In this month’s troubleshooting situation, you are dealing with a 4-ton split system, and the locale is a desert Southwest city. The customer in this case is the landlord, and they are working on the residence, getting it ready to rent after the departure of a long-term tenant. Their description of the problem is that the house “just won’t get comfortable.”
When they called, they asked for an estimate of what it would cost to get a ”Freon” charge because they knew that the system had never been serviced since it was installed. They also told the dispatcher that the day before, when they decided to check the filter, they found that there wasn’t one in place, so they installed a new one.
