HVAC Service in Onion Creek, Austin

Onion Creek starts far to the west, near Johnson City, and winds past Dripping Springs and Driftwood before it reaches southeast Austin on its way to the Colorado River. The neighborhood that shares its name opened in 1974 around the Onion Creek Club, designed by three-time Masters champion Jimmy Demaret. In 1978 the club hosted the first Legends of Golf, the event that helped inspire the Senior PGA Tour, formally founded two years later.

The community, about ten miles south of downtown, has since been absorbed into Austin. Downstream, the same creek pours over the limestone ledges at McKinney Falls State Park, open since 1976 and still one of the best places in the city to watch water move over rock after a good rain.

Onion Creek homes went up in waves from the 1970s onward, mostly one- and two-story houses on slab foundations with the ducts and air handler in the attic. Most are on their second or third system by now, but in the oldest sections many still breathe through the original duct runs, which are often undersized and leaky by today’s standards. Later additions hung off those runs may not get enough air.

Lots facing the fairways sit wide open to the afternoon sun, and west-facing glass drives up the cooling load late in the day. Streets closer to the creek sit lower and can hold humidity, so correct sizing and moisture control matter as much as raw cooling power.

When a system falls behind on a hot afternoon, our air conditioning repair service checks airflow and duct losses along with the equipment itself. On a 1970s or 1980s house, a new system bolted to the old ducts inherits their leaks, so sealing and resizing them can matter as much as the new equipment.

For heat, we repair and replace both heat pumps and furnaces through our heating department, and we can explain when a dual fuel heat pump makes sense for a home that already has gas. If replacement is on the table, build your system online to compare equipment before a technician visits.

Sunrooms, enclosed patios and converted garages are common in the older golf course homes, and they are often the least comfortable rooms in the house: lots of glass, and ducts that may never have been designed to reach them. A ductless mini-split heats and cools that one room without overworking the central system. Gold Eagle Services is a Mitsubishi Electric Diamond Contractor and installs them.

Onion Creek has flooded badly, most famously on October 31, 2013, when the creek crested at more than 40 feet, the highest since 1921, and more than 500 homes were damaged. Afterward, the city bought out hundreds of homes in the floodplain, and that land is now part of Onion Creek Metropolitan Park. If your equipment or ductwork was ever touched by floodwater, have it checked for corrosion and for mold in the air handler and ducts.

That is work we do: our indoor air quality services include duct inspection, cleaning and dehumidification, and our air quality index page tracks outdoor conditions. A Home Maintenance Plan adds spring and fall checkups so small problems get caught early.

The winners of that first Legends of Golf at Onion Creek Club, in 1978, were Sam Snead and Gardner Dickinson.

The creek has a longer history than the golf: a fossil skeleton of a mosasaur, a giant marine reptile from the time a shallow sea covered Texas, was found in the rocks of Onion Creek near McKinney Falls.
