trust

If your home heater is not working, start with a few safe checks and call a qualified HVAC technician if basic steps don’t restore heat. The most common culprits are thermostat settings or power issues, followed by a clogged filter that can make a furnace overheat and shut itself down. A technician’s note: we often find a tripped high‑limit switch from poor airflow after a neglected filter. Our team handles these no‑heat calls across Lemont and nearby suburbs. For urgent situations, Windy City HVAC Repair provides same‑day and emergency help with 24/7 live customer service.
Try these quick checks before you call:
- Set the thermostat to Heat, raise the setpoint, and replace dead batteries.
- Make sure the furnace switch is on and reset any tripped breaker.
- Inspect the furnace filter; replace or clean if dirty.
- Confirm supply/return vents are open; do not relight anything if you smell gas. A burning smell, gas odor, or repeated breaker trips means shut the system off and get professional help right away.
