When my hubby plus I purchased a modern home in the historical district, the people I was with and I were delighted with the antique light fixtures, stained glass windows plus hardwood floors, doors plus moldings. The two of us were ecstatic with the high ceilings, big study room plus wide front porch. It didn’t occur to us how taxing the apartment would be to temperature control. The walls plus ceilings are constructed of the original plaster plus lath, plus there has never been any conventional ductwork installed. Any repairs, changes or improvements the people I was with and I make to the apartment needs to be approved by the historical preservation society plus the process is taxing plus time-consuming. The preservation society is legitimately particular about what they will allow. Any modernization is frowned upon. My hubby plus I weren’t eager to take on that fight or the mess plus disruption of installing ductwork. However, our apartment was chilly cold in the Winter time plus boiling plus sticky in the summer. The two of us were trying to manage comfort with electric baseboard furnaces plus window a/cs. The big windows, high ceilings plus overall age of the apartment were making it impossible to reasonablely heat plus cool with portable units. I did some research plus came across high velocity heating plus cooling systems. This category of temperature control is certainally designed to retrofit into older homes that lack traditional ductwork. The system features mini-ducts that are only multiple-inches in diameter plus bendy enough to route through existing walls without disfigure. The ducts are able to accommodate studs, plumbing pipes plus electrical wires. They fasten to round vents that are only six-inches in diameter plus blend seamlessly with the decor. The high velocity system delivers conditioned air at a legitimately high rate of speed to abruptly lower or raise room temperature. This system allowed us to preserve the historical integrity of the modern home plus still prefer centralized temperature control.
