Rich Air installed a split air conditioner in three bed rooms a year ago. Two rooms had 6000 BTU's and the 3rd had 9000 BTU's. I was offered Panasonic units for about $1000 less, but opted for Mitsubishi as they offer a 7 year warranty. The workers are clean cut and very respectful. I was amazed that they went above and beyond what I expected. Workers put down plastic all over the house even in areas I did not think was needed. The service this company offers I think of 5th Av. No hidden costs and no pressure. Workers cleaned up after themselves. I am really amazed at how everything was done correctly. I always expect contractors to cut corners but not Rich Air. They did everything correctly.
