Emergency AC Repair: What to Do When Your AC Dies at 2AM

1. What to Check Before You Call

Some AC "failures" aren't equipment failures — they're settings or simple issues you can resolve yourself. Work through these quickly before calling:

If none of these reveal an obvious fix, call. You've already done the useful diagnostic steps a homeowner can do.

2. When to Call Right Now (Don't Wait)

Some situations warrant an immediate call without working through the checklist:

• Anyone in the home is elderly, very young, has heart disease, respiratory conditions, or medications that affect heat tolerance
• The temperature in the house has already climbed above 85-90 degrees
• It's a peak summer night and outdoor temperatures will stay above 80 all night
• You smell burning — electrical burning means turn off the breaker and call immediately
• There's water actively leaking from the air handler into the ceiling or walls

Heat illness is a real risk in Alabama summers. Don't be stubborn about waiting until morning for vulnerable household members.

3. What to Do While Waiting for the Tech

The hour or two between calling and arrival is the hard part. Here's how to manage it:

Move to the lowest floor

Heat rises. The first floor, and especially a basement if you have one, will be significantly cooler than upper floors. Set up in the coolest space available and keep people there.

Turn off the AC system

Turn the thermostat to OFF rather than leaving it running and trying to cool. A struggling system that's failing can cause additional damage if it keeps cycling. The tech will evaluate it fresh.

Manage windows strategically

Open windows only if outdoor temperature has dropped below indoor temperature — this is usually true after midnight, especially in fall and spring. In peak summer at midnight, outdoor temps may still be 80+ degrees, in which case opening windows makes things worse. Check the outdoor temperature before opening up.

Fans and ice

A box fan pointed at a large bowl of ice creates a surprising amount of cooling effect — more than the fan alone. If you have portable fans, deploy them with ice if available. Keep fans blowing across people, not just circulating hot air.

Stay hydrated

Drink water. Avoid alcohol and caffeine, which are diuretics. Cool (not ice cold) water is most effective for hydration.

Know when to leave

If you have vulnerable people in the home — elderly, infants, people with medical conditions — and the house is already above 85 degrees with several hours until the tech arrives, go somewhere cooler. A hotel, a family member's house, or even a 24-hour store. The tech can call you when they're close and you can return for the repair. There's no award for staying in a hot house.

4. What to Tell the Technician When You Call

The more useful information you can provide, the faster the diagnosis goes. Have this ready:

• Your address and any access or gate information
• Make and model of your HVAC system (usually on a label on the outdoor unit)
• Age of the system if you know it
• What symptoms you're seeing — not cooling, making unusual noises, breaker tripping, water leaking
• When it started
• Whether anything happened before it failed — power outage, storm, recent service
• Whether anything you can see looks unusual — outdoor unit not running, ice on lines, water on floor
• Whether anyone in the home has medical conditions that make heat urgent

5. What to Expect When the Tech Arrives

Here's the honest version of what a legitimate emergency service call looks like:

The technician will do a full diagnostic before quoting any repair. This means checking voltages, measuring refrigerant pressures, testing components, and understanding the full picture before recommending a fix. This should take 20-45 minutes. If someone shows up and tries to sell you a repair after 5 minutes of looking around, be cautious.

A good tech will tell you exactly what they found, what it means, what it will cost to fix, and whether the repair makes sense given the age and condition of the system. They'll give you a firm price before starting any work.

Most common repairs — capacitor replacement, contactor replacement, refrigerant recharge — can be completed the same visit when parts are on the truck. Parts for less common failures may need to be ordered, in which case you may be without AC for another day. Ask directly if parts are on the truck.

6. After the Repair: Preventing the Next Emergency

Once you're cool again and the adrenaline has worn off, have a real conversation with the technician about what caused the failure and what the system's overall condition is. Ask:

• Was this failure preventable with maintenance?
• Are there other components showing signs of degradation?
• What's the overall condition of the system — is it worth continued investment?
• When should I schedule my next maintenance visit?

Most overnight emergency calls could have been prevented with a spring maintenance visit that caught degrading components. A capacitor failing in July was usually 60% of its rated value in April. An annual maintenance visit in spring is significantly cheaper than even a single emergency call — and far less stressful.

See our HVAC maintenance page to schedule before next summer. We'd rather see you then than at midnight again.
