  • “We had Kason do extensive repairs on the air conditioning units at our Child Care Center. He was on time, professional and gave an excellent quote which he stuck to. He was fair, honest and kept us in the loop throughout the whole process. We will definitely be using him in the future.”

    — Sarah B.

  • We needed a walk-in freezer repair at our catering business—Kason was there on Wednesday to investigate, called me the same day with an estimate, and we had the install on Friday. I know we are a CRS Mechanical customer for life now.

  • “Our technician, Connor, was fantastic! From start to finish, I couldn't be happier with their communication, promptness, and professionalism. I tried calling all the 'big' companies first, but I couldn't be happier that their wait lists were weeks out because we found our new go-to company!"
