Excellent Customer Service for a very good unit.  It does the job.
5 Stars
Excellent Customer Service for a very good unit. It does the job.
I ordered this dehumidifier in hopes of reducing the humidity in our crawl space. I really like the internal pump so it can easily send the water to an outside drain. The unit shut off within a couple of weeks of installation. Eileen at Aloaire support was excellent in responding very quickly (by email) and guiding me through troubleshooting the unit. When the final test pointed to a failed component, she made arrangements for a return and replacement. The replacement has been operating very well for several weeks now. Our crawl space area was at the upper end of the range for this unit. It has kept the crawl space at the setpoint (55%) with ease it seems. I can hear it cycle on and off, which is comforting. Nice!
