Furnace Replacement
Furnace replacement is the process of removing an old, inefficient, or broken heating unit and installing a modern, high-performance system. Upgrading to a new furnace helps improve energy efficiency, lower heating bills, and ensures consistent warmth throughout your home. Contact your local Bryant dealer to start to the process today.
Quick Answer: Repair or Replace?
Unsure if you need a full replacement? Industry experts suggest the $5,000 Rule: Multiply the age of your furnace by the estimated repair cost. If the total exceeds $5,000, replacement is generally the smarter investment.
Also, consider replacement if:
- Age: Your furnace is over 15–20 years old.
- Cost: The repair bill is over $1,000 (especially for units 13+ years old).
- Performance: You notice rising energy bills, uneven heating, or strange noises.
Andrew Mackey, owner of Superior Service in Lake St. Louis, Missouri, stresses the importance of considering both the age and efficiency of a furnace when deciding whether to get a furnace repair or furnace replacement. He often shares a simple rule of thumb with customers:
“If the furnace is 15 years old or more and the repair is over $1,000, we usually advise that it makes the most sense to replace the unit,” Mackey said.
Key Factors When Choosing a New Furnace
Replacing your furnace is a significant investment in your home's long-term comfort. To make the best choice, you need to balance initial costs with long-term savings and performance features.
1. Proper Sizing and Capacity
One size does not fit all. A furnace that is too big will short-cycle (turn on and off rapidly), wasting energy and wearing out parts. A unit that is too small won't keep up on the coldest days. A professional HVAC assessment ensures your new unit is sized perfectly for your home's square footage and insulation levels.
2. Fuel Source Options
Your local energy costs will largely dictate the best fuel source for you:
- Natural gas furnace: The most popular choice for efficiency and affordability where gas lines are available.
- Electric Furnace: Often easier to install and often cheaper upfront, but can have higher monthly operating costs depending on electricity rates. gas vs electric furnaces.
- Oil Furnaces: Oil furnaces can be a good option for homes in rural areas where natural gas lines aren’t available, but they require regular maintenance and have fluctuating fuel prices.
- Propane Furnaces: Propane furnaces are another option where natural gas is unavailable. They are typically more expensive than natural gas but offer better efficiency than electric or oil units.
3. Efficiency Rating (AFUE)
The Annual Fuel Utilization Efficiency (AFUE) rating measures how much fuel your furnace converts into heat.
- Standard Efficiency: Typically around 80% AFUE.
- High Efficiency: 90% to 98.3% AFUE.
- Why it matters: A higher AFUE rating means less wasted fuel and lower monthly energy bills. While high efficiency furnaces cost more upfront, they often pay for themselves over time.
4. Comfort Technology (Furnace Stages_
Not all furnaces heat the same way. The "stage" of your furnace determines how precisely it controls temperature:
- Single-Stage: Operates at 100% capacity whenever it's on. It's affordable but can cause temperature swings.
- Two-Stage Furnace: Has a "low" and "high" setting. It runs on low most of the time for efficiency, kicking into high only when needed. Learn more about 2-stage furnaces.
- Modulating Furnace: The gold standard for comfort. It adjusts heat output in tiny increments (like a dimmer switch) to maintain a precise temperature with minimal energy use.

5. Noise Levels
If you value a quiet home, look for models with variable-speed blowers. Unlike standard fans that blast air at full volume, variable-speed units ramp up gently, running quietly in the background to keep air circulating without the roar.
Why Upgrade? The Benefits of a Modern System
Beyond just keeping the heat on, a modern furnace replacement offers transformative benefits for your living environment.
- Lower Energy Bills: Modern standards are strict. Replacing an old 60-70% AFUE unit with a 95%+ model can drastically cut your heating costs.
- Consistent Comfort: Features like modulating burners eliminate the "blast of hot air followed by a cold draft" cycle common in older units.
- Smart Home Ready: Many new Bryant furnaces integrate seamlessly with smart thermostats, allowing you to control your climate from anywhere and optimize schedules for savings.
- Peace of Mind: New units come with robust warranties—often 5 to 10 years on furnace parts and even lifetime coverage on critical components like heat exchangers.

Furnace Replacement FAQs
Installing a new furnace typically costs between $3,800-$12,000, depending on the type, efficiency rating, brand, and installation complexity.
Yes, replacing a 20-year-old furnace is usually worth it, as newer models offer better efficiency, reliability, and may lower your energy bills and maintenance costs.
Yes. Most furnaces last around 15–20 years, so a 25-year-old system is well beyond its prime and likely less efficient than newer models.
Multiply the furnace’s age by the estimated repair cost. If the result is more than $5,000, replacement is typically the more cost-effective choice.
Homeowners insurance doesn’t usually cover furnace replacement unless it was damaged by a covered peril, like a fire or storm. Wear and tear or age-related failures are excluded.
The best deals often come in the spring or early fall, when HVAC demand is lower and contractors may offer seasonal discounts.
