Although there may be hundreds of factors why your city home’s central air conditioner may need to be looked at by a certified contractor, there are a few reasons that are fairly common like Ice on the coils of your air conditioner. Maintaining a clean and functional cooling system means enjoying the perfect indoor temperature at any time of the year. Issues can lead to poor cooling performance, higher monthly utility bills, and an increase in your system’s long term risk for a major breakdown. If you see ice on your air conditioner’s evaporator coils, it can be easy to think that this is a sign that your air conditioner is performing well. Ice formation is actually a sign of poor cooling efficiency that should be addressed immediately with the help of an AC repair professional to restore your air conditioner’s ability to cool your home efficiency using less energy.
Ice Formation Due to Airflow Problems
The most common cause of ice formation is poor airflow through the system. Check your AC filter if it has been left in place too long, it can become clogged with dirt and dust. A clogged filter acts much more like a solid barrier then a screen, making it harder for your air conditioner to draw in air for cooling and causes the coils to freeze up. The evaporator coil (tubes forming the A-shaped part of the inside unit) has cold refrigerant flowing through it and a blower pulls in air from your home and over that coil, cooling the air. When there’s little to no air flowing over the cold evaporator coil, it quickly frosts over because there’s less heat to absorb. When it’s frosted over, air can’t easily flow through the coils (it’s a solid block of ice now), reducing airflow to your home. This causes added strain on the motor and can cause your system to wear out prematurely. Call a professional for AC repair, the entire system will likely need a complete cleaning and tune up to restore efficient cooling without ice formation.
Ice Formation Due to Low Coolant Levels
When your AC system is low on refrigerant, pressure drops causing the evaporator coil to get abnormally cold. So when returning air hits the coil, humidity/moisture from the air beads ups on the coil and quickly freezes. This continues until the evaporator coil is frozen. If you’re low on refrigerant you also have a refrigerant leak. That means you’ll need a professional to find the leak and fix it before adding more refrigerant. Worst case scenario: The leak can’t be fixed and one of the refrigerant coils needs replacing. This is an expensive replacement. So if your AC is 15+ years old, you should consider replacing it. Only a professional can check for coolant leaks, repair damaged lines and recharge your system with the right level of refrigerant to eliminate ice formation and restore cooling function. Coolant leaks release refrigerant into the atmosphere that can be damaging to the environment so it is important to schedule repair promptly.
