If you live in Springfield, Missouri, where winters can get pretty chilly with temperatures dropping below freezing, a high-efficiency furnace might save you big on heating bills. At SS&B Heating & Cooling, we've helped many local homeowners upgrade their old furnaces to high-efficiency models. These units use less fuel while keeping your home cozy. In this blog, we'll explain what a high-efficiency furnace is, how it works, and if it's worth the extra cost for folks in our area. Whether you're in Nixa, Ozark, or right here in Springfield, understanding these options can help you make a smart choice for your home. We carry top brands like Trane and RunTru to fit different budgets and needs.

Why Consider a New Furnace in Springfield?

Winters in southwest Missouri aren't as brutal as up north, but we still see plenty of cold snaps. From November through March, your furnace works hard to fight off those frosty nights. If your current furnace is over 15 years old, it might be time for a replacement. Old units waste energy, leading to higher natural gas bills from City Utilities or other providers in the area.

At SS&B Heating & Cooling, we specialize in furnace installation and replacement in Springfield, MO, and nearby spots like Republic and Willard. We've seen how new technology has changed the game. High-efficiency furnaces use advanced features to save energy and provide better comfort. If you're searching for "furnace replacement Springfield MO" or "best high-efficiency furnace near me," you're in the right place. We offer Trane for premium performance and RunTru for reliable, affordable options. Let's dive into the details.

What Exactly Is a High-Efficiency Furnace?

A high-efficiency furnace is one that turns most of the fuel it uses into heat for your home. The key measure here is AFUE, which stands for Annual Fuel Utilization Efficiency. This rating shows what percentage of the fuel gets used for heating instead of being lost as waste.

For a furnace to be called high-efficiency, it needs an AFUE of 90% or higher. That means at least 90% of the natural gas goes toward warming your house, with only 10% or less escaping as exhaust. Compare that to older models, which might have an AFUE of just 80%—losing 20 cents of every dollar you spend on gas.

In Springfield, where we rely on natural gas from local suppliers, this efficiency matters. High-efficiency units are often condensing furnaces, which capture extra heat from exhaust gases. Brands like Trane and RunTru, which we carry at SS&B, offer models with AFUE ratings up to 97%. RunTru provides great value for those wanting high efficiency without the premium price tag. If you're dealing with rising energy costs in Missouri, these furnaces can help keep your bills down.

How Does a High-Efficiency Furnace Work?

High-efficiency furnaces work smarter than traditional ones. Let's break it down step by step.

First, all gas furnaces burn natural gas to create heat. The hot gases from this burning process go through a heat exchanger—a metal part that transfers the heat to the air in your home. Your blower fan then pushes that warm air through your ducts.

What makes high-efficiency models different is the second heat exchanger. In a standard furnace, the exhaust gases go straight out the vent after passing through one heat exchanger. But in a condensing furnace, those gases move to a secondary heat exchanger. Here, they cool down more, turning water vapor into liquid. This process releases even more heat, which gets used to warm your home.

The leftover water drains away safely, and the cooler exhaust can vent through PVC pipes instead of a metal chimney. This setup not only boosts efficiency but also uses flexible PVC venting, though new pipes may be required if replacing an older model. At SS&B Heating & Cooling, our technicians can assess your setup and recommend the best Trane or RunTru high-efficiency furnace for your needs.

Types of Furnaces: Single-Stage, Two-Stage, Modulating, and Variable-Speed

Not all furnaces run the same way. Understanding the differences can help you pick the right one for your Springfield home.

Single-Stage Furnace: This is the basic type. It's either off or running at full blast (100% capacity). It heats quickly but can cause temperature swings, making some rooms too hot or cold.
Two-Stage Furnace: These have two settings—high and low. On milder days, it runs at about 60-70% capacity for steady heat. This leads to more even temperatures and lower energy use. In Missouri's variable winter weather, a two-stage model shines.
Modulating Furnace: The most advanced, with a modulating gas valve. It adjusts output from around 40% to 100% in small steps, matching your home's exact heating needs. Pair it with a smart thermostat, and you'll get top comfort and efficiency.
Variable-Speed Furnace: This refers to the blower motor. It runs at different speeds for better air circulation. It's great when combined with a heat pump or air conditioner for year-round control. In humid summers here in Springfield, it helps with dehumidification too.

Trane and RunTru offer these options, and at SS&B, we install them with local expertise. For example, a Trane XV95 two-stage furnace with 96% AFUE is popular for premium setups, while RunTru's A951X offers similar efficiency at a lower cost—ideal for budget-conscious homeowners in Ozark or Nixa.

Comparing Efficiency: 97% AFUE vs. 80% AFUE

Let's talk numbers. A standard 80% AFUE furnace gives you 80 cents of heat for every dollar spent on gas. The rest? It goes out the chimney. A 97% AFUE model delivers 97 cents of heat, saving you 17 cents per dollar.

Over a winter in Springfield, that adds up. If your monthly gas bill is $200 from October to March (that's six months), you're spending about $1,200 a season. With a high-efficiency upgrade, you could save $200 or more yearly, depending on your home size and insulation.

We crunched some local numbers: In Missouri, average natural gas prices are around $1.20 per therm. A 2,000-square-foot home might use 800 therms in winter. At 80% efficiency, that's higher costs. Switch to 97%, and you save on fuel while reducing wear on the system.

Real SS&B customers in Ozark have reported 20-30% lower bills after upgrading to Trane or RunTru models. Plus, rebates from Spire Energy or federal tax credits can offset the upfront cost.

Is It Worth the Cost? Weighing the Pros and Cons

High-efficiency furnaces do cost more upfront — typically $6,500 to $9,000 installed, compared to $4,000 to $6,500 for standard models. That’s because a true high-efficiency install isn’t a “swap-and-go.” It includes new PVC venting, condensate drain setup, gas piping adjustments, thermostat integration, and full system commissioning to ensure peak performance and safety.

However, their improved efficiency and available rebates can offset much of that difference over time. Over 15–20 years, these systems can save $5,000 or more in fuel costs, and their quieter operation and better airflow add comfort that’s noticeable every day.

RunTru models often start at the lower end of the range, making high-efficiency heating more accessible for Springfield homeowners who want the benefits of modern performance without the premium price tag.

Here’s what to consider:

Climate: With 30–40 heating degree days each winter month, Springfield homes benefit from greater efficiency.
Home Size: Larger homes and families that heat more space see the biggest savings.
Financing: SS&B offers flexible HVAC financing options through trusted partners, spreading payments over time with low interest.
Rebates: Missouri programs and manufacturer promotions can help offset costs. Locally, City Utilities of Springfield provides $400 rebates for qualifying high-efficiency natural gas furnaces (95%+ AFUE).

If you heat often — or simply want lower bills and steadier comfort — a high-efficiency furnace is well worth the investment. For homes with lighter heating needs, a mid-efficiency model can still deliver reliable performance at a lower upfront cost.
