TL;DR: Call for emergency AC service if you smell burning, see smoke, have water coming through a ceiling, or lose cooling on a hot day while an older adult, baby or sick person is home. Weak cooling on a mild night, or ice on the lines, can usually wait for regular hours. While you wait, turn the system off, contain any water, keep the house cool and write down what you saw and heard.
Emergency AC service is worth calling for when an AC problem puts people or your home at risk. That means a burning smell or smoke, water pouring through a ceiling, or no cooling on a hot day while an older adult, baby or sick person is in the house. Most other failures, like weak cooling on a mild night, can wait for regular hours.
This guide is for homeowners in Tavares and nearby areas like Grand Island, Paisley and Zellwood. It explains how to sort a real emergency from a problem that can wait. It also covers what to do in the hour or two before a technician gets there.
What counts as an AC emergency in a Central Florida home?
An AC problem is an emergency if it creates a safety risk, a health risk or fast property damage. If it does none of those, it is still annoying, but it can usually wait for a daytime visit.
Safety risk
Electrical trouble comes first. The Electrical Safety Foundation International lists a burning smell, discolored switches and warm outlets as possible signs of a serious wiring problem. On an AC system, that smell may come from a motor, a capacitor or a wire connection that is overheating.
Health risk
Heat is a real danger here. The CDC says people 65 and older are more prone to heat-related health problems. It advises them to stay in air-conditioned buildings as much as possible. Florida’s Department of Health tracking program notes that extreme heat events cause more deaths each year than hurricanes, lightning, tornadoes, earthquakes and floods combined. Lake County has a long cooling season, heavy humidity and many retirees and 55+ communities. Because of that, a dead AC in July is a different problem than a dead AC in December.
Property risk
Water is the other big one. ENERGY STAR warns that a plugged condensate drain can cause water damage in the house and affect indoor humidity. A drip in a pan can wait until tomorrow. Water coming through drywall can’t.
Signs you need to call a pro now
- A burning, melting-plastic or hot electrical smell from the vents, air handler or outdoor unit
- Smoke, sparks or scorch marks near the outdoor disconnect or wiring
- An AC breaker that trips again right after you reset it
- Water dripping from a ceiling or spreading across the floor
- Sudden grinding, screeching or banging (our guide to what different AC noises mean covers each sound)
- No cooling and a rising indoor temperature with a higher-risk person at home
Which AC problems can wait until morning?
Many AC problems feel urgent but can safely wait for office hours, as long as nobody at home is at high risk from the heat. Use this table to sort yours.
| Problem | Call now? | What to do while you wait |
|---|---|---|
| Burning smell, smoke or sparks | Yes | Turn the system off at the thermostat and the breakers. If you see flames or heavy smoke, get out and call 911. |
| Water coming through a ceiling or across the floor | Yes | Shut the system off, catch the water and move furniture and electronics. |
| No cooling on a hot day with an older adult, infant or medically fragile person home | Yes | Move them to the coolest room or to an air-conditioned place and keep them drinking water. |
| Ice on the copper lines or indoor coil | Usually next business day | Set the system to off and the fan to on so the ice can melt. |
| Running, but cooling weakly | Usually can wait | Check the filter and thermostat settings. See 8 reasons your AC isn’t cooling enough. |
If you’re unsure, call and describe what’s happening. A short phone call is better than guessing.
What should you do while you wait for the tech?
The most important step is to turn the system off if there is any smell, smoke, water or ice. If a damaged system keeps running, a small repair can turn into a big one. Then work through these steps:
- Cut power if you smell burning. Most split systems have one breaker for the outdoor unit and one for the indoor air handler. Turn both off. Do not keep resetting a breaker that trips. It is tripping to protect you.
- Contain water. Put towels and a bucket under the leak. Move rugs, boxes and electronics away from the air handler closet.
- Let ice melt on its own. Set the thermostat to off and the fan to on. Never chip or scrape ice off the coil or the copper lines.
- Check the filter. A clogged filter can choke airflow. If it’s dirty, swap it before the tech arrives.
- Hold on to the cool air you have. Close blinds on the sunny side, skip the oven and dryer, and pick one interior room to stay in.
- Protect anyone at higher risk. The CDC suggests an air conditioning break at a mall or library during the hottest part of the day. In rural spots like Paisley, plan that trip early instead of waiting until the house is hot.
- Write down what you noticed. Note when it started, any sounds or smells, and any thermostat error codes. Snap a photo of the label on the outdoor unit. This helps the technician diagnose the problem faster.
Skip the DIY fixes. Don’t open electrical panels, don’t spray the outdoor unit while it has power, and don’t try to add refrigerant.
How does after-hours AC service work with Lucas Air?
Lucas Air Conditioning and Heating, LLC is not a 24/7 company. But a technician is on call after hours for real emergencies. Office hours are Monday through Friday, 8:00 AM to 5:30 PM. After hours, call the main line and explain what’s happening.
Diagnostic visits are $125 for homes and $135 for commercial properties. Ask about any after-hours charges when you call so there are no surprises. If your problem passed the tests above as non-urgent, booking during office hours is the simplest route.
Business owners have their own version of an emergency. If you run a restaurant kitchen or a rental property, a dead system can mean closed doors or upset tenants. Say so when you call.
How can you make an AC emergency less likely?
Regular maintenance prevents many of the failures that turn into after-hours calls. ENERGY STAR recommends a pre-season checkup by a contractor every year. It also notes that contractors get busy once summer arrives, so spring is the best time to check the cooling system.
A precision tune-up is $125. A Preventative Maintenance Agreement is $129/year and includes one tune-up, 15% off parts and priority scheduling. Priority scheduling matters most during the hottest weeks, when everyone’s AC is working its hardest. Make sure your outdoor unit’s hurricane pad and straps are still solid, too. A unit that shifts in a storm can stress its refrigerant lines and wiring.
Snowbirds and seasonal residents should ask a neighbor or property manager to check the house during heat waves. A failure that goes unnoticed for weeks lets humidity build up inside a closed Florida home.

Frequently Asked Questions
Should I keep running my AC if water is leaking from the indoor unit?
No. Turn the system off at the thermostat so it stops making more condensation, then catch the water and move belongings away. A clogged condensate drain is a common cause, and running the system usually makes the leak worse.
Is it safe to run my AC with ice on the outdoor copper lines?
It’s best not to. Ice usually points to an airflow or refrigerant problem, and running the system that way can strain the compressor. Set the thermostat to off and the fan to on so the ice melts, then schedule a repair.
Is a loud noise from my AC an emergency?
A sudden grinding, screeching or banging sound means you should turn the system off and call, because a failing motor or loose part can cause more damage. A small change in a normal hum can usually wait for a regular appointment.
What does an AC diagnostic cost with Lucas Air?
Diagnostics are $125 for homes and $135 for commercial properties. If you’re calling after hours, ask about any extra charges before the visit is scheduled.
What if my AC fails while I’m out of state for the summer?
Ask a neighbor, friend or property manager to check the house during heat waves and give them a number to call for service. Catching a failure early limits how much humidity builds up in a closed house.
