If your home is one that has no ductwork, or has an addition or space that requires either more cooling or better temperature control then a Ductless Air Conditioner or Heat Pump is probably the best solution for an optimum comfort solution.
Window or through the wall type Air Conditioners may be an inexpensive option but are noisy and limited to providing maximum comfort levels. They also offer possible intruders an easy way to enter your home. By comparison a ductless system poses no security risks at all.
Ductless air conditioning can be a great solution for:
- Character homes and homes without ductwork
- Cooling and heating for additions
- Computer rooms or warm bedrooms
- Humidity and temperature control for second floor rooms
- Garages and workshops
- Targeted cooling for areas in your home poorly served by existing ductwork
- Areas heated with electric baseboard heaters
- Rooms or spaces that require critical comfort control
The outdoor portion of a ductless unit is much the same as a conventional central air unit in that the compressor and condensing unit are located on a pad or mounted on wall brackets at the side or rear of the home. Ductless condensing units operate at a much lower noise level and offer efficiency levels (seer ratings up to 27) that are much higher than standard systems. Savings on operational expenses will help with your return on investment especially when the heat pump function is used. Spring and fall temperatures down to 15f will most often not require a boiler system or main heating source to be initialized. A heat pump can provide quality comfort heating at less than half the cost of electric baseboard, and up to 50% savings from other gas heating methods.
The indoor portion of a ductless unit is the cooling unit (evaporator) that delivers controlled airflow directly, quietly and independently of any other spaces in your home. By design multiple indoor heads can offer individual zone control (each with it’s own remote) to meet different temperature needs for maximum personal comfort. Both indoor and outdoor units are so quiet that it is sometimes hard to tell if the unit is actually running. At 30 to 40 db , noise levels will usually be no louder than a gentle wind or soft rainfall.
Single zone units are available up to 36,000 BTU or 3 tons of cooling. It is very important if not critical to not oversize on cooling power since humidity removal must be achieved with a long enough run cycle to provide optimum comfort conditions. Dual or three head systems can be sized to match the needs of different sized rooms and still run off of one outdoor unit.
Ductless Air conditioning originated in the orient and was developed to solve comfort issues where overcrowding and limited spaces offered little or no options for equipment placement.
