What Counts as an AC Emergency?

• No cooling during a heat wave or vulnerable occupants at home.
• Burning, electrical, or chemical odors; smoke; tripped breakers.
• System short‑cycling, hard starts, or loud banging/grinding.
• Ice on lines or coils; airflow drops; warm air from vents.
• Water leaks near the air handler or ceiling stains.
• Thermostat failure or unresponsive controls.

If you notice any of these, power the system off and call us. We’ll guide you on safe next steps and dispatch a residential emergency technician.

Our Emergency Repair Process

• Arrival and safety check: We stabilize the situation and protect your home.
• Engineer‑level diagnostics: Electrical, refrigerant, airflow, controls, and mechanical checks.

Healthy Air at Home

Your comfort isn’t just about temperature—it’s about health. During emergency repairs we also evaluate filtration, airflow balance, drain sanitation, and coil cleanliness. Ask about upgraded filtration, sealed ducts, and smart controls to stabilize humidity and reduce airborne irritants.
Our mission is simple: healthy air at home for a healthy life.

Tips Until We Arrive

• Turn the thermostat to OFF if you smell burning or see ice on the lines.
• Set the fan to ON for 30–60 minutes to help thaw a frozen coil.
• Replace a dirty filter if you have a spare.
• Open interior doors for better airflow; close blinds on sun‑exposed windows.
• Place towels near active condensate leaks and a pan under attic air handlers if accessible.
