Heat Pump Installation in San Diego, CA.

For a 1920s Craftsman with no existing ductwork, a multi-zone ductless mini-split heat pump system is almost always the right answer. Retrofitting traditional central forced-air into a Craftsman destroys ceiling height, requires soffits that compromise the architectural character, and runs $25,000 to $40,000 for marginal results. A two-zone or three-zone Mitsubishi, Daikin, or LG ductless system handles both cooling and heating, preserves the home's original character, and typically runs $11,000 to $18,000 for a 1,200 to 1,800 square foot bungalow. We coordinate with the City of San Diego Historic Resources Board on any contributing-structure homes that need exterior equipment review.

Ductwork is the question that decides whether your new system actually performs at its rated efficiency. On a 1962 Clairemont tract home, the original attic ductwork is almost certainly leaking 25 to 40 percent of conditioned air into the attic, with insulation degraded and connections separated. We run a duct leakage test (Title 24 requires it on replacement projects), and if leakage exceeds the threshold (15 percent of system airflow) we either seal and re-insulate the existing runs or replace them entirely. Full duct replacement typically adds $4,000 to $9,000 to a project, but it is the only path to actually capturing the energy savings the new equipment is rated for.

Title 24 is California's energy code, and any heat pump replacement in San Diego triggers compliance review. The key requirements: duct leakage testing on most replacements, refrigerant charge verification, proper system sizing per Manual J load calculation, and minimum efficiency ratings (16 SEER2 on central AC, higher on heat pumps). For replacements in existing homes the requirements are scaled back from new construction but still meaningful. We handle all Title 24 documentation and submit the required HERS (Home Energy Rating System) verification through a certified third-party rater. The HERS verification cost ($350 to $600) is included in our project quotes.

Rebate and incentive programs for heat pump installs change year to year and funds run out mid-cycle, so we never quote a guaranteed amount up front. SDG&E, TECH Clean California, and income-qualified programs like HEEHRA each carry their own equipment thresholds (SEER2 and HSPF minimums) and eligibility rules. We confirm exactly what your project qualifies for at quote time and handle all rebate paperwork on qualifying installs, documenting the equipment specifications, efficiency ratings, and installation details the programs require.

Same-day in most cases. Central San Diego dispatch runs from our service area via I-5, I-15, I-805, and the connecting surface streets, typically 25 to 45 minutes from call to truck on site depending on neighborhood and traffic. After-hours emergency calls during summer heat events get priority dispatch 24/7. Diagnostic fee is $89, credited toward any repair you proceed with. For commercial calls in Downtown and Hillcrest, we handle access coordination through building management or HOA contacts.
