# Urgent HVAC Service > A 24/7 HVAC contractor referral line serving five metros: Houston, Phoenix, Dallas, Miami and Los Angeles. Callers describe the symptom and their ZIP; a dispatcher matches them to an independent licensed contractor who services that equipment type in their part of the metro. Phone: (855) 644-0803. Not a contractor — a referral and dispatch line. Diagnosis, pricing and scheduling are arranged directly with the contractor. The call is free. ## Services - [AC repair](https://urgenthvacservice.com/ac-repair/): Emergency air conditioner repair — warm air, won't start, weak cooling, leaking, noisy, frozen — plus heat pump faults (reversing valve, defrost, mode).
