If you're searching for furnace installation, you're probably already dealing with one or more of these symptoms: Furnace over 15 years old, Frequent furnace repairs, High heating bills, Uneven heating, Safety concerns with old unit. Each of those points to a specific category of failure, and the right diagnostic path starts with measuring before guessing — that's the difference between a same-day fix and a return visit.
Typical furnace installation pricing runs $3,800–$8,400 for standard scope. Our $89 diagnostic fee is waived with repair — meaning if we do the work, you don't pay the diagnostic on top. We provide a detailed written quote before any work begins, broken down by part, labor, and any optional upgrades. There are no "trip charges," no "fuel surcharges," and no hidden line items.
What's included in the $89 diagnostic: a full system inspection, electrical testing (capacitor microfarad reading, contactor pitting check, motor amp draw), refrigerant pressure readings (for cooling work), combustion analysis (for gas heating work), static-pressure measurement on the ductwork, and a written report with the readings. If the issue is non-obvious, we run a thorough enough diagnostic that we won't have to come back for the same problem.
Across the South Bay we run roughly 5K+ furnace installation jobs per year, which gives us pattern recognition that one-off shops don't have. The same five or six failure modes account for the vast majority of calls.
We've refined this process over 15+ years of field work in South Bay. The goal is to fix the issue on the first visit when at all possible, and to never charge for parts you don't actually need.
Every technician dispatched for furnace installation is NATE-certified (industry gold standard for HVAC competency), EPA Section 608 Universal certified (federally required for refrigerant work), and has at least 5 years of residential or light-commercial field experience. We background-check every team member, drug-test annually, and require continuing-education hours each year on new equipment from Carrier, Trane, Lennox, Goodman, Rheem, Daikin, and the rest of the major brands.
Trucks are GPS-tracked so dispatch can give you a real-time ETA, not a four-hour window. Each truck carries the most common parts for furnace installation work — capacitors, contactors, hot-surface ignitors, flame sensors, common condensate float switches, and a stocked refrigerant kit — so most repairs happen in a single visit.
We're fully licensed & insured, carry comprehensive general liability coverage, and pull permits on any work that requires one.

“Replaced a 25-year-old 80% AFUE atmospheric furnace with a Trane S9V2 (96% AFUE, two-stage variable-speed). Crew of three was on-site 7am to 3pm. They re-did the gas line to 1/2" black iron with proper drip leg, ran new 2" PVC vent and combustion-air through the side wall (not the roof — much smarter), and installed a condensate neutralizer. Permit, inspection, all handled.”

“Inherited the house, original 1990 Day & Night gravity furnace was a fire hazard — heat exchanger crack, no safety controls. They installed a Carrier 59SC5 96% modulating furnace with all-new venting. Required Lomita permit + SoCalGas inspection (passed first try). Pricing was lower than two competitor quotes for better equipment. Job was done in 9 hours.”

“Replaced the entire system — Trane S9V2 furnace + XR16 AC + matched coil + ECM blower. Two-day install. They ran new line set, replaced the disconnect box, upgraded the breaker, and properly secured the gas line with a new sediment trap. Pulled both permits, both inspections passed first time. Bills dropped 22% in the first comparable month. A real upgrade.”

“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.”

“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.”

“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.”
