Opening script to send contractors
Hi, I'm in Oakland, CA and planning a project that includes Heat Pump HVAC. I am looking for a quote that includes: 1. Heat Pump HVAC Please tell me: - Will you perform a formal load calculation (Manual J for HVAC, Article 220 for electrical)? - Are you familiar with Oakland permits and any local rebate programs? - Can you give line-item pricing and separate confirmed incentives from assumed incentives? - Who handles permits, inspections, and rebate paperwork?
Technical basics in plain English
Panel size: 100A, 125A, 150A, 200A
Your electrical panel is the main entry point for electricity into your house. The 'A' means amps. More amps means more total electrical capacity. 100A is older and may not support adding heat pump + water heater + EV charger together without an upgrade or smart load management. 125A/150A is middle ground; could work with efficient equipment and a real load calculation. 200A is usually the cleanest path, but not guaranteed.
Ask: What is my panel size, and can you show me the load calculation that proves this setup is safe?
Load calculation
A load calculation is not the same as guessing. It is a code-based calculation that estimates whether your panel and service can safely carry all major electrical loads. A qualified electrician or contractor should be able to explain whether you need a panel upgrade, a service upgrade, or smart load management instead.
Ask: Are you doing a formal electrical load calculation, or just eyeballing the panel?
120V vs 240V
Normal outlets are usually 120V. Large appliances often use 240V, like a dryer or EV charger. Many heat pump HVAC systems, EV chargers, and some water heaters need 240V.
Ask: Which parts of this project require 240V?
Manual J load calculation (HVAC)
Manual J is the standard HVAC sizing calculation. It accounts for home size, insulation, windows, orientation, and ductwork. A good HVAC contractor performs Manual J before sizing the equipment; bad contractors just match the existing furnace tonnage.
Ask: Will you perform a Manual J load calculation before sizing the equipment?
Specific questions to ask
Questions for HVAC contractors
| Question | Good response | Bad response |
|---|---|---|
| Will you perform a Manual J load calculation before sizing the heat pump? | Yes. We calculate heating and cooling load based on home size, insulation, windows, orientation, ductwork, and infiltration. | We just replace the existing furnace with the same tonnage system. |
| Will you inspect ducts before specifying the heat pump? | Yes. We inspect duct size, leakage rate, return air paths, and airflow because heat pumps need good airflow at moderate static pressure. | Ducts are always fine; no need to check. |
| How do you decide system size in tons or BTU? | We explain tons and BTU using Manual J inputs, not just square footage. | We use 1 ton per 500 square feet as a rule of thumb. |
| What refrigerant does the system use, and is it compliant with current EPA rules? | We specify the refrigerant (R-454B or R-32 for new systems after the EPA A2L transition) and confirm it meets current code. | Refrigerant does not affect homeowners. |
| Are you a TECH Clean California enrolled contractor, and is the program currently funded for heat pump HVAC? | We verify current TECH Clean California program status (single-family Phase I has been fully reserved since November 2025) and explain whether it applies before signing. | TECH always pays out; assume the rebate is yours. |
| Does my household income make us eligible for HEEHRA, and what does that involve? | We confirm income eligibility (below 80 percent AMI or 80 to 150 percent AMI), explain pre-approval is required, and verify program status (Phase I single-family is currently fully reserved per CEC as of 2026-02-24). | HEEHRA covers everyone; you qualify automatically. |
| How does BAAQMD Rule 9-4 affect a like-for-like natural-gas furnace replacement at this Oakland address? | BAAQMD Rule 9-4 (amended March 15, 2023) sets a zero-NOx standard for new residential furnaces sold or installed in the Bay Area effective January 1, 2029. We confirm the effective date against your appliance class and timing, document the citation in writing, and walk through whether a heat-pump path avoids a regulatory dead-end before the cutover. We do not assume the rule has already kicked in for furnaces; we read the actual schedule. | BAAQMD rules don't affect Oakland homeowners. |
| Does BAAQMD Rule 9-6 affect a gas water heater I'm leaving in place during the HVAC replacement? | BAAQMD Rule 9-6 sets a zero-NOx standard for new residential and small commercial water heaters under 75,000 BTU/hr effective January 1, 2027. The rule applies to new units sold or installed; it does not retroactively force you to remove a working gas water heater. We document the effective date and let you decide whether to bundle the HPWH switch with the HP HVAC project given the upcoming cutover. We do not pressure-sell the bundle on a rule that has not yet taken effect. | Rule 9-6 forces you to remove your gas water heater immediately. |
