Whole-home energy upgrades run $5,000-$100,000 over 1-2 weeks. Federal 25C credits + utility rebates can offset 20-40% of qualifying work. The deepest savings come from sealing air leaks (blower-door identifies them), not from new equipment alone. The process below covers assessment through rebate filing.
We perform a detailed energy assessment of your entire home, analyzing utility bills, inspecting appliances, testing for air leaks, and identifying all opportunities for efficiency improvements.
Outcome:
A complete picture of your home's energy consumption and prioritized upgrade recommendations.
Based on the audit, we create a personalized upgrade roadmap. We prioritize improvements by ROI -from quick wins like LED lighting to major upgrades like window replacements or appliance swaps.
Outcome:
A strategic plan with clear costs, savings projections, and available rebates for each upgrade.
Buildda navigates California's complex rebate landscape for you, including utility programs, state incentives, and federal tax credits. We ensure you capture every available dollar of savings.
Outcome:
Maximum financial incentives secured before work begins.
We upgrade your home to energy-efficient LED lighting throughout, including smart switches and dimmers where beneficial. Outdated fixtures are replaced with modern, efficient alternatives.
Outcome:
Significant lighting energy savings with improved illumination quality.
We install ENERGY STAR appliances and high-efficiency water heaters, including tankless or heat pump options. Old, inefficient units are properly removed and recycled.
Outcome:
Modern, efficient appliances that significantly reduce energy and water consumption.
Our licensed electrical subcontractors upgrade your panel if needed, install whole-home surge protection, and ensure your electrical system is ready for future electrification like EV charging or heat pumps.
Outcome:
A modern electrical infrastructure prepared for today's needs and tomorrow's technology.
We install and configure smart thermostats, energy monitors, and automated controls that help you track and optimize energy usage in real-time.
Outcome:
Intelligent home systems that continuously optimize your energy consumption.
After completing all upgrades, we demonstrate your new systems, provide energy-saving tips, and register all warranties. We're available for follow-up questions and future efficiency improvements.
Outcome:
A more efficient, comfortable home with documented savings and long-term support.

Comprehensive Energy Efficiency Solutions
Whole-home energy upgrades in LA run $5,000-$10,000 for targeted single-system improvements (insulation, attic sealing, single-room HVAC), $14,000-$30,000 for combined system retrofits, and $45,000-$100,000 for deep retrofits with envelope sealing, electrification, and major HVAC. Federal 25C credits + utility rebates can offset 20-40% of qualifying work. Sequencing matters as much as scope: air sealing before insulation, insulation before HVAC sizing, ductwork before equipment. Skip the sequence and money is left on the floor - typically 15-25% of the available rebate stack.
Whole-home energy upgrades run $5,000-$100,000 depending on bundled scope. The deepest savings come from sealing air leaks, not from new equipment. Most California homes built before 2010 have significant air leakage at attic penetrations, can lights, and rim joists. We start with a blower-door test, identify the air-leakage points, then sequence insulation and HVAC work for maximum rebate stacking. Cost variance comes from audit depth (basic walkthrough vs. blower-door + duct-leakage testing), the bundle of upgrades selected (insulation alone vs. insulation + HVAC + windows + air sealing), rebate stacking eligibility (TECH Clean California for heat pumps, federal 25C Energy Efficient Home Improvement Credit for insulation/HVAC, federal 30% Residential Clean Energy Credit for solar + battery), HERS verification on permitted scope (about $400-$800 added), and panel-upgrade requirement when adding a heat pump + induction stove + EV charger to a 100A panel. We sequence the trades under license #1131088 and pull each permit, so the rebate paperwork comes back signed and clean. 2-year workmanship warranty.
