24/7 Emergency AC Service
AC down in the heat? We dispatch licensed technicians around the clock.
No AC and 115 Degrees Outside
A cooling failure in July is not an inconvenience here, it is a real safety issue, especially for kids, older family members, or anyone with a health condition sensitive to heat. We run dispatch around the clock, including weekends and holidays, because equipment does not wait for business hours to fail and neither do we. Call with your address to discuss service and the equipment problem. Our shop is in Tempe. Keep people safe while the next step is arranged, particularly if indoor temperatures are becoming unsafe.

What Usually Causes a Middle-of-the-Night Failure
Late-night and early-morning failures are often electrical: a tripped breaker from a short in the compressor windings, a failed capacitor that finally gave out after months of stress, or a frozen coil from restricted airflow that has been building for weeks. Attic air handlers can also trip a float switch when the condensate line clogs, which shuts the whole system down as a safety measure rather than letting water back up into your ceiling. A diagnosis separates an electrical fault from an airflow or drainage problem. The parts needed and the condition of the equipment determine what the repair involves, rather than the hour on the clock.
What to Do While You Wait
Close blinds and curtains on sun-facing windows, turn off unnecessary lights and appliances that add heat to the house, and move to the coolest room, typically on the ground floor. Fans move air but do not lower room temperature. Do not rely on them as the only protection in extreme indoor heat. Move to an air-conditioned place when staying in the house is unsafe. Avoid repeatedly turning the thermostat down since that will not make the air colder and can make certain failures worse. If anyone in the house is showing signs of heat distress, treat that as the priority over the equipment and seek medical help first.
Every emergency visit gets the same upfront approach as a scheduled one: a $120 diagnostic fee that is waived when you approve the repair, and a written price before any work begins. We are a family-owned shop out of Tempe, and we would rather send a technician out at midnight than have a family sit in a hot house until morning. If replacement is needed, the estimate is free. Ask about the next available appointment and plan a safe place to stay cool while the equipment is out of service.

Frequently asked questions
What pricing will I see before an emergency repair?
Repair visits start with a $120 diagnostic, waived when you go ahead with the repair. You see the proposed repair price in writing before work starts.
How long does it usually take for someone to arrive at night?
Response times vary by call volume and location, but after-hours calls are treated with the same urgency as daytime emergencies.
What typically causes an AC to die overnight?
A tripped breaker from an electrical short, a failed capacitor, a frozen coil from restricted airflow, or a clogged condensate line tripping the safety switch are the most common causes.
Should I keep running the AC if it is blowing warm air?
No, turn the system off at the thermostat and call us. Running a struggling system can turn a cheap repair into a compressor replacement.
