Cal-Green effectively removes dirt, grime, and contaminants from coil surfaces without harsh chemicals, helping restore optimal heat transfer and system efficiency. If your Lennox unit is running longer cycles, struggling to reach set temperatures, or consuming excess energy, fouled coils could be the culprit and Y8574 provides the factory-recommended green cleaning solution.
