Do you know the potential impact snow and ice can have on your HVAC system?
How Winter Conditions Affect Your HVAC Unit
There are several ways that snow and ice can damage your home heating and cooling systems:
- Snow and Ice Build Up: When snow and ice surround your unit, this could cause your system to freeze and trigger an emergency shutdown. As a result, the heat to your home will be cut-off, and your waterpipes could be in trouble.
- Blocking the Exhaust: Too much snow could block your furnace exhaust. This may prevent your unit from working, or even worse, allow harmful chemicals like carbon monoxide to come into your home. Most furnaces will have a safety switch to shut down your unit if it becomes blocked.
- Damage to Your Outdoor Unit: Icicles that accumulate above your outdoor HVAC unit may fall and damage your system. This damage can be fairly extensive and lead to expensive replacements.
- Ventilation Blockage and Leakage: Too much snow and ice build-up can block ventilation, preventing your system from working correctly. Additionally, this build-up can cause your pipes to leak and not work correctly.
- Corrosion and Rust Build-Up: Melting snow can cause water to leak into your system, freeze again, and expand — leading to corrosion and rust build-up throughout your HVAC unit.
Protecting Your HVAC System
Ultimately, the winter season makes your HVAC unit work twice as hard. Airflow is often limited, which could result in your unit short circuiting or burning out faster than you expected. Here are our top tips for protecting your HVAC system this season and prolonging its lifespan:
- Clear Away Debris: Shovel away snow build-up as it accumulates. Clean and inspect your gutters often to make sure they aren’t dripping onto your unit. Melt away ice from your unit using warm water.
- Check Your Filters Regularly: A clogged filter will restrict airflow and could result in an inefficient HVAC unit that doesn’t heat up to your desired temperature. Airflow matters, so change your filter early and often. Even if you’ve changed it recently, if you have airflow issues, you’ll quickly have furnace issues.
- Hire an HVAC Technician: Getting your unit maintained regularly can prevent costly damage in the dead of winter.
Pro Tip: Also cover your water pipes if they are exposed to extremely cold temperatures.
