What to Do If Your AC Unit Freezes Up. Experiencing a frozen air conditioner in the heat of a Las Vegas summer can be both uncomfortable and alarming. At Active Plumbing & Air, a family-owned business with over 30 years of experience and a 4.9-star rating from 819 Google reviews, we understand the urgency of such situations. Here’s a comprehensive guide on how to handle a frozen AC unit and prevent future occurrences.
Understanding Why AC Units Freeze
Several factors can cause your air conditioning system to freeze:
• Insufficient Airflow: Dirty air filters or blocked vents can restrict airflow, leading to ice formation on the evaporator coils.
• Low Refrigerant Levels: Leaks or inadequate refrigerant can cause the coils to become too cold, resulting in freezing.
• Mechanical Issues: Malfunctioning components like blower fans can impede proper operation and contribute to freezing.
Steps to Take When Your AC Freezes
1. Turn Off the AC: Immediately switch off your air conditioner to prevent further damage.
2. Switch to Fan Mode: Set your thermostat to fan-only mode to help thaw the ice on the coils.
3. Check and Replace Air Filters: Ensure that air filters are clean and replace them if necessary to promote proper airflow.
4. Inspect Vents and Ductwork: Make sure that all vents are unblocked and that ductwork is intact to facilitate adequate air circulation.
5. Seek Professional Assistance: If the problem persists, contact a certified HVAC technician to diagnose and resolve the issue.
Preventative Measures
Regular maintenance is key to preventing AC freeze-ups:
• Schedule Routine Inspections: Regular check-ups can identify and address potential issues before they escalate.
• Maintain Clean Filters: Regularly replacing air filters ensures unobstructed airflow and efficient system performance.
• Monitor Refrigerant Levels: Ensuring correct refrigerant levels can prevent the coils from becoming excessively cold.
