Ice on the copper lines
Low airflow or low charge. We find which.
Iced suction line with a dirty filter is not a refrigerant sale. We check airflow first.
If the indoor fan runs but the house stays hot, the outdoor unit, refrigerant circuit, or airflow is the real question — not “add Freon and leave.”
If the search that brought you here was “ice on AC lines,” start with a test, not a replacement pitch.
We test temperatures, static pressure, electrical on the condenser, and whether the coil is iced. A $69 diagnostic documents the reading before any repair quote.
On this call we confirm the symptom you described — ice on the copper lines — before we open a price book.
You approve any repair after the findings are written down. Diagnostic visits are a flat $69. New installation estimates are free in-home with a load calculation — not a number invented from square footage on Zillow.
A “recharge” without a leak test is a second service call in two weeks. We do not top off a sealed system as a business model.
A company that skips testing on ice on AC lines will skip it on the next call too. We would rather lose a job than install the wrong thing.

Inland heat (Pleasanton, Livermore, Concord) and marine air (Alameda, Daly City) are different loads. A note written for Pleasant Hill is not automatically right for a fog-belt house. We treat them that way.
