As summer winds down in Dallas, Mesquite, Fort Worth, and the surrounding areas, many homeowners start noticing their air conditioners showing signs of wear. After running almost nonstop during the Texas heat, your system may not be performing the way it used to. The big question is: should you repair your AC or replace it altogether?

At LTX Air Services, we hear this question from homeowners all the time. The truth is the right answer depends on your system’s age, condition, and performance. In this guide, we’ll break down the factors that help you decide whether AC repair or AC replacement is the smarter move.

Signs Your AC Might Just Need a Repair

Not every issue means you need to replace your system. In fact, many problems can be fixed quickly with the right repair. Here are common signs that point toward a repair instead of replacement:

• Your AC is under 10 years old – Most systems are designed to last 12–15 years with proper AC maintenance. If yours is still on the younger side, repairing usually makes sense.

• It’s still cooling your home – If the airflow feels strong and the temperature is right, small issues like clogged filters, refrigerant leaks, or a faulty capacitor might be the culprit.

• Your energy bills haven’t spiked dramatically – If your bills are consistent but your system just isn’t cooling like it should, a tune-up or part replacement could solve the issue.

• The repair is minor – Issues like replacing a thermostat, fixing an electrical connection, or swapping out a capacitor are usually affordable and quick.

Signs It’s Time to Replace Your AC

On the other hand, there are situations where replacing your AC is the smarter financial choice. If you notice these signs, it may be time to upgrade:

• Your AC is 12+ years old – Older systems lose efficiency and are more prone to costly breakdowns.

• Frequent repairs – If you’re calling for service multiple times a year, replacement is more cost-effective long term.

• High energy bills – Aging systems use more energy, especially after a long Texas summer. A new high-efficiency AC installation can cut cooling costs significantly.

• Uneven cooling – If some rooms feel hot while others are freezing, it could mean your system no longer has the capacity to cool your home properly.

• Major repair costs – If the repair cost is close to half the price of a new unit, replacement is usually the best choice.

👉 Pro tip from LTX Air Services: A new, energy-efficient system can save Dallas–Fort Worth homeowners up to 30% on monthly energy bills. That adds up quickly in our Texas summers.

Repair vs. Replace: The 50% Rule

A common guideline in the HVAC industry is the 50% rule:

• If your AC repair costs are less than 50% of the price of a new unit and your system is under 10 years old, repair is usually the way to go.

• If the repair costs are more than 50% of a replacement, or your AC is over 12 years old, replacement is the smarter long-term investment.

The End of Summer is the Best Time to Decide

Late summer and early fall are actually the perfect times to address AC issues in Dallas, Mesquite, and Fort Worth. Why?

• Contractor availability – HVAC companies are less busy than peak summer, so scheduling is easier.

• Seasonal promotions – Many manufacturers and installers offer deals on new units during this time.

• Preparation for next year – Fixing or replacing your AC now ensures you’re not scrambling when the next heatwave hits.
