Posted on in Blog
As summer approaches in Longview, Texas, it seems to get a little bit hotter every day. That's why it's crucial to make sure that your AC unit is in top operating condition. This is often easier said than done. After all, you demand a lot from your AC over the course of the hottest months of the year. It's no secret that a leaky AC can be a nightmare, especially when the temperature is building outside. But what exactly causes a leaking air conditioner? This article takes a look at some of the most common reasons your AC is leaking. Keep reading to discover insight into why your house isn't staying cool this summer.

The Drain Pan Is Overflowing

Let's start with something simple. After all, when your AC is leaking, the problem might be nothing more than your drain pan overflowing. When this happens, turn off the unit and use a wet-dry vac to remove the water from the overflow pan. This should take care of the problem. It's also a good idea to inspect the overflow pan for cracks because that can also cause leaks.

The Evaporator Coils Are Frozen

Another common cause of leaky air conditioners in Longview is when the evaporator coils freeze. This often happens when the air filter gets dirty because air cannot pass through; thus, the coils tend to freeze up. This is one of the reasons why it's so important to replace your air filter every four to six weeks.

The Temperature Is Too to Run the AC

You should never run your AC when it's below 60 degrees outside. Why? Because when it's cold out, the evaporator coils can ice over. When this happens, the AC might begin to leak.

The Condensate Line is Clogged

The next common reason for a leaky air conditioner is when the drain line is clogged. This can happen for several reasons. Fortunately, you can fix this yourself with the right tools and a wet-dry vac. But if you don't feel comfortable with this DIY task, go ahead and call a trained AC professional.

The Refrigerant Level is Low

The problem could also be low refrigerant causing the AC coils to freeze. This is another situation where the best strategy is to schedule an appointment with a local AC technician.

The Air Filter Needs to Be Replaced

The cheapest and simplest way to keep your AC unit running smoothly is to make sure it has a clean air filter at all times. As mentioned earlier, a dirty air filter can cause the evaporator coils to freeze, among other things. Fortunately, air filters can be purchased at any hardware store for a relatively low price and are easy to replace.
