An HVAC emergency is any heating or cooling problem that threatens safety, causes active damage, or makes the home unlivable. The most common triggers are total loss of heat or AC during extreme weather and any sign of gas, electrical, or carbon monoxide danger. Technicians in the Treasure Valley, including Emmett, handle these calls around the clock and start with a full‑system assessment, explain the fix and price, and only proceed with your approval, backed by our written “fixed right or it is free” repair guarantee. If a breaker trips more than once, the system is signaling trouble and forcing it back on can cook a compressor.
Treat it as an emergency if you notice:
- No heat in freezing temps or no cooling in extreme heat, especially for infants, elderly, or medical needs
- Gas smell, hissing near gas lines, or a CO alarm; evacuate and call your utility/911 first
- Electrical burning smell, smoke, sparking, or repeatedly tripping breakers
- Active water leaks from the furnace, AC, or ceiling near vents
If any of these occur, shut the system off at the switch or breaker and call an emergency technician right away.

Diamond doesn’t bill emergency HVAC by the hour. You pay a diagnostic fee, then approve a fixed-price estimate before work starts. The diagnostic is $79, or $49.95 for Silver Members. Members also receive 20% off parts and labor and a guaranteed emergency appointment within 24 hours. A licensed technician performs an on-site evaluation, explains the findings, and confirms costs in writing. Service is available 24/7 across Boise, Meridian, Nampa, Caldwell, Middleton, and the Treasure Valley.
