Local homes
Simi Valley housing and HVAC
Most homes are single-story or two-story stucco houses with gas furnaces and central AC, with ducts in attics. Many 1960s and 1970s homes are on second- or third-generation equipment and original ductwork.
Simi Valley has hot, dry summers with frequent days in the upper 90s and 100s, cool nights and mild winters. Santa Ana winds bring extreme fire danger, and fires like the 2019 Easy Fire and 2024 Mountain Fire have burned nearby.
Permits and seasonal timing in Simi Valley
The City of Simi Valley Building and Safety Division issues mechanical permits, and California requires C-20 licensed contractors and Title 24 compliance, which often includes duct leakage testing.
Valley heat
Long hot stretches push older AC systems and attic ducts hard, and failures often come during the first heat wave of the year.
Wildfire smoke
Santa Ana-driven fires bring heavy smoke, so high-MERV filtration and sealed returns matter.
Aging tract-home systems
Many 1960s and 1970s homes have older furnaces, AC units and ducts ready for replacement.
