Ductless Systems FAQS

What is a Ductless Split System?

A ductless split system is split into an interior unit which includes a fan and is referred to as the evaporator; and an outdoor unit which contains the compressor and is referred to as the condenser. The two units are connected using insulated copper refrigerant tubing and electrical wiring which pass through a 3” diameter hole. These systems are capable of cooling and or heating one or more rooms.

How long have Ductless Split Systems been around?

Ductless Split Systems were developed in Japan in the 1970’s and have grown to become a preferred cooling and heating system throughout Asia, Europe and other parts of the world. Over the past 25 years, interest in the Ductless Split System equipment has grown in the United States.

What are the advantages of installing a ductless split system over a window or wall air conditioner?

The ductless split system is almost silent when running, unlike a room air conditioner. The technology used in ductless split systems is very sophisticated so that they deliver precise temperature control. The variable speed compressors in ductless split systems utilize maximum electrical efficiency by delivering only the amount of BTU’s required to cool the room, not the maximum BTU’s the unit is rated for. The ductless units are mostly installed over or next to a window or doorway, so they do not block the window view or allow cold drafts in winter.

What are the advantages of installing a ductless split system over a central ducted system?

A ductless split system does not use ductwork. The heated or cooled air is delivered right into the room for maximum efficiency and precise temperature control. Ductless split systems are useful if a room is added to an existing house or when there is a too hot or too cold room in a house that already has central air. Ductless split systems cost less to run and are more energy efficient than central systems since you have the choice to cool or heat a specific area, not the entire house.

How do I choose the ductless split system that is right for my application?

A single zone ductless split system (one evaporator and one condenser) will cool or heat one area. If you want to cool or heat more than one area, multiple indoor evaporator units can be connected to one multi-zone outdoor condenser unit. Talk to an experienced professional to find out the best solution for your application.

Are there any incentives available for ductless systems?

Local utility company’s like Con Edison and LIPA may offer incentives for purchases of ductless split systems with high SEER and EER.

What is the life expectancy of a Ductless Split System?

With proper maintenance and care manufacturers suggest the ductless split system equipment should perform for 20 years or more. Weston Bros. has installed systems still working well for that length of time.

Where and who should I purchase a ductless split system from?

A consumer should purchase a ductless split system from a manufacturers’ authorized contractor such as Weston Bros. The authorized contractor will have a high level of technical training and is extremely knowledgeable about the product and the installation requirements for each specific model. The authorized contractor has proven experience with ductless split systems and provides the best solution for any particular application.

What is SEER?

Seasonal Energy Efficiency Ratio is a measurement of energy efficiency for air conditioners and heat pumps over a period of time. The SEER rating of a unit is calculated by dividing the cooling output during a typical cooling season by the total electric energy input during the same period of time. The higher the SEER number is, the more energy efficient the equipment is. Higher Energy Efficiency equates to lower electric bills.

What is a BTU?

BTU – British Thermal Unit, is a scientific term representing the amount of energy required to raise one pound of water one degree Fahrenheit. One BTU is the equivalent of the heat given off by a single wooden kitchen match. For your home, it represents the measure of heat given off when fuel is burned for heating or the measure of heat extracted from your home for cooling. The larger the area you need to cool or heat, the more Btu’s you will need.
