Ductless HVAC units are easy to install, flexible, energy efficient, and offer improved indoor air quality. Ductless HVAC units take less time to install, because there are fewer steps involved in the process. The indoor and outdoor units have to be mounted and then connected to each other via cables, power lines, and refrigeration. Ductless HVAC units can be installed in a number of different spaces and configurations. They can be set up as single zone systems or multiple indoor units can be connected to a single outdoor unit for zone control. Ductless HVAC systems are extremely energy efficient. Some models are even designed with variable speed fans. Ductless HVAC units also help to improve indoor air quality. When there isn’t any ductwork in your home, there are dust bunnies and allergens accumulating inside of your home. Ductless HVAC units can be a great choice for apartments, homes, offices, and places where extra cooling is necessary. When I wanted to add air conditioning to the garage, I contacted a company in Arlington Heights, Illinois. My partner and I live in Arlington Heights and we wanted someone local to set up our new heating and cooling system. I wanted an estimate for the charges and the Arlington Heights company offered to give us a free quote and estimate for the services. It was less expensive to go with the ductless system and it would have been to upgrade our central heating and cooling system. It made sense for the two of us to go with a ductless HVAC unit for the garage.
