Every part of the comfort system. All makes. All models.

Ohio Valley Heating & Air handles the full HVAC stack from a single Mt Orab, OH shop. We diagnose and repair what's there before we ever suggest replacing it — and when it does need to be replaced, the estimate is in writing before any work begins.

Heating & Furnace Service

Gas, oil, electric, and heat pumps — if it heats the house, we work on it. A lot of furnaces out here in Brown County are 15+ years old. They usually have at least one more season in them if you let us clean them right.

Annual cleaning, no-heat diagnosis, ignitor and flame sensor work, blower motors, and full replacement installs when it really is time.

Boiler Repair & Rebuilds

A lot of older homes in southern Brown, Adams, and Highland still run on hydronic heat. We work on them. No-heat diagnosis, circulator pumps, expansion tanks, pressure relief, leak repair — and the kind of patient rebuild work newer contractors won't touch.

If it's a gas, oil, or older cast-iron boiler, bring it. We'll tell you straight whether it has another five years or whether it's time to switch over.

  • Expansion tanks
