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.

True 24/7 — answered at 11 pm

AC compressor seized during a dinner party in South Redondo, 11:14 pm. Called the emergency line — a real human answered, not an answering service. Tech arrived 47 minutes later. Couldn't get a new compressor at midnight obviously, but he diagnosed the failure, isolated the start capacitor, and wired up a window unit from his truck for the bedroom so we could sleep. New compressor went in two days later. That's service.

Diagnosed what two others missed

Two prior shops said our AC just needed a recharge — kept freezing up two weeks later. RedAlert ran a full electronic leak detection sweep with a Bacharach H-10 Pro, found a pinhole leak at a soldered joint on the suction line buried in the attic. Repaired it, evacuated the system, recharged with the exact factory subcool target. Twelve months later, still running. Should have called them first.

Beach-house ducts were a disaster

Our 1968 Riviera Village place hadn't had ducts cleaned in over a decade. They used a Rotobrush truck-mounted system, sealed every register, and showed me before/after photos and the debris bag. Wife's allergies have noticeably improved. Also found a disconnected return collar in the crawl space — fixed it on the spot for $90 instead of a separate trip. Three guys, four hours, done right.

Switched to a Mitsubishi heat pump

We replaced our gas furnace + AC with a Mitsubishi M-Series hyper-heat pump (2-zone). Daniel and his crew did the manual-J, sized it correctly (no ‘rule of thumb 1 ton per 500 sqft' nonsense), and ran the line set through an attic chase rather than down the side of the house. Energy bill dropped 31% on the first SCE statement. They also handled the rebate paperwork for the $3,200 SCE/SoCalGas Energy Star incentive.

20 SEER2 variable-speed retrofit

We're in the Tree Section, 1,950 sqft. Got quotes from three companies for a Trane XV20i variable-speed system. RedAlert came in middle on price but only one to actually run a Manual-J load calc instead of guessing. Install was 1.5 days, they coordinated with the SCE inspector for the permit, and the system runs whisper-quiet (47 dB at 10 ft). Lost a star only because the line-set covers don't match the stucco color exactly — minor.
