I recently bought an old farmhouse with the intention of complete renovation. That complete renovation is now in its third year. Really, what was I thinking. There have been so many hurdles and challenges to overcome. Structural integrity was sound but it seemed as though everything else needed replacing. The HVAC heating system was on the replacement list. My farmhouse is located in a part of the South where winter is fairly mild but chilly months exist. Yet, the ancient oil furnace was no longer up to the job. I knew an investment in a new heating and cooling system would require a trusted HVAC professional. I phoned a local heating and cooling company to have my situation carefully considered. The HVAC technician showed me several heating and cooling options. But he leaned heavily toward investing in a heat pump. The heat pump could be married up with the current duct system with a little retrofitting. I was worried though about heat in the winter. Stories about weak heat pumps and shivering home owners had scared me off the heat pump. However, now that I was much further south, perhaps a heat pump was the way to go. The HVAC tech put me at ease when he explained a few details. The heat pump could actually work on its own by pulling heat from the outside air. The heat pump alone was sufficient down to about forty degrees. On the rare occasion the temps fell below forty, an electric heating panel would help supplement the heat demand. And, of course the heat pump is the most efficient cooling source out there. I picked the heat pump and have checked another thing from that renovation list.
