What Muncie Is Saying
Real reviews from real homeowners.
"We couldn't be happier with Joe and DeHaven's Cornerstone. Service is always prompt, he keeps our system running at peak efficiency, and he's responsive every single time we reach out. It's rare to find someone this dependable — Joe treats your home like it's his own. Highly recommend to anyone in the area."
"Furnace quit on a Sunday night in January. He answered the phone, showed up, and had heat restored before midnight. You can't ask for more than that."
"Got a second opinion after another company told me I needed a whole new system. Turned out it was a simple fix. Honesty like that is rare — highly recommend."
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 — our team — 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.
