Lifemaster 14,000 BTU Dual Hose Portable Air Conditioner for 600 square feet rooms with 3 Operation Modes Dehumidifier, Cooling, and Fan, Suitable for Home, Office, School, & Business Rooms

I purchased the 14,000btu dual hose air conditioner for the first floor of our home. It is about 700 sqft. This air conditioner cools the entire floor. The living room, kitchen, and bathroom all to 76 to 78 degrees comfortably. I went with lifemaster brand because I previously purchased 2x 8500s for two of the bedrooms and I love them. This 14000 tu dual hose didn't disappoint. It is quite strong. It cools the entire floor. You do have to cut the window plate for standard windows which isn't a big deal. The larger until doesn't cut off after reaching the temperature set. It does seem to lower the speed and switch to a fan but the display doesn't change. After using in 90+ degrees temperatures I have found that I love it. This is coming from someone that had central air for 20 years. The entire floor feels the same temperature. I can't speak to longevity yet but I am hoping that this beast lasts because I love it. I picture it next to our sofa to show it is large. The 8500s are a ft smaller. The larger size has significantly larger power.

Works well but I have a feeling it won’t make it through the summer. Started buzzing LOUD as soon as it hit 90 out (purchased in March)

I changed the rating, because customer service from LifeMasters was excellent. Although Unit failed 7 days after the return date!, direct customer service from LifeMasters was great. Quick and easy. They send me a replacement. However the dual hose was on back order, So they send me the single hose version. Being now in a heat wave (105) I excepted the unit.
