Heating and cooling that survives a Texas summer

In North Texas the cooling system runs near capacity for four months. Most mid-summer failures trace back to airflow: a loaded filter, a blocked return, or a dirty coil.

Checklist

  • Change filters monthly during peak cooling
  • Keep two feet clear around the outdoor unit
  • Rinse the condenser fins each spring with a garden hose, never a pressure washer
  • Service the cooling system in February, before the rush
  • Service the heating system in October

Safety first

  • Refrigerant handling is licensed work
  • Gas furnace repairs are not DIY
  • A cracked heat exchanger is a carbon monoxide risk — replace the unit or the exchanger
