Boston Ductless Systems installs heat pump systems for energy-saving air conditioning and heating in your home or office. Ductless Air Conditioning Systems, often referred to as heat pump air conditioners, are the ideal solution for the many homes and buildings that do not have pre-existing ductwork installed. Did you know that Duct losses can account for more than 30% of energy consumption for space conditioning? Since heat pumps have no ducts, they avoid the energy losses associated with ductwork of central forced air systems. There are five options for these systems. We will help guide you to what system will work best to suit your needs. BDS provides complete installation including the electrical work. MA State Electrical Licensed.
