When your air conditioning system starts leaking, it’s more than just an inconvenience—it’s a warning sign that demands immediate attention. In Houston’s demanding climate, where AC systems work overtime from March through October, even minor leaks can quickly escalate into costly repairs or complete system failures. Whether you’re dealing with mysterious water puddles around your unit, rising energy bills, or declining cooling performance, understanding AC leak detection and repair services can save you thousands of dollars and prevent extensive property damage.

Understanding AC Leaks: Types and Common Causes in Houston

AC leaks fall into two primary categories: refrigerant leaks and water leaks. Each type presents unique challenges and requires different repair approaches, making professional diagnosis essential for effective resolution.

Refrigerant Leaks: The Silent System Killer

Refrigerant leaks represent the most serious threat to your AC system’s performance and longevity. These leaks occur when refrigerant escapes from the closed-loop system through damaged coils, loose connections, or worn components. According to the Environmental Protection Agency (EPA), even a 10% reduction in refrigerant charge can decrease system efficiency by up to 20%.

Common causes of refrigerant leaks in Houston include:

Corrosion from high humidity and salt air exposure
Vibration damage from frequent system cycling
Factory defects in coil manufacturing
Poor installation practices
Normal wear and tear accelerated by extreme heat

Water Leaks: Property Damage Concerns

Water leaks typically originate from the condensate drainage system, which removes moisture extracted from indoor air during the cooling process. Houston’s high humidity levels mean your AC system removes substantial amounts of water daily—sometimes over 20 gallons per day during peak summer conditions.

Primary water leak sources include:

Clogged condensate drains
Damaged drain pans
Frozen evaporator coils
Improper system installation
Blocked air filters restricting airflow

Recognizing AC Leak Warning Signs

Early detection prevents minor issues from becoming major expenses. Houston homeowners should watch for these critical warning signs that indicate potential AC leaks.

Visual and Physical Indicators

The most obvious signs appear as physical evidence around your AC system:

Water pooling: Puddles near indoor or outdoor units
Ice formation: Frozen coils or ice on refrigerant lines
Staining: Water damage on walls, ceilings, or flooring
Corrosion: Rust or deterioration on metal components
Oil residue: Dark spots indicating refrigerant leaks

Performance-Related Symptoms

System performance changes often indicate developing leak problems:

Reduced cooling capacity despite normal operation
Longer cooling cycles to reach desired temperatures
Unusual increases in monthly energy bills
Frequent system cycling on and off
Inconsistent temperatures throughout the home

Professional AC Leak Detection Methods

Professional leak detection employs sophisticated techniques that ensure accurate diagnosis and complete leak identification. At 75 Degree AC, our certified technicians use industry-leading detection methods to locate leaks quickly and precisely.

Electronic Leak Detection

Electronic leak detectors represent the gold standard for refrigerant leak identification. These sensitive instruments can detect refrigerant concentrations as low as 5 parts per million, enabling technicians to locate even microscopic leaks before they cause significant system damage.

Advanced electronic detection offers several advantages:

Pinpoint accuracy in leak location
Detection of multiple refrigerant types
Non-destructive testing methods
Immediate results for faster repairs

Ultraviolet (UV) Dye Detection

UV dye detection involves injecting fluorescent dye into the refrigerant system, then using ultraviolet light to locate leak points. This method proves particularly effective for identifying slow leaks that electronic detectors might miss.

Soap Bubble Testing

For accessible connections and joints, technicians apply soap solutions to suspected leak areas. Bubble formation indicates escaping refrigerant, providing visual confirmation of leak locations.

Comprehensive AC Leak Repair Process

Professional AC leak repair follows a systematic approach that ensures permanent solutions rather than temporary fixes. Our experienced technicians at 75 Degree AC follow industry best practices for lasting repairs.

Initial System Assessment

Every repair begins with comprehensive system evaluation. Technicians examine the entire AC system, checking refrigerant levels, inspecting components, and identifying all potential leak sources.
