Ductless Air Conditioners

Keeping Your Office and Home Cool

air conWe are now in the midst of summer, and people are searching for ways to keep their dwellings and offices cool. Around the house, keeping the occupied space cool might be more of a convenience than a necessity, but in an office it is required. Visitors to the office such as customers do not want to suffer through a long meeting in a hot office. Moreover, workers tend to me more productive if the temperature is comfortable. Temperatures that are too high cause worker fatigue and reduced output. Workers may even nod off from the excessive heat.

However, not all homes and offices are equipped with air conditioning. And installation of conventional ducted air conditioning can be cost prohibitive, if not impossible to achieve. As an example, consider an old office building with brick walls and poured concrete floors. Installing standard ducted air conditioning will be expensive due to the labor required to cut holes through the floor and walls for ducts. Additionally, depending on the locality, a structural engineer may have to approve the plans to validate that the floor can still carry its rated load after having the holes for the ducts cut into it.

So this is a situation where ductless air conditioning can be perfect for the application. As implied by the name, this type of unit does not need standard forced air ductwork. Rather, the system locates the evaporator in a unit containing a fan that mounts on a wall. The refrigerant then recycles to an outdoor unit, which could be mounted on a concrete pad at ground level, or alternatively on a roof. The outdoor unit contains the air conditioning compressor and the condenser. So without needing ductwork, these units are a popular cheap air conditioner option.

Ductless units are available in a range of styles and BTU capacities. Small mini units can cool small bedroom, while larger units may be capable of cooling a large office or retail space. The efficiency of these units is good, and installation costs can be quite a bit less than conventional systems. So these factors must be considered in calculating the total cost of ownership over a useful life of twenty or even thirty years. Additionally, if the unit selected is Energy Star qualified, additional credits, rebates and tax deductions may apply. Sometimes local utilities will give additional rebates for Energy Star qualified appliances, particularly if they are replacing an outdated, old, inefficient model.
