AC Symptoms We Fix Every Day
Our technicians have diagnosed and repaired tens of thousands of residential AC systems across South Florida. Here are the issues we see most often:
1. AC Blowing Warm Air or Weak Cooling
Usually caused by low refrigerant (R-410A or legacy R-22), a clogged air filter, a dirty evaporator or condenser coil, or a failing compressor. A properly charged system should drop the return-air temperature by about 18–22°F at the supply register.
2. AC Not Turning On At All
Tripped breaker, blown capacitor, bad contactor, faulty thermostat, or a failed condensate safety float switch are the usual culprits. We carry capacitors, contactors, and fuses on every truck, so most “AC won’t start” calls are resolved on the first visit.
3. Frozen Evaporator Coil
Ice on the indoor coil is almost always caused by low refrigerant, restricted airflow from a dirty filter, or a failing blower motor. We thaw, diagnose the root cause, and fix it — not just restart it.
4. Water Leaking from the Air Handler
In South Florida’s humidity, condensate lines clog fast with algae. Left unaddressed, the safety switch shuts down your system — or worse, water damages your ceiling. We flush, treat, and replace lines as needed.
5. Strange Noises (Rattling, Buzzing, Grinding)
Loose fan blades, a failing blower motor, a bad compressor bearing, or debris in the condenser. Ignoring noises turns a $200 repair into a $3,000 compressor replacement.
6. Short Cycling
The unit turns on and off every few minutes. Causes: oversized system, bad thermostat, dirty coils, or low refrigerant. It wastes electricity and shortens compressor life.
7. High Electric Bills
FPL bills spiking? Your AC is usually 50–60% of summer electricity usage. A tune-up or repair often pays for itself in a single billing cycle.

When to Repair vs. Replace
A good rule of thumb in Florida:
- System under 10 years old, repair under $1,500 → repair
- System 10–15 years old with a major failure (compressor, coil) → get a replacement quote
- System 15+ years old using R-22 refrigerant → replace (R-22 is phased out and costs hundreds per pound when available)
We give you honest numbers both ways and let you decide. See our AC installation options →

Frequently Asked Questions
How much does AC repair cost in South Florida?
Most common repairs (capacitor, contactor, thermostat, condensate clog) run $150–$450. Refrigerant recharge $300–$700 depending on type and amount. Compressor replacement $1,800–$3,500. We quote flat-rate upfront.
Can you come out today?
Yes. Same-day service is standard and the diagnostic fee stays $49 even on weekends and holidays.
Is my refrigerant R-22 or R-410A?
Systems installed before 2010 are usually R-22 (phased out). 2010 and newer are R-410A. We check the data plate on your outdoor unit during diagnosis.
Why is my AC freezing up?
Low refrigerant, dirty filter, or a failing blower motor are the top three causes. Turn the unit off, let it thaw, and call us before running it again to avoid compressor damage.
Do you warranty your repairs?
Yes. Every repair includes a labor warranty, and parts we supply carry the manufacturer warranty.

Common AC Problems We Fix Across South Florida
South Florida’s salt air, humidity swings, and hurricane-season power surges hit AC systems harder than almost anywhere in the country. These are the seven most common repair calls we answer across Palm Beach, Broward, and Miami-Dade:
- AC not cooling / warm air blowing. Usually a blown capacitor, low refrigerant, or dirty coil. Diagnose in 30 minutes.
- Outside unit running but no cold air inside. Frozen evaporator coil, failed blower motor, or thermostat miscommunication.
- System short-cycling (turns on/off rapidly). Oversized unit, dirty filter, low refrigerant, or failing contactor.
- Ice on the copper line or inside the air handler. Low refrigerant or airflow restriction — shut off AC and call immediately to prevent compressor damage.
- Loud buzzing, grinding, or rattling. Failing motor bearings, loose fan blade, or debris inside unit (common after Florida storms).
- Water leak or ceiling stain below air handler. Clogged condensate line or failed float switch — quick fix when caught early.
- High humidity indoors despite AC running. System is undersized, oversized (short cycling), or the dehumidification setting is off.
