i had called regarding a twongo deal to see if they serviced a high efficiency unit, all in one. i expected a call back that day, but did not get one, the deal was over when they called me back. they had no idea what a high efficiency unit was. i gave then the name of the unit, etc. and still did not know. most businesses of this type do work on these types of units. these units are in high end houses, most of the time. when i got the returned call, i was told only 1 person knew abt this type of unit.. knowing this, made me leary of someone working on this unit, when only one person said they knew abt it. sorry to say, i was not happy, i was impressed with the reviews that i had read regarding this company.
