Exhaust Fan & Ventilation Wiring in Glendale

Replacing a like-for-like fan on an existing circuit may be permit-exempt in some cases, but adding a new circuit, relocating equipment, or modifying exterior terminations typically requires an electrical/mechanical permit from Glendale Building and Safety. We’ll review your scope, pull any required permits, and meet the inspector to finalize the sign-off.

Yes. We use stud finders, borescopes, and flexible drill/bit systems to fish wiring with minimal openings. We often cut at the fan opening and a small access point near a joist bay, keeping patches small. Our goal is clean routing that preserves finishes while meeting code and airflow targets.

We calculate CFM using room volume and duct path resistance per ASHRAE 62.2. High ceilings or long, restrictive ducts may require a higher-capacity fan or larger duct diameter. For example, a typical 8' x 10' bath with a 10' ceiling often needs 80–110 CFM, especially if the duct run is long or has multiple elbows.

An attic fan with proper intake and a thermostatic control can reduce attic heat load and help your home feel cooler. We recommend insulated ducts, sealed penetrations, and smart controls to avoid pulling conditioned air from the house. During wildfire smoke events, we advise disabling attic ventilation or using filtered strategies to protect indoor air.

Yes. We frequently work in multi-family and condo buildings along Brand and Central. We follow HOA guidelines, use MC or EMT as required, and coordinate with building management and mechanical contractors. We also schedule within allowed work hours and protect common areas during the project.

Most bathroom or laundry fans draw low amperage (often under 1 amp). We’ll evaluate your panel load, breaker space, and AFCI/GFCI requirements. If space is tight, we can sometimes use a dual-function breaker or consolidate circuits while maintaining code compliance and safety.
