Why Time Delay Relays Matter
Time delay relays are essential control components in modern HVAC systems. By introducing a controlled pause between operational stages — such as compressor startup, fan activation, or burner ignition — they prevent harmful short cycling, reduce electrical stress on motors and compressors, and help maintain consistent system performance. Using a genuine York replacement ensures your system operates exactly as designed.