| How do you size differently for Oakland Hills vs flatland Oakland given the East Bay summer heat? | Oakland Hills (Montclair, Skyline, Joaquin Miller) summer design temperatures run 5-10 degrees F warmer than flatland Oakland (Lake Merritt, West Oakland, Fruitvale) and materially warmer than coastal SF. We use ACCA Manual J 8th Edition with the ASHRAE 99 percent heating design value (around 37-40 degrees F for the East Bay) and the cooling-load demand for the actual neighborhood. We do not use SF coastal sizing for an Oakland Hills home, and we do not use East County inland sizing for a Berkeley-border flatland home. We share the Manual J output. | We use a 1-ton-per-500-square-feet rule of thumb. |
| We're in an older Craftsman or 1920s bungalow. How does that change your Manual J assumptions and equipment choice? | Older East Bay Craftsman and bungalow homes typically have minimal wall insulation, single-pane original wood-sash windows or first-generation replacements, and sometimes unconditioned crawl spaces and attics. We adjust the envelope inputs in Manual J accordingly rather than using a 2025 build assumption. We often recommend an envelope tune (attic insulation, ducting where feasible, sealed crawl space) alongside the heat-pump install so we are not oversizing to overcome an avoidable leak. We share both the unimproved and improved Manual J runs. | Older homes need more tonnage; we just oversize. |
| Given Oakland's climate, is dual-fuel (heat pump plus gas backup) worth it or should we go all-electric? | East Bay heating design temperatures rarely fall below the mid-30s F. A modern inverter-driven cold-climate heat pump holds rated capacity well within Oakland's range; a gas backup is usually unnecessary in this climate. The choice is driven by whether you want to retain a working gas furnace for resilience during PG&E outages, what BAAQMD Rule 9-4 timing means for your replacement window, and whether you have an oversized cooling load. We model both options and let you decide. | Always keep a gas backup; heat pumps fail in the cold. |
| Which refrigerant are you specifying and what does A2L safety mean for an Oakland install? | Effective January 1, 2025, AIM Act-driven federal rules require new residential heat pumps to use R-454B or R-32 (both A2L mildly-flammable refrigerants) rather than R-410A. Manufacturers have shifted accordingly. A2L refrigerants are safe when installed per manufacturer instructions; indoor unit charge limits, leak-detection sensor requirements on ducted systems, and equipment-room ventilation rules apply. We document the refrigerant, charge, and any required leak-detection sensor in the proposal and confirm Oakland P&B will sign off. | R-410A is fine; we'll just use that. |
| Where will the outdoor unit go and does Oakland have a noise ordinance to worry about? | Oakland Municipal Code Chapter 8.18 sets noise limits at residential property lines, typically 60 dBA daytime and 45 dBA nighttime. A typical modern inverter heat pump outdoor unit runs 55-65 dBA at 3 feet; with setback distance from the property line, sound-isolation pads, and orientation away from neighbor bedrooms it generally meets Oakland's limits. We document the unit's sound rating, the proposed setback, and any sound-isolation hardware in the proposal. We do not place the unit somewhere we have not verified meets the ordinance. | Just put it anywhere; Oakland doesn't enforce noise. |
| Beyond Manual J, do you run Manual S and Manual D and do you share the outputs? | Manual J sets the load; Manual S selects the right equipment to meet that load (capacity, modulation range, defrost behavior); Manual D sizes the ducts to deliver the airflow without static-pressure penalties. Many East Bay retrofits inherit undersized return ducts that limit airflow no matter the equipment. We run all three and share the outputs, including any required duct modifications as a line item. | Manual J is enough; the other two are overkill. |
| What does commissioning look like at the end of the job and do you give me the report? | At commissioning we verify static pressure with a manometer (target around 0.5 in.w.c. on most residential ducted systems), set airflow via measurement at each register, verify charge by superheat or subcooling per manufacturer spec for R-454B or R-32, log compressor amp draw, and confirm thermostat communication. We provide a signed commissioning sheet with the measured values. Without commissioning a 'right-sized' system can still underperform 20-30 percent. | Commissioning is just an upsell; modern equipment self-tunes. |
