Cranking up the thermostat and feeling nothing but cool air pouring through the vents is sure to send a (literal) chill down your spine. Maintaining a comfortable year-round temperature is essential, but a new furnace does more than keep you cozy: it’s an investment in your home’s efficiency and safety.

Being able to spot the telltale signs of furnace failure and how to navigate common issues will help you understand when it’s time to upgrade to a new heating system.

Signs Your Furnace Needs Replacing

Aside from the obvious — you’re freezing to death even though your furnace is running — knowing your heating system is on the fritz isn’t always apparent. Pay attention to signs like:

• Age: Furnaces typically last 15-20 years. If yours is nearing or exceeding this mark, consider replacement, even if it seems functional.
• Performance: Uneven heating, frequent short cycling, unusual noises, and poor air quality can all indicate trouble.
• Cost: Rising energy bills or frequent repairs might signal an inefficient furnace nearing its end.
• Visual Cues: Cracks, rust, or pilot light issues may signify deterioration and potential safety concerns.
• Safety: Carbon monoxide leaks or burning smells demand immediate attention from a professional.

Common Furnace Issues

Many things can go wrong with a furnace, but certain issues are more common than others. Some are easy fixes you can handle yourself, while others require a visit from a service tech — and potentially a new furnace. Typical causes of furnace failure include:

• Dirty air filters: This is a major culprit for reduced airflow and inefficiency. Aim to replace your filter monthly during peak season.
• Malfunctioning thermostat: Make sure the batteries are fresh and the thermostat is programmed correctly.
• Tripped circuit breaker: If your furnace uses electricity, check your breaker box to see if a breaker has flipped.
• Pilot light problems: In older furnaces, a flickering or extinguished pilot light can prevent ignition.
• Ignition system issues: In newer furnaces, problems with the electronic ignition system can prevent startup.
• Clogged ducts: Dust and debris buildup in your ductwork can restrict airflow and reduce heating efficiency. Regular cleaning is recommended.
• Blower motor failure: If the blower motor isn't working, your furnace won't circulate warm air.
• Cracked heat exchanger: This is a serious issue that can release carbon monoxide into your home. If you suspect a crack, call a professional immediately.

Regular maintenance helps ensure your furnace performs efficiently for many years. But as any homeowner can attest, nothing lasts forever. Eventually, a new furnace is simply your best option.

Benefits of a New Furnace

Even if your furnace is still working okay, there are benefits to upgrading sooner rather than later — especially if it’s getting up there in age. Modern furnaces are significantly more efficient than older models, meaning you’ll use less fuel or electricity to heat your home, resulting in lower energy bills…not to mention a cleaner environment.

“Newer furnaces often boast efficiency ratings of 90% or higher,” explains Pete Harms of R&W Heating & Cooling. “Compare that to 60-70% for older units, and it’s pretty clear upgrading can save you significant money in the long run.”

In addition to reduced energy costs, a new furnace is safer, more reliable, and provides enhanced comfort.

New Furnace Costs

The cost of a new furnace varies depending on several factors including:

• Type of furnace: Gas furnaces are generally more expensive than electric furnaces.
• Size of your home: Larger homes, and those with multiple stories, require more powerful furnaces, which are more expensive.
• Window directions: South-facing windows let in more sunlight and warmth, while windows that face north tend to keep a home cooler.
• Furnace efficiency: More efficient furnaces cost more upfront, but can save you money on your energy bills in the long run.
• Brand and installation: Reputable brands and experienced installers might command higher prices.

Generally speaking, you can expect to pay $3,800 - $10,000 for a gas furnace and $3,000 - $7,000 for an electric furnace, including installation.
