Great & Powerful AC Unit

3 days ago
This Keystone 8000 BTU 115V window air conditioner with 3500 BTU supplemental heat capacity is a fantastic powerful unit that anyone would be proud to own! It's specifically made for rooms 3505 SQ ft with a window with a Ht 16.5 in & a W 26.8 inches . The adjustable , pleated window mounting kit is included making installation a breeze. It's a very quiet unit with 3 cooling speeds, 3 fan speeds & 1 heat speed. An adjustable 4 way air-flow direction allows you to control the direction of the cool air with 4 way louvers. Electronic controls with LED display allows you to easily select options with the touch of a button. A temp sensing remote allows you to control temp from across the room . A programable 24 hr on/off timer cools on your schedule. In the event of a power outage an auto-restart feature saves your settings for when the power is restored. There is even an easy clean , tilt-out mesh filter with a check filter alert on the unit for easy maintenance . The 7 ft power cord uses the standard 115V electrical outlet. The installation of the unit is easy & took no time at all. The unit produces a great amount of cooling but is not meant to be used as a primary heat source. I was provided the opportunity by Influenster to install & use this air conditioner for free in exchange for an honest review. I can honestly say this Keystone AC unit is a fantastic little unit that provides a tremendous amount of cooling for such a small unit & it is also very quiet . Great AC & a great buy!!

Weird plug situation

6 days ago
The air conditioning and heat on this unit work well. But it wouldn’t replace an entire heating system. Works perfect for us when we use our garage as an added living space though. The major downside is that it requires a specialized outlet which is not easily accessible in most homes.

Good size & design. Hopefully it keeps both ac’s running and doesn’t break the electric circuit. Summer essential for indoors to survive the heat
