If you had already ruled out air conditioning, assuming it would cost too much on a monthly basis, it may be time to reconsider your stance. That's because, like so many other technologies, HVAC has improved by leaps and bounds in recent years. Some of the latest climate control options boast jaw-dropping energy efficiency. Perhaps most intriguing are the leading-edge ductless systems made by Mitsubishi Electric Cooling & Heating (Mitsubishi Electric). Popular in Europe and Asia for decades, ductless systems are streamlined and compact, usually consisting of two main components—an outdoor condenser and an indoor unit. Between the two, technicians simply run a pair of thin refrigerant pipes to complete the installation. Straightforward and nonintrusive, the process usually takes less than a day. Once up and running, Mitsubishi Electric ductless systems run at extraordinarily low cost while providing unparalleled comfort. Their versatility is another virtue that homeowners tend to appreciate. Across the full line of Mitsubishi Electric systems, some outdoor units are capable of accommodating multiple indoor units. That means, in the future, if you wanted to extend the comfort of your ductless system to a new room (or set of rooms), it would be easy to do so—without needing to replace the entire system. This time of year, if any rooms in your home are out of step with the temperature elsewhere, give serious consideration to Mitsubishi Electric.
