Common Reasons Why Your AC Unit Is Leaking Water

Is your air conditioner leaking water? When an AC unit starts to malfunction and you find puddles of water inside your home or near the unit, you may be wondering what’s going on. An air conditioner that is leaking water can be a source of frustration for homeowners. Your unit will struggle to keep your home cool enough, especially in the hottest summer months, leaving your family uncomfortable and increasing your utility bills. If your air conditioning unit’s water leak isn’t addressed right away, your AC unit might need more expensive repairs, too.

If you ever encounter a leaking air conditioning unit, you’ll need to act fast. Some repairs can be easily resolved by a handy homeowner, but you may prefer to contact Ahwatukee AC repair to get the job done. This way, you can get your home back to a comfortable temperature and avoid more expensive repair bills later.

How do you know what’s causing a leaking AC unit? Here are some of the most common reasons.

All AC Units Can Leak Water

It’s important to realize first of all that all air conditioners can leak water. This common problem can be avoided with proper maintenance to your unit, but it’s still likely that you’ll have to deal with a leaking AC unit at least once. Although water leakage is a sign of a malfunction, it’s a common problem that can happen with all types of AC units:

Central Air Systems

If your home’s central air system is leaking water, you’ll probably notice that your home’s temperature is uncomfortably irregular or inconsistent. You may find leaks inside or outside of your home.

Mini Splits

Water can drip into your home from a split indoor AC unit. It can be frustrating to continually find puddles of water in your home, which can cause mold to grow inside your flooring. It’s also a fall hazard in your home.

Window Units

If your window AC unit is leaking, you’ll want to contact Apache Junction AC repair right away, because the window itself could be at risk of damage if the unit isn’t repaired. Your unit won’t function optimally and you’ll likely have increased utility bills.

Identifying The Cause of an AC Leak

So you’ve found a puddle of water near your air conditioner. What caused this to happen in the first place? Determining the reason will help you or your AC technician get the problem resolved faster so your home can stay cool and comfortable!

Clogged Drain Line

The evaporator coil on your AC unit cools down the air so that comfortable air can blow throughout your home. The temperature difference between the hot and cold air causes moisture to collect on the coil as the unit operates. Normally, this moisture, called condensate, is removed through the drain line, but when this line fills up with dust and sand, it clogs and malfunctions. Clogs in the drain line mean that excess condensate has nowhere to go and will end up on your floor. A Phoenix AC company can get to the bottom of the problem and remove the clog.

Low Refrigerant

Refrigerant is necessary for an AC unit to produce cool air. When it runs low, your AC unit can longer cool down the hot air. Instead, the evaporator coil will freeze solid, creating ice buildup inside the air conditioning unit. Eventually, it will result in a leak. You’ll be able to identify this problem because you’ll hear a hissing or bubbling noise coming from your AC unit. Contact a Queen Creek AC repair company to get more refrigerant so your unit can start running again!

Dirty Filter

Your AC unit’s filter protects the unit from becoming overwhelmed with sand, dust, and dirt. But once this debris builds up in the filter, your unit will no longer function properly. A dirty filter will block air flow through the evaporator, resulting in a frozen coil. The coil itself can also collect debris, which will also cause it to freeze and prevent it from being able to cool down your home’s air. Routinely replacing your AC filter and cleaning out the unit will help prevent this problem.

Leaking Drain Pan

The drain pan’s job is to gather moisture that collects on your air conditioning unit, but if the pan overflows or breaks, it can leak. Even if the drain line is working properly, a leaking drain pan will result in frustrating leaking around your AC unit.
