Answers to Common Questions
View All FAQsWhat Is Included in a Typical AC Tune Up Service?
A typical AC tune-up includes a full system inspection, a deep cleaning of key components, and performance testing to restore efficiency and reliability. Most performance losses come from airflow, drainage, electrical, or refrigerant issues, which thorough maintenance is designed to correct. After service, Fix-it 24/7 provides a detailed inspection report with findings and recommendations. Our technicians serving the Denver metro often see big gains after a true deep clean, not just a quick rinse and filter swap. First-time customers can book a $39 AC Tune-Up & Deep Clean.
Common AC tune-up tasks include:
- Condenser and evaporator coil deep cleaning for better heat transfer
- Drainage system cleaning and testing to prevent leaks and clogs
- Electrical connection tightening, safety checks, and compressor/fan inspection
- Refrigerant level testing and thermostat calibration for correct cycling
Schedule maintenance before peak summer and replace filters as directed to prevent breakdowns. <br/> Updated: 2026-04-03 <br/> Need help in Denver, CO? Call (720) 577-4266 or book online. "Technician Aric did a great job with our annual HVAC inspection and maintenance." — Ann F.
