Your Spring AC Maintenance Checklist – What to Look for
It’s time for some spring cleaning. Time to deep clean the carpets and rugs. Clear out junk from your attic, basement, or garage. Wipe down the ceiling and wash the windows.
But what about your AC system?
There are many benefits to adding your AC system to your spring cleaning checklist. By doing some simple maintenance tasks, you’ll boost your system’s efficiency, which will help save on your monthly energy costs.
However, the greater benefit is to the longevity of your air conditioning. Keeping up with maintenance is the best way to get the most out of your AC system for as long as possible. By regularly servicing your AC, you’ll extend your system’s lifespan in the long term while improving the air quality inside your home in the short term.
Spring is the best time to perform these simple maintenance tasks, before your AC begins running at full capacity to keep you cool throughout the height of summer. This is key, because beside boosting performance, you may also catch smaller issues with your AC before they become larger, more expensive problems later.
Intense summer heat strains your system, which will exacerbate small problems quickly, and make the time waiting for repairs all the more uncomfortable. Here’s our complete checklist to make sure your system is ready for hot days of summer..
Spring AC Maintenance Guide
- Replace Your AC Filters: This is an easy task to do that will make an enormous difference. While you really should be replacing your filter every 90 days or so, if it’s slipped your mind, then there’s no time like the present. A new filter will not only improve your air quality and boost efficiency, but it’ll prevent your AC system from straining, thus reducing wear and tear, and avoiding damage.
- Clean Out Vents and Vent Covers: This is another simple way to make an impact on your home’s air quality and comfort. Over time, lint, dander, and other particulates will get caught as they flow through the air vents, building up and impeding air flow. To reduce blockage, remove your vent covers and clean them off using a brush or rag. You can also use a broom or brush to sweep out dust and lint from the air duct walls. Finally, make sure no furniture is blocking the vents, which can affect cooling throughout the room. If you’re experiencing an exceptional amount of dust or buildup, consider a professional duct cleaning.
- Test the Thermostat: First, ensure that it is on and working. Is the display dim or inconsistent? If so, you may need to replace the battery or check for loose wiring. Next,set your thermostat low, then walk around your home. Did your AC unit kick on? Is air flowing equally into each room? Does each room feel the same temperature? If not, you may need a professional to inspect your system. If you’re feeling like your thermostat isn’t accurate, a simple indoor thermometer (which can be bought at your local hardware store for somewhere between $10-20) can help see any discrepancies. If it’s off, then it’s time to call in help
NOTE: if your AC is in a difficult to reach spot — like your roof — consider having an HVAC tech perform these next checklist items.
- Check for Unusual Noises in the AC Unit: Put an ear to your AC unit while it’s running and listen for any rattling, squeaking, or creaking. A strange noise (or smell) coming from your AC unit could mean a loose or damaged part that needs repair or replacement by a professional.
- Clean and inspect the condenser unit: A dirty outdoor condenser unit can’t efficiently pull heat from your home, meaning it needs to work overtime. Much like changing the oil on your car, this is one of those things that you can do yourself but might want to have done by a professional for ease and safety. For the more handy, this cleaning can be done with a soft brush and hose (remember to brush and spray downward across the fins and slats, not in), but if you’re unsure, call in some ac maintenance help. While you’re out there checking the unit, cut away any vines, branches, or plants growing on or near the housing that may block the intake.
- Check the Evaporator Coil: Over time, the evaporator coil (located near the blower) may accumulate dirt, or start to grow mold due to the moisture, which will limit its effectiveness, shorten your AC’s lifespan, and affect your indoor air quality. If you do find dust or mold on your evaporator coil, we recommend calling a professional to clean it rather than attempting it yourself.
- Clean Out the Condensate Drain Line: The growth of algae or mold can block your condensate drain line. If the line becomes clogged and backs up, it can cause water damage or a system shutdown. If your condensate drain line is clogged or dirty, you can flush the line using either a vinegar solution or store-bought cleaner.
By going through this checklist, you’ll have your AC ready to keep you cool throughout the spring, summer, and into the fall. However, there are a few maintenance or repair issues, such as cleaning off your AC unit’s condenser coil or repairing bent fins, that we do recommend hiring a professional for..
Professional AC Maintenance Checklist
While scheduling an AC maintenance check with a professional costs more than DIY spring cleaning, you do get what you pay for, and that value can translate into greater savings down the line. Experienced HVAC professionals, such as the ones at Goettl, will be able to more thoroughly inspect and service your AC unit, ensuring top performance while maintaining safety.
Whether or not you use Goettl’s services, it’s helpful to know what to look for when having your AC serviced. When you schedule an AC maintenance inspection with a professional, you should expect them to do the following:
- Inspect blower assembly, motor, and capacitor.
- Clean the outdoor condenser coil.
- Check compressor amps, starting and running.
- Check combustion blower housing for lint and debris and clean as necessary.
- Inspect evaporator coil, drain pan, and condensate drain lines.
- Check air filters.
- Inspect conditioned airflow system (ductwork) and check for leaks.
While Your System is Operating
- Monitor system starting characteristics and capabilities.
- Listen for abnormal noise.
- Search for sources of unusual odors.
- Monitor air conditioning and heat pump systems for correct refrigerant charge.
- Monitor gas furnace manifold gas pressure and adjust as needed.
- Check vent systems for proper operation.
- Monitor system for correct line and load volts/amps.
- Monitor system operation per manufacturer’s specifications.
System-wide Inspection
- Inspect and tighten all electrical connections and terminals.
- Ensure correct supply voltage at rest, start, and run.
- Build up on internal components, like heating coils or dishwasher arms.
- Clean, level, and calibrate thermostat. Set the thermostat heat anticipator.
- Examine the complete system for code violations and possible safety problems.
- Advise on other ways to reduce energy consumption, improve safety and enhance comfort.
- Complete and present full written report.
Goettl’s always looking for how to go above and beyond when it comes to our customers, which is why we have such high standards for our air conditioning maintenance. If your air conditioning professional doesn’t follow these guidelines, they might be missing key components of your system’s health.
Keep your AC Healthy All Year Round
If your AC unit’s been running for a couple of years or needs a little more TLC than a simple spring cleaning can provide, we recommend scheduling Goettl’s all-inclusive Rejuuuvination® AC maintenance service. Our Rejuuuvination® AC maintenance service is a combination AC tune up and system overhaul that will have your air conditioning running at maximum performance.
For ongoing performance upkeep, we also offer our Smart Sadie membership program.

