Common HVAC Problems Dallas Homeowners Face
Dallas’s fluctuating weather puts extra stress on HVAC systems. Here are some of the most common issues Astar’s HVAC troubleshooting services in Dallas help solve:
1. AC Not Cooling or Blowing Warm Air
Possible causes include low refrigerant, dirty coils, or compressor issues. Our experts use advanced tools to test refrigerant levels, airflow, and electrical components for accurate repairs.
2. Weak or Uneven Airflow
This often points to clogged filters, duct leaks, or blower motor malfunctions. We inspect your ductwork and clean vital components to restore proper airflow.
