Note: Before you dive into the specific brand review, we highly recommend you to read our elaborate Heat Pump Buying Guide in advance, there are several crucial steps you need to take before you even start to think about the brand.
Armstrong Air and Ducane are brands owned by Allied Air, a manufacturer of residential and commercial HVAC equipment. Allied Air is owned by Lennox International. However, Armstrong Air and Ducane products are not identical to Lennox-branded heat pumps. FYI, the Air Ease brand is another Allied Air brand, and it has an identical lineup to Armstrong Air.
There are six heat pumps branded as Armstrong Air. Three of those are also sold under the Ducane heat pumps name. The table below shows that Ducane heat pumps are available only in the most popular heat pump sizes.
This guide to Ducane and Armstrong Air heat pumps includes all models, their efficiency and performance features. Tables below include heat pump prices by model and size. Unit cost plus installed cost give you a clear idea of what your complete project cost will be.

Armstrong Air and Ducane Heat Pump Unique Features
Here are the top performance features offered by the heat pumps from these brands.
The Armstrong Air Pro Series 4SHP20LX is the only variable-capacity model offered by either brand. Its compressor modulates up and down between 40% and 100% of capacity, like cruise control, working only as hard as needed to keep temperatures steady. It mostly runs in the low part of the spectrum, which is also quieter and more efficient.
All heat pumps from Armstrong Air feature MHT Technology, which allows for evener heat dissipation in the outdoor coil during air conditioning cycle. A proprietary shroud pulls air evenly across the coil for faster cooling and better coil longevity.
The proprietary communicating system and thermostat control from Armstrong Air is called Comfort Sync. The system allows components to share information to produce the most evenly balanced temperatures and optimal humidity control. The Comfort Sync system is WiFi-enabled for monitoring and control using the app on an Android or iOS device. Comfort Sync can be used with zoned HVAC systems.
All models from both brands are dual-fuel capable. This means they can be installed in a split system with a gas furnace instead of an air handler. In a dual fuel (or hybrid) system, the heat pump handles heating duties until the outside temperature drops below a set point in the mid-30s. At that point, the system seamlessly switches to furnace heat, switching back to the heat pump when outside temperatures are above the adjustable set point.
All Ducane and Armstrong Air heat pumps equalize refrigerant pressure before entering defrost mode. This produces an easier shift that is quieter and better for the compressor. This is called Quiet Shift technology.
Armstrong Air and Ducane Heat Pump Cons
Let’s start with Ducane. By design, its product offering is limited to a two-stage heat pump and two single-stage models. The 16 SEER is the highest efficiency rating while many brands have SEER ratings over 20. In short, Ducane models are designed for homeowners that want good efficiency at a reasonable cost.
Armstrong Air makes a larger lineup, but there are a couple concerns. First, there is only one 2-stage heat pump, so your performance options are limited. Many brands make a 16 SEER, 17 SEER and/or an 18 SEER 2-stage heat pump for more options.
Secondly, Armstrong Air’s most efficient single-stage model is 15 SEER. Most brands make 16 SEER, single-stage models.
Armstrong Air and Ducane Model Reviews and Recommendation
Here are the essential specifications of all Ducane and Armstrong heat pumps.
|Armstrong Model||Ducane Model||7.7||HSPF||Compressor||Communicating||Other|
|Pro Series 4SHP20LX||-||20||10||Variable||Optional||Energy Star|
|Pro Series 4SHP16LS||4HP16LT||16||8.5||2-stage||Optional||Energy Star|
If you want the most efficient heat pump available and/or the one that delivers the most optimal indoor comfort, the Armstrong Air Pro Series 4SHP20LX is the choice. Just keep in mind that it must be paired with the more expensive Comfort Sync control and a compatible Armstrong Air air handler or gas furnace with Comfort Sync technology to get the best performance. Before you buy a communicating system like Comfort Sync, we recommend reading our post on Communicating vs. Non-communicating systems. The communicating technology for every manufacturer is proprietary, so they vary in reliability. If you get written estimates for Armstrong Air Pro Series heat pumps, ask the dealer if there are issues with Comfort Sync systems such as the components stop communicating.
The 16 SEER, 2-stage heat pumps from both brands ideally balance good efficiency, improved climate control vs. single-stage models and a more affordable cost than the variable-capacity model.
If you live in a cold climate and want a dual fuel system, our recommendation is the 4SHP16LS/4HP16LT 2-stage model or one of the 15 SEER, single-stage heat pumps. Pair the heat pump with an Armstrong Air furnace like the 96% efficient A962E, a 2-stage model. The results will be efficient, cost-effective heating and air conditioning.
For moderate climates like much of the West Coast, one of the 14 SEER models might be sufficient, if you’re OK with single-stage heating and cooling. These models work well in part-time locations too such as a guest apartment or vacation home.
Prices By Models
The Armstrong Air Pro Series heat pumps are made available in 2, 3, 4 and 5 ton models. The rest are available in 1.5, 2, 2.5, 3, 3.5, 4 and 5 ton models. This is common with most brands; the most expensive models are available in limited sizes since there is less demand for them.
If you’re considering BTUs for sizing the heat pump to your needs, 1 ton = 12,000 BTUs.
The heat pump installed cost includes refrigerant line set, refrigerant, condenser pad if needed, heat pump setup and the labor involved. If you’re choosing a communicating system, then it also includes the costly Comfort Sync thermostat control.
Prices by Unit Size
Proper sizing of a heat pump, along with proper installation, is just as important as the brand and model you buy. We recommend that your HVAC technician conduct a load test on your home such as the Manual J test that accounts for your climate, home’s design and materials plus additional factors that determine how much heating and air conditioning capacity you need.
See the section What Size Heat Pump Do I Need in our Buying Guide for complete details on this crucial topic.
Knowing what size heat pump you need and what they cost by size will help you select the right model for your home.
Armstrong Air makes “basic, better and best” grades while all the Ducane models are in the “better” category.
- Basic: Single-stage, 14 SEER
- Better: Single-stage, 15 SEER and 2-stage, 16 SEER
- Best: Variable-capacity, 20 SEER
This table will help you select the right grade of heat pump based on the size needed and how much you want to spend. Remember that the Armstrong Pro Series models are not available in half-ton sizes. We include home size only as a rough estimate. At each size, the price range reflects the different efficiency and performance features for various Ducane and Armstrong heat pump models.

