Air conditioning contractors are more than just repair experts. They manage the entire lifecycle of your AC system:
1. Installation & Replacement

2. Repair & Troubleshooting
- Diagnose cooling issues (e.g., refrigerant leaks, compressor failure)
- Repair or replace defective parts
- Address air flow and thermostat calibration issues
3. Maintenance & System Tuning
- Clean coils, change filters, and check refrigerant levels
- Perform seasonal tune-ups
- Extend equipment lifespan and improve energy efficiency
4. Project Management
- Pull permits and comply with local building codes
- Supervise crews and subcontractors
- Ensure code-compliant installations and safety standards
5. Consultation & System Design
- Provide custom HVAC designs for remodels or new builds
- Suggest improvements to ductwork or insulation
- Recommend air quality enhancements (like HEPA filters or UV purifiers)
