Common AC Problems Flow Pros Repairs
Most Florida AC failures come down to a handful of common issues. Here’s what we see most often in Pinellas County homes — and what a Flow Pros tech can typically handle on the first visit:
AC Running But Not Cooling
The unit is on, the fan is spinning, but warm air is coming out of the vents. Usually caused by low refrigerant (a sign of a leak), a dirty evaporator coil, a failing compressor, or a frozen coil from restricted airflow.AC Won’t Turn On At All
Thermostat calls for cooling and nothing happens. Common causes: blown capacitor, failed contactor, tripped breaker, bad thermostat, or a safety switch that’s tripped from a full drain line.AC Freezing Up
Ice on the copper lines or the indoor coil. Usually caused by airflow problems — dirty filter, blocked return, failing blower motor — or low refrigerant. We thaw, diagnose the root cause, and repair.Water Leaking From the Indoor Unit
Most common cause in Florida: a clogged condensate drain line. Bacteria and algae build up fast in our humidity. Less commonly, a cracked drain pan or frozen-then-thawed coil. We clear the line and pressure-test the system.Strange Noises
Grinding, squealing, buzzing, or clicking. Each sound points to different failures — worn blower bearings, a failing contactor, a loose fan blade, or a dying compressor. We diagnose by sound and confirm with instruments.High Humidity Indoors
Your AC is cooling but the house still feels clammy. Often a sign the system is oversized, the blower is running too fast, or the unit needs a tune-up. Sometimes it’s a job for a whole-home dehumidifier.AC Cycling On and Off Rapidly
“Short cycling” kills compressors and spikes your electric bill. Causes include a dirty filter, a refrigerant leak, a failing thermostat, or an oversized system that was never properly matched to the home.High Electric Bills
A sudden jump in your Duke Energy bill without a sudden jump in weather usually means the AC is working harder than it should — failing capacitor, dirty coils, low refrigerant, or a system that’s simply reaching end of life.Recognize any of these?

