What this means in Signal Hill
Homes built here in the 1980s and 1990s are generally past their original furnace, and a replacement should account for the walkout lower level’s exposed walls, which carry more heating load than a buried basement. Whether one system serves a three-level plan adequately, and whether the sidewall venting route suits an exposed elevation, are both worth settling during the assessment. Note the basement type and which floors underperform.
