Overview of the 4SHP16LT

The Armstrong Air 4SHP16LT is a discontinued two-stage, 16 SEER heat pump. The two-stage Copeland Ultra Tech scroll compressor operated on low speed most of the time for optimal efficiency and comfort, and the unit was dual fuel compatible, allowing it to be combined with a gas furnace for increased efficiency. The compressor was protected by high- and low-pressure switches and a bi-directional filter drier, and a compressor sound blanket helped keep operating noise levels as low as 73 decibels. The unit's Comfort Alert 2 diagnostics system monitored the operation of system components, and removable panels allowed easy cleaning and service. A galvanized steel cabinet with baked polyester paint finish and a raised base pan with drain ports provided protection from rust and corrosion.

Review:
"Outstanding and very quiet unit"
So I read a bunch of reviews on Armstrong Air after it was recommended by a contractor I know. I cannot stand when someone comes on and gives a product a 1 star review, and then proceeds to explain how crappy the contractor was in their review. So...once I took out the 1-2 star reviews that clearly had an issue with their contractor and quality of installation, rather than equipment, the satisfied score went up quite a bit, and I took a chance on it. We live in Katy, Texas, which is just west of Houston, and had a Rheem unit for the last 7 years in a 7-year-old home which has given us nothing but problems. The contractor installed the Armstrong 2-stage 16-SEER communicating heat pump with a variable speed air handler and Armstrong's Comfort Sync thermostat a little over 3 months ago. The contractor did a quality install and the unit operation reflects it. When he first started up the unit I waited to see when it would come on. Little did I know, the unit was already running but was so quiet that I couldn't tell whether it was on until I stood under the air supply grille. The thermostat is very easy to set up and use, it's fully WiFi and gives me access to the system from anywhere via free app. Another cool thing it does is troubleshoot itself, and when my filter was a little too dirty because I forgot to change it with 3 large dogs in the house, I got a notification on my cell and on my thermostat that my filter was dirty and recommended changing it. Did I mention this thing is freaking quiet? I wish I had the money to go with their Inverter 20 SEER product that the contractor tried to upsell me to, but alas, I couldn't justify spending $12,000 on a system that I'm going to leave to someone else in 3-4 years when we sell, as we are planning to do. Overall, I was extremely pleased with how this unit runs and how it is built. 3 months in and my highest electric bill on a 2,400 square foot house which is kept at 76 during the day and 72 at night has been $156.00 and that was this last billing cycle, 2/3 of which was July.

Review:
"Poor installers"
I have been in the plumbing and heating (boilers) business since 1973 and over 20 years as a contractor. I was also an AO Smith service tech for years and found almost all problems were installer caused. I purchased my equipment through my wholesaler and found what I thought was a knowledgeable installer. Ends up I knew more about the proper way to install the unit and components. Every manufacturer has different specifics on installing their products and if a contractor has a one size fits all installation procedure beware. In my case, Armstrong was new to our area and there were no installers familiar with their products. So, find a brand product you like, then search for a contractor that has used that product for years. They will be the most experienced in the proper installation procedures for that manufacturer and would have dealt with the many issues over the years from the mistakes they have made. Although the basics of heat pump systems are the same there are some minor tweeks in installation that could cause future problems. These are very complex systems with advanced electronics to produce the most efficient means for heating/cooling and your joe blow installer just doesn't have the knowledge and training to set everything up properly for peak performance. Yes, I have had some issues with my Armstrong (owned by Lennox with almost identical technology and equipment) but I also pay attention to my system and address problems as they occur. Most recently my unit was defrosting too often. I did some testing and found the plug in connection at the defrost board had over the years developed some corrosion. The sensors tested out properly and the board was fine, just a little cleaning and a little grease and it's working fine again. You may have had to pay 200-300 for a tech to find that for you. Everything today is so complex with many of the things we own. HVAC equipment is no exception. Be prepared for breakdowns in even the best and most costly and for the associated repair bill. If not, buy a bunch of electric oil heaters and place them around your home. You'll just throw it away and go get another and you won't have to hire someone to do it. My two stage heat pump and variable speed propane furnace are quiet and more efficient than my old system. I was able to sell both heat pump and furnace on Craigslist since they still worked and also got a nice tax credit to boot.

"MODEL???????"
Please tell the model or seer rating of your heat pumps. I have a model 4shp16lt124p - 16 seer New installation 18 months ago. Unit has only functioned properly for 3 months. It is being replaced by the supplier. The contractor wants to replace it with a 4shp14le118p - 14 seer " less problems". Does any one have the 4shp18lt124p - 18 seer unit? I see it has a 10 year warrenty on parts.

Review:
"Armstrong"
Model: 4shp16lt Series Split System Heat Pump Unit has failed 6 times in 12 months. Make that 7 times in 13 months. It has failed again, and again. I am running on auxilliary heat. Control board failures, mechanical failures, switching valve failures. The control on the exchanger in the duct has failed. Unit compressor operation has become very loud. If I lived in the city or an urban area, I would not be allowed to run it at night. We often switch to auxilliary heat at night anyway so we can sleep. The system had been a constant aggravation.
