Heat Pump Installation from a Licensed Silicon Valley HVAC Contractor
The first conversation is always electrical. A typical 3-ton ducted heat pump (Carrier 38MURA, Trane XR16 Heat Pump, Mitsubishi PUZ-A36NHA) draws 18-24 amps continuous and starts at 60-90 LRA. On a 100-amp service panel — common in Palo Alto homes built before 1985 — adding that load on top of an existing electric range, electric water heater, and EV charger may exceed available capacity per CEC §220 calculations. We do a load calculation against your existing panel before quoting equipment. Often a panel upgrade ($3,500-$6,500 done with our licensed electrical partner) is part of the project. Sometimes a soft-starter (Micro-Air SureStart) on the heat pump compressor reduces inrush enough to stay within existing service. Sometimes a smart panel (SPAN, Lumin) lets you avoid the upgrade by managing concurrent loads. We model all three options.
Equipment selection depends on whether you need cold-climate performance, ducted vs ductless, single-zone vs multi-zone, and which CCA serves your address (some rebates are tier-conditional on equipment HSPF2 rating). For ducted whole-home installs in our climate, the leaders are: Carrier Infinity 38MURA (variable-speed, 22 SEER2 / 11 HSPF2, integrates with Greenspeed indoor unit), Mitsubishi PUZ-A series (cold-climate Hyper-Heat, 100% capacity at 5°F, $14,000-$22,000 installed), Daikin Fit DZ20VC (variable-speed, 20.5 SEER2, R-32 refrigerant, smaller footprint for tight Old Palo Alto side yards), and Trane XV20i Heat Pump (premium variable, 20 SEER2). For ductless mini-split in Eichlers and ADUs, Mitsubishi MXZ-SM multi-zone with MSZ-FH wall units dominates. We carry all of these and have no manufacturer quotas.
TECH Clean California rebate processing is its own workflow. Eligible equipment must be on the TECH-approved list (HSPF2 minimum 8.1 for tier 2, 9.5 for tier 3 on ducted; 9.0 / 10.0 on ductless). The contractor must be TECH-enrolled (we are, contractor ID on file). The installation must be commissioned with refrigerant charge verification per Title 24 and HERS rated. Application must be filed within 12 months of install completion. Rebate amounts range $1,000 (single-zone ductless replacing electric resistance) to $3,000 (whole-home heat pump replacing gas furnace, tier 3 equipment). We file the application, submit the supporting documents (Manual J load calc, HERS report, manufacturer AHRI certificate, paid invoice), and you receive direct deposit usually within 8-14 weeks.
Panel upgrade integration is where most projects get more complex. We coordinate with a licensed C-10 electrical contractor for any service work — the heat pump install itself is C-20 mechanical, but panel upgrades, EV charger circuits, and main breaker work require electrical license. Common patterns in our service area: 100A to 200A upgrade with new meter main combo for older Old Palo Alto, Crescent Park, and Willow Glen homes ($4,500-$6,500); 200A panel addition with subpanel for new heat pump dedicated circuits ($2,800-$4,200); SPAN smart panel installation for concurrent load management ($6,500-$9,500 including app integration). PG&E meter swaps add 4-8 weeks of utility scheduling on top of installation timeline.
Commissioning is the difference between a heat pump that lives 18 years versus 11. We go beyond Title 24 / HERS requirements: refrigerant charge verified by weight (using Yellow Jacket digital scale to ±0.1 oz), subcool measured at design conditions and logged, defrost cycle observed and timed (most demand-defrost units start their first cycle within 90 minutes of heat operation), backup heat lockout temperature set per Manual J calc (typically 28-32°F balance point for Bay Area design), and modulation verified by watching the compressor frequency through the manufacturer's service tool. Every commissioned install gets a written report with all readings and a compressor RLA and HSPF2 calculation at the actual install conditions. That report goes in your customer file for the warranty period.

Common Heat Pump Installation Issues We Resolve
Existing 100-amp panel cannot support new heat pump load
Cause: Service panel sized for original 1970s loads, modern home adds 60-100 amps of new electric loads
Fix: Panel upgrade to 200A ($4,500-$6,500) or smart panel / soft-start solution ($1,800-$9,500)
Customer wants heat pump but ductwork is undersized
Cause: Variable-speed heat pumps need 400 CFM/ton at low static; older ducts often deliver 350 CFM/ton at high static
Fix: Duct rework: return upsize $400-$1,200, supply trunk modification $1,500-$4,000
Outdoor unit placement constrained in tight Eichler atrium or Old Palo Alto side yard
Cause: Modern heat pumps need 12-inch clearance on side, 36-inch front, plus airflow path
Fix: Daikin Fit (smaller footprint) or wall-mount Mitsubishi solutions; sometimes relocate to roof or front yard with screening
Customer expects equivalent gas furnace warm-air feel
Cause: Heat pump supply air is 95-105°F vs gas furnace 130-145°F — feels less warm to the hand even at same room temp
Fix: Education during proposal; supply air temp expectation set in writing; consider auxiliary heat strip for cold-snap days
Replacing gas furnace creates orphaned water heater on shared chimney
Cause: Removing the furnace removes the heat that drives water heater draft up the chimney
Fix: Concurrent water heater replacement with power-vent or heat pump tankless; or chimney liner downsize per CMC §802

