When to Repair or Replace Your Air Conditioning System: Key Factors to Consider
Your air conditioning system can be costly, but it’s a huge investment in your home’s comfort and energy efficiency. Yet, with proper care and maintenance, your air conditioner can last a good 10 to 15 years, depending on the model.
However, as your system ages, it may develop problems ranging from minor repairs to components you need to replace. As the repair bills stack up, you may wonder if repairing or replacing your system is more cost-effective. Here are some key considerations to make the best decision for your home and wallet.

Your AC Unit’s Age
With proper care, an air conditioner’s lifespan is between 10 and 15 years. Routine maintenance, at least once a year, can keep your unit running efficiently and maximize its lifespan. While you may have a warranty, they typically expire after two years.
However, your AC will age beyond what routine maintenance can fix at some point. If your unit is 11 years old or older and you’re experiencing frequent problems, it may be best to upgrade your system.
If your AC unit is less than 11 years old and well maintained, a repair may extend its life a few more years.
The Extent of Repairs
No matter how well you care for your unit, it will experience some wear and tear over the course of a cooling season—particularly in hot climates like the Southwest. AC units that constantly run and sustain cooler temperatures throughout the day and night undergo more stress than units that are only used occasionally, leading to more frequent repairs. Some repairs are minor, while others may be extensive and pricey.
The repair is the best choice if you need minor repairs, such as loose, cracked, or broken ductwork, a clogged drain line, or an electrical problem like faulty wiring. You can enjoy your system for years to come for just a small investment.
However, major repairs, such as a damaged blower motor, compressor, or condenser coil, can quickly add up. Extensive repairs to these components may warrant an upgrade rather than a repair.
The Cost of Repairs
If you have a newer unit that needs repairs—even expensive ones—it doesn’t make financial sense to upgrade to a new one. For a few hundred dollars, you could fix the problem and enjoy your AC unit for the better part of a decade or longer.
However, some repairs can meet or exceed the cost of a new unit. That’s when it makes sense to evaluate your options. A good rule to follow is to get the repair if it is less than 50% of the cost of a new unit and still under warranty. If it’s more than 50% of the cost of a new unit, consider upgrading.

The Efficiency of the Unit
The efficiency of your AC should be a major factor in your decision to repair or replace it. Older units are inefficient for several reasons, including outdated technology, the toll of age, and wear and tear. Even with unused units, the newer model will be much more energy efficient than an older model, leading to more savings on your energy costs.
How can you tell if an AC system is efficient? AC energy efficiency is measured by the Seasonal Energy Efficiency Ratio (SEER) rating. As of 2023, new air conditioners must have a SEER rating of at least 14 in the northern states and a SEER rating of 15 in the southern states. If your older air conditioner has a SEER rating under 10, consider replacing it with something more efficient. An upgrade from SEER 9 to SEER 14 can reduce your energy consumption by more than 35%.
Another feature to look for is the ENERGY STAR® certification. The Environmental Protection Agency (EPA) established this program in 1992 to promote more energy-efficient products, including air conditioning. If a product has the ENERGY STAR® logo, it’s recognized for its category’s highest level of efficiency.
The Frequency of Repairs
Repairs for an aging AC unit can be costly and frequent, disrupting your home routine and putting a dent in your wallet. If you’re dealing with a new problem seemingly every time you finish fixing another, there’s less expense and hassle if you spring for a new unit.
Generally, two or fewer repairs over the past 10 years are normal and reasonable. If you have experienced three or more repairs over the past 10 years, your system is rapidly declining and should be replaced.
The Size of the Unit
The size of your AC unit greatly impacts your home’s comfort and energy costs. Some homeowners mistakenly believe getting a bigger unit will keep their home cooler and more comfortable, but that’s far from the truth.
When you have an oversized AC unit, it has to cycle on and off more frequently to reach your desired temperature, called “short cycling.” This not only strains the system and increases your energy bills, but each cycle is incomplete. The unit can’t remove the humidity from the space, leading to condensation and a muggy feeling.
Conversely, an undersized unit has to work much harder than it should to cool your home. This increases the stress and wear and tear over time, leading to a shortened lifespan, frequent repairs, and a possible premature breakdown.
If your system isn’t the proper size for your home, it’s best to upgrade it. The upfront cost will pay off in better cooling, fewer repair bills, more efficiency, and lower energy costs over the unit’s lifetime.
Tax Incentives for Energy-Efficient AC Upgrades

