How a call from here works

1. Say what the system is doing Not cooling, not heating, iced lines, water at the attic unit, a breaker that trips. Add the thermostat setting and what the house actually reads.

2. A contractor is matched by ZIP code The line routes the call to an independent heating and cooling contractor taking work in that ZIP code. Coverage shifts during the day; a match is not promised.

3. Visit, findings and figure come from that contractor The contractor books the visit, diagnoses the system and quotes any repair or replacement. This site sets no figures and sends nobody.

Mountain City is the exception in this corner of Hays County. Its homes are older, with a median build year of 1986, and almost all of them heat with electricity (Census ACS 2020–2024). That means systems on their second or third replacement, and heat pumps or electric strips rather than gas furnaces.

A small, older, owner-occupied town

Mountain City sits along FM 2770 between Buda and Kyle, with most of its land in the 78610 ZIP code and a smaller part in 78640 (Census 2020 relationship file). It has fewer than 300 occupied homes in the Census estimate, so its figures carry wide margins of error, but the shape is unusual: nearly every home is a detached single-family house, nearly all are owner-occupied, and most were built in the 1980s. Very little was built after 2000.

What that means for the system

The house is older than the system. A home from the 1980s has almost certainly replaced its original equipment at least once, and maybe twice. The age of the house says little; the install year on the outdoor data plate says what matters.

Electric heat. About nine in ten households heat with electricity. A heat pump or an air handler with electric strips is the norm. A heat pump that lives on its strips in winter, or an older straight AC with strips that could be replaced by a heat pump, are common conversations here.

Refrigerant. A system replaced in the 2000s may still be on R-22, which has not been produced since 2020. One replaced in the 2010s is on R-410A. New equipment since January 2025 ships with R-454B or R-32.

Ducts in an older house

Ducts in a 1980s house may be original, or replaced along with one of the systems. Older ducts can be leaky or undersized for the current system. If rooms run hot or the system runs long, attic ductwork is worth checking before blaming the equipment.
