Bob and Tim were on their last service call for the day. It was an apartment house with a heat pump and the weather was warm during the day and cool at night. The tenant had just moved into this apartment and was trying to get the air conditioning to operate to her satisfaction and she said it was too breezy.
Bob and Tim were at the house of a customer who said that her air conditioning unit did not cool well in the hot weather three days ago. She said the unit actually froze up and had ice on the outdoor portion of the unit on the big line. She shut the unit off and called for service.

Bob and Tim had just finished a routine service call on a house with a gas furnace for the heating system. They were talking to the housewife when she asked: “Our house is very dry in the winter time, and the humidity must be very low. How can we put a system in this house to keep the whole house at a higher humidity level?”
Bob and Tim were driving to a service call where the customer’s complaint was that her home’s windows were sweating excessively. Tim asked, “What could be some of the reasons that a customer’s windows would be sweating?”

After doing a visual inspection at the air handler, they moved to the roof to give the outdoor unit a visual inspection.
Bob and Tim were called to a heat pump problem where the homeowner said the unit was icing up in her basement. When they arrived, the housewife met them at the door and took them down to the basement and said, “This is not normal. I have never seen ice down here on these lines before.”
