Richair installed 2 split-ductless a/c units during townhouse renovation a few years back. We called 2 other HVAC contractors prior to Richair. When we described the project on the phone, we were told that it would cost $10,000-12,000 to do the project and options were not raised... When we called Richair and spoke to Fred, he said there were different options we could consider. He came to our house and said that we could get by with 2 units, as long as we were willing to keep the door open to a small room in the center of the apartment. He also offered us as a $1000 discount on a Sanyo compressor paired with Panasonic blower units. He said Panasonic had taken over Sanyo and would eventually change the labeling on future compressors. The installers were competent, professional and clean. The system works very well and is more than adequate to cool the apartment.
