HVAC for Remodels, Renovations, and Design-Sensitive Homes

Yes — whole-home gas-to-electric conversions are a core part of our work. We size heat pumps for calculated heating and cooling loads, plan electrical capacity, and coordinate distribution — not a same-size swap based on your old furnace label.

Modern cold-climate heat pumps perform well in Bay Area winters and summers when sized with Manual J and installed with proper distribution. Coastal microclimates and inland heat spikes are why we engineer each home — not assume one product fits all.

We are Mitsubishi Electric specialists and design around the best technology for your home — ducted, ductless, or mixed layouts sized with Manual J/S/D, not rule-of-thumb equipment swaps.

Manual J is the ACCA standard for calculating heating and cooling loads room by room based on your home’s envelope, windows, orientation, and local climate — not square footage rules of thumb. We use it to size equipment and duct systems so your system performs in real Bay Area conditions.

Square-footage rules ignore insulation quality, window area, shading, air leakage, and how your home actually gains and loses heat. Oversized equipment short-cycles, wastes energy, and struggles with comfort and humidity. Manual J matches capacity to measured loads.

Manual S selects HVAC equipment that matches Manual J loads without oversizing. Manual D sizes and lays out duct systems for proper airflow and static pressure. Together with Manual J, they form the engineering backbone of our design-build installs.

Yes. Permit, Title 24, and inspection coordination are part of our design-build scope — not a surprise add-on at the end. We retain load calc and equipment documentation your jurisdiction and rebate programs commonly require.

No. We focus on project-based residential HVAC — heat pump installations, full-system replacements, remodels, retrofits, new construction, and ADUs. We do not provide emergency repair, routine maintenance, tune-ups, filter changes, or small service calls.
