Diagnostic and Repair Scope

Accurate diagnostics are the cornerstone of effective HVAC service. Our technicians focus on identifying the root cause of system failures rather than just addressing symptoms. Modern systems are intricate networks of electrical, mechanical, and airflow components, what appears as a minor symptom may indicate a deeper issue.

Key Diagnostic Services

• Electrical System Analysis: Testing capacitors, contactors, and relays to ensure proper power distribution.
• Refrigerant Level Check: Measuring superheat and subcooling to detect leaks or undercharged systems.
• Airflow Evaluation: Inspecting blower wheels, filters, and ductwork for optimal airflow.
• Condensate Drain Inspection: Clearing lines to prevent water backups and potential damage.
• Thermostat Calibration: Verifying accurate temperature readings and communication with control boards.

All diagnostic visits include a thorough safety inspection: gas furnaces are checked for heat exchanger cracks, and AC units are inspected for electrical issues. Clients receive a detailed report with required parts, labor, and an upfront quote before any work begins.

System Replacement and Installation Process

Sometimes repair is no longer viable, or homeowners prefer upgrading to improve efficiency. Proper installation is critical, accounting for up to 70% of a system’s efficiency and longevity. Oversized or undersized units cause short-cycling, humidity problems, and premature failure.

Our Installation Approach

• Manual J Load Calculation: Determines correct system sizing based on home square footage, insulation, windows, and local climate.
• Ductwork Assessment: Ensures existing ducts can support modern, high-efficiency equipment.
• Site Preparation: Protect floors and safely disconnect old equipment, recovering refrigerants per EPA standards.
• Unit Positioning and Connection: Indoor and outdoor units leveled, outdoor units cleared for airflow.
• Refrigeration Line Brazing: Nitrogen brazing prevents oxidation, ensuring compressor longevity.
• Triple Evacuation: Removes moisture and non-condensables before releasing factory refrigerant charge.
• System Commissioning: Testing static pressure, temperature splits, and gas pressures to meet manufacturer specifications.

Deciding Between Repair and Full Replacement

Choosing repair versus replacement requires financial and operational analysis. The "5,000 Rule" is a helpful guideline: multiply the system’s age by repair cost, if over $5,000, replacement is usually more practical.

Factors to Consider

• Energy Efficiency: Older systems (10–12+ years) often operate at lower SEER ratings, increasing energy costs. Modern units can save significantly.
• Refrigerant Type: R-22 (Freon) systems are expensive to repair due to phase-out regulations.
• Frequency of Breakdowns: More than two repairs in two years indicates the system is nearing the end of its useful life.
• Comfort Consistency: Uneven temperatures or humidity issues may require variable-speed equipment.
• Warranty Status: Expired warranties increase the financial risk of major repairs.

Airtech Mechanical Service Inc. provides honest assessments, outlining both repair and replacement options to help you make the most cost-effective and long-term decision.

Navigating Local Climate and Regulatory Requirements

North Carolina’s climate presents unique HVAC challenges, including hot, humid summers and occasional cold snaps. Systems must operate efficiently under these conditions, especially for dehumidification and comfort. Severe weather threats require secure outdoor unit installations, often with hurricane-rated pads and tie-downs.

Critical Local Considerations

• Permitting and Codes: All significant work complies with local regulations for safety and performance.
• Seasonal Maintenance: Pre-season checks prevent emergency calls during extreme weather.
• Utility Rebates: High-efficiency upgrades may qualify for local rebate programs.
