Signs That You Need AC Evaporator Coil Repair

When something’s not right with your AC unit’s evaporator coil, it’s imperative that you get it taken care of as soon as you can. If you let the issue linger, it can end up causing you more stress and costing you more money in the long run. Fortunately, there are typically clear signs that you’ll notice when the evaporator coil needs to be repaired. If you notice one or more of the following red flags, don’t hesitate to give Cougar Heating and Air Conditioning a call.

Fun Fact

Cleaning your coil can saves energy and lower monthly expenses.

Blowing Warm Air – When the evaporator coil isn’t doing its job properly, the air conditioner won’t be able to effectively produce cool air. As a result, you might notice that your AC unit is suddenly blowing air that’s room temperature or warm. When this happens, it’s a clear sign that you should have the system inspected as promptly as possible.

Leaking Refrigerant – Your air conditioner’s evaporator coil contains a coolant called freon, and in some cases, that coolant will start leaking when there’s something wrong with the coil. If you notice that this is happening, it’s important that you shut off the AC unit and let professionals handle the issue.

Leaking Water – In some cases, a malfunctioning evaporator coil will end up with an excessive amount of condensation, which can lead to the coil becoming frozen. Then, when that ice starts to thaw, the resulting water may leak or overflow from the appliance.

Unusual Odors – When an AC unit’s evaporator coil isn’t functioning properly, condensed water may sit on the coil for long periods of time without evaporating. When that happens, mold and bacteria can start to grow, which may result in unpleasant odors coming from the coil.

Coil Cleaning and Repair Services in Spokane, WA FAQs​

The evaporator coil is the coil that is located in your indoor unit. This may be on the inside of your air handler, or it may be, in its case, located adjacent to the gas furnace. The evaporator coil will have two copper lines running to it and some form of drain line leaving it.
The evaporator has one main job when it is operating in cool mode. That is to pull the heat out of the air in your home and push that heat to the outdoor unit, where all of the warmth is released. When the air is drawn into your return duct, it is pushed or pulled by the blower motor across the evaporator coil, which is very cold. As the air passes over it, the heat from the home is transferred into the refrigerant in the coil, and the air is cooled. This process is how your house gets cool air while your outdoor unit blows hot air out the top. The evaporator coil will do the opposite if the system is running in heat mode. You will have to have a heat pump operating in heat mode for this to happen. The refrigerant will be reversed and running in the opposite direction, which means that it will release the heat that it has collected from outside into your home.
The evaporator coil’s most significant issue is poor or inadequate airflow. Airflow may be restricted by multiple different means: 1. Dirty coils can be caused by animal hair, not changing your filter regularly, or not using a filter. 2. Similar issues can cause dirty fan blades, but this is a harder issue to solve as the fan itself will have to be taken out and cleaned away from the unit. 3. Drain blockages are another problem that can have huge effects. If the drain becomes clogged, it can cause the unit to leak, which can damage your electronics or sheetrock, depending on where your indoor unit is located. 4. Frozen coils are generally a result of poor airflow conditions. This means that fixing frozen coils could be as easy as replacing a filter or cleaning the evaporator coil
Typically, the lifespan of an AC evaporator coil is around 20 years. However, they tend to start declining after around 10 to 15 years, so it’s usually advisable to replace them somewhere in that timeframe. When an evaporator coil is older than that, it will start to gradually lose its efficiency and effectiveness. That said, there are some cases in which a coil should be replaced sooner than that. For example, if your cooling system’s evaporator coil has extensive damage or frequently needs to be repaired, it may be more financially prudent to have it replaced. Otherwise, you may end up spending more on the repairs than it would cost to simply invest in a new coil.
Depending on what has happened to the coil, it is possible to repair one. There are times when vibrations will cause copper lines to rub together, creating a hole, or some outside force has damaged a part of the coil. These are ideal situations to try and repair a coil. If your coil has suffered from rust and the copper has deteriorated to the point that a hole has developed, then your coil will not be able to be replaced. To braze correctly, you need clean metal, and if the copper is deteriorating to the point of failure, it is likely going to be far too thin to apply enough heat to braze.