| What warranty terms apply and does Oakland's proximity to the Bay affect equipment lifespan? | Typical residential warranties on R-454B / R-32 heat pumps run 10 years parts and 1-2 years labor when registered with the manufacturer within 60 days; some platforms (Mitsubishi Diamond Contractor, Daikin Comfort Pro) extend labor to 10-12 years when installed by certified contractors. Outdoor units within 1-2 miles of the Bay shoreline (West Oakland, Jack London) see salt-air exposure; we either specify the manufacturer coastal package (corrosion-resistant coil and fins) or document why standard equipment is appropriate. We register the warranty for you and share the confirmation. | Warranty is automatic; the salesperson handles it. |
| If we go all-electric, is there a backup-heat strategy or is the heat pump on its own? | Modern cold-climate inverter heat pumps hold rated capacity to about 5 degrees F or lower, which is far below any Oakland design condition. Auxiliary heat (electric strip) is typically not needed for Oakland's climate; we leave it out of the install unless Manual J shows a specific deficit at design conditions. Strip heat is expensive to run and adds peak demand. If you are concerned about resilience during a deep cold snap, a small ductless head in the main living space provides redundancy without strip heat. | Always add strip heat; you can never have too much backup. |
| We are in the Oakland Hills WUI zone. Does that affect outdoor-unit siting or materials? | Oakland Hills addresses in the CAL FIRE Very High Fire Hazard Severity Zone (Montclair, Skyline, Joaquin Miller, Piedmont border) fall under California Residential Code Chapter R337 for wildfire-resistant construction. Outdoor equipment siting against eave overhangs, near combustible landscaping, or in zone-0 (the first 5 feet of defensible space) needs ignition-resistant placement and sometimes spark-arrestor screening on intake louvers. We document the FHSZ designation against the address, site the unit per R337 setbacks, and use ignition-resistant materials where required. | WUI rules don't apply to mechanical equipment. |
Questions for electricians
| Question | Good response | Bad response |
|---|---|---|
| What is my panel size and service size, and is it adequate for adding a heat pump? | We inspect the panel labels and main breaker on site, explain whether 100A, 125A, 150A, or 200A is adequate, and verify the service drop matches the panel. | We guess from a photo only; no on-site inspection. |
| Can we avoid a service upgrade by using smart load management? | Possibly. We will perform a formal Article 220 load calculation, propose smart load management for HVAC + EV + water heater coordination, and explain the tradeoff vs upgrading. | You always need 200A; no calculation needed. |
| Will the heat pump need a new dedicated circuit, and what breaker size? | Yes, the outdoor unit and air handler each typically need dedicated circuits at the breaker sizes the manufacturer specifies (often 30-50A for outdoor, 15-30A for indoor). | Any spare breaker will work. |
| We've heard knob-and-tube wiring is common in older East Bay homes. Will that block the heat-pump install? | Knob-and-tube wiring is widespread in Craftsman, bungalow, and older West Oakland and Oakland Hills homes. Oakland Planning and Building generally treats active knob-and-tube as an existing condition that does not by itself block a new dedicated circuit for a heat pump; however, if the new circuit ties into a knob-and-tube branch or the panel needs upgrade, rewiring is often required. Some homeowner insurance carriers also require rewiring. We assess at the site visit, list any required rewiring scope as a line item, and do not bury it in labor. | Knob-and-tube is fine; we just splice the new circuit in. |
General questions for every contractor
| Question | Good response | Bad response |
|---|---|---|
| Can you separate confirmed incentives from assumed incentives in the quote? | Yes. We mark each incentive as confirmed (with program ID and current reservation status) versus assumed (subject to verification before contract). | All listed incentives are yours. |
| Does the federal Section 25C tax credit apply to my installation? | Section 25C expired December 31, 2025 under the One Big Beautiful Bill Act (Public Law 119-21). Installations completed in 2026 or later do not qualify for §25C. | You'll get the federal credit on your taxes. |
| Are BayREN Home+ rebates available for this installation? | BayREN Home+ may apply for Bay Area homeowners; we verify the program is currently funded and that the equipment qualifies before submitting. | BayREN always pays out automatically. |
