How to spot HVAC sizing issues in 78643 and when load calculations are needed.

Popular neighborhoods we cover in 78643: Kingsland, The Legends, Bridgepoint.

Homeowners in ZIP 78643 usually call us for recurring comfort issues, inconsistent airflow, and unexpected HVAC shutdowns. A fast diagnosis helps prevent larger repair bills and keeps your system reliable during extreme weather.

Our technicians focus on practical next steps: verify thermostat operation, inspect airflow and filter condition, check electrical components, and confirm safe temperature performance at the equipment and vents.

Quick Homeowner Checklist

  1. Confirm thermostat settings. Confirm the thermostat is set to COOL (or HEAT), the setpoint is at least 2°F below room temperature, and fresh batteries are installed.
  2. Replace the return-air filter. Check and replace a clogged return-air filter. A dirty filter is the #1 cause of weak airflow and frozen coils.
  3. Check every vent. Make sure all supply and return vents are open and unobstructed by furniture, rugs, or closed dampers.
  4. Inspect around the equipment. Look for water, ice, or unusual noises around the indoor air handler and outdoor condenser. Shut the system off and call a pro if you see any of these.
