Owner-operated in Brown County — not a franchise.

Ohio Valley Heating & Air is run by Lester Arnett out of a shop on Mount Rd in Mt Orab. One owner. One phone number. The truck you call is the truck that shows up — and the guy under your house is the guy whose name is on the door.

About Lester

The guy who answers the phone is the guy doing the work.

Ohio Valley Heating & Air is owner-operated by Lester Arnett. We're not part of a regional roll-up or a Cincinnati franchise — we're a local Brown County HVAC shop based out of Mt Orab on Mount Rd. When you call (513) 383-9515 you're getting Lester or someone Lester trained personally.

The shop services every make and model of residential heating and cooling: AC, gas furnaces, oil furnaces, heat pumps, boilers, and the older stuff that flippers won't touch. We work on Carrier, Trane, Lennox, Goodman, Bryant, Rheem, American Standard, York, Heil, Amana, Coleman, and Daikin equipment.

Around-the-clock emergency service is the part most clients lean on. Furnace dies at 3am in January, AC quits during a heatwave — that's when "locally-owned" stops being a marketing line and starts being a guy answering his phone.

How We Operate

Three things we won't budge on.

01 / Diagnose First

Repair Before Replace

Most HVAC systems out here have more life in them than a sales-driven contractor will admit. We diagnose the actual fault before we ever quote a replacement. A $40 capacitor or a flame sensor wipe is sometimes all that stands between you and another five years on the system you already paid for.

02 / Show Up

One Number. Real Person.

You call (513) 383-9515 — day or night — and you get Lester. No answering service routing you to whichever subcontractor's truck is closest. Same truck on the diagnosis. Same truck on the repair. Same name on the invoice.

03 / Stand Behind It

Stand Behind The Work

If the fix didn't fix it, we come back. That's how a single-owner HVAC shop in a small town earns its name — there's nowhere to hide. Free written estimate on new installs. Flat-price diagnosis on repairs. No surprise math at the end.

Talk To The Owner

Skip the call center. Call Lester.

Whether it's a 2am no-heat call or a planned install in spring — one number, one truck, one bill. Free estimates on new installs across Brown County and east Cincinnati.
