An air conditioner that runs without cooling usually has one of four problems: a dirty or iced evaporator coil, low refrigerant from a leak, a failed capacitor or contactor at the outdoor unit, or airflow restricted by a clogged filter or duct. Airmax Heating & A/C diagnoses and repairs all four in Westport, CT, with calls answered 24/7 at (866) 203-0469 and free written estimates on replacements.
What you can safely check yourself
- Replace the air filter if it is grey and loaded — this alone causes a surprising share of no-cool calls.
- Check whether the outdoor fan is spinning. If the compressor hums but the fan is still, that is usually a capacitor.
- Look for ice on the refrigerant line or indoor coil. If you see ice, shut the system off and let it thaw before anyone works on it.
- Make sure supply registers are open and return grilles are not blocked by furniture.
- Confirm the condensate pan is not full — a tripped float switch stops cooling by design.
What needs a technician
- Refrigerant is not a consumable. If it is low, there is a leak, and adding charge without finding the leak just delays the same call.
- Refrigerant handling legally requires EPA Section 608 certification; Airmax has a Universal-certified technician on staff.
- Repeated freezing usually points to airflow or charge, and static pressure should be measured rather than guessed.
- A compressor that trips the breaker should not be reset repeatedly.
