Expert AC Refrigerant Leak Detection & Repair on Long Island

AC blows warm or barely cool air, low refrigerant is one of the top causes

Ice forms when refrigerant levels are too low to absorb heat

Leak often creates faint hissing noise, bubbling may indicate leak near evaporator coil or line set

System can't reach thermostat setting because there isn't enough refrigerant to remove heat

Low refrigerant reduces moisture removal from air

When coils freeze and then thaw, excess water can overflow the drain pan

AC runs longer cycles and uses more power

Low refrigerant makes AC nearly useless during heat waves

Can I run my AC if refrigerant is low?

No. Running your AC with low refrigerant strains the compressor and risks permanent damage. The compressor works harder to move less refrigerant, causing overheating and potential failure costing $2,000-$3,500. If you suspect low refrigerant (warm air, ice buildup, weak cooling), turn off your AC and schedule service immediately to prevent costly compressor damage.

How long does leak detection take?

Typically 30-90 minutes depending on the leak's location and severity. Simple leaks at accessible connections can be found quickly with electronic detectors. leaks in coils or buried line sets may require UV dye injection and a return visit, or nitrogen pressure testing for comprehensive diagnosis. We never guess—we find the exact location before repairing.

How much refrigerant does my AC need?

Most residential systems need 4-12 lbs depending on tonnage. A 2-ton system typically holds 4-6 lbs, a 3-ton system holds 6-9 lbs, and a 5-ton system holds 10-12 lbs. However, the exact amount depends on your specific model and line set length. We always charge to manufacturer specifications—never under or overfilling.

Does refrigerant run out like gasoline?

No—this is one of the biggest HVAC myths. Refrigerant is contained in a closed-loop system and should never decrease. If your refrigerant is low, there is 100% a leak somewhere. Adding refrigerant without fixing the leak is like putting air in a tire with a nail in it—temporary and wasteful. We always locate and repair the leak first.

Can leaks be repaired same-day?

Most common leaks (Schrader valves, accessible line set joints, minor coil leaks) can be fixed immediately. Our service vehicles are stocked with brazing equipment, valves, refrigerant, and common repair parts. More complex repairs like evaporator coil replacement or extensive line set replacement may require scheduling a follow-up appointment for proper installation.

Is a refrigerant leak dangerous?

Small leaks aren't generally harmful to humans, but large leaks in enclosed spaces can displace oxygen and cause dizziness or breathing difficulty. R-410A is non-toxic but can cause asphyxiation in high concentrations. Additionally, leaking refrigerant harms the environment. The bigger danger is to your AC system—leaks cause compressor failure, frozen coils, and expensive damage if not addressed quickly.
