How much does emergency furnace repair cost for a no-heat issue?

Emergency furnace repair for a no-heat issue with Diamond Heating and Cooling starts with a $79 diagnostic, and the final repair price is set only after we identify the exact cause. Most no-heat emergencies come from a failed part or an electrical/safety control problem, and we give you an exact price upfront before any work begins.

Our technician performs a full-system assessment, explains your options, and completes repairs only with your approval. Technicians who handle winter no-heat calls across the Treasure Valley, including Nampa, bring local know-how that speeds accurate diagnosis. If your furnace is nearing end-of-life or needs repeated fixes, we’ll compare repair versus replacement so you can decide with clear numbers. Silver Club members receive a reduced $49 diagnostic and 20% off repairs.

If you suspect a gas leak, leave the home immediately and call 911 before seeking service.
