When to schedule your Austin HVAC tune-up

September 2025 · 5 min read

Austin cooling season is roughly seven months long, and the first 95-degree day is when every reputable HVAC company in town stops answering the phone. The homeowners who never have an emergency are the ones who booked in February.

The Austin service calendar is backwards from the weather

Most homeowners call for HVAC service when the house stops cooling. By then technicians are running emergency calls at overtime rates and a full inspection is not on the table.

Schedule cooling service in February and heating service in October. You get a technician with time to actually test the system rather than swap a part and leave.

  • February: full cooling inspection, coil clean, refrigerant check, drain-line clear.
  • October: heat exchanger and burner inspection, safety check, filter reset.
  • Monthly, June through September: filter change while the system runs hardest.

What a real tune-up includes

A twenty-minute visit that only checks refrigerant is not a tune-up. Ask what is on the technician's list before booking.

  • Condenser coil washed, not just glanced at.
  • Condensate line cleared and the safety float switch tested.
  • Capacitor and contactor readings recorded, so drift is visible next year.
  • Static pressure and temperature split measured across the coil.
  • Attic ductwork checked for disconnected runs and crushed flex.

Signs you should not wait for the next scheduled visit

Some symptoms mean call today. Running a struggling compressor through an Austin August is how a repair becomes a replacement.

  • The system runs continuously and still drifts up in the afternoon.
  • Water stains on a ceiling below an attic air handler.
  • A burning or musty smell when the system starts.
  • Breaker trips, or the outdoor unit hums without the fan spinning.

Questions we get

How often should HVAC be serviced in Austin?
Twice a year. Cooling season here runs from roughly April into October, so one spring visit for the air conditioning and one fall visit for heat is the minimum for a system you expect to last fifteen years.
Does a tune-up actually lower my electric bill?
A dirty condenser coil and a clogged filter can cost 10 to 20 percent in efficiency. That is real money across an Austin summer, though the bigger payoff is avoiding a compressor failure in July.
What filter should I use?
A MERV 8 to 11 pleated filter suits most Austin homes. Higher ratings restrict airflow on older systems, which strains the blower and can freeze the coil.
