    Fast response • No overtime fees • Same-day leak detection & recharge. EPA-certified technicians respond within 90 minutes to stop refrigerant loss and restore cooling.

    Signs You Have a Refrigerant Leak

    AC blowing warm or "lukewarm" air

    Low refrigerant equals no cooling cycle. When refrigerant levels drop, your AC cannot absorb heat from inside your home, resulting in warm or lukewarm air coming from vents. This is the most common sign of a refrigerant leak.

    Ice on refrigerant lines or evaporator coil

    This is the #1 sign of a major leak. When refrigerant levels are critically low, the evaporator coil freezes solid, and ice forms on refrigerant lines. You may see ice buildup on the outdoor unit or hear water dripping from the air handler as the ice melts.

    Hissing, bubbling, or high-pitched noise

    Refrigerant literally escaping under pressure creates audible sounds. If you hear hissing, bubbling, or high-pitched noises near your AC system, refrigerant is actively leaking. This requires immediate emergency service to prevent further damage.

    Outdoor unit running but indoor air still warm

    This is a classic low-refrigerant symptom. The compressor and outdoor unit may be running, but without sufficient refrigerant, the system cannot transfer heat effectively. The AC runs continuously but cannot cool your home.

    AC running nonstop

    The system tries to cool but can't reach temperature. When refrigerant is low, your AC runs continuously trying to achieve the set temperature, but it never reaches it. This causes excessive wear and dramatically increases energy bills.

    Higher humidity inside the home

    Refrigerant is responsible for moisture removal. When refrigerant levels are low, the AC cannot effectively dehumidify the air. You'll notice sticky, humid conditions even when the AC is running, which is a clear sign of refrigerant problems.

    Sudden spike in electric bills

    System is overworking due to refrigerant loss. When refrigerant is low, the compressor works harder and longer to try to cool your home, consuming significantly more electricity. A sudden increase in energy bills often indicates a refrigerant leak.

    Water leaking from the air handler

    Melting ice dripping off frozen coil. When the evaporator coil freezes due to low refrigerant, the ice eventually melts and causes water to leak from the air handler. This water damage can cause additional problems if not addressed immediately.

    A Refrigerant Leak Is an Emergency That Can Destroy Your AC System

    A refrigerant leak isn't just a cooling issue—it's an emergency that can damage your AC system, raise indoor humidity, cause compressor failure, and make your home dangerously hot. During a Nassau County heat wave, losing refrigerant means losing cooling immediately. Our licensed technicians respond within 90 minutes to diagnose the leak, stop the refrigerant loss, and restore your AC's cooling performance—day or night, weekends, holidays, whenever it fails. Refrigerant does NOT "run out." If it's low—you have a leak. Period. Most AC failures are inconvenient, but a refrigerant leak can destroy your compressor ($2,000–$4,000 repair), cause coils to freeze solid, lead to catastrophic system failure, drive indoor humidity dangerously high, cause the system to overheat, make electrical components burn out, flood the surrounding area with ice melt, and leave your home above 85°F within hours. If your AC lost refrigerant, turn it off immediately and call for emergency service.

    Our Simple Process

    From call to comfort in 6 easy steps

    1

    Immediate System Safety Check

    We shut off unsafe components to prevent compressor burnout, coil damage, electrical overload, and fire hazards. This step alone can save you thousands in damage. We ensure your system is safe before proceeding with leak detection.

    2

    Emergency Leak Detection

    We use UV leak detection dye, electronic refrigerant sniffers, high-pressure nitrogen test, coil inspection, line-set examination, Schrader valve testing, and bubble test for micro leaks. We find leaks fast and accurately, identifying the exact location and severity.

    3

    Stop the Leak

    Depending on the cause, we repair line-set damage, tighten connections, replace Schrader valves, seal micro-leaks, repair solder joints, patch copper tubing, or replace faulty components. If the leak is in the evaporator coil, we can perform temporary recharge if safe, patch minor coil leaks, or replace the coil if heavily compromised. Your system is stabilized immediately.

    4

    Refrigerant Recharge

    After fixing the leak, we pull a deep vacuum to remove moisture and contaminants, precisely weigh in factory refrigerant charge, balance pressures, and verify superheat/subcooling. We use ONLY EPA-certified refrigerants—NO substitutes. This ensures proper system operation and compliance with regulations.

    5

    Full System Test

    We ensure no further leaks, proper cooling temperature, correct airflow, compressor operating safely, indoor humidity returning to normal, system reaches set temperature, and pressure levels are stable. You get cold air again—quickly and safely.

    6

    Repair Options & Prevention

    We explain what caused the leak, what was repaired, show photos of the damaged part, and provide long-term prevention steps. We keep everything transparent so you understand what happened and how to prevent it from happening again.

    Frequently Asked Questions

    Get answers to common questions about our services

    Can I add refrigerant without fixing the leak?

    No. It's illegal and will cause the system to fail again. Federal law requires EPA certification to handle refrigerant, and adding refrigerant without fixing the leak is a violation. The refrigerant will leak out again, wasting money and causing further damage to your system.

    How long does emergency refrigerant repair take?

    Most repairs take 1–2 hours. Major leaks may require same-day or next-morning completion. We work quickly to restore your cooling and protect your system from further damage.

    How do I know if my coil is leaking?

    We use professional leak detection tools including UV dye, electronic sniffers, and pressure testing to confirm coil leaks in minutes. Signs include ice buildup, warm air, and water leaks from the air handler.

    Will my system need a replacement?

    Only if the leak is severe or the system is very old. We always repair first if possible. Most leaks can be repaired, saving you thousands compared to full system replacement.

    What causes refrigerant leaks?

    Common causes include corroded copper tubing (especially in Long Island's salt-influenced air), weak or cracked solder joints, pinhole leaks in evaporator coils (common in systems 8+ years old), damaged Schrader valves, rubbing/abrasion leaks, factory defects, or improper past repairs.

    What should I do if I suspect a refrigerant leak?

    Turn off your AC immediately—running it low on refrigerant can destroy the compressor. Don't attempt DIY refrigerant fixes (you need EPA certification by law). Avoid running fans if the coil is frozen. Take a photo of the issue to help diagnosis. Call us immediately, especially if you hear hissing, see ice, air is warm, outdoor unit is hot, or indoor humidity is extreme.

    Why are refrigerant leaks an emergency?

    A refrigerant leak can destroy your compressor ($2,000–$4,000 repair), cause coils to freeze solid, lead to catastrophic system failure, drive indoor humidity dangerously high, cause the system to overheat, make electrical components burn out, and leave your home above 85°F within hours. A $250 leak repair today can prevent a $4,000 replacement next week.

    Do you charge overtime for emergency refrigerant leak repair?

    Never. We charge the same fair rate day or night, weekends and holidays. Refrigerant leaks are emergencies that don't wait for convenient times—we don't charge extra for responding when you need us most.
