Who connects the heat pump, caps the gas, and closes the permit?

Find the gaps between electrical and appliance quotes

A Reddit homeowner arranging a heat pump asked whether electrical work normally belongs to the HVAC contractor or a separate electrician. The answer varies by contract, which is precisely why it should be written down. A home electrification project can involve equipment selection, electrical supply, plumbing, gas work, condensate, controls, finish repairs, and inspections. A quote covering one trade should not be assumed to include the entire conversion.

Assign work to the appropriate licensed contractor

CSLB's heat-pump guidance distinguishes the trades: C-20 or C-36 covers heat pump water heaters, while C-20 covers HVAC heat pumps. C-10 covers electrical work such as a necessary panel upgrade; that classification alone does not authorize contracting for the heat pump appliance installation. A general building contractor's permitted role also depends on the contract scope and subcontracting rules. Verify the selected providers and their classifications rather than assuming one electrical quote covers every trade.

Assign equipment installation, final electrical connection, condensate, controls and any gas piping alteration explicitly. Ask the local permit office which permits and inspections the combined scope requires and identify who obtains each one. Stopping utility gas service is a separate task from the contractor's work on customer piping; include both only when they are actually part of the project.

CSLB's C-36 Plumbing classification includes gas appliances, flues and connections, as well as gas piping from the property owner's side of the utility meter. Assign capping an abandoned appliance connection to a contractor licensed for that work and confirm any required local permit and inspection. This is not a claim that only C-36 may perform every gas-related task. Utility-side meter or service work remains a separate utility responsibility.

Illustrative scenario: each quote excludes a different handoff

Illustrative scenario: an HVAC crew arrives to install a heat pump, but its quote excludes the branch circuit. The electrician priced a circuit to a different outdoor-unit location, while no one included removal of obsolete equipment or finish repair. Each quote may accurately describe its own scope. The project is still incomplete because the interfaces were never reconciled. Resolving them before mobilization is usually simpler than negotiating change orders while the home lacks heating.

Name the owner of every installation task

Prepare a responsibility table for equipment procurement, electrical circuits, disconnects, control wiring, plumbing or condensate work, gas decommissioning where applicable, demolition, restoration, permit submissions, and inspections. Mark work as included, excluded, or unresolved with a named party. Avoid vague phrases such as by others without identifying who those others are and when their work must be ready.

Coordinate one model and location schedule

Coordinate changes through one equipment and location schedule. A revised appliance model may affect electrical requirements, space, drainage, noise considerations, and incentive eligibility. The person authorizing the substitution should verify all relevant interfaces. Likewise, a moved electrical panel can affect another trade's route. Keep a short change log so the final installation does not combine incompatible versions of otherwise reasonable plans.

Check operation and permit completion separately

Before final acceptance, check operational completion and paperwork completion separately. Confirm the appliance works in intended modes, the electrical work is identified, required inspections are closed, and the owner has the relevant manuals and support contacts. Do not label a conversion complete because the appliance turns on once. The finished result includes a coherent installation, clear responsibilities, and records that make future maintenance possible.

Include California energy-code verification in the closeout plan

For work governed by the 2025 Energy Code, effective January 1, 2026, California's field-verification program is the Energy Code Compliance program, or ECC, formerly HERS I. A project remains subject to the code version that was effective when it was permitted. The applicable equipment and alteration determine which certificates and tests are required; do not assume every replacement needs the same test list.

Name the party responsible for compliance documents, any required registered certificates, rater coordination and correction of failed verification. Obtain the required closeout evidence before treating the permit as complete. A functioning heat pump and a completed electrical circuit do not establish that HVAC verification or administrative closeout has occurred.

Define completion at the interfaces, not only inside each trade

Define the electrical endpoint precisely: a finished disconnect is different from final appliance connection and commissioning. At the joint handoff, reconcile each trade’s completion record with the permit and energy-code requirements. Give the owner operating guidance and the appropriate support contacts, plus a coordinator for faults that cross trade boundaries.
