What We Service

The full HVAC stack — residential, heat & cool.

Lester and the crew handle every part of a home comfort system: AC repair and replacement, gas / oil / electric furnaces, heat pumps, boilers, ductwork, thermostats, and humidity. All makes and models. One number, one truck, one bill.

Real Work, Real Diagnostics

What a call to Ohio Valley actually looks like.

Most of what we do isn't glamorous — it's a flame sensor, a capacitor, a leaking line set, a thermostat wired wrong by a flipper. Here's the kind of work that fills our days across Brown County and east Cincinnati.

Why Ohio Valley

Three reasons your neighbors keep calling Lester.

Locally Owned in Brown County

We're not a franchise dispatch out of Cincinnati. Lester lives here. He answers his own phone. The truck you call is the truck that shows up — every time.

1Owner-Operated Crew

True 24/7 Emergency Service

Furnace dead at 2am in January? AC quit during a July heatwave? You're not getting an answering service. Lester picks up — and if a same-night truck makes sense, that's what you get.

All Makes & Models

Carrier, Trane, Lennox, Goodman, Bryant, Rheem, American Standard, York, Heil, Amana, Coleman, Daikin — we service them all. We won't push you to replace what can still be repaired.

How It Works

Four steps from phone call to comfort restored.

01

Call Lester

One number, day or night: (513) 383-9515. You get a real person — not a call center routing you to the next zip code.

02

Free Estimate

For repairs, you get a flat price before any wrench turns. For new installs, you get a full written estimate after a walk-through.

03

Same-Day Service

Typical no-heat or no-cool calls in Mt Orab and surrounding Brown County get a same-day visit. Neighboring counties: same- or next-day.

04

Stand Behind The Work

We don't disappear once the truck pulls away. If the fix didn't fix it, we come back. That's how a one-man shop earns its name.

Brown County is home. We cover seven counties.

Mt Orab is the flagship — but our regular routes carry us across Clermont, Highland, Adams, Warren, Clinton and the east side of Hamilton County (Williamsburg, Bethel, Batavia, Amelia, Goshen, Loveland). If your zip code touches any of these, you're on the route.

Frequently Asked

Straight answers to the questions we get every week.

Do you do 24/7 emergency HVAC calls?

Yes. Lester answers nights, weekends, and holidays. When the AC goes out in July or the furnace dies in January, you get a live person on the phone — not an answering service rotating you to another contractor two counties over.

Do you service all makes and models?

Yes. We service every major HVAC brand: Carrier, Trane, Lennox, Goodman, Bryant, Rheem, American Standard, York, Heil, Amana, Coleman, and Daikin — and the off-brand stuff older homes are full of. We won't push you to replace a system that can still be repaired.

Do you offer free estimates on new installs?

Yes — every new install gets a full written estimate before any work begins. We walk the equipment, the ductwork, and the load with you so the number you see is the number you pay. No upsell games, no last-minute add-ons.

How fast can you come out for a no-AC call in summer?

Typically same-day across Mt Orab and the rest of Brown County. Clermont, Highland, Adams, and the closer parts of Hamilton County are usually same- or next-day, depending on the call volume that morning.

Do you handle boilers and old furnaces or just new equipment?

Both. We service old boilers, gas and oil furnaces, and heat pumps. We install new equipment when it's the right call — and we tell you when it isn't. A lot of houses out here have boilers older than the people living in them; we keep them running.

How far do you travel?

Brown County is home base. We run regular routes through Clermont, Highland, Adams, Warren, Clinton, and the east-Cincinnati side of Hamilton County — Williamsburg, Bethel, Batavia, Amelia, Goshen, Loveland and out to Hillsboro and Wilmington.
