Warning Signs You Need a New Furnace

It’s that time of year again when the weather starts to cool down, and you may wonder if it’s time to start thinking about getting a new furnace. Here are some warning signs that it might be time for a new furnace.

AC Maintenance

Your Furnace is More than 15 Years Old

Furnaces typically last between 15 and 20 years, so if yours is on the older side, it may be time to start shopping for a new one. Replacing your furnace can mean better energy efficiency and lower monthly bills. Consider all the available options when shopping for a new furnace, including cost, fuel type, energy efficiency rating, and size. You may even want to talk to an HVAC contractor to get advice about which option is best for your home. With some research, you can find the perfect furnace to fit your needs and budget.

It’s essential to have regular maintenance performed on your existing furnace to keep it running smoothly and efficiently. Cleaning and replacing filters, checking connections, and lubricating parts are just some of the tasks that should be done every few months. 

An annual inspection by an HVAC technician is also recommended, as this will help ensure your system continues working properly for years to come. An experienced technician can also help diagnose and repair any potential problems that may arise with your furnace.

Increasing Repair Costs

If your furnace constantly needs repairs, or the cost of those repairs continues to increase, replacing it with a new model is more cost-effective. A new furnace may have more efficient features and a longer lifespan than an older one, lowering energy costs and giving you peace of mind. When selecting a new furnace, consider the size of your home, the climate where you live, the fuel type you prefer, and other factors like noise level or air quality. Your HVAC specialist can help you make an informed decision that best suits your needs.

Once you’ve selected the right furnace for your home, professional installation is essential for maximum efficiency and safety. In addition to ensuring all parts are connected correctly and safely, a professional can adjust the settings on your thermostat to work optimally with the new system. This will help ensure that your home stays comfortable and you get the most out of your new furnace.

Uneven Heating

If some rooms are too hot while others remain cold, this could indicate an issue with your furnace’s efficiency. It may be worth replacing with a newer model offering higher performance and energy savings. Alternatively, you can contact a professional for furnace repair to determine if there is an issue with your existing equipment. Additionally, consider upgrading or replacing your thermostat to improve temperature control throughout your home.

Finally, proper insulation and ventilation are essential to maximizing the efficiency of both heating and cooling systems. If you notice drafts coming from windows or doors, installing weatherstripping seals can help reduce energy loss. You can also add extra insulation around exposed pipes or ductwork for added protection against heat loss. Ensuring proper airflow through vents and registers is essential for maintaining comfortable temperatures inside your home. Taking these steps can help ensure that each room in your house remains at a comfortable temperature all year round.

Strange Noises

If you hear strange noises coming from your furnaces, such as squeaking, grinding, or banging sounds, it’s time to have it looked at by a qualified technician. You will likely need to replace the unit if the issue cannot be fixed. You should also be aware of unusual odors coming from the furnace. If you smell something that could indicate a gas leak, contact your local utility provider immediately and turn off the power to the unit. This is a severe issue, as it can lead to carbon monoxide poisoning if not addressed quickly.

Finally, pay attention to how often your furnace cycles on and off. Running continuously or turning on and off more often than usual could indicate a malfunctioning thermostat or another issue with your heating system. A professional HVAC technician can diagnose any problems and provide solutions for getting your system back in working order.

Air conditioner

Excessive Dust & Allergens

Many of today’s furnaces come with air filters designed to help reduce dust and allergens in your home. Suppose you’re not getting relief from allergies and other respiratory issues even after changing the filter regularly. In that case, it may be time to switch out the old model for a new one with better filtration capabilities. Additionally, a new furnace system can provide overall better air quality and help create improved ventilation in the home. Another reason why you may want to consider replacing your furnace is if it’s inefficient or outdated. Older models don’t meet modern energy standards, meaning they cost more to run than newer systems designed to be more efficient. Not only will upgrading to a new unit save you on monthly heating costs, but it will also keep your family comfortable during the winter months.

Finally, if you need frequent repairs or dealing with a system that runs poorly even after multiple tune-ups, it might be time for an upgrade. Investing in a new and reliable model now could mean fewer costly repairs.
