When your AC blows air but not cold in Pompano Beach, these are the most common causes:
Simple fixes like changing the filter or adjusting thermostat settings work for minor issues. However, refrigerant leaks, frozen coils, and compressor problems need immediate professional service. These issues prevent costly damage. This is critical in Pompano Beach where AC systems work overtime in the heat and humidity.

Your air conditioner should create a 15 to 20 degree temperature drop. This measures the difference between the air entering your system and the air coming out. If you feel air blowing from your vents but it’s not noticeably cooler, something is wrong.
Pompano Beach’s coastal environment puts unique stress on AC systems. The combination of high humidity and salt air makes your unit work harder than systems inland. You’ll notice your AC runs longer cycles here. That’s normal. The system needs more time to remove moisture from the air, not just cool it.
Your AC should keep your home comfortable even on the hottest days. Here’s what normal operation looks like in our climate:
In our years serving Pompano Beach from our 2521 NE 4th Ave location, we’ve seen how coastal conditions affect performance. Salt air corrodes outdoor components faster. High humidity makes systems work overtime. When your AC can’t keep up with these demands, you’ll notice warm air blowing instead of cold.
A clogged air filter is the most common reason your air conditioner stops cooling properly. When the filter gets dirty, it blocks airflow through your system. Your AC needs steady airflow to absorb heat from your home and blow cold air back through your vents.
Florida’s environment makes filters dirty faster than anywhere else in the country. High pollen counts from tropical plants hit Pompano Beach year-round. Humidity causes dust to stick to filter fibers. Salt air carries microscopic particles inland from the ocean. All of this clogs your filter quickly.
Here’s how to check your air filter:
You should change your air filter every 30 to 60 days in Pompano Beach. This is more frequent than recommended in less humid climates. Our Florida climate demands it. In many of the service calls we handle, a dirty filter contributes to the cooling problem. It’s a simple fix that prevents bigger issues.
A clean filter protects your entire system. It prevents frozen coils, reduces energy bills, and extends your AC’s lifespan. Make checking your filter a monthly habit.
Refrigerant is the chemical that makes your AC produce cold air. It circulates through your system, absorbing heat from inside your home and releasing it outside. When refrigerant levels drop too low, your AC can’t transfer enough heat. The result is warm air blowing from your vents.
Your AC was charged with a specific amount of refrigerant when installed. This is a closed system. If levels are low, you have a leak somewhere. Simply adding more refrigerant without fixing the leak wastes your money. The new refrigerant will leak out just like the old refrigerant did.
Watch for these warning signs of a refrigerant leak in Pompano Beach:
Pompano Beach’s coastal location accelerates refrigerant line failures. Salt air causes corrosion on copper refrigerant lines and connections. This is especially true for outdoor components exposed to ocean breeze. We see this frequently in homes within a few miles of the coast.
Refrigerant leaks require professional repair for several reasons. The refrigerant itself can be harmful if handled improperly. Finding the exact location of a leak requires specialized equipment. Repairing the leak and recharging the system requires EPA certification. Only licensed technicians can legally purchase and handle refrigerants.
If you suspect low refrigerant, don’t wait. Call (754) 714-4666 for professional refrigerant leak repair. Our certified technicians will locate the leak, fix it properly, and recharge your system to factory specifications.
A frozen evaporator coil looks exactly like it sounds. You’ll see ice forming on the indoor unit of your AC. Sometimes the entire coil is covered in frost or ice. Other times you’ll notice ice on the refrigerant lines running to your outdoor unit.
When your evaporator coil freezes, it can’t absorb heat from your home. The ice acts as insulation. Your AC will blow air, but it won’t be cold. You might even notice reduced airflow as ice blocks the passages where air should flow through.
Three main problems cause frozen coils. Low airflow from a dirty filter or blocked vents restricts air movement across the coil. Low refrigerant from a leak changes the pressure and temperature in the system. Dirty coils covered in dust and debris can’t transfer heat properly. All three make the coil temperature drop below freezing.
If you discover ice on your AC, take these steps immediately:
Never try to chip or scrape ice off the coils. You’ll damage delicate fins and tubes. Let the ice melt naturally. Running your AC with frozen coils can damage the compressor. This turns a minor problem into an expensive repair.
Florida’s humidity makes frozen coils more common and more dangerous. The moisture in Pompano Beach’s air freezes faster on cold coils. When the ice melts, that water has to drain away. If your drain line is clogged, you’ll have water damage on top of your AC problem.
A frozen coil often signals a bigger issue. If the coil freezes again after thawing, you likely have low refrigerant or airflow problems that need professional diagnosis. Our technicians can identify the root cause and prevent future freezing.
Sometimes your AC blows warm air because of thermostat issues, not mechanical failure. The good news is you can check several things yourself. The bad news is thermostat problems range from simple setting errors to hardware failures that need replacement.
Start with these quick thermostat checks:
Your thermostat measures your home’s temperature and tells your AC when to run. If the thermostat gives wrong information, your AC won’t cool properly. Location matters. A thermostat in direct sunlight or near a heat source will read temperatures higher than your actual home temperature. Your AC will shut off before your home is truly cool.
Older thermostats can develop wiring problems. Loose connections prevent proper communication between the thermostat and your AC. Internal sensors wear out over time. They start giving false temperature readings. These problems require professional replacement.
