Cooper & Hunter15,000 BTU PTAC Packaged Terminal Air Conditioner & Heat Pump – Built-In 3.5kW Electric Heater – Includes Wireless Smart Kit, Remote, Power Cord, Sleeve & Grille – R-32 Refrigerant

So, I gave this 5 stars for one reason, it does what I wanted it to do. Lot of heat, and lots of AC. Control panel is easy, its quiet, so it got 5 stars. But there's several things I'd call "poor engineering" that I fixed after getting the unit. A couple in MY opinion could shorten the life of the unit. If you install the sleeve and outer louvers the way the instructions tell you to, the louvers are tightened from the inside and you cant remove the louver without pulling the whole heat pump out of the sleeve, and thats a 2 person job. So the louvers that are outside where hot or cold exhaust comes out, have no screen on it on the inside. So, wasps, yellow jackets, stink bugs etc can fly right in and make nests inside the unit, Not good. I think the reason they dont have a screen is what I already mentioned, you cant take the louvers off easy, so you cant clean the screen. I left my louvers a tiny bit loose by not totally tightening the 4 corner "keepers" from the inside, so I can lift the louver up and off. I am still looking for the exact screen large enough to not block exhaust, and small enough to keep bees out. Next, the sleeve has 2 drains, one left and one right. BUT, the heat pump itself sits in its own tray and that slides into the sleeve. The tray has a lip all the way around it, which fills up with water until it overflows and goes out the sleeve drain. But, when its full, you have a few components of the heat pump sitting in about an inch of water, copper tubes, aluminum fins, etc. I called the company, they said they have a temperature sensitive widget that if it gets near freezing, it opens a port to drain the water before it freezes so the components dont get frozen and damaged. What if you dont reach freezing? He didnt have an answer. I dont want things underwater or moldy water in there, so he said it was ok to drill holes in the pan. So I did, but why not drill holes at the factory and save the expense of the widget? On the inside of the unit, in the house, The directional louvers that spread the heat or cold are fixed, so no control over which direction the air flows. And lastly, when you have it going, like on heat, I set the temp for 69, it heats up our large country kitchen really fast, and goes into a sleep mode until the temp drops below 69, and then it comes back on. But there's no pilot light on the control panel, so when it goes into sleep mode, it looks as dead as if you had unplugged it. So if you have several people in the house, you really dont know if someone turned it off, or if its in sleep mode. So you have to push the on/off to find out. The inside problems you cant fix , but the outside problems are more important, and you can fix them. So there's my 2 cents worth!

Replaced an old existing unit so, installation went as smooth as one would expect. The shipping company was great. They communicated a time and were punctual. The unit arrived with no damage and works as intended. It is much quieter than i expected so thats a bonus too.

A lot of bells any whisles, cools and heats well. Relatively easy to install.

I own a few rental houses and these are perfect for just that. I recently built a home and I found that these were way more affordable than any other option out there. I installed them myself and it was super easy. Just insert and plug in. There is almost no noise they are very quiet. The size is slender so from the outside they still look nice. And they function fantastic. Better than a window unit and they heat and cool. These have a remote and rhey are Bluetooth , so they can be controlled from anywhere! That is one of the best features.

Upon the recommendation of my A/C Technician, I ordered the Cooper Hunter 12000 BTU PTAC from Amazon. Been nothing but a nightmare. Hired the Tech and his assistant to unpackage , assemble Grill and insert unit into wall. Immediately upon turning the system on, it sounded like a jackhammer drilling concrete. Amazon has been no help. Always got to contact the seller. Asked for a replacement first, then a return. Keep being told I have to return at my expense. A 60- year old dealing with this is Nerve Racking. Cost to ship at my expense exceeds $200 . Why should I have to pay for a defective/damaged product. Why should I lose money?

This unit, paired with a dedicated dehumidifier saved my large entertainment space from a chronic humidity and light mold problem. Installation was incredibly easy and being able to control it via app while away from home and as temperatures fluctuate between seasons is a godsend. I’m in love with this appliance and am so thankful for it. Very reasonably priced. If I ever need to, I will buy this unit again and highly recommend it to those who need a PTAC, Specifically. I do have a Smart Govee Dehumidifier and Smart Govee Hygrometer in the space. Between the two appliances and hygrometer unit (which comes along with an iPhone widget for easy monitoring and alerting of parameters), I can better understand the environmental conditions of my space and control it remotely without a worry. Like I said before, this unit is instrumental to creating an effective temperature and humidity ecosystem.

I have installed 3 of these in rental units so far and no problems to this point up to 15 months. The tenants say they are pleased with their power bill so far

Dimensions are correct in some places wrong in others, 42Kx16Hx21D is correct, cut hole based on first dimensions I saw and they are wrong
