Armstrong’s Features
Energy Efficiency up to SEER 20
The SEER rating of an AC indicates the energy efficiency of the cooling unit. The more efficient the system, the higher the SEER rating. It will result in lower utility bills.
While Armstrong’s heat pump lineup doesn’t boast the highest SEER ratings available in the industry, their variable speed 4SHP20LX with a SEER rating of 20 puts it well into Energy Star-certified territory.
Integrated Compressor Protection
Armstrong ACs are built with high and low-pressure switches in all its models. The high-pressure switch will protect the compressor if the refrigerant ever exceeds safe levels. The low-pressure switch will prevent moisture from being drawn into the system in a low-pressure situation.
MHT Technology
This is Armstrong Air’s proprietary heat transfer system. A specially designed fan will pull air for cooling through all the coils of the heat pump evenly. The rifled tubing of the coil enhances refrigerant flow, while the design of the coil fins increase surface contact between metal and air. Together, they provide maximum heat transfer and efficiency.
Comfort Sync A3 Thermostat
Exclusively available with Armstrong’s Pro Series heat pumps, the Comfort Sync A3 Thermostat will continuously monitor the system components to optimize climate control and efficiency. It’s WiFi connected for control from anywhere with a smart device.
Armstrong AC Pros
- Proven track record with a solid parent company.
- 10-year warranties for all units, plus Lifetime compressor warranty on the top model.
- Compressor protection with built-in high and low-pressure switches.
- 4 of the 6 models are Energy Star certified.
Armstrong AC Cons
- Limited selection of models.
- Only average SEER ratings.

Armstrong Heat Pump Submitted Prices and Details
| Brand & Model & SizePriceHome LocationHome Size |
|---|
| 2 ton 8.5 HSPF 4SHP16LT$1,899 (2010)Texas2200 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. |
| ?4SHP13LE$2,960LA1600 sqft |
| 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. |
| 5 ton 4HP13L$2,900Centerville, OH1600 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 |
| 4SHP18LT$5,900Pittsburgh, PA3650 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! |
