Same-day mini-split installation for Carson homeowners

Most mini-split installation calls I run in Carson share a few things in common: post-war ranches built late-1950s through mid-1960s when Dominguez Hills was still farmland — single-story, 1, with the kinds of HVAC quirks that come from that vintage. Mini-splits are the most over-installed and under-serviced HVAC product in the South Bay right now. ADU contractors are slapping them in at the rough-in stage with zero load calc and the wrong head sizing — I get those callbacks 18 months later.

What's unique about HVAC in Carson:

• Housing stock here is post-war ranches built late-1950s through mid-1960s when Dominguez Hills was still farmland — single-story, 1,200 to 1,800 sq ft, with original ducting in many of them.
• way less ocean breeze than Torrance, several degrees hotter in summer, and the refinery air can do a number on outdoor coil fins.
• Common mini-split installation jobs in Carson: 20-year-old condensers limping through August, undersized ducts pushing way too much air, leaky returns sucking attic air, the occasional Goodman-to-Carrier replacement.

The problems I usually find on Carson mini-split installation calls

• Drainage uphill. condensate has to go down. I've fixed dozens of installs where the drain runs uphill 'just for a bit.'
• Communication wire faults. the wire between condenser and head carries data. Wrong gauge, kinks, or splices = E1, E5, or P1 error codes.
• Oversizing the head. biggest mini-split mistake. A 24k BTU head in a 200 sq ft ADU short-cycles and never dehumidifies.
