HVAC in Piedmont.

What we see in Piedmont homes

Climate. Piedmont sits in the Oakland hills, mild and marine-influenced. Summers are comfortable, rarely above the mid-80s, and winters are cool but well above freezing most nights. Cooling has historically been an afterthought here, but more owners are adding it, and the mild climate makes heat pumps an efficient choice for both heat and AC.

Housing stock. Piedmont is dominated by 1910s through 1930s Tudor, Mediterranean, and Colonial estate homes, many large, multi-story, and never built with central AC. Original gravity and early forced-air furnaces are common, along with the structural quirks of plaster walls and finished basements that make duct routing a real consideration.

Typical systems. Estate homes: heat pump conversions on aging furnaces, multi-zone ductless and ducted systems to handle large multi-story floor plans, and zoning to balance the temperature swings between floors. Where existing ductwork is undersized, we re-engineer rather than reuse it.

Why we know Piedmont homes

Piedmont is almost entirely large 1910s-to-1930s estate homes, Tudors, Mediterraneans, and Colonials, set in the Oakland hills. These houses were built for heat, not cooling, so most of our work starts from a system that was never designed for AC. The challenge is always the same: how to add efficient heating and cooling to a multi-story plaster-walled house without compromising the architecture. Finished basements, balloon framing, and undersized original ductwork all shape what we recommend.

What we run into most

Heat pumps are the natural fit here. The mild climate means a heat pump covers both the heating these homes already need and the cooling owners increasingly want, and it does it efficiently year-round. On the larger floor plans we almost always zone the system, because a three-story Piedmont house heats and cools unevenly otherwise, with the top floor running hot and the ground floor cold.

Where running new ductwork through a finished estate home would be destructive, ductless mini-splits do the job cleanly, especially for additions, converted attics, and primary suites. When we do reuse ducts, we check that they are sized for the load rather than assuming the original system was right. A lot of these homes have been limping along on equipment that was undersized or oversized from the start.
