When ductless cooling and heating units first became popular, they had one very serious limitation – they were not recommended for homeowners in extremely cold climates. Many manufacturers would recommend that homeowners who live in northern regions adopt a supplemental heating source for extremely cold days, which cancelled out the energy efficiency of the unit. Many ductless systems were actually designed to shut down at -10º F in order to protect the technology from failure. This left homeowners using expensive heat pumps, space heaters, and even dangerous propane tanks to heat their homes.
HOW DOES IT WORK?
Traditional split systems lose heat energy in the outdoor coil. Thanks to recent advances, INVERTER® technology is able to collect that energy, helping the system to continue to operate at capacity in extreme temperatures.
In cold climates, heat pumps typically experience a decrease in pressure, refrigerant flow rate, and operational capacity. INVERTER® technology actually allows for higher heating speeds at a lower temperature, without putting extra strain on the unit or potentially causing long-term damage to the compressor.
Some of the differences between traditional technology and INVERTER® technology that make it attainable for those who live in cold climates include:
Consistent Room Temperature – No Ups and Downs, Ons and Offs: Conventional heat pumps experience uncomfortable and extreme temperature fluctuations while INVERTER-driven pumps are able to self-adjust, providing consistent room temperature, even when the outdoor temperature dips below zero.
Consume Only The Energy You Need: INVERTER® zoning systems deliver only the amount of hot air needed to achieve the desired temperature – no more, no less.
Heats Up Quickly: It takes traditional systems a very long time to reach the desired temperature, while the high rotation speeds of INVERTER® systems allow for quick and efficient heating and cooling.
Energy Use is Even and Steady: Every time the compressor turns on in a traditional unit, energy consumption surges. On startup, INVERTER® systems use less current, avoiding spikes in energy usage.
