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.

Thank you for your dedication to doing things right

Nov 05 2025: Seasonal maintanence checkup and this go around I got Adam. Not one bit less experienced. I was given heads up of his arrive. He came, performed his maintenence inside and out and at the end provide his assessment alone with photos. Goettl techs don't come in and leave in 15 minutes, they are through in what they do. Great job Adam.

Devin performed my plumbing inspection. He is knowledgeable and courteous.


What truly stood out was his attention to safety. He identified a carbon monoxide concern in our home and made sure we understood how serious and dangerous it could be. José explained the risks in a calm, respectful way and ensured we knew what steps to take to keep our family safe.
His professionalism, knowledge, and genuine care went above and beyond. We are incredibly grateful for his honesty and dedication, and we highly recommend José Carreon to anyone needing HVAC service.
Thank you , Goettl for hiring the best technicians!






















Jesus was terrific, thorough, and personable. Made everything so easy for me.
I just had my second yearly inspection with Francesco Tocci. I cannot say enough good things about him. He is prompt, professional, personable, and takes the time to explain his findings to me and what he will do about them. Now, in fairness, all of the technicians from Goettl are great. But Francesco stands out because of his gregariousness. It is obvious that he loves his work and truly cares that his clients are happy with the job he does.





We installed a new AC unit...we got a best price...and the same day day they show up, and 9 hours later...the new ac was on working. Well we have had scheduled an appointment for today for AC mentanance....the technician Kevin Schroeder show up on time...he was very professional, very knowledgeable...polite..and permanently he try to assure us about everything . Such a great person, and a joy to be in our house . Strongly recommend Goettl company, and it's a pleasure to recommend this technician ! Great job Kevin 👏






I initially had a rocky start with one particular representative, but the Goettl team stepped up and made it right, which says a lot about their integrity as a company. Billy did an outstanding job and made sure my system was safe, fully operational, and gave me real peace of mind.
Thank you to management, Josh and Josue, for personally ensuring the job was completed to my satisfaction.





Nick, Julian, and Josh were at my home for four days. They did a meticulous job, cleaning up every day with no debris left. They were responsive to my questions and took pride in their work. They explained the work to be done in great detail.
The work team was terrific, and I would have no hesitation in using them again or recommending them.


Did a great job. Answered all of my questions and showed me how to take care of my equipment. They talked to me not at me. Thank you both of you.
Patty 🤗🌷🌵







Update on 1/10: Ashton was very helpful and informative. He did a good job and gave good communication!


Ashton was a great tech. Jumped right into the maintenance check ensuring our systems were up and running as should be. Following his tune up and inspection, Ashton thoroughly went over all his findings before cleaning up.
Nate is a fantastic Goettl tech. Came out to fix one problem but quickly realized the diagnosis was not correct. Stayed at our house, relentlessly working to figure out the issue all while in a house with no A/C, registering indoor well above 90. Thanks to Nate, David and Goettle for getting us back up and running and taking care of us and making the invoice total right. Great customer service in this experience.

Jeremy was fantastic. They were able to get us in earlier than scheduled. He remembered the house and was able to due the maintenance tune up and test the system in no time. Great experience.
12/26/24
Francesco is a top notch plumber. On time and got right to work. Did all his inspections and was in and out in no time. Stuck around after his inspection to talk about what he found and made some minor recommendations. Awesome experience.














Julian and his team (Joey, Jeran, and Alonso) are extremely knowledgeable, efficient, and worked hard to get us back up and running as quickly as possible. Upon completion they send a detailed email with pictures.



Thank you!



I am very satisfied with my Goettle services, their employees, including the scheduling staff, and highly recommend this company.

Goettl plumbing supervisor, Craig Cooper, arrived to survey the problem. Craig determined the valve had been incorrectly installed during the previous water system installation. Craig immediately contacted water mitigation supsrvisor, Ethan Gray at Quick Restore LLC.
Craig coordinated with Ethan the construction, drying of walls/carpet and services for the boxing and storage of our personal property. The reconstruction and repair work was done professionally and in an outstanding time frame for me to undergo major spinal surgery.
I wish to thank Craig for his outstanding integtity and attention to detail for this undertaking. He arranged for Goettl to cover all the costs involved for the work, boxing, moving, storage and water mitigation.
We are so very grateful to Goettl for their wonderful work ethic, technicians and supervisors. We absolutely continue to use and wholeheartedly endorse Goettl for all our AC and plumbing services! Thank, you again Craig!




Parker was very pleasant, knowledgeable and respectful of us and our home.
You’ll be in good hands with Parker and Goettl











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!






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!
