Should I Repair or Replace My Air Conditioner?
Every homeowner in the Dallas area eventually reaches a point where they must decide whether to repair their current air conditioner or replace it with a new AC system. Choosing wrong can cost more than you expect, so how do you make the best decision for your home, your comfort, and your budget? Start by answering a few key questions.
Signs It May Be Time for a Replacement
Ice buildup is a major sign that replacement or repair may be needed
Ask yourself:
- Is your system more than 10 years old?
- Does your home feel less comfortable than it used to?
- Are certain rooms hotter or colder than others?
- Do you hear unusual noises or smell strange odors?
- Have your energy bills gone up?
- Is ice forming on your outdoor condenser?
If one or more of these feels familiar, you are right to consider whether repairing or replacing is the smarter move.
How Long Should an AC System Last in Texas?
Air conditioners in the DFW area work harder than systems in many parts of the country.
We experience:
- 234 sunny days every year
- More than 100 days above 90 degrees
- Extended periods of heat and humidity
With those conditions, most air conditioners in Plano, Fairview, or anywhere in DFW last 10 to 15 years when properly maintained. Even the most reliable systems eventually struggle to keep up.
How Often Does Your System Need Repair?
Yes, almost any AC system can be repaired. The better question is whether those repairs still make financial sense.
Consider the pattern:
- One repair this year
- Another next year
- A major failure the year after
Older systems lose efficiency, run longer, and cost more to cool your home. If AC repair has become an annual event, it is time to evaluate new options and compare long-term value rather than focusing only on the immediate fix.

One major repair can cost as much as the down payment on a new unit.
Does Your System Still Use R-22 Freon?
R22 refrigerant is phased out and R410A systems are following
If your air conditioner is more than 12 to 15 years old, it may still use R-22 refrigerant, also known as Freon. R-22 was phased out starting in 2020 because of environmental concerns. Supplies continue to shrink, and repair costs rise as reclaimable R-22 becomes harder to find.
What About R 410A?
Systems built after R-22 typically run on R-410A. This refrigerant is still legal to use, but federal regulations are phasing down production due to its higher global warming potential. Over time, R 410A is expected to become more expensive.
A2L Refrigerants Become Standard January 1, 2025
As of January 1, 2025, all newly manufactured residential AC systems must use A2L refrigerants such as R32 or R454B. These newer refrigerants:
- Have a lower environmental impact
- Offer higher energy efficiency
- They are not classified as Freon
- Cannot be used in older R-22 or R-410A systems
A2L refrigerants operate differently, and older equipment cannot be retrofitted without risking damage or safety issues.
What This Means for Homeowners
If your AC uses R-22, replacement is usually your best long-term choice
If your system uses R-410A, repairs are still possible, but could grow more expensive over time
New systems run A2L, are more eco-friendly, and help future-proof your home
Homeowners across Frisco, Lewisville, and Highland Park are choosing replacement simply because the refrigerant market is heading in that direction.

A: Most units last 10 to 15 years, depending on usage, maintenance, and heat exposure.
Q: Is repairing an older AC still worth it?
A: A repair may make sense for newer systems, but frequent breakdowns mean replacement can save more money long term.
