Ohio Climate & Code Notes
Road-salt tracking in winter and 32-inch frost lines require chemical-resistant topcoats and deep aggregate bases.
Pro Field Notes
- Garages lose heat rapidly around overhead doors; size units at 30 to 40 BTUs per sq ft and insulate doors to R-13+.
- In freeze states below 15F, select a cold-climate hyper-heat inverter unit with an integrated base pan heater.
- A dedicated 240V double-pole circuit breaker and exterior weatherproof disconnect box are required for 18k+ BTU systems.
