R & R Heating | Local HVAC Repair in Oak Lawn, IL

First, turn your system off to prevent further damage. Check if your air filter is clogged, as this is a common cause of freezing by restricting airflow. Then, call R & R Heating. Our technicians will safely thaw the system, diagnose the root cause—whether it's low refrigerant, a dirty filter, or a blower issue—and perform the necessary repair to prevent a recurrence.

For most Oak Lawn homes, we recommend checking your filter monthly and replacing it every 1-3 months. Homes with pets, allergies, or higher dust levels may need more frequent changes. A clean filter is crucial for preventing restricted airflow, which strains your system, reduces efficiency, and can even lead to frozen coils. A clogged filter is a key part of your system's performance, which can cause costly repairs. We're here to help. Schedule a maintenance visit today.
