When your heating system fails during winter, quick action can help protect your home and family while awaiting professional service. Understanding basic emergency procedures helps maintain safety and minimize damage during heating emergencies.

First, check the basics: ensure your thermostat is properly set and has working batteries, verify that circuit breakers haven't tripped, and check that all gas valves (if applicable) are in the proper position. If you have a gas furnace, confirm that your pilot light is lit if your system uses one.

Take immediate steps to preserve heat and protect your home. Close all windows and doors, block drafts with towels or weatherstripping, and close off unused rooms. Open curtains on south-facing windows during sunny days to capture solar heat, but close all window coverings at night for insulation.

Know when to call for emergency service. Signs requiring immediate professional attention include unusual noises, burning smells, or complete system failure during extreme cold. RM Mechanical provides 24/7 emergency service to address critical heating failures promptly.

While waiting for service, use safe temporary heating methods if necessary. Never use outdoor heating equipment indoors, and ensure any space heaters are UL-listed and placed away from flammable materials. Keep family members in a central heated area if possible.
