Frequently Asked Ductless Heat Pump Questions

How does a heat pump work?

A heat pump transfers heat using refrigerant expansion and compression within a cycle…What does that mean? It takes heat out of the outside air and transfers it indoors to make air warm, and then to cool, it takes warm air inside and transfers that heat outdoors. The same system provides both heating and air conditioning. While traditional heat pumps require a backup heating system when it’s freezing in Seattle, ductless heat pumps will still be creating comfortable heat at -4 F, that’s four degrees below zero. That’s why ductless heat pumps are so popular in cold climates such as northern Europe and Japan. You can use 100% ductless heat, or use a ductless heat pump in one area to supplement existing heating or cooling and increase your comfort. Also perfect for older Seattle homes with limited ducting or additions.

Will I qualify for a ductless heat pump utility rebate?

We are excited to offer customers who buy a qualifying ductless system from us a way to improve their return on investment further with a rebate from their local electric utility. The rebate qualifications differ slightly between utilities but here are some common requirements:

  • You must be currently heating your home with electricity. That can be in the form of baseboard electric heating, wall electric heaters, or a forced air electric furnace. It does not include using a big outdoor air source heat pump. The reason that this is the requirement is that the baseboard, wall or forced air furnace when powered by electricity is highly inefficient and uses lots of electricity. You probably have high heating costs in winter. For the utilities, replacing this system with a super efficient ductless system will not only save you on energy costs but saves energy for them too. They are trying to conserve electricity because it costs less to pay you the rebate than it does to build a new electric plant. If you only use a little bit of electricity, for example with an air source heat pump or maybe you have a natural gas furnace with electric in one room of the house (old houses do have this). They will not be able to get much savings …and neither will you. So they do not offer rebates for secondary applications (eg: heating one room).
  • The ductless system uses inverter technology. This is the common technology used in ductless systems so you are unlikely to find ones that don’t meet this. Inverter technology is what makes their heating and cooling energy efficient. It is self adjusting based on the need for heating and cooling so that it saves energy vs running at a constant speed. Daikin is a world leader in inverter technology, which is one of the many reasons we sell their products.
  • Customers of Tacoma Power and Snohomish PUD must have good insulation levels in the home. These requirements vary between Tacoma Power, Snohomish PUD and our Home Energy Specialists will be able to explain them in detail. PSE and Seattle City Light do not have a specific insulation requirement.
  • Systems must be installed by a qualified contractor. As a Master Installer with NW Ductless Project and qualified contractor for all of the major utilities, Washington Energy Services can provide these rebates. There are other requirements that vary by utility and our team will explain them when you meet.

In the Northwest, is a ductless heat pump system really more efficient?

Yes, especially if you have electric, oil or propane heat. Compared to electric baseboard or wall heat, you could see a 25-50% reduction in heating costs (source NEEA, NW Ductless Project). Here’s how a ductless heating system compares with other heating systems. It uses less energy and provides more heat for your energy dollar – now that’s technology at work!

What are the components of a ductless heat pump system?

Ductless systems have 3 main parts

  1. An indoor unit
  2. An Outdoor unit that sits on the ground
  3. A Remote that controls the unit

The indoor and outdoor ductless units are connected by a small bundle of cables including a refrigerant line. Ductless systems have an ultra quiet fan that circulates air evenly throughout living areas eliminating hot and cold spots. Do you want detailed information about ductless equipment?

What are the best ductless heat pump applications?

Applications for the mini split heating and cooling are:

  • Homes heated with electric heat – Ductless heat pumps are an  excellent replacement for any home heating with electric baseboard, wall or ceiling units, and other space heaters, such as propane. You can save up to 50% on your electric heating cost. Significant utility rebates are available for ductless heat pump installation.
  • Remodels and Room Additions – A ductless heat and cooling system is perfect for home additions, remodeling projects and garage conversions. There is no need for duct work and the units are easily installed.
  • Heat that one cold room – Many older homes have insufficient ducting or had previous remodels with no ducts in one area. A ductless system will heat and cool that room or rooms and save you the cost of adding expensive ducting to new parts of your home.
  • Condos are perfect candidates for a ductless system. Quiet, compact outdoor units can fit easily on terrace or patio spaces.

Are there ductless heat pump rebates available in Seattle and Tacoma?

All of our major area utilities have rebates for ductless heat pumps, up to $1200. Washington Energy Services is a master installer of ductless heat pumps and is authorized to provide these rebates on behalf of the utilities. Homes must use electricity as the primary heat source to qualify for a ductless heat pump rebate.  See link for more details. Utility Rebates Available*.

Why do they call it a ductless system?

A ductless split system or ductless heat pump system is “ductless” because it does not use ducts within the house to heat or cool the home. A ducted system has a string of ducts inside the walls bringing forced air throughout your home. The ductless system has indoor registers mounted in main living areas that heat and cool. The reason it’s often called a split system is because there are two components, the outdoor heat pump unit and the indoor register.

Will a ductless heat pump work in a mobile home?

Yes! Installing ductless heating and cooling in mobile homes is easy and we can do that. In some cases, the permitting process is different but we handle that for you. Both our Daikin and Fujitsu products are perfect for mobile or manufactured homes.
