Ductless cooling was first invented by Daikin in 1973. These systems which are sometimes referred to as ductless mini-splits or mini-split systems have become extremely popular in the last decade. What was once an answer to adding a cooling system to a home with no ductwork has quickly become a solid alternative for many other reasons such as

  • Supplement to areas with insufficient heating and cooling
  • Eliminate noisy ducted systems
  • Diversity of usage in larger homes with many unused areas

Since then technology has changed to make this an attractive first option.

Benefits of ductless systems include:

  • No ductwork required
  • Small equipment footprint
  • Significantly lower energy usage than conventional ducted systems
  • Easy zoning increases savings by cooling only the rooms you are using
  • Consistent room temperatures
  • Less equipment short cycling
  • Better humidity control
  • Higher comfort level
  • Ductless heat pump systems for residential applications provide both heating and cooling

Like any mechanical system, the most important part of the project is the application and installation of the equipment. Ambrose Mechanical will help you select the best system for your home’s application, then our trained technicians will perform the installation to provide you with a system that will offer quality comfort, energy savings, and long service life.

Ambrose Mechanical has been successfully installing and servicing ductless systems for over 20 years

A: There are manufacturers and others on the internet who over-simplify the installation of a ductless system. If the system is sold with pre-charged, quick connect refrigerant tubing, it is possible however since cutting the tubing to length is not possible the end result will not look like their pictures. In addition, these connections do not last as long as mechanically flared connections and if there is a problem with the O-ring seal at the time of installation you have a real mess on your hands. The labor warranty for any problems encountered at the time of installation and the first year is usually covered by the installing contractor, so if that’s you, you may be dealing with something totally beyond your ability.

A: No. Ductless system are incredibly quiet. Indoor units operate in the 40-50 dB range and outdoor units in the 50-60 dB range which is about the same as a new refrigerator.

A: About 20 years if properly installed.

A: No. The initial installation will be mor that a conventional ducted system, however, the increased efficiency (SEER rating) represents a savings of usually 30-50%. In addition to that the ductwork losses of a conventional system can be as much as 30% and with easier system zoning the usage diversity of only conditioning the areas as needed helps save a lot more money. Over the life of the system this savings can exceed the original expense.
