Package Unit HVAC Systems in Murfreesboro, TN

Once we understand your system’s condition, we perform detailed diagnostics to identify the root cause of any performance issues. For package units, this includes testing both heating and cooling modes, checking refrigerant levels and pressures, measuring electrical amperage on motors and compressors, and verifying that all safety controls are functioning properly.

Package units integrate multiple systems in one cabinet, so problems can affect both heating and cooling. We use professional diagnostic tools to test each component systematically, ensuring we identify all issues — not just the most obvious ones. This thorough approach prevents return visits and ensures your system operates reliably.

• Test heating and cooling operation under load to verify performance
• Check refrigerant pressures and temperatures to identify leaks or charge issues
• Measure electrical amperage on compressor, blower motor, and other components
• Inspect heat exchanger (if gas heating) for cracks or corrosion
• Test all safety controls, limit switches, and protective devices
• Verify proper airflow and check for restrictions in the ductwork
• Document all findings and explain what we discovered in plain English

After diagnostics, we explain exactly what’s wrong with your package unit and what it will take to fix it. We provide clear cost estimates for all necessary repairs and discuss whether repair makes financial sense or if replacement would be a better long-term investment. For older package units, we’re honest about the likelihood of future problems and help you make an informed decision.

Package unit repairs can range from simple filter changes and coil cleaning to major component replacements like compressors or heat exchangers. We prioritize repairs by urgency and cost-effectiveness, so you can address the most critical issues first if budget is a concern. We never pressure you into unnecessary work.

• Explain all identified problems in terms you can understand
• Provide written estimates for each repair with parts and labor broken down
• Discuss repair versus replacement if your system is aging or has multiple issues
• Prioritize repairs by urgency — safety first, then comfort, then efficiency
• Explain warranty coverage on parts and labor for all recommended work
• Answer all your questions about the repair process and timeline
• Give you time to consider your options without pressure to decide immediately

Once you approve the work, our certified technicians perform all repairs using quality parts and proper procedures. Package unit repairs often require working on rooftops or in tight spaces, so safety is our top priority. We use manufacturer-approved parts when possible and ensure all work meets code requirements and manufacturer specifications.

During repair work, we protect your home and property, communicate with you about our progress, and test each repair thoroughly before considering the job complete. Package units integrate heating and cooling, so we verify that both modes operate correctly after any repair work.

• Use proper safety equipment and procedures for rooftop or ground-level work
• Install manufacturer-approved parts with proper torque specifications
• Follow EPA refrigerant handling procedures for any refrigerant work
• Test all electrical connections and verify proper voltage and amperage
• Clean and inspect related components while the unit is open for service
• Verify proper operation in both heating and cooling modes after repairs
• Document all work performed and provide warranty information

After completing repairs, we run a full system test to ensure your package unit is operating correctly in both heating and cooling modes. We verify that temperatures are reaching set points, airflow is adequate throughout your home, and all safety controls are functioning properly. We also check for any issues that might have been masked by the original problem.

Before we leave, we discuss preventative maintenance that will help prevent future problems and extend your package unit’s life. Package units benefit from regular coil cleaning, filter changes, and seasonal tune-ups. Our maintenance plans make it easy to stay on schedule and can prevent many emergency repairs.

• Run complete heating and cooling cycles to verify proper operation
• Check temperature drop across cooling coil and temperature rise across heating elements
• Verify that all zones in your home are receiving adequate airflow
• Test thermostat operation and ensure it’s controlling temperature accurately
• Explain what we repaired and how to prevent similar problems in the future
• Recommend maintenance schedule based on your system’s age and condition
• Provide emergency contact information and explain when to call for service
