AC Leaking? What Edmond Homeowners Should Do Before Calling a Technician
You’re Not Alone in Your Search for an AC Leaking Water Fix
When you see that there is water pooling around your air conditioner, or water dripping down through a ceiling vent; you know that you have some company. Finding a fix for an AC leaking water is one of the top searches done by homeowners in Edmond, OK during Oklahoma’s extremely long and hot summers.
This article will explain the reasons behind AC leaks, what you can look at on your own, and when it is necessary to call in a professional. Early action can help you avoid costly repairs due to water damage and mold growth.
Why AC Water Leaks Are Common in Edmond Homes
In addition to lowering the temperature inside your house an air conditioner is designed to draw excess moisture out of the air. For people who live in Edmond during the summer months (when the humidity levels are over 60% for long periods) the amount of water that is produced by the air conditioning system (condensate) each day can be in excess of several gallons.
The purpose of this water is to flow safely away from the home through the proper drainage system. The moment it fails to do so, you will begin to see water leaks inside your home.
This issue is important in Edmond due to:
Extremely high temperatures and humidity levels found during summer months result in higher amounts of condensation being produced
A large portion of homes in Edmond have the air conditioning unit installed in their attics
Many older homes were built without modern safety features (such as a float switch) which would prevent the air conditioning unit from continuing to run if there was a problem with its drainage system.
Ignoring the leak from your AC unit can cause significant problems such as damage to your ceilings, drywall, mold growth (in 24 to 48 hours), and create potential electrical safety hazards close to the interior side of the indoor unit.
Common Causes of AC Leaks and What They Mean
Clogged AC Drain Line
The most common cause of an AC leaking water is a clogged condensate drain line. Over time, algae, dust, and debris build up inside the pipe and block proper drainage. When that happens, water backs up into your home.
Common signs include water pooling near the unit, musty odors, or the AC shutting off unexpectedly if a float switch is installed.
This is one of the few AC leaking water fixes homeowners can sometimes address safely.
Dirty Air Filter Causing Frozen Coils
The most likely reason for ac leaking water is when the condensate drain line is blocked by dirt, debris, and/or algae that have accumulated in the drain pipe over time. when the condensate drain line gets clogged, water will back up into your home.
signs of a clogged drain include standing water around the ac, musty smells, or your ac shutting down quickly (if there is a float switch installed) to prevent further damage.
this is one of the very few ac leaking water repairs you can do yourself safely.
Cracked or Rusted Drain Pan
Older systems may have drain pans that crack or rust over time. Even if the drain line is clear, water will still leak if the pan can no longer hold condensation.
This issue requires professional repair.
Improper Installation or Unlevel Unit
If the AC system is not level, water may not flow correctly toward the drain line. This is more common in older installations or homes that have settled over time.
Low Refrigerant Levels
Low refrigerant can cause coil freezing and repeated water leaks. Refrigerant issues must always be handled by a licensed HVAC technician.
FAQ: Should you keep running your AC if it is leaking water?
No. Continuing to run a leaking AC can increase water damage and repair costs.
What Edmond Homeowners Can Do Right Now
Before contacting an HVAC technician for assistance with your AC leak issue, there are several things you can do to protect yourself, your home and your equipment.
Step number one: locate and flip the circuit breaker that controls your AC system and switch the thermostat to OFF as well. This will help prevent additional water from building up inside your unit and also protect your electrical components.
Second, clean up all standing water around your unit. The faster you remove any water, the less chance you have of developing a mold problem and causing damage to your floors and drywall.
Third, check your air filter. If it's dirty or clogged, replace it now. Air filters typically need to be replaced every 30 to 60 days in Edmond during peak cooling months.
Fourth, if possible, inspect the drain line opening located on the bottom of your indoor unit. Add a small amount of distilled white vinegar to the drain line and let it sit for a few minutes. It may help loosen up some of the algae build-up. Do NOT use any harsh chemicals.
Fifth, if you can access the drain pan, visually inspect it for any cracks or rust.
A professional tip is to make sure your AC is installed in the attic by adding a float switch. A float switch automatically shuts off your AC system when water accumulates behind it. This little modification can save you from severe ceiling damage.
Why This Issue Is Especially Important in Edmond
When AC leaks occur in an Edmond home there are many potential hazards.
The high humidity of an Edmond summer leads to increased condensation on a daily basis. The installation of most AC systems in attics makes it difficult for homeowners to realize that their system has developed a leak until the damage is already quite extensive. Storms during the seasonal changes in weather cause indoor moisture levels to rise. A number of older homes in the Edmond area do not have the modern overflow protection that newer homes have today.
A clogged AC drain line in Edmond could become a significant repair cost in a matter of hours.
When you see water spots or stains on your ceilings, experience a loss of cooling efficiency or smell mildew or mold odors from your air conditioning system, it's time to take action. The best way to prevent leaks before they happen is to perform routine AC maintenance in Edmond.
Final Takeaways for Edmond Homeowners
Water leaks from an air conditioning system are a common occurrence during the summer months in Oklahoma. A majority of these issues occur due to a clogged drainage line or a dirty filter. In most cases, simply turning off the air conditioning system prior to major damage will resolve the problem. There may be occasions when basic troubleshooting can assist in resolving the leak without compromising safety. Proper ongoing maintenance significantly decreases the potential for future leaks.
Should the initial diagnostic steps fail to correct your air conditioning leak, or should you have a unit installed within an attic space, the safest course of action would be to seek assistance from a qualified HVAC technician.
