What should I do if my HVAC system needs emergency repair now?

If your HVAC system needs emergency repair now, call Lanz Plumbing, Heating & Cooling, Inc. for 24/7 dispatch and we’ll send a technician right away. Most emergency no-heat or no-cool calls trace to issues like a failed igniter, bad flame sensor, blower motor problems, or thermostat malfunctions, which we diagnose and fix promptly. Our technicians follow a clear repair process—assess, test, adjust, then clean up—so you know exactly what’s happening. We offer flat-rate pricing, no after-hours fees, and a 100% satisfaction guarantee after the core diagnosis begins. Our team handles urgent calls across the Champaign–Urbana area every day.

While you wait, take these quick steps:

• Set the thermostat to Off and fan to Auto if you smell burning, see smoke, or find water around equipment.
• Check the breaker and the furnace/air-handler switch; restore power only if tripped once.
• Replace a severely clogged filter to improve airflow.
• For furnaces, note any error light blinks; for AC, don’t chip ice off coils.

Do not keep trying to run the system until a technician inspects it.
