Kyle, TX · Hays County
The house still has the system the builder installed
About 38% of Kyle's homes were built between 2000 and 2009 (Census ACS 2020–2024). In a house from those years that has never had its system replaced, the outdoor unit, the coil and the furnace or air handler are all the same age, and that age is now past twenty years.
The line is answered 24/7. Visits depend on which contractors are working your ZIP code.
Find the install year and the refrigerant
The data plate on the outdoor unit lists the model, the serial number and the refrigerant. The label inside the attic unit's panel lists its own. Some manufacturers print a build date; others encode it in the serial number. A permit sticker or the date on the electrical disconnect can help too.
R-22 or R-410A matters. Many systems installed before about 2010 run on R-22, which has not been produced since 2020. A leak in one of those is usually the end of the repair path. A system on R-410A can still be serviced and recharged.
Running is not the same as healthy
An original system can still cool. What changes with age is how it fails: compressors, attic coils and heat exchangers rather than capacitors and contactors. And because builders installed the same few models across whole streets, neighbors' experience is a reasonable preview of yours.
Replace before it fails, or wait
Waiting costs nothing until the failure, and then it costs choice: a replacement booked during an August heat wave is booked on the contractor's calendar, not yours. Replacing on your own schedule allows a second quote, a proper sizing, and a look at the attic ducts.
What a contractor should check on a visit
- Refrigerant charge and any sign of past recharges
- Compressor current and the condition of the outdoor coil
- The attic coil, drain pan and float switch
- On a gas furnace, the heat exchanger and combustion readings
- Airflow and the condition of the attic ducts
Common questions
Is replacing it now required by any rule? No. An existing system can keep running and be repaired.
