AC Repair and HVAC Service in Manchaca, TX

Manchaca (say MAN-shak) grew up around springs on the old road to San Antonio. An early owner of the springs, Washington D. Miller, later served as Sam Houston’s private secretary. In 1852 he sold them to Adolphus Weir, who ran a stagecoach stop there, and after the International-Great Northern Railroad arrived in 1880, the settlement shipped cotton, grain and lumber. Today it is an unincorporated community about 12 miles southwest of downtown Austin, strung along FM 1626 and Manchaca Road. The houses run from twice-remodeled ranch homes on big, shaded lots with a shop out back to newer slab homes in subdivisions, and the questions we get from Manchaca follow the same split.

Because each remodel stretched the old ducts instead of redesigning them. The newest rooms end up at the end of the longest, thinnest runs, and every patched connection is one more place for cool air to leak into the attic. We measure airflow room by room before deciding whether to reroute, resize or seal. If the equipment itself has failed, our AC repair technicians find the cause and give you a repair price and a replacement option side by side.

Not ducts. A duct run across the yard loses too much of what it carries before it reaches the shop. For shops, studios and guest houses on Manchaca’s larger lots, a ductless mini-split is usually the answer, because it needs only refrigerant lines and power. We’re a Mitsubishi Electric Diamond Contractor, and the ductless mini-split systems we install heat the shop in January and cool it in August.

Maybe, but not because of age alone. Plenty of older Manchaca homes still run furnaces that went in a long time ago. What decides it is the condition of the heat exchanger, burners, venting and safety controls, so that is what we inspect. Our heating services cover repair, furnace replacement and tune-ups, and if your home has gas, a new furnace can pair with a heat pump in a dual fuel setup.

Start online, on your own time. Build your own system on our website to see the equipment choices, then we confirm sizing with a load calculation at the house. In the newer slab homes in Manchaca subdivisions, where the air handler usually sits in the attic, sealed ducts and correct sizing matter as much as the brand on the box.

Some. Oaks drop leaves, tassels and pollen onto the outdoor coil, and a matted coil makes the system work harder for the same cooling. A spring coil cleaning clears it. Pollen also slips inside through leaky return ducts, which is why our indoor air quality services include duct sealing and better filtration. Our AQI page shows current Austin air conditions.

Our Home Maintenance Plan brings two visits a year: cooling in spring, heating in fall. Each covers coil cleaning, drain line checks, electrical tests and a look at refrigerant levels. In a yard full of oaks, the coil cleaning alone earns its keep.

The name is usually traced to José Antonio Menchaca, a Tejano army officer, which is why you will see the road spelled both ways.

In October 2018 the Austin City Council voted to change the city’s stretch of Manchaca Road to Menchaca Road, the historic spelling. After a court fight, the new signs went up.
