🔥❄️ Furnace Turns On… Then Shuts Off Too Soon? (Short Cycling) ❄️🔥

If your furnace starts up but shuts off before the home reaches the set temperature, that’s called short cycling. It may still heat a little, but it’s usually a warning that the system is dealing with airflow restrictions, overheating, or a safety control shutting the heat down. Left alone, short cycling can cause higher bills, more wear on parts, and eventually no heat.

At Uptown Heating & Air Conditioning, we find the real cause and get your furnace running steady, safe, and reliable again.

⚠️ Common Signs
✔️ Furnace runs for a few minutes, then shuts off
✔️ Temperature never reaches the thermostat setting
✔️ System restarts again and again
✔️ Heat feels inconsistent from room to room
✔️ Burning/hot smell or weak airflow (sometimes)

⚠️ Most Common Causes
✔️ Dirty/clogged air filter restricting airflow
✔️ Overheating → limit switch tripping for safety
✔️ Dirty flame sensor (burners won’t stay on)
✔️ Blower motor / capacitor issues reducing airflow
✔️ Blocked vents/returns or duct restrictions
✔️ Pressure switch / venting problems
✔️ Thermostat wiring or placement issues

🚫 Avoid This: Constantly resetting the furnace. It can cause lockouts and more wear.
