AC Troubleshooting · Article 5 of 25
Quick answer: Air conditioners collect moisture while cooling, but that water should leave through the drainage system.
Understanding the issue
Air conditioners collect moisture while cooling, but that water should leave through the drainage system. A blocked drain, damaged pan, or thawing frozen coil can allow water to appear where it does not belong.
What homeowners can do
If water is reaching a ceiling, floor, or electrical equipment, stop using the system and request service. Photograph the visible leak from a safe location. Do not climb into a difficult attic or bypass a water safety switch to keep the AC running.
How Francisco’s Cooling & Heating can help
Francisco’s Cooling & Heating can investigate where the water originates and whether drainage, airflow, or another fault is responsible. A stain below an attic unit deserves attention even if the cooling still seems normal. Addressing the cause helps avoid a repeat leak.
