The small-profile mini-splits unburden installation limitations by using a single 3 ½-in. wall opening to connect its indoor and outdoor units, along with the refrigerant, drain, and control lines.
Century's GeoMax2 series geothermal split system heat pumps maximize comfort and efficiency with two stage operation and EERs as high as 29.4 on partial load. Models are available in 2- to 5-ton capacities and can be stacked for multi-unit installations.
The HTV Series uses R-410A and the extended operating range of 20F to 120F entering water temperature makes units suitable for virtually all applications and climates.
Lennox announces the XC17 and XP17 single stage air conditioner and heat pump. The XC/XP17 offers efficiencies as high as 18-SEER, using a single stage scroll compressor design and an efficient composite fan motor designed exclusively for Lennox. In combination with sound-lowering technologies such as a sand-filled compressor sound cover and the new composite fan blade, these new air conditioners and heat pumps can provide year-round comfort and efficiency, while operating at industry-leading low sound levels as low as 62 dB, company sources say.
Mitsubishi Electric Cooling and Heating Solutions, has introduced the split-ductless M-Series Star Lineup, featuring updated indoor and outdoor units designed for maximum energy efficiency. The advanced MSZ-FE lineup includes models that are Energy Star® rated and allow homeowners to take advantage of federal tax credits of up to $1,500. The systems offer high heating performance with operation possible down to minus 13F.
Rheem's Prestige Series™ 27 to 31 EER geothermal heat pump with Comfort Control2 System™ serial communicating feature offers whole-home comfort solutions available in package and split system configurations.
These systems are protected by a 10-year limited warranty and come equipped with an advanced scroll compressor, an ECM variable speed blower motor as well as many other features.
Some benefits of the Samsung Vivace line include the MPI generator, a device which actively generates hydrogen and oxygen ions and removes impurities from the circulating air. A “Good Sleep” mode provides for increased comfort during the night by adjusting the temperature automatically, for a soothing night's sleep.

Sanyo announces six new indoor 4-way ceiling mounted cassette models XMS0972, XMS1272, XS1872, XMHS0972, XMHS1272, and the XHS1872 - to be added to its Flexi-Multi product line. These new indoor models are available in 9,000, 12,000 and 18,000 btu/h nominal capacities. All models are rated at 16+ SEER and 8.5 HSPF for increased energy-use effciencies.
The Trane XL15i air conditioner and heat pump are Energy Star® qualified and built with Trane's Climatuff® compressor, its patented Spine Fin™ coil and other Trane innovations such as:
Full-Side Louvered Panels
WeatherGuard II™ top to protect the unit from debris and damage.
The Westinghouse FS4BI iQ Drive air conditioner uses inverter-driven rotary technology, which is different from traditional air conditioners in that it is almost always running. The unit can modulate anywhere from 40-118% of capacity.
Carrier Corp., has enhanced its product line with a new modular water-cooled scroll chiller designed to cover a wide range of applications. The AquaSnap® 30MP chiller with non-ozone depleting Puron® refrigerant is offered in 15-45 tons, exceeds ASHRAE 90.1 efficiency standards, and is up to 20% more efficient than its predecessors.
LG has incorporated advanced Inverter technology with its line of Multi-V systems which use a variable refrigerant flow (VRF) heat recovery system to operate cooling and heating simultaneously with one outdoor unit for easy temperature zoning. Built around LG's inverter compressors, the Multi-V series delivers one of the highest energy efficient ratings (EER) available in the VRF equipment category, along with low sound operation, sources say.
Adding to its line of Variable Refrigerant Flow Zoning (VRFZ) products, Mitsubishi Electric has enhanced two of its indoor units, the PCFY and the PKFY. The PCFY, a ceiling-suspended unit, is an alternative to utilizing space rather than wall mounts or recessed models. The PKFY unit mounts high on a wall and blends into any space and features a compact and lighweight flat panel design.
The Daikin McQuay® Magnitude™ frictionless centrifugal chiller, known for its advanced magnetic bearing compressor, is available up to 550 tons, making it ideal for mid- to large-size retrofit projects, company sources say.
