AC Leaking Water Inside the House
Free referrals to independent local air conditioning contractors serving Hemet, San Jacinto, and nearby San Jacinto Valley communities.
Water leaking from the indoor AC unit usually means a clogged condensate drain line, a cracked or rusted drain pan, a failed condensate pump, or a frozen coil melting. Turn the AC off, protect floors and ceilings, and check the filter. HomeGuide estimates a drain line flush at $75 to $250 nationally.

Why does an AC make water?
Air conditioners pull moisture out of indoor air. That water drips into a pan under the indoor coil and drains outside or into a plumbing drain. When that path is blocked, water goes where it shouldn’t.
What are the common causes?
- Clogged drain line: algae and sludge build up in the pipe.
- Rusted or cracked drain pan: common in older systems.
- Failed condensate pump: in systems that pump water uphill.
- Frozen coil: melting ice can overflow the pan. See frozen AC coil.
- Disconnected drain line: after other work in the attic or closet.
Why is an attic air handler leak urgent?
Many Hemet-area homes have the indoor unit in the attic or a closet. An overflowing pan in the attic can stain or damage ceilings quickly. If you see water on the ceiling below the unit, turn the AC off and call.
What do drain repairs cost?
HomeGuide national estimates: drain line flush or cleaning $75 to $250. Pan or pump replacement varies by system.
When should you call an emergency AC pro in Hemet?
Call for urgent help, and call 911 first where noted, if any of these apply:
- Someone has signs of heat stroke: confusion, slurred speech, fainting, very high body temperature, or hot skin. Call 911 and start cooling them right away.
- The AC is out during a heat wave and someone at home is an older adult, an infant, pregnant, or has a medical condition that heat makes worse.
- The outdoor unit or air handler smells like burning, sparks, or keeps tripping the breaker. Turn the system off at the thermostat and breaker.
- Water is leaking from the air handler into ceilings, walls, or flooring.
- The AC runs but indoor temperatures keep climbing on a hot day.
- You smell gas near a gas furnace or package unit: leave and call 911 or SoCalGas from outside.
If someone shows signs of heat stroke, or you smell gas, call 911 first. Don't wait for a contractor.

What do people ask about AC repair in Hemet?
Is it normal for water to drip outside from a pipe?
Yes. A small pipe dripping outside while the AC runs is the condensate drain doing its job.
Why did my AC shut off when the drain clogged?
Many systems have a float switch that turns the AC off when the drain pan fills, to prevent water damage.
Can I clear the drain myself?
Some homeowners clear the outdoor end of the line with a wet/dry vacuum. If water keeps backing up, have a technician check the pan, pump, and trap.
