Coming home after a long day to find a puddle of water pooling under your air conditioning unit is enough to make anyone feel dismayed. Seeing all that liquid dripping from your AC likely indicates an issue that needs diagnosing and resolving. While a small amount of condensation forming on your air conditioner’s coils is normal, significant water leakage points to a problem. Several common causes of air conditioning units dripping water – from a clogged filter to a failed part. Unfortunately, most of these culprits behind a leaky AC will require calling in a professional for repair service.

This article explores the various reasons you may find your air conditioning unit dripping water everywhere. We’ll outline the potential causes, discuss when you can attempt a DIY fix versus when it’s best to call the pros and explain what to expect during a professional AC repair service. Equipped with the information here, you’ll be better prepared to tackle that puddle forming under your air conditioner.

What’s Causing the AC to Leak?

There are several common culprits behind an air conditioning unit dripping water. By understanding the potential causes, you can better pinpoint why your AC leaks and determine if it’s a DIY fix or requires calling in a professional.

1. Cold Weather Dripping

When outside temperatures plummet, the evaporator coils inside your air conditioning unit can end up with moisture accumulation that freezes. Once things start warming up again, that ice melts and leaks water everywhere. This water dripping from cold weather changes is usually minimal and will stop once temperatures rise again. Turn off your AC and wait for warmer weather before rerunning it.


2. Clogged Air Filter

A dirty air filter prevents proper airflow over your AC’s evaporator coils. This reduced airflow can cause the coils to freeze, like in cold conditions. Check your air filters and replace any that are clogged. Keeping them clean ensures good airflow and prevents frozen coils from leaking water.

3. Failed Condensation Pump

Some AC units have a condensation pump to remove water that collects internally. If this pump fails, moisture builds up and leaks out of the unit. Replacing a broken condensate pump requires professional expertise. Call an HVAC technician to assess and replace a faulty AC condensation pump.

4. Improper Installation

Incorrectly installed ductwork can create negative pressure and pull moisture into the air conditioning unit’s drip pan. Proper installation includes a vent line and p-trap to combat this. If your AC was not installed properly, contact the company to inspect and correct any issues leading to leaking water.

5. Clogged Drain Line/Hole

Drain lines carry away condensed water from the AC’s evaporator coils. A clogged drain line or drain hole will back up water inside the unit, forcing it to leak from other areas. Have an HVAC technician clear any obstructions in the condensate drain line or outlet hole. Regular maintenance helps avoid clogged drains.

6. Leaking Ductwork

Poorly sealed or insulated ductwork allows humid air to enter the system. This added moisture condensed on evaporator coils and dripped out. An HVAC pro can identify and close any leaking ducts carrying damp air where it shouldn’t go. Repairing damaged and deteriorating ducts prevents drips.

7. Low Refrigerant Levels

Not having enough refrigerant can cause AC evaporator coils to freeze up. The coils thaw and drip water when the air conditioner cycles off. Signs like reduced cooling suggest refrigerant leaks. Only certified HVAC techs can safely inspect, test, and top refrigerant levels.

A professional AC repair technician provides the proper diagnosis and solution for any underlying issues causing your air conditioning unit to drip water. Protect your home and health by getting all problems checked and fixed quickly.

When To Call a Professional

While minor dripping can sometimes be remedied with DIY fixes, consistent leaking or large amounts of water call for professional AC repair service.

If water is dripping from your air conditioning unit year-round rather than just during cold snaps, that indicates an underlying problem needs addressing. Trying basic troubleshooting like cleaning the filter or drain line, yet the leaking persists, means it’s time to bring in a pro.

Signs like reduced cooling capabilities, strange noises, mouldy smells, or pooling water suggest more serious AC issues beyond just a drip. Refrigerant leaks, faulty parts like a broken condensation pump, or damaged ductwork require an HVAC technician’s expertise.

Improper installation is another reason water drips from an AC, necessitating professional inspection and correction. Don’t delay in getting any suspected improper install issues checked.

Calling a qualified AC repair technician provides many benefits compared to DIY repairs. Licensed pros have the skills to diagnose problems accurately through testing and inspection. They have the equipment, tools and knowledge to fix the issue properly and avoid future breakdowns. Professionals get the job done quickly and safely.

Protect your home, health and AC system investment by calling in an expert at the first sign of significant leaking, reduced performance or other concerning symptoms. Their preventative maintenance also keeps minor problems from turning into big headaches.

What To Expect During an AC Repair Service

When calling in a professional for air conditioning repairs, technicians follow a general process to diagnose and fix the problem.

The repair visit starts with thoroughly inspecting the entire unit, inside and out. The technician will check the condenser outside, evaporator coils and drip pan inside and examine ductwork connections.

Through hands-on testing and troubleshooting, the technician works to pinpoint the exact cause of the issue. This helps them determine any needed repairs or if replacement of a defective part is required.

The technician will explain their findings and make recommendations on the best solution. This ensures the underlying problem is addressed correctly, not just the symptom of leaking water. They can advise if a damaged component needs replacing or a blocked drainage line needs clearing.

An experienced technician will discuss costs and service options to stay within your repair budget. They can outline if a temporary fix is available or a more extensive repair is required for optimal, long-term operation.

Quality AC companies work transparently to help you make an informed decision. They want you to understand the problem, solutions and costs. With the technician’s expertise, your AC issue can be resolved efficiently and affordably, avoiding future breakdowns. You’ll stay cool through the hot summer ahead.

DIY Interim Fixes

While waiting for a professional repair, you can do quick DIY checks for a leaking air conditioner.

First, switch off the AC unit immediately to prevent further dripping issues. Make sure the air filter is clean and debris-free. Check that the condensate drain hole or pipe is not clogged, preventing water from properly draining out.

Also, ensure the exterior condenser unit has adequate airflow and is not obstructed by plants or debris. These simple interim fixes may provide temporary relief until a technician can properly diagnose and repair the problem. However, contact a professional promptly for any persistent leaking.
