Walnut sits in the eastern San Gabriel Valley hills. Hot summers regularly reach 95 to 105 degrees Fahrenheit, with hilly terrain creating localized heat pockets that vary between properties. Long cooling season runs April through October. Cool winter nights bring real furnace demand from November through February. Established residential community with many homes in the 10 to 20 year HVAC system age range produces consistent service demand.
Hilly terrain in Walnut produces meaningful microclimate variation - hillside properties at different elevations and exposures can experience noticeable temperature variation. AIRONE's Manual J load calculation accounts for specific property characteristics rather than zip-code averages. Many homes in the 10 to 20 year age range are also in the prime maintenance-versus-replace decision window - written assessments help Walnut homeowners make informed decisions.
