Winter weather can be hard on your HVAC system, especially during snow and ice storms. Without proper care, these conditions can affect its performance and even cause damage. Here are some tips to ensure your HVAC system keeps running smoothly when winter brings freezing temperatures, heavy snow, and ice.
1. Keep Outdoor Units Clear
Snow and ice can block airflow to your HVAC system, causing it to work harder or shut down.
- Clear snow regularly: After a storm, gently remove snow from around your outdoor unit with a broom or your hands (never a shovel).
- Remove ice build-up: If ice forms on the unit, turn it off and carefully melt the ice using warm (not boiling) water.
2. Check Your Heat Pump
Heat pumps are designed to work in cold weather, but ice buildup can hinder their efficiency.
- Allow defrost cycles: Heat pumps have a defrost setting to melt ice. Make sure the area around the unit is clear so it can complete this process.
- Monitor performance: If your heat pump isn’t defrosting properly or ice keeps building up, call a professional for inspection.
3. Prevent Blocked Vents and Exhaust Pipes
Snow can block exhaust pipes or intake vents, leading to dangerous carbon monoxide buildup or system shutdowns.
- Locate pipes and vents: Know where these are on your system, especially for high-efficiency furnaces.
- Check them after snowstorms: Regularly clear any snow or ice to ensure they remain unobstructed.
4. Check Thermostat Settings
Maintain a reasonable temperature on your thermostat to keep your HVAC system running efficiently.
- Consistent settings: Set your thermostat to a consistent, reasonable temperature.
- Avoid making frequent adjustments: Drastic changes increase stress on your HVAC system.
5. Change Air Filters Frequently
In cold weather, your HVAC system works overtime, and dirty filters can reduce its efficiency.
- Inspect filters regularly: Winter weather often leads to increased dust and debris in the air. Replace filters as needed to maintain optimal airflow.
- Maintain optimal humidity levels indoors: Maintaining proper humidity (30%-50%) reduces dust and allergens in the air, easing the load on your filters. A humidifier helps particles settle, improving filtration.
6. Schedule Routine Maintenance
Preventive care is crucial to keep your system functioning during harsh winter conditions.
- Inspect the system before winter hits: A professional technician can identify potential issues early.
- Schedule mid-winter maintenance: If snow and ice have been heavy, it’s worth checking the system for hidden damage or inefficiencies.
