6 Signs Your Furnace Isn’t Working

Joshua East • March 17, 2023

Furnaces are complicated appliances that can be difficult to figure out. Sometimes, it’s hard to tell if an issue can be resolved on your own or if it requires expert assistance.

If you suspect that your furnace may not be working, don't ignore the signs. Knowing when your furnace needs repair can help you save time and money in the long run.

To help you out, we put together a list of signs your furnace isn’t working. Read on to learn about red flags to watch out for so you’ll know how to handle potential problems.

1. It’s difficult to start the unit.

A common issue is having trouble starting and maintaining the device. Get an experienced HVAC contractor to look at your furnace if you notice that it takes a number of tries to start or you need to restart it frequently during the day. Having clean filters, functioning AC coils, and fixing auxiliary heat exchangers often solve many of these problems.

2. You hear unusual noises.

Many furnaces make a steady whirring sound that lets you know that it’s in good condition. But when you start to hear odd noises, such as pounding, rattling, irregular hums, moans, or rattles, they’re signs of a problem.

Contact a professional HVAC contractor if the noises persist so they can determine the source of the issue.

3. You notice water spills.

If you see a pool of water near your furnace, it might be a sign of a water leak. But don’t worry because if it’s fixed right away, it won't cause major problems.

A break in the condensation line or a clogged condensation drain might be the issue. Additionally, a clogged internal drainage system or an issue with your humidifier may be the source of your water leak.

A furnace HVAC repair contractor can locate the problem quickly and make sure that the water leak doesn't cause more challenging issues like mold growth.

4. Your house isn't properly heated.

One of the signs your furnace isn’t working is when air isn’t blowing through it.

A broken blower motor, which prevents the system from forcing air through the ventilation system, is one main reason for this. Even though it can be a fairly straightforward problem to address, it can also be an indication of other HVAC repair issues that are more complicated and costly to fix.

The same goes when heat isn’t being distributed throughout a space evenly. When you use a functioning heating system with a single zone setting, the temperature in every area in your house should be roughly the same.

5. Your energy costs are higher than usual.

Your furnace is certainly working inefficiently and needs to be repaired if you see a significant monthly increase in your energy bill. While you should anticipate seasonal fluctuations, if you notice an abrupt or steady increase in your bill, it may indicate that your furnace isn't operating as it should. In this case, you should probably call an HVAC maintenance technician to have a look.

6. Your furnace begins needing more frequent repairs.

Unfortunately, nothing lasts forever, including your furnace. Furnaces typically last 15 to 20 years. They also go through regular wear and tear, increasing their susceptibility to damage over time.

Therefore, one of the signs your furnace isn’t working is if you keep contacting HVAC repair services. It could make more sense to purchase a new system than to spend money on frequent repairs.

If you aren’t sure how old your HVAC system is, your service technician may be able to locate the model and serial number so you can discover the date when it was manufactured.

Emergency Heating Tips for Unexpected Cold Snaps

January 16, 2025

Emergency Heating Tips for Unexpected Cold Snaps: Staying Warm and Safe When Your Heating System Fails When the mercury plunges unexpectedly, the last thing you want is a heating system that quits on you. Such emergencies not only make your home uncomfortable but can also pose serious risks to your health and safety. At Second 2 None Service Co, we understand the urgency of these situations. Here's a comprehensive guide to help you navigate the cold safely if you find yourself without heat. Understand the Risks The first step in dealing with a heating emergency is understanding the risks associated with cold indoor temperatures. Hypothermia can occur even inside if temperatures drop significantly. Older adults, children, and those with chronic medical conditions are particularly vulnerable. Recognizing the signs of hypothermia, which include shivering, slurred speech, and unusual tiredness, is crucial. Immediate Steps to Take If your heating system stops working, here are some immediate steps you can take to retain heat and stay warm until help arrives: Insulate Your Home : Close all windows and doors tightly. Use towels or blankets to block drafts under doors or around window frames. This can significantly reduce heat loss. Retreat to a Smaller Room: Choose a smaller room to stay in as it will be easier to keep warm. Close the doors to any unused rooms to avoid wasting heat. Layer Up: Put on multiple layers of clothing. Wearing a hat and gloves indoors can also help retain body heat. Use Safe Alternative Heat Sources: If you have a fireplace, use it. However, ensure the chimney is clear and open to avoid smoke inhalation and carbon monoxide buildup. Never use outdoor heating devices like barbecues indoors. Cover Floors with Rugs: If you have bare floors, covering them with rugs can help insulate the room and keep your feet warm. Long-term Preparations While the immediate measures can help, preparing for heating emergencies before they occur is crucial. Here’s how you can prepare: Regular HVAC Maintenance: Ensure your heating system is inspected and maintained by professionals like Second 2 None Service Co annually. This not only prevents many emergencies but also ensures your system runs efficiently. Invest in a Programmable Thermostat: A programmable thermostat can help maintain a steady temperature in the home, and some models can alert you to temperature drops that might indicate a heating failure. Keep Emergency Supplies Ready: Have a supply of warm blankets, non-perishable food, water, and a first aid kit readily available. Also, keep a battery-powered radio and extra batteries at hand to stay informed during a power outage. Consider a Backup Generator: For those in areas prone to frequent and prolonged cold snaps, investing in a backup generator can be a lifesaver. It can keep your heating system running during a power outage. When to Call for Professional Help Sometimes, the heating system may fail due to simple issues that can be resolved with quick fixes, like replacing a dirty filter or restarting the system. However, more complex problems require professional attention. If your furnace is making unusual noises, if there's a smell of gas, or if the system fails to restart, it’s time to call professionals. At Second 2 None Service Co, our expert technicians are equipped to handle emergencies promptly and efficiently, ensuring your system is up and running as quickly as possible. Preventative Measures Preventative measures can drastically reduce the chances of facing a heating emergency. Here are a few tips: Seal Leaks: Inspect your home for any leaks in windows, doors, or the foundation and seal them before the winter season. This not only prevents cold drafts but also improves the efficiency of your heating system. Upgrade Insulation: Improving the insulation in your attic, walls, and floors can significantly enhance your home’s ability to retain heat. Educate Your Family: Make sure every member of your household knows what to do in the event of a heating emergency. Educate them about the risks of carbon monoxide and the importance of ventilation when using fireplaces or other heat sources. No one wants to think about their heating system failing in the middle of a cold snap, but being prepared can make a significant difference. Remember, the team at Second 2 None Service Co is here to help you maintain your system and manage any emergencies that arise, ensuring you stay warm and safe, no matter the weather.
