The DC inverter heat pump is slowly becoming the mainstream choice of most residential and commercial entities. Why? Because the inverter technology makes the heat pump highly energy-efficient and works towards automatic adjustment of the output.
Characteristics of the Inverter Heat Pump

1. Energy Efficiency
The inverter heat pump is a smarter way of working; helping adjust the speed of the compressor in accordance with the temperature. The non-inverter heat pump will keep switching on and off as and when the temperature of the place goes up and up to the set temperature, respectively. But not the inverter heat pump – it will keep operating even when the temperature is at the set temperature – though at this stage the compressor will be consuming minimal energies. However, this is still more energy efficient than the non-inverter heat pump switching on and off.

2. Effective Operations
The inverter DC pump does not switch off any time during the operation of the compressor. So, even when the temperature inside the room reaches the set temperature, the heat pump operates at low frequency. As a result, indoor air is still pleasant and bearable. While the standard on/off pump shuts down once the temperature reaches the set temperature; therefore, after some time the air inside can start to feel stuffy and uncomfortable. This is one of the main reasons why an increasing number of commercial and residential owners prefer the inverter technology-powered heat pumps, even though the machines are costlier than the ones fitted with the on/off heat pumps.

3. Heating Efficiency at Lower Temperature
When the heating efficiencies are compared between the inverter DC pumps and the non-inverter pumps, it has been found that though at the room temperatures, the efficiencies are almost the same; at the lower temperatures, the heating efficiency of the inverter heat pump is way more – almost 60% to 80% more than the non-inverter pumps.


The commercial air source heat pump extracts heat from the air, heating and cooling a home or a building effectively and efficiently. When at its best performance, the HP has the capacity to deliver at least three-and-a-half times more heat to your place compared with the electricity that it consumes. With the advent of technology, the commercial heat pump is now being used to a great extent in the colder parts of the country to provide heat to a building or commercial space. In order to select a heat pump, look at these features:
- Ensure that the heat pump has a demand-defrost control system.
- Choose a heat pump which has an outdoor sound rating of at least 7.6 bels or maybe lower. This will keep the noise to the minimal. The rest of the noise can be handled by keeping the outdoor unit on a base that is made for absorbing noise.
- Also, you need to make sure that the outdoor unit has protection from high-speed winds.
- If this is for a colder region, it is important to choose a heat pump that has higher HSPF or the heating season performance factor is high.
