How much does emergency HVAC service typically cost per hour?

Emergency HVAC service is typically billed at an after-hours premium hourly rate, with the final price confirmed after an on-site diagnosis. Rates are higher than standard visits because 24/7 staffing, rapid dispatch, and immediate parts sourcing add cost. We offer 24/7 emergency response with same-day or next-day service for AC, heating, water heaters, and duct sealing, and we frequently help homeowners in the Wellesley area. In true emergencies we restore safe heat or cooling first, then return for fine-tuning once the system is stable.

What usually affects the hourly price and first bill:

• After-hours or holiday surcharge plus a minimum dispatch/diagnostic charge
• First-hour labor rate that may differ from subsequent hours
• Parts, refrigerant, and specialty materials priced separately
• Travel time policies and the urgency level requested

If you have no heat or cooling, turn the system off and request emergency service to avoid further damage.
