AC Replacement in the Rio Grande Valley
There is a point where continuing to repair an air conditioner stops being the frugal choice. Knowing where that point is takes an honest look at the age of the equipment, what specifically failed, what the refrigerant situation is, and what the system has been costing to run.
A&A HVAC LLC gives you that picture in writing. If a repair is the right call, we will tell you so and make the repair. If the numbers favor replacement, we will show you why rather than simply asserting it.
Valley systems age faster than systems in most of the country. A compressor that would see 1,200 run hours a year in Dallas may see well over 3,000 here. That is why a 12 year old air conditioner in McAllen is often in the condition a 20 year old system would be elsewhere.
Symptoms to look for
- The system is more than 12 years old
- You have paid for two or more repairs in the past two years
- A technician has told you the compressor or a coil has failed
- Your system uses R-22 refrigerant, phased out of production in 2020
- Electric bills have climbed year over year with no change in usage
- Some rooms never get comfortable no matter what the thermostat says
- The house stays humid even when the temperature is right
- The system is noticeably louder than it used to be
Common problems we find
Failed compressor out of warranty
The compressor is the single most expensive component. Once it fails on a system past 10 years, the cost of replacing it usually approaches a meaningful fraction of a new system that carries a fresh warranty and much better efficiency.
R-22 refrigerant systems
Production and import of R-22 ended in 2020. Any remaining supply is reclaimed, limited, and expensive. A leaking R-22 system is a system on borrowed time no matter how good the rest of it looks.
Leaking evaporator coil
Coil corrosion is common here. Out of warranty, a coil replacement is a large enough repair that it deserves a side by side comparison against replacing the system.
Chronic humidity problems
A system that was oversized when it was installed will never control humidity well. Replacing it with correctly sized equipment fixes a comfort problem that no amount of repair work will.
Mismatched components from a past repair
A condenser replaced years ago and paired with the original indoor coil will underperform permanently. It is worth knowing that is what you have.

How we handle ac replacement
Assessment of the existing system
Age, refrigerant type, failure history, current condition, and measured performance. We want to know what you actually have before recommending anything.
The honest math
Repair cost, remaining expected life, and estimated operating cost versus replacement cost and its operating cost. If repair wins, we say so.
Load calculation for the replacement
Sizing is recalculated for the house as it is today, not copied from the old nameplate.
Options presented in writing
Several efficiency levels, real cost differences, warranty terms, and financing if you want it.
Installation and commissioning
Same standards as any new installation: matched equipment, deep vacuum, weighed in charge, verified airflow, new float switch and secondary pan, and a full walkthrough at the end.
When to repair and when to replace
Repair is the better value when
- The system is under 10 years old
- It uses R-410A or a current refrigerant
- The failure is a capacitor, contactor, motor, board, or drain issue
- This is the first significant repair the system has needed
- Repair cost is well under a third of replacement cost
Replacement is the better value when
- The compressor or a coil has failed out of warranty
- The system uses R-22
- The system is 12 years old or more and needs a major repair
- You have paid for multiple repairs in the last two years
- Bills are climbing and comfort has been poor for a while
Side by side
| System age | Minor failure (capacitor, motor, drain) | Major failure (compressor, coil) |
|---|---|---|
| Under 8 years | Repair | Repair, and check warranty coverage first |
| 8 to 12 years | Repair | Get both numbers. Replacement often wins on total cost. |
| Over 12 years | Repair if it is the first issue, but start planning | Replace |
| Any age, R-22 refrigerant | Repair only if the sealed system is not involved | Replace |
