Let’s get real. If you live in Stuart, Florida, your AC isn’t a luxury. It’s survival. We’re not dealing with mild summers here. We’re dealing with heat, humidity, and a climate that tests your AC system almost every day of the year.
We know because we live here, too. And at Air Plus, we’ve been fixing and installing ACs in Stuart and the Treasure Coast long enough to spot patterns. So let’s break down the most common AC problems we see in this area, why they happen, and what to do about them.
1. Weak Airflow
What it feels like:
The AC is on, but your house still feels muggy and hot. Air is coming out of the vents, but it’s barely moving.
What’s going on:
Weak airflow usually means your system is being strangled somewhere, like a dirty air filter, blocked ducts, or a failing blower motor. In Stuart, filters get clogged faster because of the high humidity and pollen. If you haven’t changed yours in a while, there’s a good chance that’s the problem.
What to do:
Check your air filter first. If it looks like a lint trap from a dryer, change it. Still no airflow? Time to call us. We’ll check for duct leaks, blower issues, or mold buildup in the system.
2. AC Not Cooling Enough (or At All)
What it feels like:
You set the thermostat to 72, but it’s stuck at 78. You keep dropping the temp, but nothing changes.
What’s going on:
In Florida, your AC runs a marathon every day. That puts wear on major parts like the compressor or refrigerant lines. Common reasons for this issue include low refrigerant (a leak), dirty coils, or a bad thermostat. Also, older systems can’t keep up with today’s heat.
What to do:
If it’s blowing air but not cold, you probably have a refrigerant or coil issue. Don’t try to DIY this—you’re dealing with pressurized chemicals. We can diagnose it quickly and give you real options, not upsells.
3. High Humidity Indoors
What it feels like:
It’s cool inside, but everything still feels damp. Clothes take forever to dry, and you feel sticky even with the AC on.
What’s going on:
In Stuart, humidity is part of life. But your AC should help manage it. If it’s not, you might have the wrong system size, or your unit isn’t running long enough to pull moisture out of the air. Another possibility: your evaporator coils are dirty and not doing their job.
What to do:
Have us check the system size and inspect the coils. Sometimes adding a dehumidifier to your HVAC system is the best move, especially in coastal Florida, where 90% humidity isn’t unusual.
4. AC Constantly Turning On and Off (Short Cycling)
What it feels like:
Your AC turns on, runs for a minute or two, then shuts off. Then it starts again… and again. It’s driving you nuts—and it’s not cooling right.
What’s going on:
This is a performance killer. The usual causes? An oversized unit (yes, bigger isn’t always better), a bad thermostat, or dirty condenser coils. Short cycling wears out your system way faster and jacks up your energy bill.
What to do:
Let us run a diagnostic. We’ll see if your unit is too big, needs a tune-up, or if there’s a control board issue. Whatever it is, we’ll tell you straight and fix what needs fixing—no fluff.
5. Strange Noises or Smells
What it feels like:
You hear banging, buzzing, or squealing. Or maybe you smell something musty or burning when the AC runs.
What’s going on:
Unusual noises often mean loose parts, electrical problems, or a dying motor. Bad smells? It could be mold, mildew, or overheating components. With Florida’s moisture levels, mold inside the air handler is more common than most people think.
What to do:
Turn off the unit and call us. Noises and smells are warning signs—ignoring them leads to bigger (and more expensive) problems. We’ll figure out if it’s electrical, mechanical, or microbial and take care of it.
6. Water Leaks Around the Unit
What it feels like:
You see water pooling around your indoor unit or dripping from the ceiling.
What’s going on:
In high-humidity zones like Stuart, your AC pulls a lot of moisture out of the air. That moisture drains through a condensate line. If the line gets clogged or the drain pan is cracked, water backs up and spills out.
What to do:
If you see a leak, shut off the unit and call. We’ll flush the drain line and check for deeper problems. A small leak today turns into ceiling damage tomorrow. Don’t wait.
7. Spiking Energy Bills
What it feels like:
Your bill goes up by 30%, but your usage hasn’t changed. The house doesn’t even feel that cool.
What’s going on:
Your AC is working harder than it should. This could be due to dirty filters, refrigerant loss, or a failing part like the capacitor. In other cases, it’s just an old, inefficient unit trying to keep up with Stuart’s brutal summer heat.
What to do:
First, change your filter. Still high? Call us. We’ll test the system, check the refrigerant charge, and let you know if you’re better off repairing or replacing. No pressure, just facts.
Bonus Tip: Routine Maintenance Is Everything
You don’t wait until your car engine explodes to change the oil. The same logic applies here. Twice a year, ideally before summer and winter, get your AC inspected and tuned up. We check refrigerant levels, clean coils, flush drains, and test components, the stuff that keeps your unit running right.
We offer a maintenance plan that pays for itself by helping you avoid breakdowns, cut energy costs, and extend your system’s life. Most of the big problems we listed above? They start small and get worse because no one’s looking.
