Ductless mini-split heat pumps consist of an indoor and an outdoor unit connected by copper tubing and an electrical supply. Both are controlled by a hand held remote control. The outdoor unit collects heat from the air outside and transfers it to the indoor unit. Some high SEER Systems are able to provide heat with an outside temperature of -25 deg C. (slide 1 above)
In the summer the system works in reverse to transfer heat and humidity outside providing a comfortable cooled living area. Since there are no air ducts involved, the system efficiency is greatly increased while remaining extremely quiet while operating. (slide 2 above)
Before purchasing a ductless mini-split it is important to discuss the items listed below. Bonnevie Refrigeration will be pleased to meet with you to answer any questions as well as offering a quotation on a unit that would best suit your needs.
SEER is an abbreviation of Seasonal Energy Efficiency Rating. It is a measure of the seasonally adjusted cooling output of a unit divided by the energy consumed. The higher the SEER rating, the more energy efficient the unit is. The minimum SEER rating for new air conditioners is 13 SEER. The newest units have SEER ratings greater than 25. Look for the highest rating to ensure the greatest savings on your utility bill.
HSPF stands for Heating Season Performance Factor. HSPF is similar to a SEER rating in that it measures the heating output vs. the energy consumed by the unit, adjusted seasonally. It helps one compare the heating season efficiency of various units. The higher the number, the more efficient the unit. Most "1:1" or "single" heat pumps (meaning that each outdoor unit has only a single indoor unit attached to it) should be able to achieve 10.0 or greater. The newest units have HSPF ratings greater than 13. These higher ratings will guarantee the greatest savings on your utility bill.
