The owner, Sam Mousavi, personally performs in-home consultations and quotes — never a commission salesperson. - Name: Plum HVAC - Owner: Sam Mousavi - Address: 1074 Wentworth St, Mountain View, CA 94043 - Phone: (650) 605-5986 - Email: contact@plumhvac.com - License: CSLB #1087978 - Manufacturer status: Mitsubishi Electric Elite Diamond Contractor - Rating: 5.0 stars on Google - Experience: 14+ years - Hours: Mon–Fri 9AM–5PM · Sat 9AM–3PM · Sun emergency only - Financing: Wisetack, up to $25,000 (soft credit check, interest-free options, decision in seconds) - Tagline: "Comfort That Grows With Your Home" Services offered: Air Conditioning, Heating, Heat Pumps, Ductless Mini Splits, Indoor Air Quality (smart thermostats, ductwork, air filtration), and Heat Pump Water Heaters.

The incentive landscape changed for 2026, and a lot of older online advice is now wrong. Here is where things actually stand: - Federal 25C tax credit: expired December 31, 2025. Plum does not count on it for 2026 projects. - TECH Clean California (single-family) and federal HEEHRA: waitlisted statewide in 2026 with no confirmed reopen date. Plum will not advertise them as available. - Still worth checking: local Community Choice Energy (CCA) and utility programs below, plus SGIP — these may apply depending on your address. - Always available: Wisetack financing (up to $25,000) — the lever you can count on regardless of rebate timing. Verified Bay Area programs Plum tracks for you (funding and amounts change constantly, so each shows a verify-current status rather than a promised dollar figure): Silicon Valley Clean Energy (SVCE) — Community Choice Energy for parts of Santa Clara County (Cupertino, Los Altos, Los Gatos, Milpitas, Mountain View, Saratoga, Sunnyvale and more); Peninsula Clean Energy (PCE) — Community Choice Energy for San Mateo County and part of Santa Clara County; San Jose Clean Energy (SJCE) — electrification incentives for City of San Jose customers; City of Palo Alto Utilities (CPAU) — Electrification Rebate Hub for heat pump HVAC and water heater rebates; Silicon Valley Power — municipal utility rebates for the City of Santa Clara; BayREN Home+ — regional 9-county Bay Area rebates for heat pumps and heat pump water heaters; SGIP — statewide CPUC program for battery storage and qualifying heat pump water heaters. The Rebate Concierge: Plum matches your address to active programs, completes and submits the applications, follows up, and monitors the waitlists so it can file the moment funds reopen. Plum's team (including Natalie) has walked many customers through rebate paperwork such as BayREN. ## Financing URL: https://www.plumhvac.com/financing Plum HVAC offers financing through Wisetack: up to $25,000, with interest-free options if eligible, a soft credit check that won't affect your score, and a decision in seconds. Financing is the lever you can count on regardless of rebate timing. ## Free Second Opinion URL: https://www.plumhvac.com/free-second-opinion Already got an HVAC or heat-pump quote? Get a free second opinion from Sam, the owner of Plum HVAC. Peninsula homeowners routinely collect 4–8 quotes; before you sign, let the owner review yours line by line — honest, apples-to-apples, no pressure. It's genuinely free with nothing to sign, the owner reviews it (not a commission salesperson), and you can use the review to decide even if you don't choose Plum. The five things Plum checks in any quote: is the system right-sized (backed by a load calculation, not a guess); does the scope match the real problem (ductwork, electrical, removal); are panel upgrades genuinely needed or padding the price; are permits handled and warranty terms clear; could any current rebate or financing change your out-of-pocket cost. Plum can review heat pumps, air conditioning, heating/furnaces, ductless mini splits, and heat pump water heaters across the Peninsula and South Bay. ## About Plum HVAC URL: https://www.plumhvac.com/about Comfort built on honesty and craft.
