Installation or Repair? How to Decide the Best Path for Your AC

When your air conditioner starts acting up, you’re faced with an important — and often stressful — decision: Should you repair the system or replace it entirely?
Choosing the right path can save you thousands of dollars, improve your home’s comfort, and even lower your energy bills. But how do you know when a repair will do the trick or when it’s time to invest in a new unit?
Let’s break it down step-by-step so you can make the best decision for your home and budget.

1. Consider the Age of Your AC Unit

One of the first things to think about is the age of your air conditioner.

• Less than 10 years old? A repair often makes sense.
• More than 10–15 years old? Replacement might be the smarter long-term move.

Older systems are less efficient and more prone to frequent breakdowns. Plus, newer models are designed to be more energy-efficient, meaning lower utility bills for you.

2. Evaluate the Cost of Repairs

A simple rule many HVAC experts use is the $5,000 rule:
Multiply the cost of the repair by the age of your unit.

• If the result is less than $5,000, repairing could be worth it.
• If it’s more than $5,000, replacement usually makes more financial sense.

Example:
If your AC is 12 years old and the repair will cost $400 → 12 x 400 = $4,800 → Repair might still be acceptable, but if the repair were $500 or more, replacement would be a safer bet.

3. Review Your Unit’s Efficiency

Even if your AC is working, it may be costing you a lot in energy bills.
Older units typically have a lower SEER (Seasonal Energy Efficiency Ratio) rating. Today’s systems offer SEER ratings of 14 and above, significantly cutting cooling costs.

Signs your system is inefficient:

• Unusually high electric bills
• Long run times to cool your home
• Hot or cold spots in different rooms

If your system struggles to keep up, upgrading to a modern, energy-efficient unit could pay off quickly.

4. Frequency of Breakdowns

How often do you call your AC technician?

• One minor issue in a few years: Repair makes sense.
• Frequent repairs, strange noises, refrigerant leaks, or complete shutdowns: It’s time to consider replacement.

Frequent service calls add up, and constantly patching a failing system only delays the inevitable.

5. Comfort Level in Your Home

Even if your AC technically still runs, is it truly doing its job?

• Are some rooms hotter or colder than others?
• Does your home feel humid even with the AC on?
• Are you constantly adjusting the thermostat?

If your system can’t keep your home comfortable, a new installation might be the better choice for your peace of mind.

6. Availability of Parts

As AC units age, it becomes harder (and more expensive) to find replacement parts.
If your technician struggles to find components or warns you that parts are obsolete, it’s usually a sign that upgrading will be more practical and cost-effective.

Final Thoughts: Trust the Experts to Guide You

Deciding between AC repair and replacement isn’t always clear-cut. It often depends on a combination of the unit’s age, the repair cost, overall efficiency, and how comfortable your home feels.
If you’re unsure about the right move for your situation, it’s smart to get a professional assessment.
