Pros and Cons of American Standard Gas Furnaces

Many people choose American Standard for the high level of quality the furnaces have. The brand has an excellent service record. The furnaces are reliable and long-lasting.

Secondly, the efficiency levels in the top models are a good choice for those who want to contain energy costs as well as be more environmentally friendly in the way their homes operate.

If there’s a drawback to the product lineup, it is that it is expensive. Along with the quality and the performance come higher costs. However, the furnaces are priced competitively with other top brands, though more costly than brands such as Goodman, Aire-Flo, Payne, York and Coleman.

AAA Rated Furnaces

What are the best gas furnaces currently available?  These 5 are the cream of the crop. If you’re looking for a very efficient, high-quality gas furnace, this list is a great place to start your search.

1. Trane Fully Modulating XC95m Gas Furnace

Trane is one of the highest-rated furnaces for quality and dependability. This furnace adds indoor comfort to the list of reasons to consider Trane’s best gas furnace. The modulating gas valve runs at lower capacity most of the time so that the cycles are longer and gentler. The air is also filtered more frequently. The variable-speed blower matches the performance of the gas valve to balance temperatures so that you won’t notice fluctuations during or between cycles. This is a pricey gas furnace, with costs ranging from $1,900-$3,000.

2. American Standard Platinum ZV Gas Furnace

This top model from AS has a modulating gas valve to go with Energy Star 95% efficiency. The result is a very comfortable home along with lower energy use and bills. American Standard’s service record is a top-5 in the industry too, making this a great long-term furnace choice. Gas furnace prices for this model are $2,100-$2,800.

3. Goodman GMVM96 Modulating Gas Furnace

Goodman specializes in making quality products for less and backing them with very good warranties. This is the brand’s top of the line. It offers precise climate control with a modulating burner that delivers just the right amount of heating required to balance temperatures throughout the home. It runs at capacity as low as 35% producing very quiet, very gentle heat. Here’s proof of the good value these furnaces represent – the cost is $1,600-$2,100 depending on the size you get.

4. Lennox Signature SLP98V Variable-Capacity

This is a remarkable gas furnace, with 98.2% energy efficiency. It’s very popular in the coldest climates and it is a favorite with enthusiasts of eco-friendly heating and cooling. The variable-speed blower enhances your indoor comfort in all seasons. You’ll pay more for this furnace, as you might expect. Depending on capacity, the gas furnace prices are $2,600-$3,500.

5. Luxaire LX TM9M Gas Furnace

Luxaire doesn’t have the reputation or name recognition that the heavyweights like Trane and Lennox do. But that doesn’t stop the company from turning out highly-rated products. This furnace is efficient at 97%. The modulating gas valve also makes it very comfortable. You’ll enjoy better climate control with the variable-speed blower whether it is heating or working with a central air conditioner to cool your home and remove humidity. Prices for this model are $2,400-$3,000.

When you replace an older gas furnace with one of these, you’ll first notice much better climate control. They will even out temperatures throughout your home, helping to eliminate hot and cold spots (which could be a ductwork issue too).

The second thing you’ll notices is heating bills that are much lower. If the furnace you’re replacing is 15-25 years old, it’s probably 65%-85% efficient, so do the math and see how much you’ll save!

See our gas furnace ratings for more details on many of these models. They’re a great way to compare models head to head.

What are the Differences in American Standard Gas Furnaces?

Those interested in the American Standard lineup may ask, ‘what are the differences in American Standard gas furnaces?’  This gas furnaces guide provides you with an overview that makes it easy to compare American Standard models to one another as well as to those from other manufacturers.  American Standard makes 3 series of gas furnaces, Platinum, Gold and Silver.  Here is a look at each one’s strengths and basic features.

American Standard Platinum Gas Furnaces

There are 2 models in this top of the line series.  Both feature variable-speed fans which optimize indoor comfort by balancing temperatures and improving air filtration and humidity control whether heating or cooling.  They are equipped with Comfort-R constant low-fan mode that removes more humidity when cooling.  The Platinum ZV is the best of the bunch and is 95% efficient.  It is American Standard’s entry into the modulating furnace category that is filling up with models from all the top manufacturers.  The burner heats from 40% to 100% capacity in order to provide a climate without noticeable temperature fluctuations.  The Platinum SV furnace is an 80% efficient companion to the ZV for those in milder/warmer climates where higher efficiency isn’t needed.  Both of these models include the AccuLink communicating technology that coordinates the entire HVAC system for maximum efficiency. American Standard Platinum Series furnaces are backed by a lifetime heat exchanger warranty and a 10-year parts warranty.

American Standard Gold Gas Furnaces

The Gold ZM furnace is excellent, getting high scores in gas furnace ratings. It is 96.7% efficient and equipped with Comfort-R technology.  It provides 2-stage heating and a variable-speed blower.  The only thing that differentiates it from the Platinum ZV is the lack of communicating technology.  However, it costs less, making it a good value. The 2-stage heating and 2-speed fan on the Gold XM doesn’t provide as precise climate control, but better than a single-stage furnace.  It is 90% efficient and is a popular furnace in all climates.  The Gold SI is a single-speed model with 92% efficiency, providing basic heating for those who want higher efficiency but don’t want to pay extra for staged heating and a variable-speed blower.  Finally, the Gold SM furnace, at 80% efficient, provides comfortable 2-stage heating and outstanding affordability. All Gold Series models from American Standard, except the Gold SM, are backed by a lifetime heat exchanger warranty and a 10-year parts warranty.  The Gold SM furnace has a 20-year heat exchanger and a 10-year parts warranty.

American Standard Silver Gas Furnaces

These furnaces are designed for affordability and are equipped with single-speed blowers, though some have 2-stage burners.  The Silver ZI is 96.7% efficient with a 2-stage burner.  It is backed by a lifetime heat exchanger warranty and a 10-year parts warranty. The Silver SI offers a 90% efficient model and an 80% efficient model, all with single-stage/single-speed operation. The heat exchanger has a lifetime warranty and the parts are covered for 5 years.  The Silver XI is 80% efficient and has a 20-year heat exchanger warranty and a 10-year parts warranty.


American Standard models tend to do very well in gas furnace ratings within their class.  They are, on average, also priced moderately higher than some comparable furnaces.  For long-term durability they are worth it.  If you are looking for a shorter-term furnace, more affordable models might make better sense.  Here is an overview of the furnaces:

American Standard Platinum Series: Platinum ZV (95%) and SV (80%).

American Standard Gold Series: Gold ZM (96.7%), Gold SI (92%), Gold XM (90%), Gold SM (80%).

American Standard Silver Series: Silver ZI (96.7%), Silver SI (90% and 80%), Silver XI (80%) and Silver SI+ (80%).

Performance Features Rating: (4.5/5)

American_Standard_gas-furnace_rating_pic The most unique feature of the American Standard Platinum ZV gas furnace, and the one that contributes most to indoor comfort and efficiency, is the modulating gas valve.  Furnaces with 2-stage gas valves offer 2 levels, usually about 65% and 100% firing.  This furnace gauges the heat needed and modulates burner operation anywhere between 40% and 100%.  This provides very comfortable heating without cool startups or abrupt shut-downs.  It contributes to balanced heating throughout your home.

The American Standard Freedom 95 Comfort-R furnace is also equipped with a variable-speed blower that works in tandem with the modulating gas valve for gentle comfort.  When the system is equipped with a 2-stage central air conditioner, the Comfort-R technology ensures lower humidity levels by running the system for longer periods of time by using the low setting.  Models are offered with upflow/horizontal and downflow/horizontal design so that this furnace may be installed virtually anywhere.
