When my husband and I bought our home, we had a very limited budget. We were newly married, struggling to pay off student loans, and not making much of an income. Unwilling to waste money on rent, we found a very small house in need of major repairs. Our little house was perfect for us. We handled the upgrades on our own, and ensured that the house was extremely energy efficient. We installed Energy Star rated windows, added insulation to the walls, ceilings and attic, and put up ceiling fans. Because of our efforts and the minimal square footage, we were able to get by with a small furnace and air conditioner. Our monthly energy bills were inexpensive, and we kept the home at the ideal temperature all year round. Eight years later, we’d added three children and two dogs to our family. We were horribly cramped and needed to put on an addition. The addition nearly doubled the size of the home. There was no way the existing furnace and air conditioner could handle this larger demand. Rather than sacrifice the space and invest in a complete duct system for the addition, we opted to install a multi-split system. The ductless heat pump incorporates a single outdoor compressor linked to multiple indoor air handlers. The indoor handlers are compact, lightweight and mount on an exterior wall. Despite the streamlined design, the heat pump is powerful enough to quickly heat up or cool down the various rooms. The individual air handlers in each room allow customizable temperature control and avoid heating/cooling empty rooms.
