Can I Do My Own AC Repairs?
Attempting do-it-yourself repairs on your AC can be tempting, especially for the more hands-on homeowners. However, it’s crucial to know your limits when it comes to HVAC systems. Working on your AC without professional experience and training can cause further damage and safety hazards.
While you can perform some maintenance tasks to keep your system running smoothly, such as replacing air filters, major repairs should always be left to the experts. Let’s explore why attempting AC repairs is not advisable.
If you’re facing AC issues and need repair services, it’s best to call a professional like Goettl Air Conditioning & Plumbing for assistance.
This article discusses the risks and challenges of attempting DIY repairs on your system, emphasizing the importance of professional expertise and training. It provides insight into why major repairs should be left to HVAC professionals and offers a cautionary perspective on AC repair’s potential dangers and complexities.
Why DIY AC Repair Is Not Recommended
When faced with an air conditioning malfunction, the temptation to tackle the repair yourself might be strong. However, do-it-yourself AC repair is not recommended for several reasons as air conditioners are complex and require specialized knowledge and tools to repair properly.
Attempting to fix your AC unit without the necessary expertise can lead to further damage, safety hazards, and inefficiencies. Here are some main reasons why AC repair is best left to the professionals.
1. Safety Hazards
AC systems involve electricity and moving components, such as fan blades, which can be hazardous to handle without proper training. HVAC technicians undergo safety training to mitigate these risks and ensure safe repairs. Understanding the risks involved highlights the importance of hiring trained HVAC technicians for repairs. Let’s explore these hazards in more detail.
Electrical Hazards
Handling electrical components of an AC system without proper training and tools can be disastrous. High-voltage electricity powers the compressor, fan motor, and other critical components. Incorrect handling can result in electric shocks, burns, or even fires. HVAC technicians are trained to safely work with these components, minimizing the risk of accidents.
Additionally, HVAC technicians are equipped with the tools and personal protective equipment (PPE) to handle electrical components safely. They understand the importance of shutting off power to the system before beginning work and follow strict safety protocols to prevent accidents.
Furthermore, they are trained to diagnose electrical issues accurately, ensuring that repairs are done correctly and safely. Hiring a professional technician can help you avoid potential hazards and keep your home and family safe.
Refrigerant Risks
Air conditioners use refrigerant to cool the air. This refrigerant is a chemical that can be harmful if not handled properly. HVAC technicians are trained to safely handle, recover, and dispose of refrigerant according to environmental regulations. Attempting to work on your AC system without proper training can lead to leaks, releasing harmful chemicals into the environment.
Mechanical Hazards
AC systems have moving parts like fan blades and motors. These parts can cause injuries if not handled correctly. HVAC technicians are trained to safely inspect and repair these components, ensuring they are properly aligned and functioning. Attempting DIY repairs without proper knowledge can result in accidents and injuries.
HVAC technicians also have the expertise to identify worn or damaged components during routine maintenance, preventing potential mechanical failures. They use specialized tools to inspect and adjust fan blades, motors, and other moving parts to ensure they operate smoothly and efficiently.
Additionally, technicians are trained to follow proper safety procedures when working with these components, reducing the risk of accidents. Hiring a professional technician for AC repairs can help you avoid injuries and ensure your system operates safely.
Structural Integrity
AC units are heavy and can be installed in elevated areas such as roofs or attics. Working on these units requires proper safety equipment and training to prevent falls or structural damage. HVAC technicians are equipped with the necessary tools and knowledge to access and work on these units safely, minimizing the risk of accidents.
In addition, HVAC technicians are trained to assess the structural integrity of the installation location before performing any repairs or maintenance. They ensure the mounting brackets and supports are secure and can withstand the unit’s weight. Technicians also inspect the surrounding area for any damage or deterioration that could compromise the unit’s stability.
Technicians are also familiar with safety regulations and guidelines for working at high heights. They use proper fall protection equipment, such as harnesses and lanyards, to prevent accidents. Additionally, technicians are trained to work in confined spaces, such as attics, ensuring they can navigate these areas safely.
Hiring a professional HVAC technician for repairs and maintenance ensures that your AC unit is serviced safely and efficiently, lowering the risk of accidents or damage to your property.
Code Compliance
HVAC units must comply with building codes and regulations to ensure safe operation. HVAC technicians are familiar with these codes and ensure that any repairs or installations meet these requirements. DIY repairs may not adhere to these codes, leading to unsafe conditions and potential legal issues.
2. Risk of Further Damage
Attempting DIY repairs without the necessary knowledge can further damage your AC system. AC systems are complex and require a balance of various parts. Making correct adjustments can keep other parts in sync. Let’s dive into the risks involved in DIY AC repairs.
System Imbalance
AC systems are designed to work harmoniously, each component playing a specific role. Making incorrect adjustments to one part of the system can disrupt this balance, leading to inefficiencies or failures in other components. HVAC technicians can diagnose issues comprehensively, ensuring that any repairs maintain the system’s balance and efficiency.
Component Compatibility
AC systems are made up of various components that work together seamlessly. When one component fails, it can affect the performance of other components. HVAC technicians understand the compatibility of different components and can provide replacements that properly integrate into the system. DIY repairs may result in using incompatible parts, leading to further damage and inefficiencies.
System Calibration
AC systems require precise calibration to operate efficiently. This calibration ensures that components work together optimally to provide the desired cooling. HVAC technicians have the gear and knowledge to calibrate AC systems correctly. Incorrect calibration due to DIY repairs can result in overworking certain components, leading to premature wear and system failure.
Warranty Concerns
Many ACs have warranties that require repairs and maintenance by authorized technicians. You risk making these warranties void if you attempt AC repairs yourself. HVAC technicians are authorized to perform repairs under warranty, ensuring your system remains protected.
Professional Diagnosis
HVAC technicians undergo extensive training to diagnose AC issues accurately. They use specialized tools and methods to identify underlying problems and recommend appropriate solutions. Attempting DIY repairs without a thorough understanding of the system’s operation can result in misdiagnosis and ineffective repairs, leading to further damage and costly repairs.
3. Addressing the Root Cause
HVAC systems are intricate, and problems are often more than surface issues. Professional technicians understand how the system works together and can identify and address the root causes, not just the symptoms. Let’s explore why professionals are better equipped to handle complex HVAC problems.
Comprehensive System Evaluation
HVAC technicians thoroughly evaluate your AC system to identify the root cause of the problem. They inspect all components, including the compressor, condenser, evaporator coil, and refrigerant lines, to address the underlying issue.
Identifying Underlying Issues
Many AC problems have underlying causes that are not immediately apparent. HVAC technicians use diagnostic tools and their expertise to pinpoint these issues and develop a targeted repair plan. DIY repairs may only address the symptoms, leading to recurring problems.
Preventing Future Issues
By addressing the root cause of AC problems, HVAC technicians can help prevent future issues from arising. They use their knowledge of AC systems to make adjustments and repairs that improve overall system performance and longevity.
Professional Repair Techniques
HVAC technicians use professional repair techniques to address the root cause of AC problems. They have the skills and experience to perform complex repairs safely and effectively, ensuring that your system operates efficiently.
System Optimization
In addition to fixing immediate issues, HVAC technicians optimize your AC system for better performance. They may recommend upgrades or adjustments that improve energy efficiency and cooling capacity, addressing the root cause of inefficiencies.
Trust Professionals for Your AC Repairs
While it may be tempting to do the AC repairs yourself, the complexity and potential hazards make it a task that is best left to professionals. You can ensure that your AC system is repaired safely and efficiently by relying on experienced technicians like those at Goettl Air Conditioning & Plumbing. Don’t hesitate to schedule an appointment for AC repair today to keep your home comfortable throughout the year.

