HVAC Emergency Preparedness: What Every Homeowner Should Know

An HVAC emergency never happens at a convenient time. It's always the coldest night of winter or the hottest day of summer. Knowing how to respond — and how to prevent emergencies in the first place — can save you money, stress, and potential safety hazards.

Know your system's emergency shutoff. Every homeowner should know where the electrical disconnect for their HVAC system is located. For furnaces, know where the gas shutoff valve is. If you smell gas or see sparking, shut the system off immediately and call your utility company before calling an HVAC company.

What to do if your AC fails in summer. Close blinds to block solar heat, open interior doors to circulate air, use fans to create airflow, and stay hydrated. If temperatures inside exceed 85°F, consider leaving the home — especially with elderly family members, young children, or pets.

What to do if your heat fails in winter. Close off unused rooms and gather in one space. Use space heaters safely (keep 3 feet from anything flammable, never use extension cords). Open faucets to a drip to prevent pipe freezing. Never use your oven or stove for heat — this is a carbon monoxide hazard.

Carbon monoxide: the silent danger. Gas furnaces can develop cracked heat exchangers that leak carbon monoxide. Install CO detectors on every level of your home and near bedrooms. If your CO detector alarms, evacuate immediately and call 911 — not your HVAC company.

Signs of an impending emergency. Strange noises (banging, screeching, clicking), unusual odors (burning, rotten eggs, musty), short cycling (turning on and off rapidly), and ice formation on your outdoor unit are all warning signs. Don't ignore them — a $200 repair today prevents a $5,000 emergency tomorrow.