Local Context: Heat Pump Installation in Silicon Valley
The Bay Area is the most aggressive heat pump electrification market in the country measured by per-capita installs and stacked incentive value. The City of Palo Alto operates its own electric utility (CPAU) with separate rebate programs from PG&E. Surrounding cities are split between Silicon Valley Clean Energy (SVCE — Sunnyvale, Mountain View, Cupertino, Saratoga, Los Altos) and Peninsula Clean Energy (PCE — San Mateo County including Menlo Park, Atherton, Redwood City). Each CCA has its own heat pump rebate amounts and equipment qualification criteria. Many city reach codes (Berkeley, Mountain View, San Mateo) now require all-electric in new construction, and remodels triggering Title 24 thresholds are increasingly defaulting to heat pump. Mid-century Eichlers in Greenmeadow and Fairmeadow are common conversion candidates because their original radiant slab boilers are aging out and ductless mini-split + air-source heat pump for slab supplement is a clean retrofit. The peninsula also has heavy solar PV adoption under NEM 2.0 and NEM 3.0 — adding a heat pump pairs cleanly with an existing solar array, often turning a marginal energy home into net-positive.

Heat Pump Installation FAQ
How much do all the rebates and credits actually total?
Stacked typical Bay Area heat pump conversion: federal IRA 25C tax credit ($2,000), TECH Clean California rebate ($1,000-$3,000 depending on tier and replacement type), PG&E rebate ($300-$1,000), Silicon Valley Clean Energy electrification rebate ($1,500-$3,000) OR Peninsula Clean Energy rebate ($2,500-$5,000). Total commonly $5,800-$11,000 in incentives on an $18,000-$22,000 installed system. We file every applicable rebate. The CCA rebates are address-specific so we verify eligibility before proposal.
Do I need a panel upgrade for a heat pump?
Maybe. A 100A service is often tight; a 125A service is usually OK; a 200A service is comfortably oversized. We do a CEC §220 load calculation including heat pump LRA, existing loads, and any near-term EV / induction range plans. Solutions if undersized: full panel upgrade ($4,500-$6,500), heat pump soft-start to reduce inrush ($350-$650 part installed), or smart panel like SPAN to manage concurrent loads ($6,500-$9,500 with full electrical integration).
Will a heat pump actually keep my Bay Area home warm in winter?
Yes if sized correctly. Bay Area design temperature is 30-35°F overnight; cold-climate heat pumps (Mitsubishi Hyper-Heat MXZ-SM48NAMHZ, Daikin Aurora RZQ24TBVJU9, Carrier Infinity Greenspeed) maintain 100% rated capacity to 5°F — well below any temperature you will see on the peninsula. Non-cold-climate heat pumps lose capacity below 25-30°F and rely on backup electric heat strips for the coldest 20-40 nights per year. We size to design temp + safety margin and verify with manufacturer expanded performance tables.
How is a heat pump different from gas furnace heat to live with?
Two adjustments. First: supply air temperature is 95-105°F instead of 130-145°F. The air feels less warm to your hand at the register, even though room temperature is identical. Second: longer run times. A modulating heat pump runs 60-90% of the hour in cold weather; a gas furnace runs 15-25% of the hour and short-cycles between firings. Most homeowners adapt within 2 weeks and report better even-temperature comfort. We set written expectations during the proposal so the first cold morning is not a surprise.
Can I get a heat pump that also acts as my AC?
Yes — that is how heat pumps work by definition. A single outdoor unit and indoor air handler provide both heating in winter and cooling in summer. You replace both your old furnace and your old AC with one system. If you currently have neither (heat-only home in Crescent Park or Old Palo Alto), the heat pump installation gives you central AC for the first time, often as part of the same project at no incremental equipment cost.
Are you a TECH Clean California approved contractor?
Yes, enrolled since 2022. Our TECH contractor ID is on file with the program. We have processed more than 380 heat pump rebate applications successfully. The TECH program requires specific commissioning steps (refrigerant charge verification, HERS rating) which we perform on every install and document on the application. We have never had a TECH application denied for documentation reasons.
How long does the whole project take?
Quote to signed contract: 5-10 days. Permit pulling: 5-10 business days. Installation: 2-3 days on-site. HERS verification: 1-3 weeks after install. Building inspection: 1-2 weeks after install. Permit close-out: 4-8 weeks total. Rebate funds direct deposit: 8-14 weeks after final inspection. The system is fully operational on day 3; the paperwork and rebate cycle continues for about 3 months in the background.
What if my home is on the SVCE GreenStart or PCE ECO100 plan?
Those CCA service tiers are 100% renewable electricity sourcing. Running a heat pump on GreenStart or ECO100 means your heating is essentially zero-carbon — a major win over gas. PCE has historically offered higher heat pump rebates ($2,500-$5,000) than SVCE ($1,500-$3,000) and we verify which CCA serves your address (it depends on city, not just county) and apply the right rebate.