| What is the equipment and labor warranty, and what voids it? | We provide the manufacturer warranty (typically 10 years parts when registered) plus our labor warranty (1-2 years standard); we explain what voids coverage including improper electrical, missing filters, and skipped annual service. | The warranty covers everything forever. |
| What is the best next step before signing a contract? | Schedule a site visit and Manual J load calculation, get a written quote with line-item pricing, verify all incentive reservation requirements, and confirm permit handling. | Sign today to lock in pricing before incentives expire. |
| Who pulls the mechanical and electrical permits with City of Oakland Planning and Building and how is that visible to me? | We pull the mechanical permit through the City of Oakland Planning and Building Department (oaklandca.gov/departments/planning-building, online via the Tyler EnerGov self-service portal) under our contractor license, plus a separate electrical permit if the new circuit requires it. You receive copies of both permit applications, the permit numbers, the inspection schedule, and the final card sign-offs. Permit fees are itemized separately in the proposal, not bundled into labor. Oakland review timelines run longer than SJ or SF; we set expectations honestly. | Most heat-pump swaps in Oakland don't need a permit. |
| How does Ava Community Energy's Bright Choice default vs Renewable 100 opt-up affect the carbon-accounting story of switching to a heat pump? | Ava Community Energy (the CCA formerly known as East Bay Community Energy, rebranded October 2023) is the default electric-supply provider in Oakland. The default Bright Choice product is around 62 percent eligible renewable per Ava's published 2024 figure and is priced about 0.5 percent below PG&E generation rates; Renewable 100 is 100 percent RPS-eligible renewable for roughly an extra 1.75 cents per kWh above PG&E. Switching from a gas furnace to an electric heat pump moves combustion load onto your Ava supply, so the carbon outcome depends on which product you are on. We do not promise a specific carbon number; we explain the product tiers and let you decide on avaenergy.org. The supplier-side rate (Ava) replaces PG&E's generation portion; the delivery portion still goes to PG&E. | Ava makes heat pumps automatically zero-carbon. |
| What rebates does BayREN Home+ pay for a heat-pump HVAC swap in Oakland? | Oakland is in Alameda County and inside the nine-county BayREN service area. BayREN Home+ pays a rebate of around $1,000 for a qualifying heat-pump HVAC installation; we confirm the current amount on bayren.org before quoting. Reservation order matters; we submit the application before equipment delivery and document the reservation number in the proposal. We do not list a BayREN line item until the reservation is confirmed. | BayREN pays $5,000 for any heat pump. |
| What about TECH Clean California and HEEHRA for a heat pump in Oakland? | TECH Clean California was reported fully reserved as of November 14, 2025; HEEHRA was reported fully reserved statewide as of February 24, 2026. Both are currently waitlisted; new reservations may or may not move during the project window. We list the program status honestly as waitlisted in the proposal and do not include the dollar amount as a confirmed deduction. We monitor selfgenca.com and the program portals and update you if anything reopens. | TECH and HEEHRA always pay out; you qualify. |
| After we install the heat pump, which PG&E rate plan are you recommending: E-ELEC, E-TOU-C, EV2-A, or something else? | We compare three scenarios using your prior 12 months of usage: E-ELEC (whole-home rate optimized for electrified loads with HP HVAC plus HPWH plus EV), E-TOU-C as the baseline, and EV2-A only if EV ownership is part of the picture. The March 2026 Base Services Charge ($24 per month) applies on the relevant plans; we factor it in. We share a spreadsheet showing modeled monthly cost on each plan. The right plan depends on which other electrified loads you have or are planning. | E-ELEC is always cheapest after a heat pump. |
| We are in the Oakland Hills and PG&E PSPS events happen regularly. How does that affect the heat-pump decision? | PG&E PSPS events in the Oakland Hills can run 8-24 hours, occasionally longer in extreme weather. A heat pump itself is no more or less PSPS-resilient than the gas furnace it replaces; both depend on power for the blower and controls. The real question is whether you want a battery in scope for backup. If yes, we size the battery to cover the heat pump's compressor surge (typically 6-9 kW continuous + LRA inrush for a 3-4 ton unit), critical lighting, refrigerator, Wi-Fi, and any medical equipment for the design outage. The choice influences battery sizing more than heat-pump selection. | PSPS just means buy a heat pump; it solves outages. |
