Case Studies
Documented challenges, solutions, and outcomes from real projects.
High-Efficiency AC Installation in Hyde Park Bungalow
Hyde Park, TX
A 1920s Hyde Park bungalow received a new high-efficiency central air conditioning system designed around the home's original ductwork layout.
Outcome: Indoor temperatures now hold steady within one degree of the thermostat setting even during August afternoons, and the homeowners retired all three window units. Static pressure readings came in well under the manufacturer's recommended maximum, which should extend blower life and reduce energy use. The homeowner noted the equipment is noticeably quieter than the window units and that the historic interior trim was left fully intact.
Furnace Repair Restores Heat to Mueller Family Home
Mueller, TX
A failed igniter and cracked flame sensor left a Mueller family without heat during an unseasonably cold January week.
Outcome: The furnace returned to steady operation with clean combustion readings and no odor, restoring heat to the home the same day. Carbon monoxide readings at the supply registers tested at zero, giving the family confidence in the repair. The homeowner reported the system reached setpoint faster than it had in two winters and scheduled a maintenance agreement to prevent a repeat failure.
Full Ductwork Replacement for Zilker Ranch Home
Zilker, TX
A Zilker ranch home with crushed, leaking flex duct received a complete duct system replacement that balanced airflow across every room.
Outcome: Duct leakage dropped to under 5 percent on the post-installation pressure test, and the west-side rooms now cool within two degrees of the thermostat. The homeowner reported the system runs noticeably quieter and that the house reaches setpoint roughly twice as fast on hot afternoons. Utility usage for the following summer dropped compared with the prior year despite a hotter season.
Cold-Climate Heat Pump Installation in Cedar Park
Cedar Park, TX
A Cedar Park homeowner replaced an aging gas furnace and AC combination with a high-efficiency cold-climate heat pump system.
Outcome: The home maintained its setpoint through a January freeze without leaning on the backup heat, and the homeowner reported the system was quieter than the old condenser. Measured heating performance met the manufacturer's rating at design temperature, and the household eliminated its gas connection entirely. The homeowner also noted a reduction in winter utility costs compared with the prior heating season.
Smart Thermostat and Zoning Controls Upgrade in Tarrytown
Tarrytown, TX
A Tarrytown two-story home received a smart thermostat and zone control upgrade to end a long-running upstairs-versus-downstairs comfort battle.
Outcome: The temperature spread between floors narrowed to roughly one degree, and the homeowner stopped manually closing vents entirely. Runtime reports in the app showed the system cycling less frequently while maintaining tighter setpoints, and the homeowner could monitor and adjust the home remotely during a two-week trip. The homeowner described the upgrade as the first time the upstairs had been genuinely comfortable in summer.
Commercial HVAC Retrofit for South Congress Retail Space
South Congress, TX
A South Congress retail space received a full HVAC retrofit that replaced mismatched equipment and resolved chronic humidity and comfort complaints.
Outcome: Indoor humidity now holds between 45 and 50 percent even on the most humid days, eliminating the display case condensation issue. The store remained open throughout the project, and staff reported noticeably more consistent temperatures across the sales floor. The property manager noted that the phased approach avoided any membrane warranty concerns and that the new controls provide clear runtime and alarm reporting.
Emergency HVAC Repair on a 100-Degree Austin Afternoon
Downtown Austin, TX
A downtown Austin condo lost cooling during a triple-digit heat wave, and an emergency repair restored operation the same evening.
Outcome: Cooling was restored the same evening, and the condo returned to its setpoint within about 90 minutes. Temperature split measured within the manufacturer's specification, and the condensate drain flowed freely with no overflow recurrence. The homeowner enrolled in a maintenance plan that includes a pre-summer drain and capacitor inspection to reduce the risk of another mid-summer failure.
Rooftop Unit Replacement for Round Rock Office Building
Round Rock, TX
A Round Rock office building replaced two end-of-life rooftop units with high-efficiency equipment and updated curb adapters.
Outcome: Both units were operational by Sunday evening, and the office opened Monday with no disruption to tenants. Refrigerant top-offs are no longer needed, and the economizer operation is expected to reduce cooling energy during mild months. The property manager confirmed the curb and flashing work passed roof warranty inspection, and tenants reported more even temperatures across the east wing.
