(Why don't we show the price?)

Retailers have the legal right to set their own prices, but some manufacturers place restrictions on how those prices may be communicated. Because our price on this item is lower than the manufacturer's “minimum advertised price,” the manufacturer does not allow us to show you our price until you place the item in your cart, or in some cases, proceeding to the final checkout stage. Taking these steps allows Appliances Connection to show you our price consistent with our goal of always offering you the lowest possible prices on the widest selection of products. You are not required to purchase the product to see our lowest price, simply just remove it from your cart.

This portable air conditioner with heater by Whynter offers 14000 cooling BTU and 11000 heating BTU to provide comfort for the summer or winter. Capable of dehumidifying 71 pints in a 24 hour period, this portable air conditioner also features hassle-free operation by turning off when the water tank is full, cleaner and fresher air with the 3M Filter and SilverShield washable pre-filter. Available at AppliancesConnection


Easily Setup
Specifically equipped with an internal condensate pump that can be activated when using the heat function, the Whynter ARC-148MHP portable air conditioner is especially useful in high humidity conditions. The unit can be easily setup in almost any indoor location and is most commonly used in data closets / server rooms, bedrooms, classrooms and garages / workshops.

Superior Cooling and Heating Operation
The Whynter ARC-148MHP portable air conditioner provides 14,000 BTU cooling and 11,000 BTU heating output while maintaining a compact and portable profile. The dehumidifier mode allows you to extract 71 pints of excess moisture during a 24-hour period.

Hassle-Free Operation
The Whynter ARC-148MHP will never cause you a spill over. When the water tank is full, the compressor will shut down and will not start back up before the tank is emptied. Alternatively, the AutoPump function can be utilized to pump out (and up) condensate moisture through the included 16.5’ drain for continuous water removal with approximately 15’ of vertical lift.

Cleaner and Fresher Air
This unit also features a separate dehumidifying mode that enables it to be used as a room dehumidifier as needed. A 3M© Filter and SilverShield washable pre-filter are equipped standard on this air conditioner to help keep the cooled air cleaner and fresher.

Useful Features
Equipped with a remote control that can easily control the speed, temperature, timer and dehumidifier settings even from a distance, the Whynter ARC-148MHP also comes with rolling casters that will allow you to move the portable air conditioner room to room. Its programmable features, operating modes, and versatile design makes this unit a great option for keeping rooms up to 450 square feet cool and comfortable