| Should I expect the federal 25C credit on this heat pump? | The federal Energy Efficient Home Improvement Credit (Section 25C) expired December 31, 2025 under the One Big Beautiful Bill Act (OBBBA, PL 119-21). Installations placed in service in 2026 or later are not eligible. We list the credit as expired in the proposal and do not deduct it from your project cost. If you placed the system in service before December 31, 2025 the credit may apply; we document the placed-in-service date. | 25C still applies; we deduct it from your quote. |

| How does BAAQMD Rule 9-4 affect a like-for-like natural-gas furnace replacement at this Oakland address? | BAAQMD Rule 9-4 (amended March 15, 2023) sets a zero-NOx standard for new residential furnaces sold or installed in the Bay Area effective January 1, 2029. We confirm the effective date against your appliance class and timing, document the citation in writing, and walk through whether a heat-pump path avoids a regulatory dead-end before the cutover. We do not assume the rule has already kicked in for furnaces; we read the actual schedule. | We confirm the BAAQMD Rule 9-4 effective date against your timing; a heat-pump path sidesteps the future cutover. | BAAQMD rules don't affect Oakland homeowners. |
| Does BAAQMD Rule 9-6 affect a gas water heater I'm leaving in place during the HVAC replacement? | BAAQMD Rule 9-6 sets a zero-NOx standard for new residential and small commercial water heaters under 75,000 BTU/hr effective January 1, 2027. The rule applies to new units sold or installed; it does not retroactively force you to remove a working gas water heater. We document the effective date and let you decide whether to bundle the HPWH switch with the HP HVAC project given the upcoming cutover. We do not pressure-sell the bundle on a rule that has not yet taken effect. | Rule 9-6 applies to new units starting January 1, 2027; we share the citation and let you decide on bundling. | Rule 9-6 forces you to remove your gas water heater immediately. |

| Given Oakland's climate, is dual-fuel (heat pump plus gas backup) worth it or should we go all-electric? | East Bay heating design temperatures rarely fall below the mid-30s F. A modern inverter-driven cold-climate heat pump holds rated capacity well within Oakland's range; a gas backup is usually unnecessary in this climate. The choice is driven by whether you want to retain a working gas furnace for resilience during PG&E outages, what BAAQMD Rule 9-4 timing means for your replacement window, and whether you have an oversized cooling load. We model both options and let you decide. | All-electric is usually fine in Oakland's climate; dual-fuel is more about resilience preference than performance need. | Always keep a gas backup; heat pumps fail in the cold. |
| Which refrigerant are you specifying and what does A2L safety mean for an Oakland install? | Effective January 1, 2025, AIM Act-driven federal rules require new residential heat pumps to use R-454B or R-32 (both A2L mildly-flammable refrigerants) rather than R-410A. Manufacturers have shifted accordingly. A2L refrigerants are safe when installed per manufacturer instructions; indoor unit charge limits, leak-detection sensor requirements on ducted systems, and equipment-room ventilation rules apply. We document the refrigerant, charge, and any required leak-detection sensor in the proposal and confirm Oakland P&B will sign off. | We specify R-454B or R-32 per current code; the refrigerant, charge, and any leak-detection requirements are documented in the proposal. | R-410A is fine; we'll just use that. |
| Where will the outdoor unit go and does Oakland have a noise ordinance to worry about? | Oakland Municipal Code Chapter 8.18 sets noise limits at residential property lines, typically 60 dBA daytime and 45 dBA nighttime. A typical modern inverter heat pump outdoor unit runs 55-65 dBA at 3 feet; with setback distance from the property line, sound-isolation pads, and orientation away from neighbor bedrooms it generally meets Oakland's limits. We document the unit's sound rating, the proposed setback, and any sound-isolation hardware in the proposal. We do not place the unit somewhere we have not verified meets the ordinance. | We site the outdoor unit for the Oakland noise ordinance setback and document the dBA measurement in the proposal. | Just put it anywhere; Oakland doesn't enforce noise. |
| We are in the Oakland Hills and PG&E PSPS events happen regularly. How does that affect the heat-pump decision? | PG&E PSPS events in the Oakland Hills can run 8-24 hours, occasionally longer in extreme weather. A heat pump itself is no more or less PSPS-resilient than the gas furnace it replaces; both depend on power for the blower and controls. The real question is whether you want a battery in scope for backup. If yes, we size the battery to cover the heat pump's compressor surge (typically 6-9 kW continuous + LRA inrush for a 3-4 ton unit), critical lighting, refrigerator, Wi-Fi, and any medical equipment for the design outage. The choice influences battery sizing more than heat-pump selection. | Heat pumps are PSPS-neutral; if outage resilience matters, the battery sizing exercise drives the decision more than the heat-pump model. | PSPS just means buy a heat pump; it solves outages. |
