Mini Split Repair
West Palm Beach FL
Your AC stopped working. It's 91°F outside and the house is heating up fast.
Most repairs run $85 to $700. Drain clogs and capacitor failures are the top two causes in WPB — both fixed same day. We give you the exact price before we touch anything.
What's Wrong With Your Mini Split?
If your unit stopped working, it's almost always one of six things. Here's what each one sounds like and what it costs to fix in West Palm Beach.
Not Blowing Cold Air
Your unit runs, the fan moves, but the air feels warm. That's usually low refrigerant from a leak or a coil coated in salt deposits from the Intracoastal air — common in El Cid, SoSo, and Flamingo Park. Refrigerant recharge runs $200 to $600.
See all causes →Water Dripping From Indoor Unit
Your drain line is clogged. Stop the unit, put towels down, and call us. WPB's year-round humidity lets algae grow inside the condensate drain line in 3 to 6 months. When it blocks up, water backs up onto your floor or ceiling. This is our most common call in Palm Beach County. Fix runs $85 to $180.
See all causes →Unit Won't Turn On
Check the breaker first. Reset it once. If it trips again immediately, stop — that means a deeper problem. West Palm Beach gets 60+ thunderstorm days a year. FPL surges during afternoon storms kill control boards regularly. If the unit went dead during a storm, it's likely the inverter board ($400 to $700).
What to check →Blinking Light or Error Code
The unit is telling you what's wrong. Count the blinks or note the display code. The most common codes in WPB involve drain faults (algae clogs) and communication errors between indoor and outdoor units — usually from surge damage. We read all Mitsubishi, Daikin, Fujitsu, LG, and MRCOOL codes on arrival.
Full error code guide →Grinding, Buzzing, or Squealing
Each sound points to something specific. Grinding means the blower motor bearings are worn — WPB humidity accelerates that wear. Buzzing often means the capacitor. Squealing usually means a fan motor is failing. None of these fix themselves, and all three get more expensive if ignored.
Get help now →Ice on the Indoor Unit
The evaporator coil froze. Turn the unit off — don't chip or melt the ice. Let it thaw fully, then call us. Frozen coils happen when refrigerant is low or when restricted airflow forces the coil below 32°F. Refrigerant work requires EPA Section 608 certification, which is a federal requirement, not just a suggestion.
Why coils freeze →Why Mini Splits Break Faster in West Palm Beach
This is not a general HVAC site. We work across WPB every day. The problems here are different from Orlando or Jacksonville, and the solutions have to match.
Salt Air From the Intracoastal Waterway
Salt-laden air from Lake Worth Lagoon and the Atlantic moves through El Cid, Flamingo Park, SoSo, and Northwood every day. It corrodes aluminum coils and copper refrigerant line fittings 2 to 3 times faster than inland properties. A unit that lasts 18 years in Orlando might need its coils replaced after 10 years on Flagler Drive. The Royal Park, Flagler Memorial, and Southern Boulevard bridges connect WPB to the Town of Palm Beach — and that corridor carries the saltiest air in the county.
Historic Homes With No Original Ductwork
The 1920s and 1930s bungalows and Spanish Revival homes near Howard Park, along South Dixie Highway's Antique Row, and throughout the El Cid historic district were built before forced-air systems existed. No ducts were ever installed. Mini splits aren't a convenience in these homes — they're the only way to cool the rooms. When one fails, there's no backup. That's why the call comes within an hour of the unit stopping.
10 or 11 Months of Annual Runtime
In most of the country, AC systems get a few months off every winter. In West Palm Beach, they run from March through November — and often through December and February. That's 10 to 11 months of continuous operation. Capacitors, fan motor bearings, and refrigerant seals wear out faster because they log more hours per year than the same part would in a northern city. Florida heat accelerates capacitor failure beyond what manufacturer estimates assume (source: HVAC Pro Sales 2026 repair guide).
Afternoon Thunderstorms Burn Out Control Boards
Between June and September, West Palm Beach averages multiple lightning events per week. FPL power surges during these storms damage mini split control boards and inverter circuits regularly. Homes in Grandview Heights, the Palm Beach Lakes corridor near the Kravis Center, and anywhere with older electrical panels are most at risk. The repair we see most after a storm: dead control board, unit won't power on at all, $400 to $700 to replace.
Humidity Clogs Drain Lines Every 3 to 6 Months
WPB's year-round heat and humidity create the perfect conditions for algae and mold to grow inside the condensate drain line — and they grow fast. In a climate with a real winter, drain lines dry out and algae colonies die off. Here, the line stays warm and wet all year. Homeowners near the waterfront on the Intracoastal side of downtown, and in high-rise condos along Flagler Drive, need this service every 3 to 4 months rather than the once-a-year recommendation that applies in drier climates.
What Mini Split Repair Costs in West Palm Beach — 2026
According to Manta's 2026 cost data for Palm Beach County, homeowners pay between $89 and $761 on average for AC repair. Here's how that breaks down for ductless systems.
| Repair Type | WPB Cost Range | Time | WPB-Specific Note |
|---|---|---|---|
| Diagnostic / service call | $75–$150 | 30 min | Credited toward repair when you proceed |
| Drain line cleaning | $85–$180 | 45–60 min | Most common WPB call — algae from humidity |
| Capacitor replacement | $150–$350 | 30–60 min | Florida heat kills these faster than northern climates |
| Coil cleaning (evaporator) | $150–$300 | 60–90 min | Salt deposits from coastal air — Intracoastal-side homes most affected |
| Refrigerant recharge (R-410A) | $200–$600 | 2–3 hrs | Includes leak detection. Recharging without fixing the leak wastes money. |
| Blower motor replacement | $300–$600 | 2–3 hrs | Humidity wears bearings down — grinding noise is the warning sign |
| Control board / inverter | $400–$700 | 2–4 hrs | Lightning surge damage — very common in WPB summers |
| Compressor replacement | $800–$1,800 | 4–6 hrs | At this cost, get a replacement quote too — especially if the unit is 10+ years old |

One rule every WPB homeowner should know: if a repair costs more than half the price of a new system, get a replacement quote alongside the repair estimate. We'll give you both numbers honestly. A repair that makes sense on a 5-year-old unit often doesn't make sense on a 12-year-old coastal unit.
