In this month’s troubleshooting problem we have a customer who can only tell us that their heat pump “isn’t working” and “the temperature in the building isn’t right.” When you arrive, you confirm the system isn’t operating properly.

Bob and Tim have arrived at a “no cooling” call at a commercial building location. They went first to the thermostat and noticed that the indoor fan was running, but there was no cool air coming out of the air registers.
In the first part of this three-part series, we talked about the effect cold shortness has on the use of cast iron in refrigeration equipment. Now we will look at porosity and abrasion resistance.
As the Occupational Safety and Health Administration (OSHA) beefs up its whistleblower program, employers should brace themselves for more claims and investigations.
