It’s hard to believe that an experienced architect could forget to plan for the HVAC system when designing a custom home, but it happens more often than you would think. Once the oversight is discovered, the builder must scramble to fit in the HVAC unit, and this doesn’t always result in optimum performance. The home may have been designed without room for ductwork, or it may have numerous features that will make it a challenge to cool and heat.
Here are some architectural features that make it challenging to condition the air.
It is hoped that the trend toward building huge homes will wane and the trend to smaller, more efficient dwellings will continue. But there are likely to still be some holdouts for 20,000-square-foot McMansions, and those will continue to be challenges for HVAC professionals. A large home will usually require two (and maybe three) HVAC systems. There’s lots of opportunity to mess up the ductwork design so that parts of the home are too hot and parts are too cold. Zoned systems may be a solution.
Even if a home isn’t way oversized, builders can create the sense of space by adding vaulted or cathedral ceilings. While they do add grandeur to a home, they also make it hard to heat or cool. As cool air pushes warm air to the high ceiling, the air on the second level may become extremely warm. One way to counteract this difficulty is to include a return register at the level of the vaulted ceiling, so the warm air can be drawn out and cooled before it is dispersed into the home.
Big windows can be an asset when selling a home, particularly if they look out over a stunning sunset. But that hot setting sun can make it a challenge to cool your home. A zoned system can help cool down the room with the windows, as can large ceiling fans or even a ductless mini-split exclusively for this part of the home.