Extracted Contractor Reviews
My minimum heat pump specs. For Chicago, I would not advise a system that lacks electronic demand and defrost that eliminates/reduces nuisance and unnecessary defrost calls not to mention the issue of wear and tear.
You have to consider things like:
Warranty on part and their options
Refrigerant line sets
back up heat strips
You will have to inspect the overall condition duct work system, return lines, size, insulation qualities and a general leak test. Personally I recommend the Armstrong, Ruud and carrier.

Armstrong Heat Pump Submitted Prices and Details
Brand & Model & Size
|$1,899 (2010)||2 ton 8.5 HSPF 4SHP16LT||Texas||2200 sqft|
|After five years of owning this system, I have had one repair, and I can say that it works efficiently and right. After the repair, I have experienced tremendous energy savings as my power bill has dropped drastically. I would recommend any person to buy Armstrong and get the best value for your money. The key to having your heat pump last long enough is to have a good installer, probably the contractor or a technician with enough experience on installation. The poor installation will make the system fail even after a few months, and then you will blame the manufacturer who is not at fault in such a scenario.|
|When I moved to this house, I felt like I was taking a chance going with an Armstrong Heat Pump because I didn’t know the brand, but I have been very pleased for the last seven years it has been in use. No trouble at all except for a few repairs here and there which are normal to all heat pumps. The price is low, and the performance is quite impressive.|
|$2,900||5 ton 4HP13L||Centerville, OH||1600 sqft|
|I have owned the 5 ton Armstrong 4HP13L for a couple of years now, and it has pretty much rocked my world. I haven’t had any problems with it at all so far. The price was high but manageable. I am yet to do any repairs or replacements of any parts, and I would buy the same brand and for sure. Compared to my previous system the Armstrong heat pump is so quiet that I’ve. I need not raise our voices when the system is working|
|$5,900||4SHP18LT||Pittsburgh, PA||3650 sqft|
|I have had the heat pump for just over two years or so, and I would purchase the same brand again. I have recommended this heat pump to a few of my colleagues. Since I am a new user, I have not had to do much for repairs or replacements. This particular unit been has been great and I hope it will not disappoint me in future. Despite the price being high, the heat pump ensures your value for your money because of its performance. It operates without the noise that you have to confirm whether it is working. If you want a unit that will last longer, you should go for this heat pump. Good job Armstrong!|
|$3,800||13 SEER 3 ton||CA||2250 sqft|
|Bought it becasue the low price compared to Trane and Carrier. But constant problems happened since the second year and spent $300 for the labor repair fee (warranty only cover the parts!) Never buy it again and you need spend twice money for the Trane!!!|
