First confirm that power has returned and the thermostat has a normal display. Check for obvious signs of water damage, burning smells or repeated breaker trips without touching wet or damaged electrical equipment. If the system still will not cool, turn it off and request qualified HVAC or electrical help.
Put household safety ahead of troubleshooting
Power outages can happen during storms or high-demand weather, when indoor temperatures may rise quickly. Ready.gov advises going to a community location with power if heat is extreme and making a plan for people who rely on powered medical devices or refrigerated medicines. A non-cooling system is not just an inconvenience for every household.
If there is standing water, storm damage, sparking, smoke or a burning smell, do not touch the HVAC unit or wet electrical equipment. Follow emergency guidance and contact the appropriate utility, electrician or emergency service as needed.
Simple checks you can make without opening equipment
Verify that the rest of the home has power and that the thermostat display is on. Check whether the thermostat is set to cooling and whether it shows an unexpected schedule setting. If you can do so safely, observe whether the indoor or outdoor unit runs, whether airflow is present, and whether a water leak is visible.
Do not repeatedly reset a breaker that trips again, bypass a safety switch, or open electrical compartments. Those are clues to share with a qualified professional. If a utility outage is still underway, equipment cannot be fully assessed until safe, stable power is restored.
What to tell the service team
Share your city or ZIP, when the outage started and ended, whether the thermostat is on, whether air is moving, and any water or unusual smell. Mention if the issue began immediately after power returned. Clear details help the team prioritize a safe next step without guessing at a diagnosis over the phone.
In Miami-Dade, Broward and Palm Beach, storm conditions can affect many homes at once; actual scheduling and service availability must be confirmed with the business. This guide does not promise emergency dispatch or a response window.
Prepare before the next outage
Ready.gov recommends keeping devices charged, planning for power-dependent medical needs, and avoiding unsafe generator use. Generators belong outdoors and away from windows, doors and attached garages; never run one indoors to power cooling. Arrange routine HVAC maintenance during normal conditions so you understand the system’s condition before the next severe-weather event.
If your AC is not cooling after stable power returns, seek a qualified diagnosis. Once Cold Supplies has a verified phone number and connected intake process, those channels can help you communicate the symptoms clearly.
Frequently asked questions
Should I keep resetting an AC breaker after an outage?
No. If a breaker trips again, stop resetting it and ask a qualified electrician or HVAC professional to investigate. Do not touch wet electrical equipment.
Can I run a generator indoors to power the AC?
No. Ready.gov says generators must be used outdoors and away from windows, doors and attached garages because of carbon monoxide risk.
