Why homeowners choose Home Upgrade Specialist.
- 1NEM 3.0 battery-paired sizing — most LA solar installers under-size battery for NEM 3.0 economics. HUS sizes solar + battery as one system to improve payback versus solar-only (payback depends on usage, rate plan, equipment, financing, and utility program rules).
- 2Tesla Certified Premium Installer — required for Powerwall 3 and Tesla Solar Roof. Only LA contractor on this list with HVAC + Solar + Tesla Premium combined.
- 3Files every rebate — federal tax credit (if eligible), SGIP (higher tiers may be available in HFTD, subject to program funding and eligibility), LADWP solar incentive, IRA heat pump credit (if paired with HVAC). Single-trade solar installers typically file 1-2 of these. Incentives are subject to eligibility and current law; Home Upgrade Specialist is not a tax advisor.
- 4Combined-trade pricing — bundled project pricing may improve overall project economics on solar + battery + HVAC + roof projects.
- 5Premium panels at competitive pricing — REC Alpha Pure-R, Qcells Q.TRON, Canadian Solar HiHero. Premium equipment options are compared by production, warranty, price, and homeowner goals.
