Daikin Ductless Split Systems

Heating & Cooling From
The World’s Leading HVAC Company

When it comes to home comfort, no one knows more about it than Daikin®, the world’s leading HVAC manufacturer. Heating and cooling is what they do, and it’s all they do. They don’t make cars or appliances(as some of their competitors do).

Daikin is a leading innovator in advanced air conditioning and heating for homes, businesses and industrial use.  With almost 90 years in operation, and a strong commitment to quality, they have become the largest manufacturer of HVAC systems and refrigerants in the world. Their systems are in millions of homes in 90 different countries. And their specialty is ductless heating and cooling.



Fox’s Heating & Cooling Specialists recommend top ductless systems from Daikin that provide excellent heating & cooling.

SEER stands for Seasonal Energy Efficiency Ratio. That is the ratio (fraction) of the cooling output of a particular piece of equipment over a whole cooling season, divided by the total electric energy needed to run it. The higher the SEER rating, the more energy efficient it is. The government has set a standard of a minimum of 13 SEER for all new air conditioning equipment sold in the US after 2006.

HSPF stands for Heating Seasonal Performance Factor. The HSPF rating is specifically for heat pumps. It measures the ratio of the heat output of the unit (BTUs) over a whole heating season divided by the watt hours of electricity used. The higher the rating, the more efficient the heat pump.

Because ductless and air source heat pumps provide both heating and cooling, your heat pump will be rated on both SEER and HSPF.


There are several factors that determine the cost of a Daikin ductless heat pump system.  Three of the primary ones are:

The first is proper sizing of the ductless heat pump components to fit your home, condo or townhouse.  That is a little different than sizing for an air source heat pump, as the house layout has to be considered.  The house is broken down into “zones” – which are essentially the areas that can be covered by a single indoor unit. The number of “zones” and capacity of the system affect price, along with any special features you desire. Your Fox Heating & Cooling Specialist will explain more and work with you to size the optimal split system.

The second factor is the special features you choose to have in your system. Daikin provides a range of products from the basic 15 Series to the mid-range LV series up to the top of the line Quaternity series. The features of these products can be found in the Single Zone Specs and Multi-Zone Specs links and your Fox Heating & Cooling Specialist can provide you with more detail. Some of the highlights include:

  • Wireless remote temperature and humidity control
  • Unique air cleaning technology
  • Ability to produce heat down to very low temperatures, even -4F!
  • Standby and economy modes
  • Motion sensor technology to lower operation when no one is in the room
  • Ultra-quiet operation

The final factor will be the complexity of the installation, including any needed electrical work.  The quality of the installation is important in ensuring the proper performance of your ductless system. That’s why Fox’s Heating & Cooling team focuses on continuous training with Daikin representatives to ensure a smooth ductless heat pump installation and service.
