Whole-House Energy Audits
Our comprehensive energy audits use thermal imaging, blower door tests, and combustion safety diagnostics to identify hidden inefficiencies. We analyze heat flow, air leakage, and system interactions to create customized upgrade plans. This scientific approach ensures targeted improvements that enhance comfort while reducing energy consumption by up to 30%.
Air-Sealing Services
We eliminate drafts by sealing gaps in windows, doors, and structural joints using high-performance materials. Our process includes pre- and post-sealing pressure testing to verify effectiveness. This reduces energy loss, prevents moisture intrusion, and improves indoor air quality by blocking outdoor pollutants from entering living spaces.
Insulation Upgrades
We install high-R-value insulation in attics, walls, and crawlspaces to optimize thermal performance. Our team selects materials based on climate needs and existing structure conditions. Proper insulation maintains consistent temperatures, reduces HVAC workload, and lowers utility bills while meeting California's strict energy code requirements.
HVAC System Optimization
We evaluate and upgrade heating, ventilation, and air conditioning systems for maximum efficiency. Services include duct sealing, equipment replacement, and smart thermostat installation. Our approach ensures proper system sizing, balanced airflow distribution, and improved indoor air quality through advanced filtration solutions.
