I've had it running for a few weeks and it was tested pretty well yesterday when the temp got up to 93. It was able to maintain a set temp of 79. The tall ceiling was the unknown factor when I tried to calculate how much cooling I needed. The calculators had me in the 12,000 to 14,000 BTU range with normal height ceilings and insulation. I did not want to over do it as the dehumidifier function was important. If the unit is too powerful, it cycles too often and results in cool and damp air. I also use a few fans in the shop and the combination has kept me comfortable so far. If I'm doing aerobic activitees I can turn it down a few degrees.
The dehumidifier part of it works very well. The unit has a pump that circulates the condensate back up from the bottom tray and it assists in cooling the condenser when it vaporizes and is exhausted outside. If the condensate accumulates faster than it can be vaporized, the overflow runs out a 1/4" Tygon hose I was able to squeeze through the weatherstripping at the bottom corner of the back door.
I had researched these and the Mini-Split units and this was about 1/4 the cost after installation. If it holds up for a couple of years I'll be happy. There are 14,000BTU dual hose portable units on the market but they were in the $700 range and not available locally. If this doesn't work I can return it for my money back. BJ's works like Costco...they will take back anything...well dirty Pampers may not work:roll:... but this will be no problem.
