    We thought our condenser was a goner. & we were preparing for the worst. Called our trusted Tri-County this morning & Kendall came out just now to find it was only a reset button. Thank you!!

    Consistently exceptional service. I’ve used them for regular maintenance since I moved here in 2011. And just had them replace my whole house system - they did an excellent job following up to make sure everything was done correctly.

    I have been a customer of this great company for over a decade and they are always dependable, reasonable and friendly! I came home from being away for a weekend to a house that was HOT!.
    I called Tri County A/C. Monique sent Kendall over to diagnose the problem, he fixed it and had me back with cool air in less than an hour. From the time I called. On a Friday afternoon. That’s the service with a smile part. I won’t go anywhere else. Thank you, Monique and Kendall!!