Smart thermostats offer advantages in humid climates like Pompano Beach. They monitor both temperature and humidity. They learn your cooling patterns and adjust automatically. Many models send alerts when your system needs maintenance. This helps you catch problems before they become expensive repairs.
If you’ve checked all the simple settings and your AC still blows warm air, the thermostat itself may have failed. A preventive maintenance tune-up can catch thermostat issues early and keep your system running smoothly through Florida’s long cooling season.
Your outdoor unit contains the condenser coils. These coils release the heat your AC absorbed from inside your home. When condenser coils get dirty, they can’t release heat efficiently. Your AC works harder but produces less cooling. Eventually, it blows warm air instead of cold.
Pompano Beach’s coastal environment is tough on outdoor AC units. Salt air from the ocean corrodes metal components and coil fins. Tropical vegetation drops leaves, seeds, and pollen onto your unit. Coastal debris like sand and dirt gets pulled into the system by the fan. All of this builds up on your condenser coils and blocks airflow.
You can perform basic outdoor unit maintenance yourself. Turn off power to your AC at the disconnect box near the unit. Use a garden hose to gently spray the coils from inside to outside. This pushes debris out instead of deeper in. Never use a pressure washer. The high pressure bends delicate fins and causes permanent damage.
Check around your outdoor unit regularly. Clear away leaves, grass clippings, and vegetation within two feet of the unit. Make sure the fan blades spin freely and look undamaged. Listen for unusual grinding or squealing sounds that indicate motor problems.
Professional coil cleaning goes deeper than what you can do with a hose. We recommend professional cleaning twice yearly in coastal areas like Pompano Beach. Technicians use specialized cleaners that dissolve salt buildup and stubborn grime. They also inspect the fan motor, capacitor, and electrical connections during service.
We replace salt-damaged outdoor units regularly in homes near the coast. The corrosion happens gradually. You might not notice it until your system stops cooling. Regular HVAC repair in Pompano Beach prevents small corrosion issues from becoming full system failures.
Visit our Pompano Beach location at 2521 NE 4th Ave for outdoor unit inspection. Our technicians can assess your condenser coils and recommend the right maintenance schedule for your coastal location.
The compressor is the heart of your AC system. It pressurizes refrigerant and pumps it through your system. Without a working compressor, your AC cannot cool your home. You’ll hear the system running, but only warm air comes from your vents.
Compressor failure shows clear warning signs. You might hear loud banging, grinding, or clicking sounds from your outdoor unit. Your circuit breaker may trip repeatedly when the AC tries to start. The outdoor unit might hum without the fan spinning. Some compressors fail suddenly while others slowly lose efficiency over months.
When a compressor fails, you face a difficult decision. Compressor replacement typically costs between $1,500 and $3,000. Full system replacement typically ranges from $4,000 to $10,000. These numbers depend on your system size and efficiency rating.
System age matters when deciding between repair and replacement. If your AC is 10 years old or older, replacement often makes more financial sense. You’ll get a new warranty, better efficiency, and years of reliable service. Putting a new compressor in an old system means other worn components will likely fail soon.
At Filterbuy HVAC Solutions, we include a two year Premium Care Plan with every AC replacement. This covers maintenance and gives you priority service. We’ll help you evaluate your specific situation and make the choice that’s right for your home and budget.
A failed compressor usually results from other neglected problems. Low refrigerant forces the compressor to work harder. Dirty coils create excessive heat and pressure. Regular maintenance catches these issues before they destroy your compressor.
Electrical problems can stop your AC from cooling even when nothing seems mechanically wrong. Power issues prevent your system from running properly. Sometimes they mimic refrigerant or mechanical failures. This makes electrical problems tricky to diagnose without professional equipment.
A tripped circuit breaker is the most obvious electrical sign. If your breaker trips once and stays on when you reset it, the problem may have been temporary. If it trips repeatedly, you have an electrical short or system overload. Never keep resetting a tripped breaker. This indicates a serious problem that could cause fire or equipment damage.
Capacitors are electrical components that help your AC start and run. When a capacitor fails, you’ll hear clicking sounds from your outdoor unit. The system tries to start but can’t. Sometimes the fan won’t spin even though you hear humming. Capacitor failure is common in Florida because extreme heat degrades these components faster.
Florida’s temperature swings cause wiring problems over time. Your AC sits in direct sun where outdoor temperatures can become extreme. Wires expand in heat and contract when cooler. After years of this cycle, connections loosen and insulation cracks. Damaged wiring prevents proper power flow to your system.
Electrical repairs require licensed professionals. Working with AC electrical systems is dangerous without proper training and equipment. You could suffer serious injury or death from electrical shock. You could also create fire hazards or damage expensive components.
Power issues sometimes mask other problems. Your AC might be working fine mechanically but receiving inconsistent power. Or mechanical failure might be drawing too much electricity and tripping breakers. Professional diagnosis identifies the real problem so you don’t waste money fixing the wrong thing.
You can safely troubleshoot three things yourself: your air filter, thermostat settings, and circuit breaker. Beyond these basic checks, AC repair requires professional training and equipment. Attempting complex repairs yourself risks injury, equipment damage, and voiding your warranty.
