating dust, allergens, and other pollutants throughout your home. It can cause several health problems, including respiratory conditions, allergies, and discomfort for you and your family. You must identify and resolve the root cause of the issue to improve air quality and maintain a healthy living environment.
Improving Air Quality Through Regular Maintenance and Repairs
Regular maintenance and prompt repairs can improve air quality in your home. You should schedule regular HVAC inspections and filter replacements to keep your air conditioner functioning properly. If you notice a decline in air quality, such as increased dust or allergens, contact a professional to inspect your AC unit and address any issues affecting air quality.
6. Leaks or Moisture
Any leaks or moisture around your air conditioner could indicate a problem with the unit. Leaking refrigerant or condensation can cause serious issues if not addressed promptly. If you notice any leaks or moisture, contact a professional for inspection and repair.
Identifying the Source of Leaks or Moisture
Leaks or moisture around your air conditioner may indicate leaking refrigerant or condensation buildup. You must identify the source of the leaks or moisture to determine the appropriate course of action. Leaking refrigerant, for example, can harm your health and the environment and should be addressed immediately.
Addressing Leaks or Moisture Issues
If you notice any leaks or moisture around your air conditioner, contact a professional for inspection and repair. Ignoring it can further damage your AC unit and cause potentially costly repairs. A professional can find the source of the leaks or moisture and recommend the necessary repairs to restore your AC’s performance.
7. Thermostat Issues
Your AC’s performance will be affected if your thermostat is not functioning properly. Incorrect temperature readings or an unresponsive thermostat can cause inconsistent cooling and discomfort. Ensure your thermostat is calibrated correctly and replace it if necessary.
Recognizing Common Thermostat Problems
A malfunctioning thermostat is often the cause of inconsistent cooling and discomfort in your home. Common thermostat issues include incorrect temperature readings, unresponsiveness, or erratic behavior. These problems can affect your air conditioner’s performance and efficiency.
Resolving Thermostat Issues
If you suspect your thermostat is malfunctioning, you can take several steps to resolve it. Firstly, check the thermostat settings and ensure they are set to the correct temperature. If the problem persists, recalibrate or replace the thermostat. A professional can help diagnose the problem and recommend the best action.

What Our Customers Say About Us


Highly recommend Goettl Air Conditioning and Plumbing!!!




Jesus Pacheco arrived for the final repair and completed the repairs faster than quoted. After, he showed me the repairs and explained everything thoroughly. I’m am extremely happy with the services completed and have no worries in the quality of work done. Thank you!




HOWEVER, the estimate provided was exceptionally high and not market in my opinion.






Update:12/18/25
Stacy did an absolutely wonderful job checking our hvac system. In addition my husband asked about insulation and as it turns out Goettl does indeed do insulation. Stacy spent a lot of time taking pictures of our attic and showing them to us and patiently explained everything to us.
He is a very pleasant and friendly person and I would not hesitate to have him do all of our hvac inspections. He was very thorough and even checked our outside a/c unit and changed the Capacitor.
Benton was equally pleasant and very helpful on the phone and we booked the insulation install for the following week.
I would not hesitate to recommend Goettl. Customer service counts a great deal to me and Goettl really takes care of it's customers.
Update: 12/19/2026
Tim Theriot reinsulated my attic today. As usual for Goettl teams, he did a wonderful job. He and his team member (Francisco?) cleaned up nicely.
Benton again was wonderful to deal with.



Excellent service from start to finish. My service technician, Josue Diaz, went truly above and beyond. He was professional, knowledgeable, and took the time to explain everything clearly. You can tell he takes pride in his work and genuinely cares about doing the job right. I couldn’t have asked for a better experience with Goettl. Highly recommend both Josue and the company.





I’ll post an up dated message when the guys finish the work! Work is done! Just waiting on concrete and inspection! Zack Adolfo Jalen Sam Chis have been outstanding! There work ethics have been phenomenal very very pleased with the work just waiting to finish everything up so I can get my house back thank you Goettl Plumbing!







...... we had an AC problem a few days later. Peter Medelez from Goettl came out and fixed it expertly and made some recommendations to ensure it won't happen again. Some things hadn't been done correctly when it was installed several years ago (by someone else), and he will be back next week to fix them. I highly recommend Goettl.
... 10/15/25 ... we had a leak in the main water line which was running into the neighbors' yard. In less than two hours of calling Goettl, Clayton Purvis arrived to fix the leak. He repaired the leak and fixed connections, and repaired something previously done incorrectly in the unknown past. He was done before we had to leave for a prior equipment. I feel confident in the quality of work, as I always am when I have to call Goettl for something.
12/17/2025. Tyler Brockhausen was the technician from Goettl who inspected our heating system today. He did a thorough check and changed the filter. He covered his shoes every time he entered the house, left no mess on the floor. It is comforting to know that all is working correctly.


Eric and another man came to my house to clean my ductwork. Goettl had explained to me about promotion during my winter rejuvenation. Eric explained the procedure to me. Helped take down some child gates and then helped replace them when done. Always kept me informed of status and explanation of findings. Goettl may be on the costly side but well worth it. Communication is great and Smart Sadie program is great.
Again Eric and the other man (I apologize for not remembering his name) were friendly and always communicated what was happening.

