"called RSI to get a quote on an air conditioner for my rental property, they were a little higher priced than my lowest bid. I went with the low bidder and paid a hefty price. After the company installed my unit, and took my money my renter smelled a strange odor from the crawl space!  I couldn't get them to answer the phone and I didn't know what to do. I called Randall from RSI and he came out and told me they had done such a poor job installing my furnace that it was unsafe to use it. The furnace was leaking fumes underneath my house because they didn't even put the right vent on it!  I told Randall to take the unit out and to install one properly.  RSI  removed the old unit, and properly installed a new one for me. I'll never use another company again! Lesson learned."

Glen G. of  Moorseville, NC

"We live in Mooresville, NC, northwest of Charlotte, NC. We recently called RSI Carolina, Inc. to request service on our air conditioning unit. Everyone we spoke to was extremely helpful and truly cared about our concerns. Unlike many of the companies in Charlotte, they were very professional and willing to make sure our out of pocket expense was as minimal as possible. When visiting our home, they showed up earlier than expected, which is a plus
around here because other companies give you an estimated time and show up
much later than their commitment. The technicians were like technical
trainers, very knowledgeable, courteous and willing to bend over backwards to save us money. My wife really appreciated that! We have shared our satisfaction with neighbors and co-workers. We would recommend RSI Carolina,
Inc. to anybody. They are like the hometown company that is not from our town! Thanks and job well done RSI Carolina, Inc."
