Quick questions
What counts as an HVAC emergency?
No heat in winter, no cooling in summer, smell of gas, refrigerant leak, water leaking from a high-efficiency furnace, ice on an indoor coil, or a vulnerable person (infant, elderly, medical condition) in the home. When in doubt — call us. The triage takes 60 seconds.
How fast can you actually get a technician out?
Same-day for most calls during business hours. After hours, we dispatch based on severity and proximity — true no-heat-in-winter and gas-smell calls jump the queue. We'll tell you the realistic ETA up front, not a vague promise.
What do I do until the technician arrives?
If there's a gas smell — leave the house immediately and call the gas utility, then us. If water is leaking — shut the system off at the thermostat AND the electrical breaker if safe. If it's cold inside — open faucets to a slow drip on exterior walls to prevent frozen pipes. We'll walk you through it on the call.
