What should I switch off?

If the breaker trips again, leave it off. If you smell burning, turn the system off at the thermostat and do not keep resetting it. A gas smell is a furnace problem: leave the house and call 911 or Southwest Gas.

Who is most at risk in a hot house?

Pima County’s Beat the Heat page lists infants and young children, people who are pregnant, people 65 and older, and people who are ill or on certain medications. Check on them. Do not leave anyone in a parked car.

Where are cooling centers?

Pima County maps them at pima.gov/cooling-centers and describes heat risk at pima.gov/beat-the-heat. Hours and rules are the location’s, and the county says the summer network runs about May 15 to September 15.

Is this an overnight repair line?

No. The repair request is a same-business-day callback, the same rule as the emergency AC repair page. If someone may be having heat stroke, call 911.

Which checks are safe?

Thermostat on Cool, a filter you can see through, one breaker reset, and a look from a few feet away at whether the outdoor fan is turning. Leave the electrical panel closed.

What page is the actual repair?

AC repair in Tucson. This page is the checklist.

When the air conditioner stops in Tucson, the house does not stay safe for long. Do the short checks below, then decide whether people need a cooler place while you wait on a repair. Sabino Creek’s repair request is a same-business-day callback. It is not an overnight dispatch line. If someone is confused, faint, or has hot dry skin and a strong pulse, Pima County’s heat-illness guidance says to call 911 and cool them while you wait. That guidance is on pima.gov/beat-the-heat.

Checks that do not involve tools

Thermostat on Cool, fan on Auto, setpoint below the room temperature. A system left on Heat will blow warm air on purpose.
Filter. If you cannot see light through it, replace it. A packed filter can freeze the coil or stop the airflow that makes cooling work.
Breaker. Reset it once. If it trips again, leave it off.
Outdoor unit, from a few feet back. Is the fan turning? Is the air off the top warmer than the yard? Do not open the electrical compartment and do not pressure-wash the fins.
Ice on the large copper line: turn the system off and let it thaw. Running it harder makes more ice.

People first

Air conditioning is the protection Pima County names against heat illness. A fan is not enough when the house is already very hot. Infants, older adults, people who are pregnant, and people who are sick should not wait the afternoon out in a closed house. Pima County’s cooling-center map is at pima.gov/cooling-centers. The county describes cooling centers, respite locations, hydration stations, and library cooling spaces, and says locations set their own rules. The Heat Relief Network’s mapped season is about May 15 through September 15, so check the map for what is open on the day you need it. A mall or a library also gets people into air conditioning for a few hours.

Never leave a person or a pet in a parked car.

When the house is safe enough to wait, send the form or call (520) 329-1252. The repair page is AC repair in Tucson. The shorter callback page is emergency AC repair. Longer symptom notes are on AC not cooling. Landlords reporting a rental are on HVAC for rentals.
