The Westinghouse WPac14000h Portable AC is a 4-in-1 unit that cools, heats with a heat pump, dehumidifies and runs as a fan. It adds Wi-Fi app control and one of the most complete window vent kits we have seen among portable air conditioners. The listing shows a 3.9 out of 5 average across more than 185 ratings.
One point needs clearing up first. The title lists 14,000 BTU, but the feature list gives 12,000 BTU ASHRAE and 8,150 BTU DOE. We treat the 8,150 BTU DOE figure as the most reliable guide to real cooling.
Our Verdict
The WPac14000h is a good fit for a bedroom, office or apartment where you want one unit for both summer cooling and mild winter heating. The heat pump is more efficient than a resistance heater, the Wi-Fi app adds convenience, and the window kit includes a rain guard, screen and foam seal that cheaper kits skip.
The compromises are size and capacity. At 34.1 inches tall it is a large unit, and 8,150 BTU of DOE cooling will not cover the 700 square feet the listing suggests. Size it for a medium room and it is a versatile year-round choice.

Cooling Capacity and Room Size
The listing gives conflicting capacity numbers. The title says 14,000 BTU, while the feature list states 12,000 BTU ASHRAE and 8,150 BTU DOE. The DOE number accounts for heat a single-hose portable adds back into the room, so it is the best figure for comparing portables.
Westinghouse claims coverage of up to 700 square feet, a space it compares to a typical family room. With 8,150 BTU of DOE cooling, a medium bedroom, office or small apartment is a more realistic fit. In a large, sunny family room, the unit will run hard and may not reach your set temperature on hot afternoons.
The compressor is a non-inverter type, and the fan offers two speeds.
Heating
Heat mode is the main reason to pick this model over a cooling-only portable. Westinghouse describes the unit as a room air conditioner with a heat pump, which moves heat into the room rather than generating it with a resistance element. That makes it an efficient way to take the chill off a room in spring and fall.
The listing does not give a heating BTU rating. Like most portable heat pumps, it is best treated as supplemental heat for mild weather, not a replacement for a central heating system in cold climates.
Installation and Fit
Westinghouse says installation takes about 5 minutes. The kit is unusually complete: an exhaust duct and connector, a quick-adjust window panel with an extension panel, a watertight adhesive foam seal, a leak-proof rain guard and screen, and an exhaust cover. It is designed for double-hung or sliding windows.
The quick-adjust knob makes it easy to size the panel to your window. The rain guard and screen help keep water and insects out, which is a nice upgrade over basic kits.
The unit measures 15.6 by 18.1 inches at the base and stands 34.1 inches tall, so plan for a fairly large footprint near the window.
Noise, Energy Use and Efficiency
Westinghouse says the unit runs as low as 52 dBA, about as quiet as a normal conversation, and quieter than a standard window air conditioner. Sleep mode runs more quietly and saves energy at night.
Rated power is 1250 watts on 115 volts. The listing’s other efficiency numbers are inconsistent, so we would not rely on them. Use the timer and app to run the unit only when you need it.
Controls and Smart Features
You can control the unit three ways: the top panel with simple touch controls, the included remote from up to 20 feet away, or the smartphone app over Wi-Fi. The app lets you power the unit on and change settings when you are away from home.
A programmable timer turns the unit on or off automatically, and an adjustable humidistat lets you set a target humidity in dehumidifier mode.
Dehumidifying and Maintenance
As a dehumidifier, Westinghouse says the unit removes up to 90 pints of moisture per day in spaces up to 4000 square feet. That is a strong figure and useful in damp basements or humid summers. Check the manual for the drainage setup when you run dehumidifier mode for long periods.
The cleanable air filter should be rinsed every couple of weeks during heavy use. Drain and dry the unit before storing it.
Year-Round Use
The appeal of the WPac14000h is that it can stay in place through most of the year. In summer it cools and dehumidifies. In spring and fall, heat mode takes the chill off a bedroom or home office without running a whole-house system. On damp days in between, dehumidifier mode with the humidistat helps the room feel fresher.
That flexibility is worth more than raw capacity for many buyers, especially in apartments where a central system is shared or hard to control.
Pros and Cons
| Pros | Cons |
|---|---|
| Heat pump for efficient supplemental heat | Listing capacity numbers conflict |
| Wi-Fi app, remote and touch controls | 700 sq ft claim is optimistic |
| Complete window kit with rain guard and screen | Large 34.1 inch tall body |
| Up to 90 pints per day dehumidifying | Only two fan speeds |
| As low as 52 dBA | No heating BTU rating listed |
Who Should Buy It
| Who Should Buy It? | Who Should Look Elsewhere? |
|---|---|
| Bedrooms and apartments that need cooling and heat | Large family rooms in hot climates |
| Humid homes that need strong dehumidifying | Buyers who need a compact unit |
| Renters who want app control | Cold climates that need primary heat |
| Buyers who want a complete window kit | Buyers who want clear, consistent specs |
Final Verdict
The Westinghouse WPac14000h Portable AC is a versatile 4-in-1 unit with a heat pump, Wi-Fi app control, strong dehumidifying and a complete window kit. It suits a medium room that needs both cooling and mild heating. Size it by the 8,150 BTU DOE figure rather than the 700 square foot claim.