Both your Plumber Technician, Josh Munoz and his Service Manager, Ben Tracy were extremely helpful.
Josh drained the hot water heater and conducted a thorough inspection of all our plumbing – both floors – inside (5,500 sq ft) as well as outside and identified several issues which he quickly set about fixing.
Josh was friendly, informative and professional throughout the entire process and served as a great representative of your company and team.
Speaking of which – every time Josh needed to check in with management Ben made himself available as a resource. It was clear that they were working as a team.
Once again ➡️ Thanks for all the great work and special kudos to Josh.






But you can’t put a price tag on your life!!
So thanks to my hero.

work.
Just want to thank Goettl for hiring such coptenent personnel that have good personality if could give him 5 stars they do such an outstanding job! JOHN! And ABEL



Stacy was very professional and knowledgeable. He explained everything showed me pictures and explained some options for me. He explained some parts are starting to wear. Thank you Stacy for your service. I would recommend him.
Jesus and Andrew were very professional and knowledgeable about my service and explained and booked my services. Showed pictures and explained other packages that are a available. They both were very pleasant. I would recommend them.









Douglas was thorough and checked for leaks. We found that the issue was a main water break. He was unable to check my water heater since the water in it drained without any water pressure. He unplugged my water heater to avoid damage to the elements. He also suggested To leave the hot water valve open, once the water came back on. Water returned after midnight. I allowed the tank to fill and plugged it back in. I had hot water this morning.
I had a follow-with Daniel, since I needed further information on understanding my Sensi thermostat & my heatpump funtions. His patience and explanations were exemplary! Awesome experience. Thank you Daniel!



Pipes, all under the house with low clearances. Alan and partners did a very professional and considerate work. I'd recommend them to anyone.





Update: Eric and Momo came out afterwards to clean the HVAC coils and ducts, and they also provided amazing service and also went above and beyond. Thank you both for your kind, helpful, and efficient work!




Knowledgeable. He made sure to explain what my visit was for and what to expect. He let me know what he found and was able to fix what needed to be fixed. He was early and accomplished the work quickly.

Incredible service from Brent, who came out and was incredibly knowledgeable in his craft. Can't say enough good about the guy. Thank yall for taking care of us!







He did an excellent job on the entir9mme system. I'm very pleased at Goettl's standards. Thank you. I will definitely have them back again!!!

Excellent service.

was professional, kind, knowledgeable, thorough and fixed the problem. Stephen for the win!!!! Would recommend Goettl to anyone. We have tried lots of other companies but stopped trying them when we found Goettl. They are the only ones we use for any HVAC or plumbing issues. Great, friendly service.



A short history. A few years ago, we had four seasons put in a new furnace. After checking around and getting tons of estimates, there was as much as a $10,000 difference between all of the estimates. Four seasons came in at the best price. Unfortunately, I ordered an 80,000 BTU furnace and when the guy was done, I looked at the furnace and saw that it was a 60,000 BTU. I showed the guy the invoice and basically his response was ‘ Oh crap’ so I talk to the manager and he assured me that 60,000 BTU would heat my home sufficiently since it was a high-efficiency unit.
I was ready to have them tear it out and put the right one in, when the manager guaranteed the furnace and gave me the price for the 60 KBTU with a substantial discount. I did the regular maintenance and service service with four seasons.
When Goettl took over, I’m not sure if they just change the name, or bought four seasons, but everything changed after that. First I was informed of a membership called Sadie which is basically a yearly/monthly fee that allows us to get a lot of benefits. Free service calls, free, free preventative maintenance and discounts on non-covered items.
The first thing that I noticed was Josh came in to do a service, check the pressure and saw that the original installation guy did not convert my furnace to propane. Apparently none of the other service people ever checked the pressure. He had to return with the correct parts and changed out the valve. He also helped me out with a bathroom heating duct that was ripped. The price was great and he said he felt bad that we had such issues with the previous company.
A few months later (last Saturday) we stopped getting heat. I called Goettl let them know, and they were at my house within two hours. When it’s freezing outside or going to be subzero it’s really important when they respond so quickly.
Chris was the technician and he found the problem, however, the plumbing supply company was not open till Monday morning. Two days with sub, freezing temperatures scaring me a bit. Chris said that he would check with Dispatch and see if they had a couple of space heaters. When he was leaving, he noticed we had a bunch of firewood on the front and he offered to help bring firewood in. I told him no problem we had it, he said he was happy to help us. Make sure we had enough firewood to get through two days.
These two offers, were above and beyond in something you really wouldn’t expect from your HVAC people. Unfortunately, they didn’t have any space heaters at Dispatch, so we went to Home Depot and got some radiator heaters and then yes 24 hours a day kept a fire going.
Chris showed up Monday about 11 AM with the parts and it took him about 2 1/2 to 3 hours to fix all of the problems. I’m not savvy with all of the HVAC terms, but something about condensate water bill backed up through the system blah blah blah… we now have heat. lol.
Getting the Sadie member membership/club was the best thing we decided to do. They call us regularly to schedule our summer and winter maintenance. They are responsive. And they are very polite every time I call them.
I really would recommend you contacting them and get on that membership before you actually need them. Thank you, Josh and chris and unfortunately, I cannot remember the name of the female technician that came out and changed our filters but she was awesome also!

My wife and I are upgrading our home with the new water purity package and cannot wait to try our new water.Thank you Joseph or the service you provided and information you shared.I highly recommend joseph and goettl!


I look forward towards the next project. Thanks!





By the end of the day, I had hot water and Mark left no sign of a mess behind.
I was surprised at such fast service and impressed by everyone I interacted with.
Great company!







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.








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!












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

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.








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!