Both you and Goettl will be alerted if your efficiency begins to drop, and we’ll be at the ready should anything need to be repaired.
So, this spring, go ahead and add your AC unit onto your spring cleaning checklist. You’ll boost your AC’s efficiency, and your household comfort, while staying worry free throughout the summer.

What Our Customers Say About Us


His experience led us to a solution for our pipes, which saved us thousands and thousands of dollars.
He’s a good man to have on your side



Edit: I was contacted by the branch manager and she accepted full responsibility and was very upfront. They made up for it in kind and I appreciate them being upfront and willing to make the situation right. Their customer service is top notch!


The service was perfect. The technician Julian Bray was pleasant, knowledgeable and completed the install quickly. The area was left cleaner than when he arrived.


The leads Nick & Brian were knowledgeable and covered our floors to protect them. Their crew included Kevin & Ricky who were also kind and respectful.

As always they came thru and did an excellent job Damian Palazeulos was very meticulous and skilled.






Installer Tech Ardian and his assistant arrived on schedule this morning and have completed the job that needed to be done orderly and neatly. Thanks everyone.


Junior Gonzalez (Goettl) came the next evening, replaced my wall inlet valve and began the reinstallation. He found that the flange did indeed need to be replaced, but that required soldering due to my older house’s lead pipes.
Richard Wenzlaff (also with Goettl) came the next day and finished the installation (including soldering pipe repair and flange installation).
Great people. Very courteous and patient. Very thorough: they checked water pressure and dbl checked their jobs. Would recommend and call again.

Jesus was are tec came in check everything let me know what would need to be done or taken care of came in respectfully with a great attitude

Thank you David for a job well done.

Johnthan, Thank you so very much for conducting the plumbing assessment of my home this morning. Your professionalism, expertise and personal demeanor were outstanding. Your patience, knowledge and customer educational skills were greatly appreciated, and I am a much better informed customer when it comes to the status, potential issues and how to resolve any water/ plumbing related issues that may arise in the future.
Again, thank you.
Abdiel Chavez, technician came out today to perform my heating system check. He was very professional and thorough in his assessment. It was a pleasure seeing him again as he was the initial technician to come to my home when I first moved here, so it was like having a visit from an old friend. Thank you Abdiel.











Damian was wonderful. He is a great asset to the Goettl team. Thank you for quick, reliable service.




...... 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.



