🔥❄️ Furnace Blowing Warm, Then Cold? Your System Is Overheating and Shutting Down ❄️🔥

If your furnace starts heating normally but suddenly switches to blowing cool air, it’s a major sign that the system is overheating. When temperatures climb too high, the safety limit switch shuts off the burners — leaving only the blower running.

At Uptown Heating & Air Conditioning, we diagnose overheating issues fast and protect your furnace from permanent damage.

⚠️ Common Reasons Furnaces Overheat

✔️ Dirty or clogged air filter
✔️ Blocked airflow causing high temperature rise
✔️ Dirty blower wheel reducing circulation
✔️ Weak blower motor not moving enough air
✔️ Dirty evaporator coil restricting flow
✔️ Heat exchanger overheating due to poor combustion
✔️ Faulty limit switch or wiring

An overheating furnace will shut off repeatedly — and can eventually crack the heat exchanger.
