Carrier

Carrier geothermal heating and cooling systems offer high efficiency for low operating costs, company sources say. Since geothermal units contain few moving parts, these heating and cooling systems can operate efficiently for years with little maintenance. The highest quality components have been chosen for their long-term dependability, and Carrier spokespersons say geothermal loops have a life in excess of 50 years.

With the optional hot water generator, hot water is produced when the geothermal system is running in either heating or cooling mode.

Carrier geothermal systems can be connected to existing furnaces or installed with a new air handler to heat and cool the entire home. Because it can be connected to fossil fuel or electric furnaces, the geothermal system is ideal for “add-on” installations, sources report. Visit www.carrier.com for additional info.

Daikin

Daikin’s flexible multi-split systems can serve from two to four rooms (or zones) using only one outdoor unit, and allow individual control of the heating and cooling in each space. Contractors can choose from duct-free, wall mounted units or slim ducted fan coil units, which can be installed in a soffit or the ceiling. There are a number of duct-free and ducted fan coil units to choose from as well. There are a total of 115 possible combinations.

According to company sources, the two-port and the four-port multi-split system is ideal for installations where space for outdoor units is limited.

Daikin’s inverter technology offers energy efficiency with SEER ratings up to 19.5 and HSPF ratings up to 9.6.Units are optimized for R-410A refrigerant.

Daikin’s multi-split systems feature Home Leave Operation, which allows homeowners to adjust the temperature and airflow rate with a push of a button. The Intelligent Eye, an infrared sensor that can sense human movement in the room, is available on Daikin’s wall mounts. After no movement is sensed for 20 minutes, the system sets back the temperature to reduce power consumption. Visit www.daikinac.com for more info.