If you’re considering a new air-conditioning system, there’s no better time than now. Under the Inflation Reduction Act (IRA), the federal government incentivizes energy-efficient home improvements by offering tax credits for qualifying upgrades under the 25C program.
While the tax credit can vary, you may be eligible for up to 30% of the project cost—up to $600 maximum—for high-efficiency air-conditioning upgrades. Be sure to discuss your eligibility and incentives with a tax professional.
Learn more about the IRA and 25C incentives.
Is It Time for an Upgrade?
It can be challenging to decide whether to upgrade your air-conditioning system instead of paying for repairs. While these guidelines can help, it’s best to consult a trusted HVAC technician to evaluate your system’s condition and walk you through all your options, including repair and replacement options that will work best for your home, family, and budget.

We had Edgar come out to inspect our new home today and he did a very thorough inspection. He made sure the unit was checked so when the warranty company comes out we have all information possible. Amazing customer service and very personable
Edgar came back after a warranty inspection was done on the home by the install company. He found errors and was amazing at documentation of the issues. If I could give more than 5 stars I would.
Peter and Josue came out today to do an additional check on our unit with humidity issues. The weather was not conducive to having the outdoor pressures checked and they were very thorough with an interior check. Very professional and knowledgeable.
Tyler b was very professional today and gave great recommendations for upkeep of our unit in



Highly recommend Goettl


They had the right solution in my time of need. I'll be returning for future services, no doubt.








He was my technician from another company. I’m always happy with his service that’s why I’m following him.
Thank you Colby , you are the best technician I’ve ever had .
I really do appreciate your work!!


He arrived promptly and was very professional.
We are first time customers and from now on we are calling Goettl for all our plumbing needs.
Thank You.



Andrew came in and unclogged the bathroom sink and cleared out the line . We used the Smart Sadie program for it.
Thanks Andrew and Ian and Goettl!








Overall, an awesome tech. I would love for him to be my designated technician for any future service calls for my AC unit. Thank you for a wonderful experience!


I’m very happy with the seamless experience.



Frank did an excellent job at explaining every thing in terms that were understandable to both myself and my wife. This greatly assisted in making the right decision to look at all options on either repair or update/purchase for the future and in the long term, saving money.
Jose Carreon was the tech who was dispatched to look into a problem of a brand new system not working correctly after a new install. Jose was very methodical in his approach and found the actual issue which was not an install issue except the settings of the thermostats which were replaced and installed by Goettl. Jose's complete inspection and patience resolved the problem and he went the extra mile of calling a supervisor for a second opinion. The system is now running as it should!!! Thanks Jose!!


Great communication





Call Goettl and was able to get us on the schedule due to a cancellation they had.
Jef Eusepi our tech was fantastic.
He explained everything and showed us pictures of what he was doing and fixing.
Would definitely recommend this Company and Jef.


I am very thankful for their help today.







Thanks Goettl and more importantly, thanks Blair!

Update: 12/3/24 - Jacob is great. He fixed the leaking parts on water softener and also checked the water heater to see what can be done with that. He is efficient and very knowledgeable and reviews everything so you understand.

Update: 7/25/24 - had some more work done today. The folks who come to service, install, etc. are great. They know their job, are very efficient and friendly. Today it was Justin and Luis who were installing a new filter system. Looking forward to not have to change filters every month. Thank you, gentlemen, for all the hard work in the heat.
‐----‐-----------------------------
They said I needed to replace my a/c. I was given a choice of 5 units. I liked that the 2nd most expensive would balance the temperature in my house. I get full west in my living room in the afternoon. It is always 10 plus degrees hotter on my sofa, than rest of house. So I paid a fortune and it isn't doing what he said it would. They came back and added another vent to my living room. Better, but still not what I was told. I could saved $10k and got the cheaper model. Don't think I have much recourse to get this fixed. The technicians are very good, too bad their salesmen and products are not up to the same standard.













Thank you Ian for my maintenance today!
March 2, 2024

A special shout-out goes to Pablo, our technician. He was on time, friendly, and extremely knowledgeable.

Highly recommend Goettl HVAC—and if you can, ask for Pablo!

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.


He was knowledgeable and friendly and was able to flush the tank and get my hot water flowing again. Thanks again...




















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.


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.

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.
