An unexpected breakdown can quickly turn your cool, comfortable home into a stifling and stressful environment—not to mention an expensive emergency repair.

Top AC Warning Signs Before a Heat Wave

Weak or warm airflow: could be a clogged filter, dirty coils, duct leaks, or failing compressor.
Unusual noises: buzzing, banging, or screeching often indicate loose parts or electrical issues.

Spiking energy bills: suggest decreasing system efficiency—service can help restore performance.
Water leaks or moisture: may signal blocked drains or refrigerant leaks—repair promptly to avoid damage.

Overdue annual tune‑up: skipping yearly maintenance allows small issues to escalate.

When should you repair your HVAC system — and when is it time to replace it?

Major component failures can also signal it’s time to upgrade.