Before You Call: 3 Things Worth Checking
Sometimes an AC “failure” is a 30-second fix. If your system just stopped cooling, try these three checks before booking a service call — we’d rather save you the diagnostic fee if it’s something simple.
1. Check the thermostat
Is it set to COOL (not just “fan on”)? Is the temperature set below the room temperature? Are the batteries fresh? We’ve driven to plenty of service calls that ended with a $4 battery swap.
2. Check the breaker and the outdoor disconnect
The AC has two power sources — a breaker inside the electrical panel, and a disconnect switch on the wall next to the outdoor condenser. A tripped breaker is a common cause of “sudden” AC failure. If it trips again after resetting, stop — that’s a real electrical problem. Call us.
3. Check — and replace — the air filter
A filter choked with dust restricts airflow enough to freeze the indoor coil solid. Once that happens, your AC won’t cool at all until it thaws (4–6 hours). If your filter looks gray, swap it. If you see ice on the copper lines at the indoor unit, turn the system off, switch the fan to “on” to speed the thaw, and call us before turning cooling back on.
Still not cooling after those three checks? That’s when it’s time to bring in a tech. Call Flow Pros at 727-265-9639 or book a service call online.
What Happens When You Call Flow Pros for AC Repair
- You call or book online. A real person — not a bot, not an out-of-state call center — answers. We confirm a service window (usually same-day) and dispatch a licensed HVAC tech.
- Your tech arrives in a fully stocked truck. Our service trucks carry the parts that fail most often in Florida: capacitors, contactors, fan motors, float switches, common refrigerants, and more. We don’t drive away to go get parts if we don’t have to.
- Diagnosis and upfront quote. The tech inspects the system, identifies the issue, and gives you a written, flat-rate quote before any repair work begins. You’ll know exactly what it costs — no hourly-rate surprises, no “while I’m here” add-ons.
- Repair — typically same-day. About 9 out of 10 AC repairs we quote are completed on the first visit. We clean up when we’re done. You get cold air back the same day you called.
- Follow-up and guarantee. Questions after we leave? Call us. Every repair is backed by our 100% satisfaction guarantee and any applicable manufacturer warranties on the parts we installed.
How Much Does AC Repair Cost in St. Petersburg?
Honest answer: it depends on the part. Here’s the general range for common AC repairs in the St. Petersburg market — your actual quote depends on your system, the specific part, and whether the repair uncovers related issues. We give you a written flat-rate quote before we start, so there are no surprises.
- Service call / diagnostic: flat fee, waived if you proceed with the repair.
- Capacitor replacement: one of the most common and affordable AC repairs.
- Contactor replacement: another common failure, similar price range to a capacitor.
- Refrigerant recharge: depends on the amount and type (R-410A vs R-454B). Important: if the system is low, there’s a leak — refilling without finding the leak is a short-term fix.
- Blower motor replacement: mid-range repair, significant labor involved.
- Evaporator coil or condenser coil replacement: larger repair, usually the decision point between repair and replacement.
- Compressor replacement: the most expensive common AC repair. At this price point, most homeowners choose to replace the whole system — and we’ll give you an honest side-by-side quote if that’s the situation.
Check our current specials — we rotate seasonal offers on AC service and tune-ups. For larger repairs and replacements, we offer financing on qualifying jobs.
Should You Repair or Replace?
It’s the single biggest question we get. A good HVAC tech should tell you honestly — not just sell you the bigger ticket. Here’s the general rule of thumb we use when advising St. Petersburg homeowners:
- Under 10 years old, minor repair: almost always repair.
- 10–15 years old, moderate repair: depends on the repair cost vs. system efficiency. Older single-stage units are expensive to run compared to modern two-stage and variable-speed systems — sometimes the repair is cheaper, but replacement pays back quickly in energy savings.
- 15+ years old, major repair (compressor, coil): usually replace. At that age, even a big repair just buys you time before the next big repair.
- System uses R-22 refrigerant: R-22 is phased out. Refills are expensive and getting rarer. Most R-22 systems are candidates for replacement.
When the right call is replacement, we’ll give you a written quote on a new system — and we’ll show you the repair quote side-by-side so you can make the call with real numbers. See our AC installation page for details on replacement systems.

AC Repair FAQs
How quickly can you get to my house for an AC repair?
For emergency calls in St. Petersburg, often within the hour. Standard calls are usually booked same-day or next-day, depending on what time you call. Our dispatcher will give you a real service window — not a vague “sometime today.”
Do you charge a service fee just to come out?
Yes — a flat diagnostic fee applies to repair calls so our licensed tech can properly inspect and diagnose the system. If you move forward with the repair, that fee is typically applied toward the total. Full-system replacement estimates are free.
Why is my AC running but not cooling the house?
The most common causes are low refrigerant (meaning there’s a leak somewhere in the system), a dirty evaporator coil, a failing compressor, or a frozen indoor coil caused by restricted airflow. A tech needs to diagnose by reading pressures and temperatures — it’s not safely guessable from symptoms alone.
How long should an AC repair take?
Most common repairs — capacitors, contactors, drain lines — take under an hour once the tech is on-site. Bigger repairs like blower motors or coils can take 2–4 hours. Compressor replacements are an all-day job.
Will you give me a price before starting the repair?
Always. Every Flow Pros AC repair is quoted with a flat-rate price in writing before any work begins. No hourly surprises, no mid-job “it’s actually going to cost more.”
Do you work on all AC brands?
Yes — Trane, Carrier, Lennox, Rheem, Goodman, American Standard, Bryant, York, Payne, Amana, and more. Our techs are trained across manufacturers.

We’re a family-owned St. Pete company with 1,342+ five-star reviews — most of them on plumbing work where the same upsell temptation exists. Reputation is the whole game in a local service business. We’d rather fix your capacitor and earn your next 10 years of calls than pressure you into a replacement you don’t need.
Is Flow Pros licensed for HVAC work?
Yes. Flow Pros carries a Florida HVAC contractor’s license (CAC#######) alongside our plumbing license (CFC1433820). Both license numbers appear on every invoice and at the bottom of this page.
