The Smart Frog air conditioner offers high-efficiency variable-speed performance in a small cabinet and provides up to 23-SEER cooling efficiency. Its variable-speed inverter capacity control delivers operation for load matching, dehumidification, and zoning performance.

Bob and Tim just arrived at the house of a new customer. The customer explained to them that he just started up his air conditioner for the first time this spring. There was a warm spell, and the system didn’t work. As a matter of fact, it didn’t cool — the outdoor unit did not run at all. Bob explained to the customer that they would get started looking at the system and figure out what was going on.

The XR16 is a low-profile side-discharge air conditioning unit for split ducted systems. The unit is available in 1.5- to 5-ton sizes. It is designed for challenging applications, including zero lot-line situations, multifamily housing, and condominium units and row houses.

Originally designed to support an occupancy level of 850 people, the Arcbest corporate headquarters has grown to now have 1,085 people plus visitors. Ten percent of the people work at night, requiring 24/7 air conditioning. The increase in occupancy drove a need to introduce more outside air to maintain air quality. All of this outside air had to be conditioned, increasing electrical energy costs. In addition, the extra outside air caused draftiness on cold winter days, and, during the summer, the extra outside air flow through the air handlers resulted in some parts of the building getting too cool. 

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.”
