A system running but not cooling almost always comes down to charge, airflow, or a failing component — we test all three.
Straightforward flat-rate pricing, quoted after diagnosis.
If you're dealing with warm air blowing from the vents, ice forming on the copper line, or a condenser fan that's stopped spinning outside, you already know a system that's technically running but not actually cooling the house is one of the most misdiagnosed HVAC complaints there is.

Hard-starting, humming-but-not-spinning, or tripped breaker symptoms get tested with a start capacitor check before any compressor is condemned. Techs handling compressor diagnostics carry the specific parts and tools this job calls for, not a generic kit.
We verify the low-voltage circuit before assuming the outdoor unit is at fault. This is one of the most requested AC repair calls we get across Harvard, MA.
Ductless systems fail differently than central air — we service indoor head units, line sets, and outdoor condensers. Techs handling ductless mini-split diagnostics carry the specific parts and tools this job calls for, not a generic kit.

Tell us whether the air is warm, the unit is icing, or it's not running at all — that detail changes what parts ride along.
Techs arrive with manifold gauges and common capacitor/contactor stock already loaded.
Superheat, subcounting, and airflow readings get taken before any refrigerant is added.
Most refrigerant and component repairs wrap same-visit.

Turned out to be a slow leak at the schrader valve — they found it with dye, fixed it, and recharged properly.
Outdoor unit had ice forming on the copper line which I'd never seen before.
Condenser fan had completely stopped and the compressor was still trying to run.
Mini-split in the sunroom was throwing a code I couldn't find online.

Usually low refrigerant charge from an undetected leak, a dirty evaporator coil, or restricted airflow from a clogged filter.
Turn the system off, set the fan to run, and call — running a frozen coil makes the underlying problem worse.
Adding refrigerant without finding the leak just means another service call later.
We carry recovery equipment rated for legacy refrigerants.
