Snowing in Hampton Roads - Frozen Condensers
Last week, we responded to a service call in Hickory, where an HVAC unit suffered from an unusual issue in Hampton Roads Virginia. Nestled directly beneath a roof valley without gutters, the unit was initially pelted with water from melted snow. Overnight, the temperatures dropped, freezing the water and causing the fan to ice over and stick. Interestingly, the system itself was in good condition—there was no ice on the coils, which indicated that the main components were still functioning correctly.
What to Do If Your HVAC Unit Freezes
If you find your HVAC unit frozen due to similar circumstances or due to heavy snowfall, here’s what you can do:
Gently Remove the Ice: Begin by gently running lukewarm water over the ice. It’s crucial not to use hot water or splash it abruptly, as sudden temperature changes can damage the metal. As the ice begins to melt, carefully remove the chunks to prevent them from refreezing onto the unit.
Assess the Situation: These steps may help your unit temporarily recover, but they do not address potential long-term damage from falling ice, water intrusion in controls, or general water damage. Always monitor the unit after such an event.
Prevent Future Incidents: To prevent such occurrences, consider installing gutter systems where needed, and ensure your unit is not positioned directly beneath areas prone to snow and ice accumulation. Additionally, maintain a clear area around your HVAC to avoid airflow blockages and potential freezing.
Why Maintenance is Crucial
Regular maintenance is your best defense against winter-related HVAC issues. Here are a few preventive measures:
Regular Inspections: Have your ducts and overall system checked to avoid restricted airflow, which can exacerbate freezing issues.
Proper Filtration: Use the correct filters for your system and change them regularly to maintain optimal airflow and system health.
Routine Check-ups: Regular professional servicing helps identify and fix potential fail points like malfunctioning parts that could lead to moisture buildup and freezing.
