Our NATE-certified technicians understand SF's architectural diversity and microclimate challenges, providing expert heat pump and ductless solutions. As a fully licensed HVAC contractor, we meet all local codes and historic preservation standards.
We specialize in San Francisco's unique challenges: historic homes without ductwork or central heating, dramatic microclimates requiring neighborhood-specific solutions, space constraints in urban properties, and environmentally-conscious homeowners seeking all-electric heat pumps. Our team provides expert guidance, custom solutions, and meticulous installations. We're available 24/7 for emergencies. Regular maintenance ensures peak performance in SF's demanding climate.
To make HVAC upgrades accessible, we offer flexible financing with convenient monthly payments (on approved credit). Whether you're adding ductless heat pumps to a Victorian, upgrading from old wall heaters, or installing climate control in an ADU, we'll help you find a payment plan that works.
San Francisco's iconic Victorian and Edwardian homes, along with its unique microclimates, create specialized HVAC needs. Most older SF homes lack central ductwork, making ductless heat pumps the ideal solution-delivering efficient heating and optional cooling without costly renovations or compromising architectural character. Many SF homeowners are upgrading from outdated wall heaters and baseboard systems to modern, efficient heat pumps.
We serve San Francisco's diverse commercial sector, including restaurants and retail throughout the city, tech offices in SOMA and Mission Bay, historic buildings downtown, medical facilities, and residential buildings. Our commercial team handles rooftop units, multi-zone ductless systems, and specialized applications with 24/7 emergency support.
San Francisco's microclimates are legendary: western neighborhoods (Sunset, Richmond) stay cool and foggy year-round (often 55-65°F), while eastern and southern neighborhoods (Mission, Potrero Hill, Noe Valley) enjoy significantly warmer, sunnier weather (often 10-20°F warmer). We recommend ductless heat pumps that provide efficient heating for cool SF mornings while offering optional cooling for those occasional warm days. SF's environmentally-conscious residents especially appreciate heat pumps' all-electric operation and zero fossil fuel emissions.

Installed a Mitsubishi multi-zone ductless heat pump system (model MXZ-4C36 with 4 wall-mounted units) in a classic 1920s Edwardian home in Noe Valley. The homeowners wanted efficient heating and occasional AC without disturbing the home's original character or installing ductwork. The new inverter-driven system provides individual room control, efficient heating during cool SF mornings, and reduced energy costs by 42% compared to old baseboard heaters.
Replaced aging wall heaters and window AC units with a Daikin ductless multi-zone system (model MXZ-3C30 with 3 zones) in a Mission District Victorian flat. The new system provides efficient heating, cooling for sunny Mission days, and independent temperature control for each room. The homeowners appreciate the whisper-quiet operation, modern comfort, and 38% reduction in energy costs.
Installed a Lennox variable-speed heat pump system (model EL18XCV) with ducted air handlers concealed in the ceiling of a renovated Pacific Heights Victorian. The advanced system provides efficient heating year-round with optional AC for warm days, operates nearly silently, and qualified the homeowner for $2,100 in heat pump rebates and federal tax credits. The installation preserved the home's historic character while delivering modern comfort.
