Total system failures don't check a calendar, and neither do we.
Phone triage happens before dispatch so the right tech and parts head your way.
If you're dealing with a total system shutdown during a freeze warning, a gas smell near the furnace, or smoke and burning odor from the outdoor unit, you already know a system failure at 2am on a holiday weekend is a genuinely different problem than the same failure on a Tuesday afternoon, and it needs a genuinely different response.

Most emergency HVAC service problems give some warning before they turn into a total system shutdown during a freeze warning, a gas smell near the furnace, or smoke and burning odor from the outdoor unit — catching it early usually means a shorter, cheaper fix.
