A furnace failure during a New Britain winter can turn from inconvenient to dangerous faster than most homeowners expect. Knowing what to do in the first few minutes can make a real difference — for your safety and for the condition of your equipment. Total Comfort Solutions Heating & Air Conditioning tells you what to do when your furnace fails.
What to Do When Your Furnace Fails
Step 1: Assess the Situation
Before assuming the worst, run through the basics. Check the thermostat: is it set to heat, is the temperature set above the current room temperature, and are the batteries still good? Check your electrical panel for a tripped circuit breaker. Listen to the unit — banging, clicking, or whistling sounds provide clues about what may have failed.
Step 2: Prioritize Safety First
If you smell gas or burning, or if your carbon monoxide detector has alarmed, do not troubleshoot. Shut off the furnace using its power switch or gas valve. Do not turn lights on or off or use any appliances that could create a spark. Open windows and doors on your way out, then evacuate immediately. High CO levels are a life-safety emergency.
Step 3: Check for Simple Fixes (When It Is Safe to Do So)
If there is no safety concern, a few things are worth checking before calling for service:
- Gas furnace: check the pilot light. If it has gone out, relight it per the manufacturer’s instructions on the unit.
- Air filter: a severely clogged filter can cause the system to overheat and shut down. Replace it if it is visibly dirty.
- Exhaust vents and air intakes: check both indoor and outdoor openings for blockages from snow, debris, or nesting animals.
- Blower motor: listen for humming or grinding, which indicates a mechanical problem needing professional attention.
Step 4: Call a Professional
If basic troubleshooting does not restore heat, call a licensed HVAC technician. Mechanical failures, electrical problems, and gas line issues all require professional diagnosis and repair. When you call, describe what you observed — any noises, smells, error codes on the display, or sequence of events leading up to the failure. This helps the technician arrive prepared.
Emergency heating service is available. If you are a Total Comfort Club maintenance plan member, priority scheduling is included in your plan.
Staying Warm While You Wait
Close doors to rooms you are not using to concentrate heat in the spaces where your household is gathered. Use portable space heaters and electric blankets carefully and only as directed by their safety guidelines. If the indoor temperature drops significantly, allow faucets to drip slowly — moving water is less likely to freeze in pipes.
Check Your Warranties and Insurance
Once the immediate situation is handled, review your furnace warranty. Most warranties cover parts and sometimes labor, though they typically require documented maintenance history. Check your homeowner’s insurance policy as well — some cover furnace-related damages.
When Replacement Makes More Sense Than Repair
Some failures point toward replacement rather than another repair. Consider replacement if your furnace is more than 15 years old, has had multiple breakdowns in recent years, if the repair cost exceeds roughly half the value of the unit, or if energy bills have been climbing and comfort has been declining. A technician can help you evaluate the honest comparison.
Plan Ahead for Next Season
Most emergency furnace failures are preventable. Annual professional maintenance catches the issues that lead to mid-winter breakdowns — worn components, developing electrical problems, heat exchanger concerns — before they become failures. The best time to schedule that maintenance is fall, before the heating season begins.
