Understanding Common Air Conditioning Problems

Compressor failures represent another significant concern, often resulting from electrical issues, refrigerant problems, or simple wear and tear over years of operation. When a compressor fails, the entire cooling cycle breaks down, leaving homeowners without relief during sweltering summer days. We also frequently diagnose frozen evaporator coils, typically caused by restricted airflow from dirty filters or blocked return vents. These ice formations prevent proper heat exchange and can damage other components if left unaddressed. Opening up the shop over 40 years ago, S&S Mechanical started as a small operation and quickly grew through referrals from happy customers eager to tell their friends and family about their experiences with our thorough diagnostic approach.

Our Comprehensive Repair Process

When you contact us for air conditioning repair, our Trust Certified technicians follow a systematic approach to ensure accurate diagnosis and lasting solutions. Upon arrival, we begin with a complete system inspection, checking electrical connections, measuring refrigerant levels, testing capacitor functionality, and evaluating thermostat calibration. This thorough examination typically takes 45 to 60 minutes and helps us identify not only the immediate problem but also potential issues that could develop into major failures.

Our diagnostic process includes using advanced tools such as digital manifold gauges, which provide precise pressure readings accurate to within 0.5 PSI, and thermal imaging cameras that detect temperature variations invisible to the naked eye. These technologies enable us to pinpoint refrigerant leaks, identify failing components before complete breakdown, and assess overall system efficiency. After diagnosis, we provide detailed explanations of our findings, discussing repair options and helping you make informed decisions about your system’s future.

Emergency Response and Rapid Solutions

Air conditioning failures rarely happen at convenient times, which is why we maintain a fleet of fully stocked service vehicles ready for immediate deployment throughout the greater St. George area. Our normal business hours are Monday through Friday 7am – 6pm, but we are also available on-call for emergencies. We can usually dispatch an HVAC technician to be at your home within 2 hours of the initial phone call if it is an emergency, ensuring minimal disruption to your comfort and daily routine.

Our service vehicles carry over 200 different parts and components, allowing us to complete most repairs during the initial visit. This inventory includes compressor capacitors, fan motors, control boards, refrigerant, thermostats, and various electrical components commonly needed for AC repairs. By maintaining this extensive parts inventory, we eliminate the frustration of multiple service appointments and get your system operational quickly.

Technical Expertise and Industry Standards

The air conditioning industry has evolved significantly over the past decade, with new refrigerants, improved efficiency standards, and advanced control systems becoming standard. Our technicians stay current with these developments through continuous training and certification programs. We only hire technicians with at least 4 years of experience or more, ensuring every team member possesses the knowledge to work on systems ranging from older R-22 units to the latest R-410A and R-32 equipment.

Modern air conditioning repairs often involve sophisticated electronics and variable-speed components that require specialized knowledge. Our team understands the intricate relationships between inverter-driven compressors, communicating thermostats, and zoning systems. We diagnose and repair:

• Variable refrigerant flow systems that adjust cooling capacity based on demand
• Multi-stage cooling systems providing enhanced humidity control and efficiency
• Smart thermostat integration issues affecting remote access and scheduling
• Ductless mini-split systems requiring specialized refrigerant handling procedures
• Heat pump reversing valve problems impacting both cooling and heating operations

Each repair we perform meets or exceeds manufacturer specifications and industry best practices, ensuring your system operates safely and efficiently. Our commitment to quality extends beyond the repair itself, as we test system performance thoroughly before considering any job complete, verifying proper temperature differentials, airflow rates, and electrical consumption to confirm optimal operation.
