Signs you need air conditioning service today
AC running but not cooling. Warm air from the vents with the system on. A frozen indoor coil. Water leaking around the air handler. An outdoor unit that won't start, won't stop, or trips its breaker. Rooms that used to keep up and don't anymore. Any of these is the system telling you something specific — and the specifics matter.
Before you call
A few minutes of homeowner checks can either fix the problem outright or save the technician time finding the real one. Confirm the thermostat is set to cool and the setpoint is below the room temperature. Check the air filter — a clogged filter will starve airflow and freeze the coil. Look at the breaker for the air handler and the outdoor unit. Check the condensate drain near the indoor unit for standing water. Walk around the outdoor unit and clear leaves, grass clippings, or anything blocking the coil. If none of that fixes it, call.
What we measure on an AC call
Every air conditioning repair visit starts the same way. A manometer reads static pressure to see whether the duct system is choking the equipment. The ALNOR balometer confirms airflow at the registers. Manifold gauges check refrigerant charge against measured superheat and subcooling. An infrared camera spots electrical hot spots and temperature problems a meter alone can't see. The numbers go on a written report and the repair recommendation falls out of them. You see the readings before you approve any work.
