Know when to stop using the equipment, when to call for repair, and when immediate safety help comes first.
Call About AC RepairImmediate danger comes first. For fire, smoke, or a suspected gas leak, leave the area and contact emergency services from a safe location. An HVAC service request is not emergency response.
AC Answer 32
Move to a reliably air-conditioned place if your home becomes too hot, especially when someone is more vulnerable to heat. Arrange repair while protecting the people in the house. If someone becomes confused, loses consciousness, or shows other signs of heat stroke, call 911 and begin cooling them while help arrives. Do not wait for an HVAC appointment.
AC Answer 33
Leave the system off and arrange a qualified electrical or HVAC evaluation instead of repeatedly resetting a breaker that trips. Recurring trips can indicate an electrical or equipment fault that needs diagnosis. Keep electrical covers closed. Tell the service provider when it trips and whether the problem began after a storm or another change.
AC Answer 34
A blocked condensate drain or another drainage problem can cause water to collect or overflow. Turn off the system if it is leaking into the home, and arrange service before water causes more damage. Avoid contact with wet electrical equipment. Tell the technician when you first noticed the leak and where the water appears.
AC Answer 35
Keep flood-affected HVAC equipment off until a qualified professional has assessed it and confirmed it is safe to use. Flooding can leave contamination and damage that are not obvious from outside. EPA advises against using an affected system to dry the home before professional clearance. Follow local emergency guidance and avoid entering standing water around electrical equipment.
