A system running but not cooling almost always comes down to charge, airflow, or a failing component — we test all three.
A tech who explains superheat and subcooling readings instead of just saying 'it's low on freon'.
A system that's technically running but not actually cooling the house is one of the most misdiagnosed hvac complaints there is, which is exactly why ac repair calls in Washington, DC get treated with urgency, not a next-available-Tuesday slot.

Most AC repair problems give some warning before they turn into warm air blowing from the vents, ice forming on the copper line, or a condenser fan that's stopped spinning outside — catching it early usually means a shorter, cheaper fix.

The number on your quote is the number on your invoice.
We check superheat and subcooling against manufacturer spec before touching the refrigerant charge.
Every job starts with a real diagnosis, not a guess — here's the full scope of what our AC repair technicians handle across Washington, DC.
Repeated low-charge calls on the same system usually mean an unrepaired leak from a prior visit elsewhere. This is one of the most requested AC repair calls we get across Washington, DC.
A condenser fan that's stalled or running slow lets head pressure spike, which can trip the compressor's high-pressure safety. This is one of the most requested AC repair calls we get across Washington, DC.
A dirty or frosted evaporator coil restricts airflow and drops cooling capacity fast. This is one of the most requested AC repair calls we get across Washington, DC.
A failed compressor is often the last domino, not the first. This is one of the most requested AC repair calls we get across Washington, DC.
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 Washington, DC.
Ductless systems fail differently than central air — we service indoor head units, line sets, and outdoor condensers. This is one of the most requested AC repair calls we get across Washington, DC.

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.

House was sitting at 84 degrees and the vents were blowing lukewarm air.
Outdoor unit had ice forming on the copper line which I'd never seen before.
They caught it before the compressor overheated and swapped the fan motor same visit.
Their tech knew it on sight and had a replacement part on the truck.

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.
Every system has a manufacturer-specified charge amount — we don't top off blind, we charge to spec using superheat/subcooling readings.
We carry recovery equipment rated for legacy refrigerants.
Yes — indoor head units, outdoor condensers, and line sets all fall under our service scope.
