Emergency Service FAQ
An HVAC emergency is any situation that poses a safety risk or could cause significant damage if not addressed immediately. This includes complete system failure during extreme weather, gas leaks or carbon monoxide concerns, burning smells, water leaks causing damage, frozen pipes, or no heat in freezing temperatures. When in doubt, call us - we're happy to help you assess the situation.
Our typical emergency response time is 1-2 hours, depending on your location and current call volume. We prioritize true emergencies (no heat in freezing weather, safety concerns) and work to reach you as quickly as possible. Our dispatchers will give you an estimated arrival time when you call.
We maintain transparent, upfront pricing for all services. While emergency calls may have different rates than scheduled appointments, we always provide the full price before starting any work. You'll never be surprised by hidden fees or after-the-fact charges.
For safety: if you smell gas or burning, leave the house and call us from outside. Otherwise, turn off your system at the thermostat to prevent further damage. For no-cooling emergencies, close blinds, use fans, and stay hydrated. For no-heat emergencies, use safe portable heating and layer clothing. Our dispatcher can provide specific guidance for your situation.
