Built on a Foundation of Trust
DeHaven's Cornerstone was founded on a simple belief: folks deserve an HVAC company that shows up, tells the truth, and does the job right — the kind of company you'd send your own family to.
Hi, I'm Joe DeHaven.
I started DeHaven's Cornerstone Cooling & Heating for one simple reason: I believe folks deserve an HVAC company that shows up, tells the truth, and does the job right — the kind of company I'd send my own family to.
With 56 years of hands-on experience across furnaces, air conditioners, heat pumps, and indoor air systems, I've seen just about everything Indiana weather can throw at a home. I'm not on every call anymore — my technician, Nic, is out earning your trust the same way I do — but when you call Cornerstone, someone always answers, so your call never goes to voicemail. And I stand behind every job we do.
Your home is one of the biggest investments you'll ever make. Comfort shouldn't be complicated, and it shouldn't cost you your trust. Let's build something that lasts.
