What NextGen does

Repair, replacement and maintenance for residential and commercial systems — done right the first time, in Greg's words.

Ducts & airflow
Duct install, repair and sealing. If rooms cool unevenly or the system runs loud, the ducts usually explain it.

Insulation & attic
Attic insulation and clean-outs — the upgrade that makes the AC's work actually stay in the house.

Maintenance plans
Seasonal tune-ups that keep repairs small. One customer is on year six of servicing with Greg.
Call about it →Air quality, thermostats, something odd?
Indoor air quality, smart thermostats, a noise you can’t place — describe it and you’ll get a straight answer.
(310) 614‑7223 →The second opinion
“Both told me I basically needed a major repair or full replacement… steering me toward spending $4,000+. Then John showed up — and it was a completely different experience.”
We fix what others replace. Another customer put it this way: “I saved a lot of money as previous hvac companies quoted me for 10k.” When a unit really is done, you’ll hear exactly why — and the estimate for the change-out is free.

Straight answers
Asked often.
Another company says I need a whole new system. Do I?
Maybe — but get the second opinion first. One customer was told by two companies she needed a $4,000+ repair or full replacement; John repaired the unit instead. Another saved against a $10k quote. If the unit really is done, you'll hear exactly why, and the change-out estimate is free.
Are you licensed and insured?
CSLB C-20 license #1040723 — held by Nextgen HVAC Inc with a $15,000 bond and workers' compensation on file. You can verify it at cslb.ca.gov before anyone comes out.
How fast can someone come out?
Often same-day: "Greg responded to our service request the same day we called" is a Google reviewer's words. Call (310) 614-7223 and say what the system is doing.
What does a repair cost?
It depends on the fault, which is why the diagnosis comes first and the options come with real prices. Their published Yelp offer takes 15% off repairs of $600 or more, and every job is backed by the owner's posted promise: all jobs guaranteed or your money back.
Do you service my area?
The shop runs from Van Nuys with a second location in Arcadia — covering the San Fernando Valley, Burbank, Glendale, Pasadena and the San Gabriel Valley. Residential and commercial.
