When your AC stops keeping your home cool, it can quickly become more than an inconvenience, especially during San Diego’s warmer months. Whether it’s blowing warm air, running constantly, or making strange noises, deciding whether to repair or replace your air conditioner is a common dilemma for local homeowners.
At Anderson Plumbing, Heating & Air, we’ve helped families across San Diego County make informed decisions for over 45 years. Here’s how to know what’s right for your home.
AC Not Cooling? Here’s What to Know
It’s frustrating when your air conditioner [1] isn’t performing. In many cases, the issue could be something minor. But for older systems or units with recurring problems, replacement may be the more cost-effective option.
Understanding the cause of your cooling problem is the first step. A full system evaluation by a licensed HVAC technician can help you determine if a repair will fix the issue or if your unit is on its last legs.
Key Factors to Consider: Repair or Replace Your AC?
Several factors can help you decide between AC repair and replacement:
- System age: Most units last 10 to 15 years. Older systems are less efficient and more prone to failure.
- Breakdown frequency: Frequent repairs can indicate long-term reliability issues.
- Energy bills: Rising cooling costs may point to a loss in system efficiency.
- Comfort level: Uneven temperatures or excess humidity often signal deeper problems.
- Refrigerant type: Older units using R-22 refrigerant are more expensive to service and are being phased out.
When It Makes Sense to Repair Your AC
Not every problem means you need a new system. In these situations, a repair may be the smarter choice:
- The system is less than 10 years old
- The problem is minor, such as a faulty thermostat or capacitor
- Regular maintenance has been kept up over the years
- The cost of the repair is under 30 percent of a replacement
- The unit uses R-410A or another efficient refrigerant
If your air conditioner has generally performed well and the fix is affordable, it’s likely worth repairing.
Signs It’s Time to Replace Your Air Conditioner
Sometimes, repairing your AC is just putting off the inevitable. These are strong signs that it’s time to consider a replacement:
- Your unit is 12 to 15 years old or older
- You’ve made multiple repairs in recent years
- Energy bills keep increasing despite normal usage
- The system uses outdated R-22 refrigerant
- The home remains uncomfortable even when the system is running
- The repair estimate is over 50 percent of the cost to install a new system
Upgrading now can help you avoid repeated service calls and rising costs.
AC Repair vs Replacement: Cost Comparison
Here’s a general look at what you might expect in San Diego:
- AC repair costs: Range from $150 to $1,500 depending on the issue
- AC replacement cost: Typically, between $5,000 and $12,000, depending on the size and efficiency of the unit
While replacement costs more upfront, the long-term savings can be significant. Modern systems are more energy-efficient and can reduce your utility bills. California homeowners may also qualify for rebates or tax incentives when installing high-efficiency equipment.

FAQs About AC Repair and Replacement
How long does an air conditioner last in San Diego?
On average, central AC systems last 10 to 15 years with proper maintenance. Coastal areas may experience shorter lifespans due to salt exposure.
Can I just replace the outdoor AC unit?
It depends. The indoor and outdoor components need to be properly matched for safety and efficiency. Replacing one without the other can cause performance issues.
Are there rebates or tax credits for a new AC?
Yes. California offers several incentives for high-efficiency air conditioners, especially if you choose ENERGY STAR-rated models.
What’s the best time of year to replace an air conditioner?
Spring and fall are typically ideal. HVAC companies have more availability, and you may find better pricing before peak summer demand.
