Furnaces can fail for many reasons, leading to a sudden comfort and air quality emergency. A sudden failure of your furnace requires you to act quickly to protect your family and home. It helps to know the steps to take if your furnace suddenly stops working. Our team at Honest Air Conditioning in Mesa, AZ is here to help with information and professional support.
When Your Furnace Fails on a Cold Night
When you hear your furnace turn off suddenly or notice the room getting colder, check other areas of your home to see if this is an isolated issue. There may be an issue with your breaker panel, resulting in certain appliances, lights, or devices not working.
If the electricity is on but the furnace isn’t responding, check the thermostat display. A blank or frozen screen could mean a tripped breaker or dead batteries. Change your batteries and inspect your breaker to see if this is the source of the problem.
If the furnace has power but does not produce heat, take a moment to check your HVAC filter. A filter clogged with debris can disrupt airflow and cause the furnace to shut down. Avoid issues by replacing your filter every 30 to 90 days.
It’s also wise to look at your outdoor vent or exhaust pipe. Snow, leaves, and debris can block the opening, preventing proper ventilation. Improper venting can also trigger a safety shutdown. Clearing the blockage can sometimes make the heating system work again.
If none of these issues fix the problem, switch the focus to staying warm until professional help arrives. Remaining in one room and shutting the doors to any unused areas will help you retain heat. Wear extra layers of clothing and use warm blankets to maintain body heat.
Common Furnace Issues
If your blower motor fails, it’s not possible for heat to circulate throughout your home. Your entire unit may remain off if it senses there is a problem. Electrical issues, worn bearings, or overheating may be to blame.
The ignition process must operate properly for your furnace to run. We can inspect gas lines and components to diagnose a startup issue. New units tend to use electric ignitors. Dirt buildup or faulty sensors may be preventing the startup process.
If You Suspect a Gas Leak
A gas leak requires a prompt response. Natural gas is highly flammable, and even turning on a light switch can cause an explosion. The first sign of a natural gas leak is usually a rotten egg or sulfur smell. If you ever notice this smell, get everyone out of the house immediately.
Call 911 once everyone is safe outside and well away from the residence. You can also call your utility emergency line. Gas professionals and firefighters go through extensive training to locate and contain gas leaks. Never try to figure the problem out on your own.
After immediate danger passes, you need to schedule a professional inspection of your furnace. We will check the gas valve, burner, and ignition system for leaks. Our professionals will also inspect levels of ventilation.
Responding to a Carbon Monoxide Emergency
Unlike natural gas, carbon monoxide has no smell. It’s also invisible to the naked eye. This is why you need a working carbon monoxide detector on every floor of your home and near bedrooms.
Carbon monoxide is a product of the combustion process. That means it can come from your furnace, fireplace, or gas appliances. A cracked heat exchanger or a blocked flue can allow carbon monoxide to seep into your home. It can reach dangerous levels quickly. You may notice people in your home experiencing headaches, flu-like symptoms, dizziness, nausea, or fatigue. Do not overlook these warning signs. It’s best to get everyone out immediately and call for help.
Turn off your furnace, and open windows to let in fresh air, only if it’s safe to do so. Call 911 from outside. Emergency responders can check the carbon monoxide levels in your home. Do not go back into the home until you are told it’s safe to do so.
Once it’s safe, schedule an appointment to have your furnace checked. Our technicians at Honest Air Conditioning will verify that the heat exchanger has no cracks or damage. We will check for proper ventilation to ensure harmful gases do not accumulate in your home.
Prevention is always best. Routine furnace inspections can reveal potential carbon monoxide problems before they ever reach a dangerous level. Annual inspections give you peace of mind knowing your family is safe.
When to Call and When to Evacuate
Homeowners sometimes avoid calling for help because they’re afraid of overreacting. It is always better to be safe than sorry. When there is fuel, fire, or carbon monoxide involved, waiting can be deadly. Always evacuate first and then call for help.
In less urgent situations, such as a mechanical breakdown, it’s best to contact an HVAC company that can offer fast, reliable service. Our technicians handle standard breakdowns, along with more hazardous issues. We arrive ready to handle problems with your fuel supply, ignition, electrical controls, and airflow. Our professionals restore your heat quickly and safely so you can maintain a comfortable home again.
Preventing Future Furnace Emergencies
While some emergencies are unavoidable, you can prevent many issues by using consistent maintenance and staying aware of what’s going on in your home. Homeowners often underestimate the importance of being prepared.
Professional maintenance is one of the best things you can do to prevent furnace emergencies. Over time, dust and debris can clog filters, vents, and combustion chambers, leading to overheating, short-cycling, and ignition issues.
Staying Calm and Acting Quickly
When your furnace fails, it’s natural to panic. However, staying calm can help you think clearly, allowing you to make better decisions. Have warm clothing and emergency supplies available. Create a family plan so that every person in your household knows what to do and where to go in the event of a furnace emergency. Communication is critical when time is limited.
If your home loses heat and you cannot restore it quickly, resist the urge to use unsafe heating sources. Focus instead on conserving warmth, contacting help, and relocating if indoor temperatures become uncomfortably chilly.
