Water around your indoor AC unit is never something to ignore. What starts as a slow condensate issue can quickly turn into ceiling damage, insulation problems, and electrical risk.
Underwood Heating & Air Conditioning diagnoses AC leak causes across Phenix City, Auburn, Opelika, and East Alabama. We stop active leaks, correct the root problem, and verify safe drainage before we leave.

Most AC water leaks are tied to blocked drains, frozen coils, or installation and pump issues. This page helps you do safe checks first, then shows when immediate professional service is the smarter move.
“Great service, fair pricing, and super reliable. Quick to respond and very professional.”
Symptoms: Water pooling near air handler, intermittent shutoffs, or musty odor near mechanical closet.
DIY check: Inspect visible drain outlet for slow or no flow while system runs.
Professional fix: Clear line blockage, sanitize drain path, and test safety switch shutoff/restore sequence.
Symptoms: Persistent dripping under indoor unit despite normal system operation.
DIY check: Look for rust staining or obvious cracks around pan edges if accessible.
Professional fix: Repair or replace damaged pan and confirm proper pitch and drainage.
Symptoms: Large water release after periods of weak airflow or warm air complaints.
DIY check: Check for prior ice signs on refrigerant lines or coil panel.
Professional fix: Resolve freeze cause (airflow/refrigerant issues), then restore normal condensate control.
Symptoms: Combination of poor cooling and water around indoor equipment.
DIY check: Replace filter and verify return path is unobstructed.
Professional fix: Evaluate airflow and static pressure to prevent recurring coil freeze and leak cycles.
Symptoms: Water backup in attic or closet installations where gravity drain is not used.
DIY check: Listen for pump operation during cooling cycles; silence may indicate failure.
Professional fix: Repair/replace pump, clear discharge tubing, and verify overflow protection.
Symptoms: Slow recurring leaks after prior work or after system replacement.
DIY check: Check for uneven standing water in visible pan areas.
Professional fix: Correct installation angle, adjust drain routing, and confirm full drainage under load.
Symptoms: Active dripping near piping joints or at unexpected points in attic/closet.
DIY check: Visually inspect exposed joints for separation or cracked PVC.
Professional fix: Reconnect/replace line sections and pressure-test flow integrity.
Symptoms: Recurring freeze-thaw water events with weak cooling performance.
DIY check: If icing is visible, shut cooling off and run fan only.
Professional fix: Complete refrigerant diagnostics, leak repair if needed, and recharge to spec.
Identified the problem? We diagnose and fix it same day.
Spring is our busiest season — book now to avoid the wait.
Step 1: Is there active leaking near electrical components or ceiling penetration?
If yes: Turn system off immediately and request emergency service.
If no: Go to Step 2.
Step 2: Is the filter dirty or airflow weak from vents?
If yes: Replace filter and monitor whether leak slows after 20-30 minutes.
If no: Go to Step 3.
Step 3: Do you see or suspect ice on refrigerant lines/coil area?
If yes: Switch cooling off, fan on, and schedule same-day diagnosis.
If no: Go to Step 4.
Step 4: Is drain outlet showing little or no condensate flow?
If yes: Likely drain restriction or pump issue. Book professional drain service.
If no: Go to Step 5.
Step 5: After checks, is water still collecting around unit?
If yes: Call for leak diagnosis before structural or electrical damage spreads.
If no: System stabilized; schedule preventive maintenance to avoid repeat overflow.
Move valuables away from leak area and place absorbent protection while waiting for service.
Restricted airflow can freeze coils and create large thaw events that look like sudden leaks.
No flow during active cooling often points to drain blockage or pump issues.
Switch cooling Off and fan On if ice is suspected to prevent additional water release from thaw cycles.
If water is close to wiring or breaker panel areas, treat as urgent and request emergency dispatch.
Caution: Do not open electrical panels or attempt internal repairs.
Water leak repairs vary based on whether the issue is drain-only, airflow-related, refrigerant-related, or installation-related.
You receive clear repair options after diagnosis, including what must be fixed now versus what can be scheduled.
We explain preventive steps so the same leak pattern does not return during peak summer humidity.
Same-day AC leak diagnosis is available throughout Phenix City, Auburn, Opelika, and nearby East Alabama communities. Emergency slots are prioritized when water threatens ceilings or electrical areas.
Frequently Asked Questions
The most common causes are clogged drain lines, frozen coils thawing, damaged drain pans, or pump problems in attic and closet systems.
It can be. If water is near electrical components, dripping through ceilings, or pooling rapidly, turn the system off and request emergency service.
If leak is minor and away from electrical risk, brief operation may be possible while monitoring. If water is active or ice is present, shut cooling off and call.
Slow or absent drain flow during cooling, float-switch shutdowns, and water near indoor unit are strong signs of drain restriction.
Yes. Restricted airflow can freeze the coil, and thawing ice can overflow pans and drain capacity.
Yes. Same-day service is common in Auburn and Opelika, with emergency dispatch for active water-damage risk.
Yes. We diagnose, repair, or replace condensate pumps and verify proper overflow protection.
Not always. Some leaks are symptoms of airflow, refrigerant, or installation issues, which require full diagnosis.
Yes. You get clear options after diagnosis and before repair begins.
Yes. Regular maintenance reduces drain blockages, coil freeze events, and airflow problems that lead to recurring leaks.
