Every job starts with a real diagnosis, not a guess — here's the full scope of what our Knightsen, CA technicians handle.
We service central air, packaged units, and ductless mini-splits, and we size every new installation with an actual load calculation rather than matching the old unit's tonnage on a guess. Refrigerant leak detection uses electronic detectors and UV dye, not a repeated top-off that never addresses the actual leak. Techs handling ac repair & installation carry the specific parts and tools this job calls for, not a generic kit.
Every furnace call starts with a combustion analysis and carbon monoxide safety check before any repair recommendation, because a cracked heat exchanger is a safety issue first and a repair line item second.

Techs handling heating & furnace services carry the specific parts and tools this job calls for, not a generic kit.
Leaky, disconnected, or undersized ductwork can waste a significant share of a system's output before it ever reaches a vent — we test static pressure and duct leakage rather than sealing blind. Airflow balancing and damper adjustment are included when uneven room temperatures point to a distribution problem rather than a system fault. Techs handling ductwork & indoor air quality carry the specific parts and tools this job calls for, not a generic kit.
Phone triage happens before a truck rolls — gas smell, smoke, or burning odor reports get immediate safety instructions and top-priority routing. After-hours pricing is disclosed on the call, before dispatch, so there's no surprise on the invoice. Techs handling emergency hvac service carry the specific parts and tools this job calls for, not a generic kit.
Twice-yearly tune-ups, once ahead of cooling season and once ahead of heating season, catch the small issues that turn into mid-season breakdowns if left alone.
