Your air conditioning unit is part of the HVAC unit. Most HVAC units have a two part system that allows you to cool your home down with the AC and heat it up with a heater, furnace or boiler. You want to make sure that you have an understanding about your air conditioning unit as the summer heat starts to wave in. The more you understand about the unit and when to worry the more likely it is that you will catch a problem in advance. There are many parts to the air conditioner that could end up being a problem. One of them happens to the coils that are located in the outside part of the house. When the coils are having a problem such as freezing over it is a sign that there is usually a problem elsewhere in the system. You want to be aware of this and be sure that you call out a professional right away. North Country Aire outlines the most common causes of condenser coils freezing over.
Clogged Condensate Drain Line
One of the things that you should know about your AC is that it does produce condensation or moisture. This is the same kind of reaction that your drink has when it is cold and the air around it is warm. The can or cup will start to sweat or condensation will appear. Now when the air conditioning is running it is pulling hot air out of the house and sending back in cooler air. This change in the temperature around the unit is the cause of condensation. Although the moisture is not the problem the drain line that it is intended to move through can be. The line can become jammed up with gunk or debris. It can also get damaged and pressed together so that the moisture has nowhere to go. This then allows the moisture to stay around the coils and that will then cause them to freeze. A professional can clean the lines or make the necessary repairs.
Dirty Air Filters
If you are in your house and look around near the thermostat you will notice a larger vent that is called a register. This particular register is called the return air and is where all the air that is in the house is sucked and circulated through the system. The air is then sent back in the house cooled off. At the location of the return air is a filter that needs to be changed on a regular basis. If it is not, the air is not able to move through freely and that low flow of air will cause the coils to freeze over. You want to make sure that you have your unit serviced regularly which will include replacing the filters to ensure they are changed out.
Broken or Out of Balance AC Condenser Fan Blade
A major component of the unit that helps to keep it running smooth and efficient is the fan and motor. This movement of air around the unit is required and when the fan itself has been damaged or the motor is not working then the air will not cool and the coils can ultimately freeze over. The fan can be replaced or the motor can be fixed but it takes the trained eye of a professional technician to determine that this is in fact the problem.
