Testimonials & A Few of Our Top Brands!


  • Dear Randy, I appreciate your prompt service. The installation looks great. Again thanks, Jay Bealer.
    Jay Bealer
  • Called on Friday for next Monday service and I was grateful for them to squeeze me in. He grabbed a new part from his truck for my AC unit and fixed the small problem even though we didn't ask/expect him to as we ordered the service call for inspection only. He could have not done anything and waited for us to call him back for another service call. I'd recommend their service
    Sarah Tolouse

    Austin Brawner
  • I went through some really unfortunate circumstances this year. I still owed a balance to Cantrell’s for some work they did and instead of making my life harder, they worked with me in regards to the bill I still owed. I appreciate their patience and understanding on paying my account off. I had to use a large part of my tax refund to pay for a family member’s funeral. I am forever grateful that they have worked with me during this difficult time. Their efforts and understanding will not go unnoticed.
    Joshua Gavin
  • As always, prompt service, knowledgeable techs, fair prices. I'm closing on 2 more duplexes next Friday... 4 more units for them to maintain!
    Pete Winters
