Good: As promised Richair's services were the best I ever received from any air conditioning company. Fast, punctual, gave me price to fix my ductless mini split air conditioner, and after repair the price did not change - kept their promise, did not give me stories and excuses, just did their job.. Bad: A little expensive compare to others. But I appreciate their service. I have received what I paid for.. Improvements: Open a showroom in our area. So far there is only one showroom of such kind.. Other: I called them to fix another contractors' mistake - another contractor installed my new ductless mini split system. It never worked right. Would highly recommend this company to everyone..
