Understanding Common Air Conditioning Problems
When your air conditioning system fails during the peak of summer heat, understanding the root cause becomes essential for effective repair. At Garrett Plumbing and Heating Co., we encounter various AC issues ranging from simple filter replacements to complex compressor failures. Refrigerant leaks represent one of the most frequent problems we diagnose, often manifesting as reduced cooling capacity, higher energy bills, and ice formation on evaporator coils. These leaks typically develop at connection points, service valves, or through microscopic holes in copper tubing caused by formicmic acid corrosion, a chemical reaction between copper, water, and volatile organic compounds in your home’s air.
Electrical component failures account for approximately 35% of air conditioning repair calls we receive throughout Jackson, TN and surrounding areas. Capacitors, which provide the initial surge of electricity to start motors, deteriorate over time due to heat exposure and voltage fluctuations. Contactors, responsible for controlling the flow of electricity to your system’s compressor and condenser fan motor, can wear out from repeated cycling, causing intermittent operation or complete system failure. We maintain extensive diagnostic equipment on our ten fully stocked service trucks to quickly identify these electrical issues and restore your comfort efficiently.
Our Comprehensive Repair Process
When you contact us for air conditioning repair, our mobile dispatched technicians begin with a systematic evaluation of your entire cooling system. We start by checking thermostat settings and calibration, as incorrect settings or faulty thermostats cause nearly 20% of perceived AC problems. Our technicians then inspect air filters, which should be replaced every 30 to 90 days depending on usage and environmental factors. Clogged filters restrict airflow, causing evaporator coils to freeze and potentially damaging the compressor through liquid refrigerant flooding.
Advanced Diagnostic Techniques and Equipment
Modern air conditioning systems incorporate sophisticated electronic controls and variable-speed components that require specialized diagnostic tools. We utilize thermal imaging cameras to identify hot spots in electrical panels, failing components, and inadequate insulation around ductwork. These infrared devices detect temperature variations as small as 0.1 degrees Celsius, revealing problems invisible to conventional inspection methods. Our technicians also employ digital psychrometers to measure temperature and humidity differentials across evaporator coils, ensuring your system achieves the manufacturer’s specified temperature drop of 18 to 20 degrees Fahrenheit.
Because we stock commonly used plumbing, heating and air conditioning parts in our warehouse, we can complete most repairs during the initial service call. Our inventory includes:
- Capacitors and contactors for all major brand systems manufactured within the last 25 years
- ECM and PSC fan motors with various horsepower ratings and mounting configurations
- Expansion valves and filter driers essential for refrigerant system repairs
- Control boards and thermostats compatible with conventional and smart home systems
- Refrigerants including R-410A, R-22, and newer alternatives like R-32
