Old wall furnace, sketchy install

“Bought a 1947 Craftsman near 14th and Pacific Coast Highway — gravity wall furnace was original. Two companies refused to touch it; RedAlert's tech actually carries the parts for old Williams units. He brought it back into safe operation (CO test, draft check, manometer reading on gas pressure), then walked through long-term replacement options without pressuring me. We're scheduling a mini-split retrofit with them next month.”

Salt-air corrosion damage

“Our 6-year-old AC was already failing — coastal corrosion ate through the condenser coil at the bend. Tech showed me the green oxidation on the copper. They sourced an exact-match replacement coil through their Goodman distributor (3-day wait), pulled the system properly (vacuumed to 250 microns), recharged. Also coated the new coil with a dielectric anti-corrosion spray that the dealer offers but rarely sells. Smart, future-thinking work.”

Saved us during a 96° heatwave

“Our 12-year-old Carrier Performance 16 quit on the hottest Saturday of August. Called at 2:14 pm, tech Marco was in our driveway near Sepulveda by 3:05 — under an hour. Diagnosed a failed dual-run capacitor (45/5 µF) in fifteen minutes, had the OEM part on the truck. Total visit was 90 minutes. He also flagged that our condenser fins were salt-pitted from the marine layer and showed me how to rinse them quarterly. Honest pricing, no upsell.”

Third year on the maintenance plan

“Been on their twice-yearly tune-up plan since 2022 — Lennox Elite 16ACX outside, EL296V furnace inside. They always text the day before, show up in the window, and email the report with static-pressure and refrigerant subcooling numbers. Last spring they caught a slow R-410A leak at the schrader valve before it turned into a $1,200 problem. Worth every dollar of the $189/year membership.”

Honest diagnosis saved $7,650

“Another company had quoted me $8,000 for a complete furnace replacement claiming a cracked heat exchanger. RedAlert sent a tech with a borescope camera, ran the unit, did a CO test in the supply plenum (came back at 0 ppm), and showed me on screen there was no crack — just a failed hot-surface ignitor. $350 part + labor and the 80% AFUE Goodman has been running clean for ten months. Will never call anyone else.”

New 17 SEER2 install — solid work

“Replaced a 19-year-old 10 SEER unit with a Carrier Performance 17 (3-ton) and matching evaporator coil. Crew did the manual-J load calc, oversized the line set by an inch, pulled a deep vacuum (500 microns held for 20 min — they showed me the gauge). Took a full day plus a return for permit close-out. Lost a star only because the original quote underestimated the disconnect-box upgrade by $180; they ate the difference without asking.”
