How To Inspect An Ac Drain Pan
As warm air passes over the evaporator coils in your AC, water droplets form and drip into the condensate pan located beneath the evaporator coils. This condensate then flows out through the condensate drain line. However, problems can arise when the drain pan or drain line is clogged or damaged. Your AC may turn itself off, or your property may suffer water damage as condensation accumulates underneath the AC. To prevent these problems, Gilmore Heating, Air and Plumbing, the best HVAC company in Sacramento, recommends that you inspect the AC drain pan frequently, as explained below.
Preventative Ac Maintenance Is The Key
The best way to protect your air conditioners drip pan from overflowing is by scheduling annual AC maintenance with a knowledgeable technician. Preventative system maintenance helps you identify problems that can lead to an overflowing drip pan early and avoid system leaks altogether.

Why Does The Horizontal Application Have A Second Drain Pan
For attic furnaces, there is a second condensate drain pan. This is an added layer of protection from water damage.
In most HVAC systems, the entire central air system is lying on its side. In the event of condensate drain pan failure, water does not drip in one general location. Instead, water drips from the entire central air system. Additionally, overflow of water results in damage to the ceiling, drywall, and wood. To protect the home from water damage, a secondary condensate drain pan is fitted beneath the entire appliance. This is similar to placing a pan beneath the car during an oil change. This added barrier protects the floor from stains and other damages.
This secondary condensate drain pan also has its own drain line. It is connected directly from the pan to an external location, usually traveling out the window. It is highly visible. Homeowners should notice when the central air system reverts to this water removal method. It means that the standard method has been compromised. An HVAC specialist should be called in order to make timely repairs.

Cracked Condensate Drain Pan
A cracked pan will leak water indoors. The condensate drain pan may crack due to a number of factors, including accidental falls, chips in the material, heat damage, and general wear and tear. Depending on the severity of the damage, water will leak out of the cracks and into the room, damaging floors, walls, and furniture in the process.
A cracked pan can damage your unit as water drips through the air system. A cracked pan in your central air system can leak water through the air ducts, causing water damage and mold growth. Replace the pan as soon as you notice the crack to prevent further damages to your home.
What If I Have A Clogged Ac Drain Line
If you suspect a clogged drain line, you should test it. Try to pour a gallon of water down the condenser drain inside the access panel. If the water doesnt immediately travel through the pipe and out of your home, you have a clogged drain.
You can contact a professional technician or snake the drain to unclog the condensate drain. To prevent future clogging, pour 1/4 cup of distilled vinegar down the condenser drain about once per month.
STAT: According to a 2020 US EIA survey, 23% of Americans use air conditioning systems between 5 and 9 years old.
F.A.Q.S
How do I inspect the condensate drain line?
The condensate drain pipe is a white T-shaped PVC pipe that leads to the outdoors. You can find your drain line near the indoor air handler in a utility closet or attic. Look for cracks, a water leak, or signs of damage along the entire drain line leading from the indoor unit to the outdoor unit.
Is vinegar good for an AC drain line?
Over time, mold, algae, and bacteria growth can cause a condensate drainage issue or a wholly clogged condensate drain pipe. Many experts recommend white vinegar for your drain line cleaning. You can pour 1/4 cup of vinegar down the condensate drain every couple of months, especially during the strenuous summer season.

Why Does The Ac Drain Pan Fill Up All The Time
A clogged drainpipe is one of the common causes for water to stagnate on your drainpipe
The air flowing across loses its humidity and cools down as it passes over the evaporator coils inside the AC unit. The humidity gets left behind as condensation on your AC evaporator coils. The condensation goes through the systems drain line, drips into the drain, and then exits the system.
Dirt and dust also get left behind on your evaporator coil. That indicates that water is not the only thing causing system problems. The dust and dirt come from the air blowing across the coils.
The dust and dirt move down the drainpipe and can result in a clog.
Another issue that can cause clogged water is when the air conditioner was installed incorrectly and has the wrong angle alignments. To avoid this problem, you should have your system correctly installed by a company that has trained and qualified technicians.
The systems drain outlets should be located on the lower side at all times so that the water can flow towards it easily. When the outlet is on the opposite side, water always stagnates rather than draining.
A frozen evaporator coil can cause traces of moisture inside the drainpipe. This results in water dripping into the drain pan. There is a very high chance that the evaporator coil will freeze if refrigerant levels are low. Low levels of refrigerant are a sign that the AC system has a refrigerant leak. Our teams technicians can identify leaks quickly and repair your system.
Reasons Your A/c Drip Pan Has Accumulated Water
Evaporator Coil Freezes
A frozen evaporator coil can cause dripping water that will result in moisture in your drip pan. If the refrigerant levels happen to be low, the evaporator coil will probably freeze. If you are experiencing low refrigerant levels, this usually signals a refrigerant leak somewhere in the system.
Our certified technicians at Apollo can resolve this issue for you by identifying leaks and repairing your system. After there is no longer a leak, your refrigerant can be recharged.
Drain Pipe is Clogged
The most common cause of standing water in the drip pan is a clogged drain pipe. As the air circulates over the evaporator coils in your air conditioner, it cools down and loses a portion of its humidity. That humidity is left behind in the form of condensation on the coils. The condensation drips off and into the condensate drip pan and leaves the system through the drain line.
In addition to water being left on the evaporator coil, dust and dirt can be found there also due to the air that blows over these coils. A clog occurs when the dirt drips off in the water and it moves down the drain line.
A/C System was not Properly Installed
If your home A/C unit was installed incorrectly, the drip pan could be angled in the wrong direction. The outlet for the drain must be on the lower side of the pan so water can flow toward it. However, if the outlet is instead on the opposite side of the pan, water will accumulate before having the chance to drain.

