But before we dive into Trane furnace models, there are two other sections. The first gives a little background on Trane as a company as well as features and incentives that only a Trane furnace can offer.

The second section breaks down relevant HVAC jargon. This can help you understand some of the other features of the furnaces that we’ll talk about a little further into the article.

An Introduction to Trane

For over 130 years, Trane has been at the forefront of HVAC innovation.

In 1885, Norwegian immigrant James Trane opened a plumbing shop in La Crosse, Wisconsin. Soon after, Trane invented a low-pressure heating system.

In 1910, Trane and his son Reuben began manufacturing early HVAC systems. Reuben later invented the convector radiator.

Since then, Trane has continued to manufacture innovative, high-quality HVAC products, making strides in heating, cooling and energy management. And Trane’s on a winning streak – Trane has been named America’s most trusted HVAC brand every year since 2015.

But how does that affect you today? Let’s bring things back to 2021 and talk about the features, incentives and issues that modern Trane furnaces offer.

Features of Trane Furnaces

As an HVAC industry leader, Trane offers advanced, patented technology that you won’t find with any other brand.

Some of these technologies include:

• The Comfort-R airflow system offers enhanced airflow.
• The Vortica II blower design further increases blower motor efficiency.
• ComfortLink II communicating technology gives you advanced control over your HVAC system, offering the highest level of customization on the market.

Issues with Trane Furnaces

Of course, even the best products can have their issues.

Trane’s S-series furnaces, which include the Trane S9V2 and the Trane S8X2, have smaller furnace cabinets. While this can make S-series furnaces a great option for those with space constraints, it also means that Trane’s S-series can suffer from increased static pressure.

Static pressure is essentially your HVAC system’s blood pressure. Like your body, your HVAC system does require some pressure in order to work properly. But too much static pressure can result in poor airflow.

Fortunately, a good HVAC contractor should be able to adjust your system to relieve some of this pressure.

If space isn’t an issue, your HVAC partner should build a platform for the Trane S-series furnaces we install. This increases airflow between your furnace and your filtration system, decreasing static pressure.

But if space is an issue, your HVAC partner should install a wraparound component that also allows for more airflow without costing you space.

Once one of these measures is in place, your HVAC partner should double-check the system’s static pressure levels. After that, regularly changing your filter is the best way to keep your system’s static pressure levels down.

Become an Expert: HVAC Terminology

To get the most out of this article, you need to know a little about the following:

• Furnace efficiency ratings
• Communicating and non-communicating systems
• Gas valve staging
• Blower motor speed

This article is primarily organized based on two factors: furnace efficiency ratings and sophistication (communicating technology).

This section provides a little information on each of these. But if you’d like to dive a little deeper, check out our complete guide to home furnaces.

Furnace Efficiency Ratings

Manufacturers score furnace efficiency with Annual Fuel Utilization Efficiency (AFUE) ratings.

AFUE ratings describe the percentage of fuel that a furnace uses to provide heating. For example, a furnace that has an AFUE rating of 80% uses up to 80% of the fuel it consumes to heat your home. The system then exhausts the other approximately 20% as waste gases.

Furnaces are divided into two efficiency categories:

1. Standard efficiency furnaces, which are typically around 80% efficient
2. High-efficiency, which are 90% efficient and higher

Communicating vs. Non-Communicating HVAC Systems

In non-communicating HVAC systems, the thermostat sends signals to the heating system and the cooling system to regulate the temperature inside your home.

In communicating HVAC systems, your heating system and your cooling system can send signals back to your thermostat as well. This allows your thermostat to monitor and adjust your system’s performance.

Communicating systems can also use remote sensors placed throughout your home to precisely maintain your set temperature.

This technology also allows a communicating system to “learn” your heating and cooling needs and adjust to keep you comfy.

Furnace Gas Valve Staging

A furnace gas valve provides your furnace with fuel. But gas valves also help control your furnace’s heating output. Gas valves can have between one to 100 output settings, also known as stages.

A furnace can have one of three types of gas valves:

1. Single-stage
2. Two-stage
3. Modulating

Single-stage furnaces have one heating output: 100% capacity. This means that a single-stage furnace is either on or off.

Two-stage furnaces have two heating outputs: 100% and a lower setting that’s typically between 60-70% capacity.

Modulating furnaces can have five to 100 output settings that can range from 40% capacity to 100% capacity. This allows modulating furnaces to maintain your home’s temperature to a fraction of a degree.

Blower Motor Speed

Your furnace’s blower motor is responsible for circulating air throughout your home all year long.

Trane furnaces offer two options:

1. Fixed-speed blower motor
2. Variable-speed blower motor

Trane’s newer fixed-speed furnaces have ECM motors. Your HVAC partner can program your furnace’s ECM motor to run at a particular speed, which can also boost your air conditioner or heat pump’s performance.

However, a fixed-speed blower motor can only operate at one speed.

On the other hand, variable-speed blower motors offer more control over your HVAC system. Not only can variable-speed blower motors run at a range of speeds, but you can also control the speed of your system’s blower motor from your thermostat.

Variable-speed blower motors also help your system better circulate conditioned air throughout your home. This is why we recommend a furnace with a variable-speed blower motor if you have issues with airflow, hot and cold spots or uneven temperatures.

High-Efficiency Trane Gas Furnaces

Trane offers high-efficiency furnaces with up to 96% efficiency that can help reduce your gas bill or decrease your environmental impact.

If you think a high-efficiency furnace could be a good option for you, there’s one important factor to consider.

High-efficiency gas furnaces require a particular type of flue system to comply with manufacturer specifications and local building codes. This flue system, known as direct venting, requires an HVAC contractor to run two PVC pipes from your furnace to the outside world.

This type of venting supports your furnace’s efficiency. One PVC pipe draws fresh air from outside while the other exhausts waste gases and other byproducts into the atmosphere.

However, this will require your HVAC contractor to cut holes in the exterior of your home to accommodate the two pipes, which are between 2-3 inches in diameter.

If your HVAC partner is unable to properly install a direct venting system, you’ll likely need a standard-efficiency furnace instead. (We’ll talk about Trane’s standard-efficiency furnaces a little later in this article.)

Trane’s high-efficiency, non-communicating furnaces include:

• Trane S9V2
• Trane S9X2
• Trane S9X1
• Trane S9B1
