Why Choose High-Efficiency: These furnaces feature advanced technology with AFUE (Annual Fuel Utilization Efficiency) ratings of 90% or higher, minimizing energy waste and lowering utility bills.
Features: Look for ENERGY STAR-certified models to maximize savings.
Considerations: High-efficiency units typically cost more upfront but pay off in long-term energy savings.

Proper Sizing for Your Home

Selecting the right furnace size is critical for efficient performance and consistent heating. A system that’s too small will struggle to heat your home, while an oversized furnace can cycle on and off too frequently, reducing its lifespan.

How Professionals Size Furnaces

A professional contractor will perform a load calculation, considering factors like:

Home Size: Square footage directly affects heating requirements.
Insulation: Well-insulated homes require less heating capacity.
Windows and Doors: The number and quality of windows and doors impact heat retention.
Climate: Concord’s relatively mild winters mean most homes won’t need the same heating capacity as colder regions.

Key Features to Consider

Modern furnaces include advanced features that improve comfort, efficiency, and convenience:

Variable-Speed Blowers

Provide consistent airflow for even heating throughout your home.
Reduce energy consumption by adjusting speed based on demand.

Smart Thermostats

Zoning Systems

Divide your home into zones with independent temperature control, reducing energy waste by heating only occupied areas.

Energy Efficiency Ratings

Furnace efficiency is measured by its AFUE rating, which represents the percentage of energy converted to heat. For example, a furnace with a 90% AFUE converts 90% of its energy into usable heat, while the remaining 10% is lost.

AFUE Rating Tiers

Standard Efficiency: 80%–85% AFUE (older or budget models).
High Efficiency: 90%–97% AFUE (modern systems, often ENERGY STAR-certified).

High-efficiency furnaces cost more upfront but save significantly on energy bills over time.

Installation Matters

Proper installation is just as important as selecting the right furnace. A poorly installed system can lead to reduced efficiency, frequent breakdowns, and safety hazards.

Why Hire a Professional Contractor?

Safety: Professionals ensure secure gas or electrical connections and proper venting to prevent hazards like gas leaks or carbon monoxide buildup.
Efficiency: Proper installation ensures your furnace operates at peak performance, reducing energy waste.
Compliance: Licensed contractors adhere to local building codes, ensuring your installation meets legal requirements.
Warranty Protection: Most manufacturers require professional installation to validate warranties.

Is It Worth Replacing a 20-Year-Old Furnace?

As your furnace ages, you may begin to notice declining performance, increasing repair costs, and higher energy bills. If your furnace is 20 years old or more, you’re likely wondering whether it’s time to replace it. The answer often depends on factors like its efficiency, repair history, safety, and the benefits of upgrading to a modern heating system.

This guide will explore the key reasons why replacing a 20-year-old furnace is often a worthwhile investment and what to consider when making the decision.

Signs It’s Time to Replace Your Furnace

While furnaces can last up to 20–25 years with proper maintenance, they often show signs of wear and inefficiency as they age. Here are the top indicators that replacing your 20-year-old furnace is the best choice:

Declining Energy Efficiency

Older furnaces have lower AFUE (Annual Fuel Utilization Efficiency) ratings compared to modern systems. A furnace built 20 years ago may have an AFUE rating of 70% or lower, meaning 30% or more of the fuel it consumes is wasted.

Impact on Utility Bills: Reduced efficiency leads to higher energy costs, especially during cold months when the furnace works harder to maintain a consistent temperature.
Modern Advantage: New furnaces with AFUE ratings of 90%–97% convert more energy into heat, reducing waste and lowering your utility bills.

Frequent Repairs

As furnaces age, their components begin to wear out, leading to more frequent repairs. Common issues with old furnaces include:

Faulty heat exchangers.
Malfunctioning thermostats.
Failing blowers or motors.

If you’re spending hundreds of dollars annually on repairs, replacing the unit is often more cost-effective. A good rule of thumb is to consider replacement if the cost of repairs exceeds 50% of the price of a new furnace.

Inconsistent Heating

Older furnaces often struggle to heat your home evenly, resulting in hot and cold spots. This inconsistency can make certain areas of your home uncomfortable and force the furnace to work harder, further reducing its efficiency and lifespan.

Strange Noises

Unusual sounds such as banging, rattling, or squealing are common in older furnaces and indicate worn-out or failing components. While some issues can be repaired, recurring noises often signal that the furnace is nearing the end of its life.

Safety Concerns

A 20-year-old furnace poses safety risks, including:

Carbon Monoxide Leaks: Cracks in the heat exchanger can release dangerous levels of carbon monoxide, a colorless, odorless gas that can be fatal.
Electrical Hazards: Aging electrical components increase the risk of short circuits or fire.

Upgrading to a modern furnace with advanced safety features ensures peace of mind for you and your family.

Benefits of Replacing a 20-Year-Old Furnace

While the upfront cost of a new furnace may seem significant, the long-term benefits often outweigh the initial investment. Here’s why replacing your old furnace is worth it:
