Spring Tune-Ups Help Prevent Summer Emergency Service Calls

Over 75 percent of summer emergency service calls in Houston stem from worn electrical components that could have been identified during a routine spring tune-up. High heat degrades capacitor dielectric fluid over time. When a weakened capacitor fails on a 98-degree afternoon, the compressor motor stalls, risking internal winding damage.
