Safe first steps, before the call. Nothing here needs a tool.
If water is near an outlet or cord, don’t touch them. Switch the system off at the thermostat, then at its breaker. Don’t stand in water to reach the breaker panel; if the panel is wet or you’d have to stand in water, leave it and call.
Keep people off the wet floor and away from the unit.

Everything else about this problem
Is it an emergency?
Is a Kenmore HVAC system leaking water an emergency?
Usually urgent, and it can be an emergency. Turn the system off at the thermostat, soak up standing water and keep it away from outlets and the unit's wiring. If water is coming through a ceiling or reaching electrics, switch off the breaker and treat it as an emergency.
Symptoms & causes
Your Kenmore HVAC unit is likely leaking water if you observe puddles around the indoor air handler or furnace, or notice dripping from the condensate drain line. This often indicates a clogged condensate drain, a frozen evaporator coil, or a cracked drain pan, all common issues with Kenmore systems. You might also detect a musty odor or experience reduced cooling efficiency if the leak has been ongoing.
Tools & parts
To address a Kenmore HVAC water leak, you'll typically need a wet/dry shop vacuum, a stiff brush for cleaning, and a screwdriver for access panels. Specific parts might include Kenmore-compatible condensate drain cleaner tablets, PVC pipe cement and a new PVC elbow if the drain line is damaged, or a specialized drain pan sealant for minor cracks. Always ensure you have appropriate safety gear like gloves and eye protection before starting any work.
Safety first
Before attempting any inspection or repair on your Kenmore HVAC, immediately turn off all power to the unit at both the thermostat and the main electrical breaker to prevent electrocution. Water near electrical components poses a severe shock hazard, so avoid contact with any wet wiring or connections. Promptly clean up any standing water to prevent slip hazards, mold growth, and further damage to your home's flooring or structure.
When to call a pro
A professional Kenmore HVAC technician is required if you suspect a refrigerant leak, which often manifests as ice on the evaporator coil even when the drain line is clear. Major component failures like a faulty compressor or a damaged evaporator coil, indicated by the unit running but not cooling effectively, also necessitate expert intervention. Additionally, if the leak persists after basic troubleshooting or if you're uncomfortable working with electrical components, it's best to call a certified HVAC specialist.
Questions people ask
Why is my Kenmore HVAC leaking water?
The most common reason for a Kenmore HVAC unit to leak water is a clogged condensate drain line, which prevents the water collected during the cooling process from draining away. A frozen evaporator coil, often due to low refrigerant or restricted airflow, can also melt and overflow the drain pan, leading to leaks.
Can I fix a Kenmore HVAC water leak myself?
Many minor leaks, especially those caused by a simple clog in the condensate drain line, can be resolved by a homeowner with basic tools and knowledge. However, issues like a cracked evaporator coil, a refrigerant leak, or a failing pump require the expertise of a professional Kenmore HVAC technician for safe and effective repair.
How often should I check my Kenmore HVAC for leaks?
It's advisable to visually inspect your Kenmore HVAC unit's condensate drain pan and line monthly during peak cooling season to catch potential clogs early. Annual professional maintenance for your Kenmore system can also help prevent leaks by ensuring all components are clean and functioning correctly.
