- A review of portable air conditioners with heat pump heating and recommendations on features and models. Find out how these devices work, what important features you should consider, how they performed in our testing and how to set them up in your home. These devices cost around $500-700 and are very effective as supplemental heat - a great solution for renters.

Wow! wonderful information, been looking for this. Thank you so much!
Thanks, it was very helpful.
Great video. Gave me a lot of information.
Excellent video, however I haven't had a great experience with one-hose models (specifically the Black & Decker). One-hose models act like a fan placed in your window blowing out, creating negative pressure in the room and causing ambient air to get sucked in to replace the outgoing air. It sorta defeats the purpose and significantly lowers efficiency. As an example, in a bedroom with the door closed, I ran it on heat mode for 3 hours and only managed to lift the temp from 52 to 56-well below the performance of my 1500w space heater.
I just ordered one of the new Cooper & Hunter AC+heat models, CH-STLS-14AC, that has a 2 in 1 hose, variable inverter, and 8.9 CEER rating (vs. 5.9 for their other dual hose model). It was $607 on Amazon before tax. Fingers crossed it works well!
I also considered dual-hose models from the brand NewAir, which were quite affordable ($400 shipped after using a 25% off discount code I found) and looked nice. Ultimately decided to spring for the inverter and 2 in 1 hose (for the aesthetics).
Following up to say the C&H model has been amazing-it heats my living room, dining room, bathroom, and kitchen! Quieter and cycles on & off way less than the Black & Decker. Wifi works great for scheduling it to turn on before we wake up or get home.
Combined with regular space heaters in the two bedrooms, I'll be able to avoid turning on our gas furnace entirely this year. 🎉
@@LoganInTheWilderness Thanks for the update!
just curious if the dual hose on the Midea/toshiba can be turned to use in a vertial sliding window?
It would be nice if you would include cost of operating these things. How much power they consume in $$
Just moved from the Tenderloin (Hot) to the Westside (cold lots of fog) Any Ideas? I am now just heating my bed room with forced air but The apartment is almost 500 SF
Is the CEER rating same as SEER? I couldn't find that anywhere for portable units.
Wow, this was really great info and helpful! I'm looking for a solution to heat an enclosed and insulated side porch with a regular door from the main house. No way to run existing HVAC to it. I wanted to get one of these, but can't if it can't run below freezing. I'm wondering if my best solution is to just leave the door open and let the heating/cooling from the main house take car of the space.
Johndoe - currently, these portable units will not operate below about 38 degrees, but there will be units that are capable of operating at lower temperatures available in the next year or so. They will be considerably more expensive - more like $3K. The existing units would work for much of the year and would provide AC, but would mean that you would have to rely on electric resistance heaters like space heaters or wall cadets for the times when it gets below 38 degrees. The other option would be a mini split heat pump - more like $5-6K.
Thanks for the end of the video! Question, which unit has the lowest operational temperature? I think that would be most important when using them as heat sense, it doesn’t matter if we can’t use them in the cold climates
TekShinji - all the units we reviewed have a similar operating temperature which is a few degrees above freezing. This is because none of them have defrost cycles like outdoor heat pump units. We find they are great for supplemental heating in fall and spring but may not work in some areas if temperatures get below freezing.
They all are pretty similar in this respect from my research - they will not operate below 45 degrees F - this is why you should think of them as supplemental heat unless you live in a mild climate.
In another review, the Black & Decker model shown recycled condensate and blew it out the window vent.
It's rather unfortunate that so much of the time was spent focused on condensate. The simple solution is to boost the machine 6 to 8 inches above the ground, run the hose into a 40 dollar HVAC condensate pump (about the size of a lunch box) which has a float switch and can then pump the water through a hose out a window or down a drain. Holistically I can understand it; it is totally unacceptable to be having to empty condensate into a cookie tray every few hours. What I'm most concerned about is which of these units have a true defrost function, or which ones have software that just shuts them down when the temperature goes below about 40 Fahrenheit. I live in a colder climate, and even with the reduced efficiency at lower temperatures, it is still far more efficient than electric resistance heating.
When will the cold 🥶 weather update be ready for heating below 40 degrees please ?
How about heating in a cold climate? I understand these either lose efficiency when outside temperatures drop under 40 degrees, or stop heating at all
Don - you are correct - these portable units will only provide heating down to external temperatures of about 40 degrees, so they are great for supplemental heating for rooms that are not well served by central systems or to reduce use of gas heating or expensive baseboard heating but can not replace heating systems altogether unless you are in a mild climate. They also provide Air Conditioning, which is great for homes that have no AC or for rooms that are not well served by central systems.
Black and Decker AMBIENT WORKING TEMPERATURE HEAT: 50°F (10°C) - 77°F (25°C).
The one i am looking at Amazon is Cooper & Hewitt AC+heat models, CH-STLS-14AC, it has 61F for ambient for heat mode.
So does this mean that the heat function will not work if outside temperature is
Bud - yes that is correct. The models I researched in the video work to 45 degrees F but not below that.
@@ElectrifyNowUSA thanks for the info.
I recently got this C&H model (see my other comment). It's been fantastic, and has worked into the high 30s for us. (It might even work lower, but thankfully SF temps stay above freezing!)
@@LoganInTheWilderness I am still confused though about this C&H model spec. since it indicates the ambient (outside?) for heat is 61F or higher, it can be 36F here in Bay area. May be 61F is a typo?
@@budmartin3344 it must be, as it's worked into the high 30s for me in San Francisco.
"map14hs1tbl" I could not find anywhere in the manual that it has a built-in condensate pump nor in the parts list available for purchase.
ooo, only for heat pump mode from what I understood. I only need heat pump mode one month out of the year in arizona...
that model definitely has a condensate pump but it is set up to work in heat mode. my understanding is that far less condensate is produced in ac mode and most of it is removed by the hot air which is blown out of the house in ac mode. this means you should not need a condensate pump in ac mode.
My concern is how long these units will last. If I pay $700 for a portable inverter HP (I would only buy one with inverter tech) it's going to have to last several years to pay for itself & in my experience with current dehumidifiers they don't last long & generally are not repairable...especially if they lose their refrigerant. Just my 2 cents.
yes i also think they will break too early and make the whole process useless
pls discuss the refrigerants used in the reviewed heat pumps. is it a natural refrigerant (e.g. CO2) or some synthetic hydrochlorofluorocarbon? the latter have high global warming potential, may be toxic or flammable.
Yes.
These units do not use CO2 - they use conventional refrigerants like the ones found in all heat pumps, refrigerators and air conditioners. Thanks!
@@ElectrifyNowUSA Yes.
Yes.
Who gives a crap
one day these window units will be great .. currently they are not .
Efficiency probably because bad. HSPSF MUST BE HIGHER than 8.2 for energy star