| Beyond Manual J, do you run Manual S and Manual D and do you share the outputs? | Manual J sets the load; Manual S selects the right equipment to meet that load (capacity, modulation range, defrost behavior); Manual D sizes the ducts to deliver the airflow without static-pressure penalties. Many East Bay retrofits inherit undersized return ducts that limit airflow no matter the equipment. We run all three and share the outputs, including any required duct modifications as a line item. | Manual S and D drive equipment selection and duct sizing; we share the outputs. | Manual J is enough; the other two are overkill. |
| Should I expect the federal 25C credit on this heat pump? | The federal Energy Efficient Home Improvement Credit (Section 25C) expired December 31, 2025 under the One Big Beautiful Bill Act (OBBBA, PL 119-21). Installations placed in service in 2026 or later are not eligible. We list the credit as expired in the proposal and do not deduct it from your project cost. If you placed the system in service before December 31, 2025 the credit may apply; we document the placed-in-service date. | 25C expired on December 31, 2025 under OBBBA; we do not deduct it for 2026 installs. | 25C still applies; we deduct it from your quote. |
| What does commissioning look like at the end of the job and do you give me the report? | At commissioning we verify static pressure with a manometer (target around 0.5 in.w.c. on most residential ducted systems), set airflow via measurement at each register, verify charge by superheat or subcooling per manufacturer spec for R-454B or R-32, log compressor amp draw, and confirm thermostat communication. We provide a signed commissioning sheet with the measured values. Without commissioning a 'right-sized' system can still underperform 20-30 percent. | We commission and share the signed sheet; airflow, charge, and static pressure are measured. | Commissioning is just an upsell; modern equipment self-tunes. |
| What warranty terms apply and does Oakland's proximity to the Bay affect equipment lifespan? | Typical residential warranties on R-454B / R-32 heat pumps run 10 years parts and 1-2 years labor when registered with the manufacturer within 60 days; some platforms (Mitsubishi Diamond Contractor, Daikin Comfort Pro) extend labor to 10-12 years when installed by certified contractors. Outdoor units within 1-2 miles of the Bay shoreline (West Oakland, Jack London) see salt-air exposure; we either specify the manufacturer coastal package (corrosion-resistant coil and fins) or document why standard equipment is appropriate. We register the warranty for you and share the confirmation. | Warranty terms are listed in the proposal; we register on your behalf and share confirmation. Coastal package applies for Bay-adjacent addresses. | Warranty is automatic; the salesperson handles it. |
| If we go all-electric, is there a backup-heat strategy or is the heat pump on its own? | Modern cold-climate inverter heat pumps hold rated capacity to about 5 degrees F or lower, which is far below any Oakland design condition. Auxiliary heat (electric strip) is typically not needed for Oakland's climate; we leave it out of the install unless Manual J shows a specific deficit at design conditions. Strip heat is expensive to run and adds peak demand. If you are concerned about resilience during a deep cold snap, a small ductless head in the main living space provides redundancy without strip heat. | Strip heat is usually unnecessary in Oakland; we omit it unless Manual J shows a specific gap. | Always add strip heat; you can never have too much backup. |
| We are in the Oakland Hills WUI zone. Does that affect outdoor-unit siting or materials? | Oakland Hills addresses in the CAL FIRE Very High Fire Hazard Severity Zone (Montclair, Skyline, Joaquin Miller, Piedmont border) fall under California Residential Code Chapter R337 for wildfire-resistant construction. Outdoor equipment siting against eave overhangs, near combustible landscaping, or in zone-0 (the first 5 feet of defensible space) needs ignition-resistant placement and sometimes spark-arrestor screening on intake louvers. We document the FHSZ designation against the address, site the unit per R337 setbacks, and use ignition-resistant materials where required. | We verify the FHSZ designation against the address and site the outdoor unit per CRC R337 for Oakland Hills installs. | WUI rules don't apply to mechanical equipment. |
