Homeowner Guides
Simple tips to protect your system
Practical advice for keeping your heating and cooling running smoothly — no jargon, no fluff.
Change your air filter regularly
Check it monthly and replace every 1–3 months. A clogged filter restricts airflow and makes your system work harder — especially during Austin summers.
Schedule a tune-up →Keep the outdoor unit clear
Trim back plants and clear leaves or debris within about two feet of your condenser. Good airflow helps your AC cool efficiently and last longer.
Know when to call a pro
Warm air, water leaks, burning smells, or loud banging aren’t DIY fixes. Turn the system off and schedule service before a small issue becomes a costly repair.
Learn about repair →Schedule before peak season
Book AC maintenance in spring and heating service in fall. You’ll beat the rush, catch problems early, and stay comfortable when Texas weather turns extreme.
Book maintenance →Set your thermostat wisely
78°F is a solid starting point when you’re home in summer. Raise it a few degrees when you’re away — each degree can trim cooling costs without sacrificing much comfort.
Don’t block your vents
Closed or covered registers strain your system and create hot or cold spots. Make sure furniture, rugs, and doors aren’t blocking airflow in any room.