Elvin did a professional job, very satisfied with his work.and he had the time to explain everything to me.thank you






Update: Jeremy Ortega was awesome did a great job taking care of us and our unit !! Informed of prevention and ways to keep our system healthy highly recommend!!


Parker has a lot of knowledge and doesn't hide anything, or even treat me like I may not know what I'm looking at. I really appreciate everything he has done today, his hard work, and his kind heart. I will be requesting him going forward.

We couldn’t be happier with his service and recommendations. We were very happy with the fast service and the excellent team installing our unit! They were installing the new unit the next day and they were very professional and did an excellent job!
Thank you for all for the quality and excellent service and advice!
Bruce Spears and Donna



Had Andrew come out to remove garbage disposal and repipe sink. He also swapped out 13 emergency water shut off valves in 3 bathrooms.
Andrew was professional, courteous and expedient. He did have to run out to get some supplies. He stayed until 7pm to complete the job on one trip.
May 2023 update. Technician Steve came today to do the summer rejuvenation. Friendly and professional tech. Explained the process and findings. Both systems are new, so everything checked out good. Did a god cleaning of coils and now all set for the summer season. Had them out for fall prevention service and to review the systems that are here. I just bought the house and needed to understand what was in place.
The service tech, Kevin was very knowledgeable, friendly and professional. He explained and provided photos and video of all components. He ensured keeping house clean and wore booties.
My second unit is not in the best shape, and Kevin explained each of the issues. I will follow up with service managér to determine next steps (repair or replacement).
I signed up for there service plan and am very pleased with the service and communication to date
12/21 Luis C came today to do routine maintenance on hot water heater. Professional and courteous. He did a through job and explained everything.
10/15. Juan came today and did a great job. He was professional, courteous and friendly. Was here for exterior water bid but also did a hot water heater. Took his time and explained everything.










If there was a 6th star, he’d be getting it!










Thank you Preston








Professional, knowledgeable and efficient. Very polite and courteous
Also installed surge protectors on the the condensers






We’ve been Goettl customers for years and have always appreciated their service, but Kevin Edwards truly raised the bar. During his visit yesterday, Kevin showed outstanding attention to detail and technical expertise. He thoroughly inspected every part of our HVAC system, documenting his findings with photos and clearly explaining issues that had gone unnoticed through several previous service visits.
Kevin discovered that our HVAC system had been improperly installed when the home was built—something no other technician had identified. He explained how that flaw had created a chain of problems affecting the furnace, cooling system, and overall efficiency. Because the system uses an outdated refrigerant, repairs weren’t a viable long-term solution, and Kevin guided us toward a responsible upgrade plan.
While no homeowner wants to replace a system after only seven years, we’re grateful Kevin uncovered these hidden issues before they caused a catastrophic failure. His thoroughness, honesty, and professionalism turned a potential headache into peace of mind. Kevin is an exceptional representative of Goettl, and we recommend him without hesitation.

I want to express my complete satisfaction with the work performed by Frank Piusseaux, a technician from Goettl.
For months, several technicians tried to identify the issue with my air conditioning unit, but no one could solve it. However, from the moment Frank arrived, he showed great professionalism and dedication. He took the time to carefully investigate the cause of the problem and determined that the issue was a short circuit in the wiring between the thermostat and the unit.
Thanks to his knowledge and effort, my air conditioning system is now working perfectly.
I truly hope that Goettl recognizes the value of having such a skilled, responsible, and committed employee. Technicians like him make a real difference and deserve special recognition, even a financial incentive, for the value they bring to the company.
Thank you very much, Frank, for your excellent work!










Great service great company. Will definitely be using for future HVAC needs.


Great communication.
Explained everything in detail.
Took before and after pictures.











I called Goettl and set up an appointment.
Mike H arrived on time and with his extreme knowledge and experience, he was able to replace the tank and give my system a much needed flush. Mike was so courteous and polite and answered all my questions and gave me advice on the how and why this happened and how to avoid this in the future.
Thank you Goettl and thank you Mike!




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.
Ralph & Kathy Lesmeister



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.




Now we have a new flange, installed correctly, and ready for the new toilet!








The company is installing a tankless heater and the customer service is outstanding.
I recommend Geottl to all!

I definitely recommend Goettl for all your needs.

Nick was helpful, friendly and professional in scheduling the appointment around my commitments.
I have used Goettl for nearly 20 years for my plumbing and HVAC needs. I recommend them as reliable, professional and easy to work with.


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!

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.
