  • "Richair Comfort Solutions were very professional and knowledgeable..."

    I contacted several companies for an estimate to install new ductless air conditioning system. I found Richair Comfort Solutions; they were very professional and knowledgeable. Their product specialist spent a lot of time explaining the differences in ductless systems available today. I took their advice and I am really happy with my new ductless system.
