HVAC Tech Coffee Mug - It Was Set to Heat Funny Thermostat Mug

It was set to heat. The thermostat on this mug sits over a sunny calendar page with its tiny flame icon glowing, and the punchline wraps around to the other side in plain type.

Use it for coffee in the service van before the first call, a tea back at the shop while writing up tickets, or a desk mug for the dispatcher who heard the whole story. It is a simple thank-you for the tech who fixed the AC, or a gift for a heating-and-cooling crew. The design wraps an 11oz mug.
