Stay Safe
While You Wait for Your Technician
Getting the inside temperature down as quickly as possible is the priority. A few things that help while your technician is on the way:
Close Blinds & Curtains
Block direct sunlight on south- and west-facing windows. This alone can significantly lower indoor temperature.
Turn Off Heat Sources
Ovens, dryers, and dishwashers contribute significant heat to the home. Switch them off until the AC is running again.
Move to the Lowest Level
Heat rises, so lower floors stay cooler. If you have a ground floor or basement, gather there while you wait.
Run Ceiling Fans
Set fans to counterclockwise. They don't cool the air, but the breeze makes it feel cooler on your skin.
Protect Vulnerable Family
Elderly family members, young children, or anyone with respiratory or heart conditions should move to a cooler location during the repair.
Call if Concerned
Summer heat indexes regularly surpass 100° in Clay County. An uncooled home becomes a health risk fast. Call 904-206-8702 with any concerns while you wait.
Our Emergency Process
What Happens When You Call All Set for an Emergency
Call and Get a Real Person
When you call 904-206-8702, someone answers directly. Not a voicemail, not an answering service that takes messages. You explain what's happening, and All Set sends a technician to your home.
Your Technician Diagnoses on Arrival
Your technician arrives, assesses the system, and explains exactly what has failed and why — in plain language, before any work starts. If there are multiple options, you hear all of them. If the repair doesn't make sense given the system's age, you hear that too.
Most Repairs Completed the Same Visit
All Set technicians carry the most commonly needed parts for Florida residential emergencies — capacitors, contactors, and other high-failure components. Most emergency calls are resolved on the first visit. If a part needs to be ordered, you'll know before the technician leaves.
Why Clay County Chooses All Set
Live Dispatcher 24/7
No answering service, no voicemail queue. A real dispatcher picks up day or night.
Fully insured HVAC contractor
Full general liability and workers' compensation insurance in the state of Florida.
Don't Wait
Why Waiting Makes an AC Emergency Worse
A system that fails due to a worn capacitor or low refrigerant is a manageable repair if addressed quickly. Left in a compromised state, the same failure can damage other components — especially the compressor, the most expensive part to replace. What begins as a $150 repair can escalate to a $1,200 repair or require a full system replacement if the system continues to struggle while you wait for a weekday appointment.
Beyond the equipment, there is the human cost. Sleeping in a home without AC during a Northeast Florida summer is miserable for healthy adults and truly dangerous for anyone who is elderly, very young, or has a health condition. Getting the repair done tonight is almost always the better choice.
