Advantages of ductless mini-splits for whole home heating and cooling year round. The United States Department of Energy states that nearly 50% of utility bills go towards heating and cooling the home. Mini-splits offer faster payback than other traditional heating cooling systems. The high-efficiency of mini-splits along with their true zoning capability have proven to reduce heating and cooling bills by as much as 50%. This represents a 25% reduction in total utility costs. Mini-split systems offer year-round heating and cooling comfort, even in cold climates. Soft start up and whisper quiet operation. Spot cooling for room additions, hot/ cold spots, server rooms. Inverter technology - Our mini-splits are so efficient and quiet because of inverter technology. The inverter converts AC voltage to DC voltage through a diode bride (bridge rectifier) allowing power consumption to be modulated to nearly zero levels. Single-zone mini-splits allow easy addition of heating and cooling to specific areas in the home. Room additions, hot and cold spots, and remodeling can present challenges in terms of adequately heating and cooling these spaces. Ductless minisplit systems are the perfect solution to provide year-round comfort. These high-efficiency heat pump systems also provide tremendous energy savings. Available in Cooling-Only models for warm climates, computer server rooms, garages, sun rooms, or anywhere additional cooling is desired.

True Zoning Throughout Your Home Multi-zone mini-splits allow each space in the home to be individually controlled, potentially saving hundreds of dollars on energy bills. Multiple indoor units are attached to one outdoor unit for a clean, easy, attractive installation. Indoor Evaporator 21 C 27 C 24 C Outdoor Condenser With multiple systems throughout your home, airflow can be selectively channeled where it s needed depending on changing climate conditions or activities during the course of a day. For example, you may choose to keep a bedroom cooler than the family room at night. By only conditioning selected areas according to need, you can lower your overall utility costs. Aside from lowering utility costs, multiple systems can also help with other problematic scenarios. Vaulted ceilings, great rooms with connected kitchen and dining spaces, expanses of glass windows exposed to the sun from the south and/or winds from the north, and sprawling ranches with hard-to-reach rooms can all benefit from separate cooling systems in each area.

Installation Techniques What You Need To Install Ductless Mini-Splits At their core, ductless mini-splits are still a simple refrigeration system. They just use advanced technologies like inverters, electronic expansion valves, and numerous sensors in both the indoor and outdoor units to modulate and maintain comfort in more efficient manner than conventional systems. Flare Nut Torque Wrench Regardless of your experience in the industry, there are a few important tips that will help ensure a high quality trouble-free installation with NO CALL BACKS. Invest in the Right Tools - Trying to do the job right is nearly impossible if you don t have the right tools. 45 Flaring Tool Flare Nut Torque Wrench Torqueing to proper specs is essential to a quality installation. Leaks can occur over time with expansion and contraction if not tightened to the proper specs. Multi-Meter with Diode Setting and Needle Probes Mini-splits convert incoming AC voltage to DC through a diode bridge (bridge rectifier). The ability to check diode functionality is essential to the troubleshooting process. Standard meter probes cannot get into small harness casings. Meter with Diode Setting/ Needle Probes 45 Flaring Tool - Residential mini-splits are connected with flare fittings. Reason: the systems are only equipped with a small strainer to keep large debris out of the compressor. We do not allow soldering because debris can plug the strainer or damage the compressor. We do not allow filter dryers. Do you know that R410-A flare fittings are 45? This means your standard 37 flaring tool will not make the proper flare and may leak. Residential.

Heat Pump Models Intelligent Defrosting Maximize heating comfort with shorter defrosting time. Traditional defrosting works by setting time, e.g., defrosting process is on for 10 minutes at each 50 minute interval. Westinghouse I-Defrosting is only performed when needed, which reduces energy waste by eliminating the unnecessary defrosting process. Westinghouse I-Defrosting Traditional Defrosting Functions for Low Ambient Temperature 8 C (46 F) Heating Freeze Protection Maintain the room temperature steadily at 8 C (46 F) and prevent winter freezing when room is unoccupied for long periods. -15 C (5 F) Cooling - Reliable operation at -15 C (5 F) cooling. As the outdoor temperature changes, the frequency of compressor and the speed of fan adjusts accordingly. -20 C (-4 F) Heating - Reliable operation at -20 C (-4 F) heating is supported by Westinghouse s electrical heating chassis, preheating technology and system modulation. Cold Air Prevention Fan delay allows the copper pipe to be heated in advance, so the air will not be blown out before it reaches the set temperature. Residential. Light Commercial Catalog - Page 32
