My AC Is 10 Years Old. Is Repair Still a Viable Option?

If your air conditioner in Denver is pushing 10 years old, you might be wondering whether it’s worth repairing or if it’s time to invest in a new system. It’s a common dilemma for Denver homeowners, especially when summer heat rolls in and your AC starts showing signs of strain.

At Bell Plumbing, Heating, Cooling & Electrical, we’ve helped thousands of homeowners weigh the repair-vs-replace question—and we know there’s no one-size-fits-all answer. But we can help you make the smartest choice based on cost, efficiency, and your comfort needs.

How Long Does an AC Unit Last?

Most air conditioners are designed to last 10–15 years—but several factors affect that timeline:

• Frequency of maintenance
• How often the system runs (Colorado’s hot, dry summers = more wear)
• The unit’s efficiency rating (SEER)
• Proper installation and sizing at the time of purchase

If your AC unit has been well maintained, it might still have a few solid years left. But once you hit the 10-year mark, it’s worth keeping a closer eye on performance.

When Is AC Repair Still a Smart Option?

A 10-year-old AC doesn’t automatically need to be replaced. In some cases, a well-timed AC repair in Denver can keep your system running smoothly, especially if:

• It’s still cooling effectively without strange noises or smells
• The issue is minor (like a capacitor, relay, or thermostat)
• Repair costs are relatively low (typically under $500)
• It hasn’t needed frequent repairs in recent years

Our HVAC technicians always start with a full system diagnostic to determine whether a simple fix could get your system back in shape.

Signs It Might Be Time to Replace Your AC

While repairs can stretch your system’s life, there’s a tipping point where AC replacement in Denver makes more sense financially and practically. Here are the red flags:

• Frequent Breakdowns: If you’ve called for service more than once per season, those repair bills can add up fast.
• Rising Energy Bills: Older systems lose efficiency over time, especially if they use outdated refrigerants like R-22, which is now banned.
• Inconsistent Cooling or Poor Airflow: Hot spots in your home or weak airflow might indicate a compressor or blower motor issue—both costly to replace.
• Repair Costs Are 30%+ of a New System: If your repair bill is close to $1,000 or more, that money might be better put toward a new, energy-efficient unit.

AC Repair vs Replacement: The Cost Breakdown

Let’s say you’re facing a $700 repair bill on a 10-year-old unit:

• A basic replacement system might start around $4,500–$6,500
• Newer models come with higher SEER ratings, cutting energy costs by 20–40%
• You might also be eligible for tax credits or utility rebates on new high-efficiency systems

Long-term, a new unit can pay for itself in energy savings and peace of mind.
