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.

They professionally installed all three of my heat pumps over past 4 years with knowledgeable and caring qualified installers. I trust them to keep my system in top- notched condition annually, too.
