Why Do Air Conditioners Freeze Up?
An AC unit that freezes up is an all too common issue for many homeowners. A frozen air conditioner is especially frustrating in the middle of summer. Sometimes you can follow a few simple tips to take care of the problem yourself, or you may need to reach out to an HVAC company to further investigate the problem. Here are a few of the most common reasons why air conditioners freeze up.
1. Dirty Air Filter
Most people make the mistake of not replacing their air filters on a regular basis. Over time, an air filter will get dirty and cause additional strain on your AC system. All of this extra dust, dirt, and pollen will restrict airflow and cause your system to freeze. The best way to avoid this situation is to change out your air filter every couple of months. You may need to consider replacing your air filter more often if you have pets in your house, children, or if you have a household member who smokes.
2. Refrigerant Leak
A refrigerant leak can cause your air conditioner to eventually freeze up. You may also hear a hissing noise or notice that your AC system is blowing hot air if you have a refrigerant leak. Getting an annual inspection for your HVAC system is the best way to stay proactive. A professional technician can identify any problems and make repairs before the problems get much worse.
3. Obstructed Airflow
An air conditioner can freeze due to obstructed airflow. Vents and registers that are obstructed will cause your system to work much harder than it’s supposed to. Poorly installed ductwork can also create airflow issues in your home. Contacting an HVAC professional is a great way to identify the source of the problem. Professional technicians will keep your air conditioner working at an optimal level.
