A plan holder calling at nine at night in July is the customer we actually want - it means the two-visit rhythm caught almost everything else. The plan is two tune-ups a year, one before cooling season and one before heating season, priority dispatch ahead of the general queue, a discount on any repair we find, and no overtime rate no matter when you call.
A cooling visit in spring and a heating visit in autumn both cover the same ground: coil cleaning, a refrigerant charge check, electrical connections and a capacitor test, clearing the condensate drain, and a blower or burner inspection. On a furnace we add a heat exchanger check every time - a cracked one is a carbon monoxide risk, not a comfort issue.
A blocked condensate drain is one of the most common reasons a system shuts itself off mid-summer, and it is a five-minute fix caught during a tune-up rather than an emergency call during a heatwave.
