Two customers. Customer A had me add AC to her house locally. In a few months we'll be going up to another house she's building to install central heat. Customer B had me install two Trane XV 90 furnaces in his house last fall and is going to have me install two new condensers, evap coils and duct systems in the not so distant future.
I don't know for certain. But it's entirely possible that they had the impudence to disturb the relaxing tradesmen here with some questions prior to doing business with me.
