Hearth and Chimney technology has changed since "August West" first started advertising in Mother Earth News in the 1970s when your only choice was a metal box and a brick chimney. Modern hearth appliances have stringent installation requirements, UL Listings, and complex electronics and circuitry. Today's "modern sweep" is a technician who needs a knowledge of psychics and electronics as well as fire codes.

Our classes are designed to help you increase your productivity, the services you can offer your customers, and your bottom line.

Selling a stove/insert creates a customer, providing professional service after the sale keeps them. Happy customers are repeat customers, and provide referrals.

Many companies lose money on service calls because the technician does not truly understand how the product works, and how to diagnose issues. (Removing parts and slapping in new ones until "something works" is a waste of time, expensive parts and makes your company look like they have no idea what they are doing. Hardly the professional, competent image you want to present).

Even your initial phone conversations with a customer who has a problem will be more effective, as you will know what questions to ask to narrow down the diagnosis before you leave the shop, and what parts and tools you need to bring. This cuts down on repeat service calls for the same problem, which in turn keeps you from losing money on service.
