Understand Why HVAC Systems Freeze

When temperatures plummet in Philadelphia, your HVAC system works overtime to keep your home or business warm. However, extreme cold can lead to freeze-ups, which can cause significant damage and expensive repairs. Understanding why this happens is the first step in prevention. Freeze-ups often occur due to low refrigerant levels, blocked airflow, or issues with the outdoor unit. By addressing these issues early, you can keep your system running smoothly throughout the winter.

Maintain Proper Airflow

One of the simplest yet most effective ways to prevent HVAC freeze-ups is to ensure proper airflow. A clogged air filter or blocked vents can restrict airflow, causing the system to work harder and potentially freeze up. We recommend checking your air filters monthly and replacing them as needed. Additionally, make sure that your vents are open and unobstructed by furniture or other objects to allow for even air distribution.

Keep the Outdoor Unit Clear

Snow and ice accumulation around your outdoor unit can block airflow and lead to freeze-ups. After a snowstorm, it’s essential to clear any snow or ice from the unit and ensure that the area around it is free from debris. You can use a broom or a gentle brush to clear the snow, taking care not to damage the delicate components.

Schedule Regular Maintenance

Preventive maintenance is key to avoiding HVAC issues during the colder months. Having a professional inspect and service your system before the winter season begins can help identify potential problems before they escalate. During a maintenance visit, we’ll check refrigerant levels, inspect the system for any signs of wear and tear, and ensure everything is functioning optimally.

Monitor Refrigerant Levels

Low refrigerant levels can cause your HVAC system to freeze. If you notice that your system isn’t heating as effectively as it should, it may be a sign of a refrigerant issue. Since handling refrigerants requires specialized training and equipment, it’s best to leave this task to the professionals. We can check and replenish refrigerant levels safely and efficiently.