Clean The Condensate Drain Line
Gilmore HVAC experts recommend that you clean the condensate drain line regularly in order to prevent dirt and debris from building up inside it.
Use a stiff brush to gently clean inside the drain line and remove any debris inside. You can then pour a cup of vinegar down the drain line so that any microbial growths can be killed before clogs develop.
In the summer, pour bleach down the condensate drain line as a way of keeping it clean. Gilmore Heating, Air and Plumbing only recommends using bleach during the summer because the constant use of the AC will generate ample quantities of condensate to wash out the bleach before it damages the drain line.

Is An Ac Drain Pan Replacement Necessary
A drain pan is one of the things you should monitor since they dont last forever and are prone to issues. For example, if your AC has two, you should periodically check if there is excess water collecting in your secondary pan. This is usually a sign that the primary drain pan is not working properly.
Excess water, in general, usually points to a bigger problem. There might be a clog between the drain pan and the area that drains liquid back into the main system, or the pan itself could be slightly tilted to one side.
In any case, you should never let the water sit too long in your drip pan. It could lead to mold, and even worse, it could attract insects .
Take a look at your drip pan and if you see any corrosion, youre due for an AC drain pan replacement. A corroded pan might develop cracks which can then cause significant water damage.

Should My Exterior Ac Drain Pipe Be Dripping Water
The condensate line should drain to the outdoors and during humid weather you should see plenty of water dripping from it. If you see dripping water from any part of the condenser, you need to replace it with a new one. You can do this by removing the old one and placing it in a bucket of warm water.
Let it soak for a few minutes, then rinse it out with water and let it dry. The first is to use a vacuum cleaner to suck up the water, but this will only work if the vacuum hose is connected to a hose that has a suction cup on the end.
It is also possible to put a piece of duct tape over the hose to prevent it from sucking up any more water than it needs to. Another option is a water softener. These can be purchased at your local hardware store or online.

What’s in the article?
Air conditioners are cold – coils that handle refrigerant can drop its temperature below freezing, which also causes condensate to form around the unit as water vapor in the air cools to its liquid state.
The reason your air conditioning unit does not leak water indoors as it causes condensation is thanks to the drain pipe, and the drain pan which collects the dripping water from your unit. In this article, we’ll see why drain pans are essential parts of air conditioners.

Always Evaluate The Current Situation Before Making A Final Decision
Even when a drain pan is refurbished quickly, it still takes more than a day to get the job done because the coating needs to properly cure. A replacement can be installed in a short amount of time, which can be handy if you need to replace the drain pan in the middle of summer, when the temperature in your home or business could get very high. If you can live with the A/C not being used for a day or two, a refurbishment might be the way to go. If the floor beneath the A/C is getting damaged, especially if the problem just popped up, it may be a good idea to just go with a replacement.
Always Take Into Account The Hvac Unit Age
The older your A/C is, the more likely it is that finding a replacement will be difficult. Having an older drain pan refurbished may be your best bet with a system more than 15 years old. On the other hand, if your system is relatively new, you should not have a problem finding a replacement.
Most of the time, replacing a residential drain pan is the right course of action. For older A/C models, or for commercial grade units, you may find it more cost effective to have your drain pan refurbished. Either way, keeping a defective drain pan in place will lead to a lot of problems underneath your flooring. Even in an area like a basement, excess water can facilitate mold growth, which can be very dangerous.