When Mini Splits Fail Most in West Palm Beach
WPB runs AC 10 to 11 months a year. Knowing when failures peak helps you act before you're stuck waiting in the heat.
What You See — What We Fix — What It Costs
No fuzzy descriptions. Every observable symptom, its WPB-specific cause, and the exact repair with 2026 price range.
| What you see or hear | WPB cause + fix | Cost range | Time |
|---|---|---|---|
| Water dripping from indoor unitAct today Most common WPB call — drain overflows within 24 hrs |
Algae clog in condensate drain line. Wet-dry vacuum flush + enzyme treatment + algae inhibitor tab. Float switch test to confirm drainage. | $85–$180 | 45–60 min |
| Running but blowing warm air Capacitor, refrigerant leak, or coil deposits from salt air |
Capacitor test first ($150–$350). If passes, refrigerant pressure check for Intracoastal-side salt corrosion leaks. Coil cleaning if coated in deposits. | $150–$600 | 1–3 hrs |
| Won't turn on at allAct today Tripped breaker, failed capacitor, or storm surge board damage |
Check breaker first — reset once only. If trips again, stop. Control board inspection for lightning surge damage (most common cause after WPB storms). | $75–$700 | 30 min–4 hrs |
| Blinking light or error code Drain fault (most common) or refrigerant/communication fault |
Code read on all brands at arrival — Mitsubishi, Daikin, Fujitsu, LG, MRCOOL. Drain fault codes fixed same day. Refrigerant codes need EPA 608 tech. | $85–$600 | 45 min–3 hrs |
| Grinding noise from indoor unit Blower motor bearings — WPB humidity accelerates wear |
Blower motor bearing inspection. WPB humidity wears bearings faster than drier climates. Early repair ($300–$450) prevents full motor failure ($600). | $300–$600 | 2–3 hrs |
| Buzzing from outdoor unit Capacitor failing — Florida heat kills capacitors faster |
Run capacitor test and replacement. Florida's heat degrades capacitors faster than any other US climate. 30 to 60-minute fix when caught early. | $150–$350 | 30–60 min |
| Ice forming on indoor unitTurn off now Low refrigerant or restricted airflow — turn off, let thaw |
Turn unit off immediately — do not chip ice. Let thaw 2 to 4 hours. Clean filter first. If freezes again: refrigerant leak. EPA 608 required for recharge. | $200–$600 | 2–4 hrs |
| FPL bill spiked without explanation Dirty evaporator coil from salt deposits near Intracoastal |
Evaporator coil cleaning — salt deposits from Intracoastal air coat the fins and force the unit to run longer to reach set temperature. | $150–$300 | 60–90 min |
| Musty smell from ventsNon-urgent Mold in drain line or evaporator coil — common in WPB |
Drain line flush + coil cleaning + antimicrobial treatment. WPB's humidity lets mold grow in drain lines and on coil surfaces faster than drier climates. | $150–$300 | 60–90 min |
| Unit shuts off repeatedly Short cycling — often drain float switch or low refrigerant |
Float switch check first (drain clog). If clear: refrigerant pressure test. Short cycling strains the compressor — more expensive if ignored. | $85–$600 | 45 min–2 hrs |

Common Questions From WPB Homeowners
Straight answers — no hedging, no upselling over the phone.
Most repairs run $85 to $700. Drain line cleaning costs $85 to $180. Capacitor replacement is $150 to $350. Refrigerant recharges run $200 to $600. Control board replacement is $400 to $700. Manta's 2026 data for Palm Beach County puts the average AC repair between $89 and $761. You get the exact price before we start — no surprises after the fact.
The most common causes here: a clogged condensate drain line triggering the safety float shutoff (algae from WPB humidity clogs these every 3 to 6 months), low refrigerant from a salt-air corrosion leak — especially on homes near the Intracoastal in El Cid and SoSo — a coil coated in coastal deposits blocking heat transfer, or a failed run capacitor. A technician can diagnose the exact cause in under 30 minutes.
No. Same price on Sunday as on Monday. WPB's afternoon thunderstorm season doesn't follow business hours, and neither does our dispatch. Saturday evening, Sunday morning — same rate applies.
Every 6 months minimum. Homes in El Cid, SoSo, Flamingo Park, and anywhere near the Intracoastal Waterway need it every 3 to 4 months. WPB's year-round humidity lets algae build up in the condensate drain line far faster than in drier climates. When the line blocks, water can damage floors or ceilings within 24 to 48 hours — WPB's ambient humidity turns standing water into mold quickly.
Repair it if the cost is under half the price of a new system and the unit is under 10 years old. Replace it if it uses R-22 refrigerant (no longer manufactured, now $50 to $150 per pound with no domestic supply), if it's over 10 years old and near the coast where salt air shortens the expected lifespan, or if the compressor has failed on an older unit. We'll give you both numbers and let you decide — no pressure in either direction.
