A typical AC tune-up from DRG Mechanical includes a full system assessment focused on performance, safety, and indoor air quality. Most visits center on verifying the cooling system is operating as designed, properly sized for the home, and moving the right amount of air. Our technicians perform these checks across the Sioux Falls area and document results so decisions are clear. Members of our Comfort Club receive two seasonal maintenance visits, priority scheduling, discounted diagnostics, 15% off repairs, and 10% off indoor air quality products.
What we typically check and document:
- Full system inspection and diagnostic evaluation
- Airflow and duct performance testing, including static pressure measurement
- Filter review with correct cabinet sizing and clear labeling
- Load calculation and right-sizing review when comfort or efficiency concerns arise
- Indoor air quality recommendations (humidifiers, UV, or purifiers) when appropriate
Schedule maintenance before peak cooling season to catch airflow or sizing issues early.