What Our Customers Say About Us


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!







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.

...... 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 represented Goettl well.

We ended up needing a new unit. While I'm sure Goettl isn't the cheapest in town, for something at necessary as a good AC unit, you get 5 star service with your purchase. So far, we are happy with our choice.
Jorge didn't try to up-sell us. He was honest and realistic. If I could opt for him to come to every service call, I would. God Bless you Jorge!
12/2025: Andrew was AMAZING 👏 He is really knowledgeable. He took the time to explain what was going on with our heating system and spent extra time helping us out!

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.

December 2025: we just had our annual HVAC rejuvenation. Josue Diaz was a great technician. He checked all of the systems with a detailed list. When he noticed that we don’t have refrigerant locks on the outdoor unit he installed them free of charge.
Our most recent service with Goettl was a new HVAC system - Blake and Oscar were not only great at the technical parts of their job, but also at showing me some things I can do to help maintain the system between the regular maintenance that I have done through the Sadie Club membership. It is the little things that can make a huge difference, like leaving the box for the filter in a logical place so that I have a visual reminder of exactly what I need to order in 6 months. I could have taken a photo, but then I'd have to go find the photo.
Blake and Oscar were here for a long time installing the new system and checking that it worked. But honestly if it weren't for the drop cloths they put to protect my floors I probably could have forgotten they were here - they were so quiet and efficient. I had been expecting that it would be loud, but I could have worked from home with them installing and not have had an issue - if my daughter was still a baby I probably could have had her napping at almost any time of the process!
Overall, I could not be more impressed with the service I've had from this company and I look forward to working with them going forward to maintain my home and systems. And a quick note about the Sadie Club - they call you when the included maintenance is due - no more paying for something and forgetting to use it.

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!

Great person and great service visit.

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!

He left the work site clean and was very neat,I am completely impressed with Goettl
Technicians !!





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!
