Most A/C complaints in this climate are not about a broken compressor. They are about a slow refrigerant migration, a clogged drain, or a cabin filter that has quietly turned into a sponge. We diagnose the system before we touch the refrigerant.
Our climate-control routine treats the whole circuit — compressor, condenser, expansion valve, evaporator and ductwork — as one connected system. We measure pressures on both sides, check the temperature drop across the evaporator, and inspect the cabin air path before we sign anything off.
What we check
- High and low side pressure across idle, mid-rev and full-load
- Vent temperature with a calibrated probe at four cabin outlets
- UV dye leak inspection across condenser, hoses and service ports
- Cabin filter condition, drain line flow and evaporator surface inspection
- Climate-control electronics fault scan
What we typically replace
- Refrigerant top-up or evacuation/recharge to manufacturer weight
- Cabin air filter (HEPA grade available on request)
- O-rings, valve cores and service-port caps
- Compressor or expansion valve when failure is documented
What gets logged in your file
- Vent temperature reading before and after service
- Refrigerant weight charged into the system, recorded to the gram
- Photo evidence of any leak point identified
- Cabin filter swap photographed against your file
A cold cabin is not magic. It is a closed circuit working at its design pressure — verifiable, measurable, and worth treating as such.
