Our Work



Benefits
Smart ventilation for mountain air quality
We engineer exhaust fan systems tailored to Altadena’s mountain environment and fire-season needs. We specify corrosion-resistant dampers and louvers, oversized ductwork to minimize noise, low-friction materials to reduce runtime and energy use, and humidity-sensing controls. For kitchens, we design range hood wiring for modern 240V models with dedicated circuits. For fire-rebuilt homes, we emphasize ERV/HRV systems with makeup air provisions and MERV filters to remove wildfire smoke and ash while recovering heating/cooling efficiency. We integrate exhaust wiring into backup generator plans and smart-home systems so ventilation works efficiently with all home systems.
Code-compliant and fire-resilient
All installations comply with the California Electrical Code (2023), Title 24 Energy Standards, and NFPA 70 (NEC) circuit design. We verify proper grounding for moisture-prone environments, GFCI protection where required (bathrooms, kitchens), and correct circuit sizing for motor loads. For fire-rebuilt homes, we ensure exhaust systems include makeup air provisions to prevent negative pressure and support smoke evacuation. We provide stamped plans and load calculations satisfying LA County building officials and energy code inspectors.
Mountain-grade durability for challenging terrain
Altadena exhaust systems require materials designed for mountain UV exposure, temperature swings, and ash deposits. We use stainless-steel dampers and louvers, marine-grade corrosion-resistant backdraft dampers, and UV-resistant conduit for exposed runs. For wet environments (bathrooms, kitchens), we specify moisture-rated wire insulation and corrosion-resistant junction boxes. We ensure proper sloping of ductwork to prevent water accumulation and ash buildup, seal all penetrations with appropriate moisture and fire-rated barriers, and install quality exhaust fans rated for continuous duty. Electrical connections are torqued to spec, labeled per NEC, and documented.
Custom routing for challenging hillside spaces
No two Altadena homes are identical—different attic configurations, ceiling heights, and structural limitations require custom solutions. We survey each project carefully, identifying optimal ductwork routing that minimizes elbows and length (reducing noise and power), respects architectural features, and works within space constraints. For multi-story hillside homes, we plan vertical runs and structural support. We coordinate with HVAC contractors to ensure ductwork arrives before electrical rough-in, and we pull wire through established pathways. For fire rebuilds, we integrate ventilation wiring planning from the architectural phase—ensuring optimal layouts and avoiding rework.
Frequently Asked Questions
Do I need special ventilation for wildfire smoke in Altadena after the Eaton Fire?+
Yes. Many Altadena families are installing ERV/HRV systems with makeup air provisions and MERV filters to filter wildfire smoke and ash from outdoor air while recovering heating/cooling energy. These systems prevent negative pressure that can draw smoke inside and help maintain indoor air quality during fire seasons. We can design and install fire-resilient ventilation systems tailored to your home’s needs.
What size circuit does my bathroom exhaust fan need?+
Standard residential bathroom fans use 20A dedicated circuits at 120V. Modern or dual-fan systems may require 30A or 240V circuits. For whole-house ventilation or ERV systems, sizing may be different. We perform load calculations and recommend appropriately sized circuits based on your specific fans and mountain environment demands.
How do exhaust fans help with Altadena’s mountain humidity and fire seasons?+
Exhaust fans remove humidity from bathrooms and kitchens before moisture can condense, rot wood, or promote mold growth. During wildfire smoke seasons, ERV systems with makeup air and filtration remove dangerous outdoor air pollutants before they enter your home. Humidity-sensing fans automatically activate as moisture levels rise—removing excess moisture efficiently without excessive runtime.
What’s an ERV system and why do fire-rebuilt homes need one?+
An Energy Recovery Ventilation (ERV) system exchanges stale indoor air for fresh outdoor air while recovering heating/cooling energy—improving efficiency and indoor air quality. For fire-rebuilt homes, ERV systems include makeup air provisions and MERV filtration to remove wildfire smoke and ash from outdoor air before it enters. This is increasingly required in Altadena’s fire-prone areas and supports families’ respiratory health during fire seasons.
