Trane®, a global provider of indoor comfort solutions and services and a brand of Ingersoll Rand, is now offering the XR16 Low Profile Heat Pump, a side discharge, single-stage heat pump designed for split ducted heating and cooling systems.

New Smart Equipment Controllers (SEC) from Johnson Controls use a smart mobile device interface, giving contractors, engineers, and building owners the flexibility to easily access their Johnson Controls water-to-air water-source heat pump controls through any Wi-Fi-enabled device and internet browser.

Whether heating or cooling, Bosch’s inverter heat pumps keep homeowners comfortable by providing indoor temperature and humidity control.

This side discharge, single-stage heat pump was designed for split ducted heating and cooling systems where space constraints make vertical discharge units difficult to install.

The ZQYRA design offers a simplified approach to dedicated outdoor air systems (DOAS) with only basic options. The patented ZQYRA–8 and ZQYRA–12 units combine superior control design with modulating heat pump and enthalpy wheel technology.

The N4H6 Performance 16 heat pump is an energy-efficient, two-stage model, achieving up to 17.5 SEER/13.5 EER cooling efficiency and up to 9.5 HSPF heating efficiency.

The outside temperature was 40°F, not really cold for the season but the humidity was high in the air. Moisture had just seemed to be laying in the air for several days. Bob and Tim were called to a residence which reported a frozen heat pump. They arrived and talked to the housewife and she said, “My heat pump outdoor unit is a solid block of ice. When I look at my neighbors outdoor heat pumps they don’t look like mine. I think something is not right." They all went to the window in the dining room and looked down on the heat pump outdoor unit and sure enough it was loaded up with ice.

Bob and Tim are on their first service call for winter. They are at a retail store that has 4 units to heat and cool the store. They are all 15 on heat pumps. One area of the store is not heating or cooling well and during the heating cycle, the heat pump auxiliary heat light is staying all for long lengths of time.
