    The answering service was very polite and helpful. Scott called back within 5 minutes and arrived within a half hour of my initial call. He got the unit running and will be back to complete the repairs. I highly recommend this company.

    I love this company. Kate schedules the service and she is professional, efficient and helpful. We have the same technician which is great because he worked on the units and knows them inside out. He also knows the part for the humidifier and he knows exactly what to do.
