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.

1/13/2025 Nathan Bloodworth was a great tech very thorough, quick, and friendly. Great job!
8/13/2024 Joe Benavides was very professional and kind. He worked diligently to unclog my drain in my master bath and cleaned up when he was finished. We got to chat while he worked and he is such an awesome individual! Another great experience from Goettl! 👍
Darrell Gonzales did a wonderful job and was very thorough! Very professional! Goettl hires great people give them a call! 📞 👏
Thank you Goettl you are my new "go to" service company.
Thanks Clayton and Goettl!
The following day, Jesus Gloria came out to inspect and service my HVAC. Again, I couldn't have asked for better service. Jesus was knowledgeable and took extra steps to ensure there were no further issues with my unit.
I wouldn't think twice about using Goettl Air Conditioning & Plumbing again!
We discussed options and agreed that a detailed lcleaning and sewing of all the ducts should eliminate this problem. He discussed financing and, and returned the following morning to make all the arrangements. He also advised us not to continuously run the A/C fans when the unit was not cooling, which seems to have helped with the humidity already, even though the duct work isn’t scheduled for a few days hence.
It was a pleasure to work with a knowledgeable A/C technician who could quickly isolate the cause of our problem and arrange a solution.
Alex was great with tune up and customer service!
Darean Guerra was awesome and fotnthe job done. Thank you!
Jesus Gloria – Goettl Plumbing & A/C
Jesus Gloria was many things: professional, proficient, polite, easy to talk to, and a true pleasure to have in my home.
He’s exactly the kind of professional you want handling your service needs. Jesus explained everything clearly and patiently—no jargon, no pressure. Let’s be honest, customers like me can be tough—we want 5-star service on a shoestring budget—but Jesus never missed a beat.
I made several changes during the project—adding services, canceling others—and Jesus handled it all without delay. No need to call the office or rework paperwork. He updated the order, adjusted pricing, and gave me a clear face-to-face explanation on the spot. All same day.
That’s outstanding service.
Goettl may not be the cheapest company out there, but they’re professionals who exceed expectations and hire top-tier people like Jesus. That’s why I’ll remain a loyal customer.
Jesus Gloria has my back—and I have his.
Thank you
UPDATE: one of the area service managers contacted me after my review and apologized and stated they wanted to rectify the situation and asked about my service quote from the company I decided to go with. He wanted to do the service at the same price and deduct the $428 I previously paid for diagnosis and throw in 2 years of maintenance. He told me he would talk with his boss and call me the next morning. He told me to email the other quote. I emailed him and he gave me his number. I never heard from him again! He never called me the next day as he said he would or replied to my email at all. So I am now adding that they do not keep their word either to this review! Horrible way to do business. Go with ASC heating and air where they know how to treat people with compassion, keep their word, give free second opinions, have veteran discounts, great customer service- Marsha is great and so is Ron 😊
Nathan came by promptly and inspected plumbing, and caught an issue under warranty for us!
Just an update, Andrew Morgan came and rejuvenated our system and did a wonderful job. His communication was clear and efficient.
07/23/25 Update. After getting the new larger duct to the master bedroom, it still wasn’t cooling properly. Goettl sends out another tech that actually knew what he was doing. Tech Billy McDermott found the problem. There was an opening on the back of the unit in attic that was blowing cold air into the attic. Once he sealed it up, low and behold the cold air is now coming into the living areas and the set temp is holding. I am leaving this rating at one star because after several techs coming out and telling us it was an airflow issue and we spent an extra $6K on insulation, come to find out none of the techs including a supervisor could find the problem. From now on if we have issues with HVAC, I want Billy to come to our house.
AC not working again since Friday night (8/8/25). I contacted Goettl as instructed, not satisfied with the response, still waiting for resolution and contact/communication from a manager.

7/30/25 Update:
Goettl assistant install supervisor Nacho and his crew (Manny & Julio) assessed the entire system again today. They were polite and professional and made sure all our concerns were heard and addressed. It is believed the issue has been identified and fixed. Thanks Goettl for making the situation right!
7/22/25 Update:
Issues continue. Techs to arrive again today. Updated review to follow pending outcome.
7/2025 Update:
Goettl service technicians have returned to assist with some issues. Both Ian P. and Will M. we're both very professional it was believed issues were resolved. Dispatcher Betty was also able to hear my issues and arrange for a tech to arrive as quickly as possible.

Initial review 2/2025:
Jorge "George" was respectful and easy to communicate with. He listened and answered all our questions. Informed us of what and how Goettl could do with the 20+yr old system in our home, and gave us time and space make the best decision for us. So far very pleased with Goettl's professional conduct and standards.
Thanks you
What stood out the most was their attention to detail and genuine care for customer satisfaction. They took the time to assess my system thoroughly, offered honest recommendations, and completed the work efficiently without cutting corners. My home is now noticeably more comfortable, and I feel confident knowing everything was handled by true professionals.
If you’re looking for reliable, top-quality HVAC service, I highly recommend Goettl. They truly live up to their reputation and exceeded my expectations in every way.
Roger came for my rejuvenation appointment. He was very curtious and knowledgeable. I was happy he showed up prompt with great respect to my AC unit and property. I relaly appreciate him and his attention to detail. I would highly recommend him for any of your AC needs.
Jesus Gloria AC service review. He did a great job today and I would highly recommend him for any AC service needs. He was very knowledgeable and courteous. He helped add a surge protector on my outside unit for added protection. I look forward to working with him in the future.
Well, I had some plumbing issues at my residence, and I called "Goettl Plumbing." Great results, too 🤗.
My water wouldn't stay hot, and after contacting Justin at Goettl Plumbing, he sent out Frank, a service technician with over 20 years of plumbing experience. Frank spent a good bit of time studying/ evaluating my plumbing functions, consulted with an on-site Goettl supervisor, and determined my plumbing issues.
After they conferred those issues with Justin, a plan for resolution and payment was determined, and work started the next day.
Greg arrived that morning; accessed the work areas, determined the tools and equipment he needed, and got right to work.
By the end of the day, Greg had installed three (3) Replacement Single Handle Tub/Shower Valves, a Pressure reducing valve, and a Thermal expansion tank with vacuum breaker - - RESULTS: Hot Water 💧
In two days, I witnessed Super Communication, Super Teamwork, and some old-time "1990-1991" Professionalism ... thanks,
"GOETTL Air Conditioning & Plumbing" for A Job Well Done 👏🏼
After note. Cameron came back by a day later to check on readings he wasn't able to get on first appointment. I have high confidence in his work. I'm very likely to work with them again
Brayan and Marcos did an awesome job on the new ac installation. Installed with no issues and has been on ever since. Perfect time with summer coming up. Walked through and job was very clean and organized. Great work ethic. Great guys.
Update - our air conditioner went out today (10/26/23) and JEHAD showed up to repair the issue but the issue was bigger than expected. Tomorrow we will have a brand new system! Goettl is an EPIC firm that treats customers right. Thank you again JEHAD for going above and beyond.
Goettl is the epitome of what excellent customer service is! Our Drain King, DAREAN, addressed all of our questions and concerns and not only unclogged our drain but went above and beyond to show us our drains leading to the street were free and clear of any other issues. Thank you Darean and thank you Goettl for a great experience!
Update: great experience with Edgar Loredo who kept it real with us and was very transparent. I appreciate his honesty and recommendations. Will be requesting him as our technician in the future if we choose to use Goettl
