Why homeowners choose Home Upgrade Specialist.

Three reasons HUS can be a strong fit for multi-trade Los Angeles home upgrades:

• 1Multi-trade coordination — HUS can coordinate HVAC, solar, battery, roofing and EV charger planning under one project team, which matters when a homeowner is electrifying the house rather than replacing only one piece of equipment.
• 2Tesla Certified Premium Installer — Useful when a homeowner is comparing HVAC alongside Powerwall, Tesla Solar Roof, solar panels or EV charging instead of treating the HVAC system as an isolated upgrade.
• 3Rebate and incentive review — HUS helps homeowners review available heat pump, utility, financing and electrification options where applicable. Rebate and savings amounts vary by home, equipment, utility, funding availability and eligibility on a typical heat pump install.

Quick contractor checklist before you sign.

• ✓Verify the contractor license, classification and insurance before work starts.
• ✓Ask for a written scope that lists equipment model numbers, permits, HERS testing, ductwork, thermostat, disposal and warranty registration.
• ✓Confirm whether rebate guidance is included and whether any rebate amount is only an estimate subject to program approval.
• ✓For heat pumps, ask how the system will be sized and whether ducts, electrical capacity or panel upgrades need review.
• ✓If you plan solar, Powerwall, roofing or EV charging later, ask whether the HVAC choice supports the broader electrification plan.

Three-step estimate path.

1. 1Send the basics: home size, current system age, hot or cold rooms, utility provider, and whether you are considering heat pump, solar, Powerwall, roofing or EV charging later.
2. 2Review the written scope: model numbers, efficiency ratings, permit handling, HERS testing if required, duct or electrical work, warranty terms and payment schedule.
3. 3Confirm the decision: compare comfort goals, total installed cost, financing, possible incentives and who is responsible for documentation before approving work.
