Local service
Proudly serving Lockhart
Lockhart's housing stock includes older Victorian and Craftsman homes near the square, mid-century ranch houses on larger lots, and newer subdivisions along SH 130. The summer humidity here is high, and winter nights can drop below freezing, so systems need to handle both cooling and heating loads. The limestone bedrock close to the surface means ground loops for geothermal systems are rare, and most homes use slab foundations with ductwork in the attic. The town's spread-out layout means our crew drives longer distances between jobs, so we plan our routes carefully.
Our crew loads up in San Marcos and heads east on SH 80 or down I-10, carrying a full set of common parts and a range of filter sizes to handle the older homes' odd duct dimensions. We work on site, covering floors with ram board and using drop cloths in the attic access. We run a shop vac after every cut and bag all old metal and insulation. Because Lockhart is a straight shot from our base, we can get a second truck out for specialty parts without a long wait. We finish by running the system through a full cycle and cleaning up every scrap.

Local demand
What Lockhart homeowners call us for
AC Repair
Lockhart's humid summers cause coil corrosion and drain line clogs. We clear blockages, replace failed capacitors, and repair refrigerant leaks in attic units that are tight to reach.
Heating Repair
Freezing nights in Lockhart expose worn heat exchangers and igniters. We service gas furnaces and heat pumps, often working in crawlspaces under older homes with limited headroom.
AC Installation
Newer subdivisions near SH 130 need systems sized for open layouts and high ceilings. We install matched units, run new line sets, and seal ductwork to handle the local humidity without sweating.
Maintenance
Lockhart homeowners with older homes book seasonal tune-ups to catch small issues. We clean coils, check refrigerant pressures, lubricate motors, and test safety controls before the peak seasons hit.
Typical projects
The kind of work we take on in Lockhart
Evaporator Coil Replacement
We recover the refrigerant, cut out the old coil, and install a new one with a matching metering device. We braze the line set, pressure test, evacuate, and recharge to the factory charge.
Ductwork Modification
We cut and seal new supply runs to add cooling to a converted garage or addition. We tie the new duct into the existing trunk, insulate it, and test the airflow at each register.

Where we work
Across Lockhart
Downtown Lockhart
Historic homes near the courthouse square have original ductwork in tight chases and basements. We retrofit new equipment into existing spaces, often building custom plenums to fit the odd dimensions.
SH 130 Corridor
Newer subdivisions along this highway have standard attic installations with easy access. We work in spacious attics with pull-down stairs, and we often install high-efficiency units with variable-speed blowers.
Outlying Acreage
Homes on larger tracts east of town have long duct runs and septic systems. We route line sets through crawlspaces and seal duct joints to prevent air loss over the long runs to far rooms.
