Understanding Your AC System: How It Works and What Can Go Wrong

Your air conditioning system is a complex network of components designed to provide cooling comfort. It operates by extracting heat from indoor air and transferring it outside, using refrigerant to facilitate the cooling process. Several essential parts work together to maintain efficiency, including:

• Compressor: The compressor is the core of your AC system, circulating refrigerant to transfer heat and enable cooling. It plays a crucial role in maintaining efficient temperature control and system performance.
• Evaporator Coil: The evaporator coil absorbs heat from indoor air, allowing the refrigerant to cool the space effectively. Proper airflow and refrigerant levels ensure efficient cooling and prevent coil freezing.
• Condenser Coil: Located outdoors, the condenser coil releases absorbed heat, allowing the refrigerant to cool and cycle back. Clean coils improve efficiency, ensuring your AC operates smoothly without excessive energy consumption.
• Air Ducts: Ductwork distributes conditioned air throughout your home or business, maintaining consistent temperatures. Leaky or unclean ducts can reduce efficiency, increase energy costs, and impact indoor air quality.
• Thermostat: The thermostat regulates indoor temperatures by signaling the HVAC system to turn on or off. A properly functioning thermostat ensures energy efficiency, comfort, and accurate temperature control.

However, even the most reliable systems experience issues over time. Common AC problems include:

• Refrigerant Leaks: Low refrigerant levels prevent your AC from effectively cooling your home. Leaks not only reduce efficiency but can also cause the compressor to overheat and fail. Our technicians locate and repair leaks, recharge refrigerant to optimal levels, and ensure your system operates efficiently without unnecessary strain.
• Frozen Evaporator Coils: Restricted airflow, low refrigerant levels, or dirty coils can cause the evaporator coil to freeze, blocking proper cooling. A frozen coil reduces efficiency and can lead to system failure. We diagnose and fix airflow or refrigerant issues to restore normal operation and prevent future freezing problems.
• Faulty Compressors: The compressor circulates refrigerant to remove heat from your home. If it fails due to overheating, electrical issues, or mechanical wear, your AC won’t cool properly. Our expert repairs address the underlying cause, restoring full system functionality and preventing costly replacements when possible.
• Thermostat Malfunctions: A malfunctioning thermostat can cause incorrect temperature readings, leading to short cycling, inconsistent cooling, or excessive energy use. We troubleshoot calibration errors, wiring problems, or outdated models, ensuring your thermostat accurately controls your HVAC system for optimal performance and comfort.
• Dirty or Clogged Air Filters: A clogged air filter restricts airflow, forcing your system to work harder and reducing efficiency. This can lead to overheating, poor indoor air quality, and higher energy bills. Regular filter maintenance improves airflow, extends system lifespan, and ensures cleaner, healthier air circulation.

Understanding how your AC system works and recognizing early warning signs can help prevent costly repairs. If you notice any of these issues, call Stewart Heating Plumbing Air Conditioning for expert AC services.

From Leaky Ducts to Broken Compressors: We Handle Any AC Repair

At Stewart Heating Plumbing Air Conditioning, we’ve seen it all. No matter the problem, our team of expert technicians can diagnose and fix any AC issue efficiently. Some of the most common repairs we handle include:

• Leaky or Poorly Sealed Ducts: Air leaks in ductwork can significantly reduce HVAC efficiency, forcing your system to work harder and increasing energy costs. Poorly sealed ducts lead to uneven cooling, reduced airflow, and increased strain on your unit. Sealing or repairing ducts helps improve comfort, efficiency, and indoor air quality.
• Electrical Issues: Faulty wiring, loose connections, or capacitor failures can disrupt your air conditioner’s performance. Electrical problems can cause the system to short-cycle, fail to start, or shut down unexpectedly. Our technicians diagnose and repair electrical faults to restore proper functionality and prevent potential safety hazards.
• Thermostat Calibration and Repair: A malfunctioning thermostat can lead to inconsistent temperatures, frequent cycling, or system inefficiency. If your thermostat isn’t communicating properly with your AC, we recalibrate or replace it to ensure accurate temperature control, improved comfort, and optimal energy efficiency.
• Compressor Failures: The compressor is the heart of your AC system, responsible for circulating refrigerant. Overheating, electrical malfunctions, or refrigerant imbalances can lead to compressor failure. Our expert repairs address the root cause of the issue, restoring proper cooling and preventing costly system breakdowns.
• Drainage Problems: Clogged or improperly installed condensate drains can cause water to back up, leading to leaks, humidity imbalances, and potential water damage. We clear blockages, check for proper drainage, and prevent moisture-related issues that could affect indoor air quality and system performance.

Our team is equipped with cutting-edge tools and extensive industry knowledge to ensure that your air conditioning system is restored to peak performance. We also offer proactive maintenance services to help prevent future breakdowns and extend your AC system’s lifespan.
