Tips for Handling HVAC Issues During a Blizzard
Stay Warm When the Snow Piles Up
Blizzards bring more than just picturesque views; they present a significant challenge to your home's heating system. When temperatures plummet and snow drifts rise, your HVAC unit works overtime to maintain a comfortable indoor climate.
Understanding how to manage your system during a winter storm can prevent costly repairs and keep your family safe. If you find yourself in over your head, remember that you can find reliable professionals through the HVACDatabase.com directory.
Clear Your Exterior Vents Immediately
The most common cause of furnace failure during a blizzard is a blocked exhaust vent. High-efficiency furnaces typically vent through PVC pipes on the side of your house rather than through the chimney.
If snow accumulates and blocks these pipes, your system will shut down automatically as a safety precaution. This prevents carbon monoxide from backing up into your living space.
- Check your vents every few hours during heavy snowfall.
- Clear a path at least three feet around the intake and exhaust pipes.
- Avoid using a metal shovel near the pipes to prevent cracking the plastic.
Address Potential Power Outages
Blizzards often lead to grid failures. If your power goes out, your furnace will stop running, even if it uses gas or propane, because the blower motor and electronic ignition require electricity.
If you have a backup generator, ensure it is rated for the sensitive electronics in modern HVAC systems. Many homeowners choose to use a portable heater during a furnace emergency, but safety is paramount.
Keep space heaters away from curtains and never leave them unattended. If the power remains out for an extended period, you may need to drain your pipes to prevent freezing and bursting.
Monitor for Unusual Smells
During a storm, you are likely spending all your time indoors with the windows sealed tight. This makes it easier to notice unusual odors coming from your vents.
If you detect a rotten egg scent, it is critical to act fast. You should learn why your furnace has a strong gas smell and evacuate the premises if the scent is overwhelming. Contact your utility company and an emergency technician immediately.
Insulate and Conserve Heat
When the wind is howling at 50 miles per hour, your home loses heat through every microscopic crack. You can take pressure off your HVAC system by manually conserving energy.
Close Off Unused Rooms
If you have guest rooms or storage areas that aren't being used, close the doors. This concentrates the heat in the areas where you are actually spending time.
Use Natural Sunlight
During the day, open your curtains on the side of the house facing the sun. Even in sub-zero temperatures, solar gain can provide a slight boost to your indoor temperature. Close them as soon as the sun sets to add a layer of insulation.
Prepare Before the Storm Hits
The best way to handle a blizzard is to ensure your system is ready before the clouds gather. Many homeowners realize that why fall hvac maintenance prevents winter emergencies is because a technician can spot worn-out ignitors or cracked heat exchangers before they fail in the cold.
Check your system's efficiency levels before the season starts. Understanding AFUE ratings explained for furnaces can help you decide if your current unit is robust enough to handle extreme northern winters.
When to Call a Professional
Do not attempt to repair internal furnace components during a storm. If your system won't start after you've cleared the vents and checked the breaker, it's time for expert help. Using a resource like HVACDatabase.com allows you to find trusted HVAC professionals in your local area quickly.
Knowing how to find 24-hour emergency hvac services is vital during a blizzard when many companies are backlogged with calls. Be prepared for potentially higher rates due to the hazardous driving conditions for technicians.
Watch for Internal Leaks
Extreme cold can cause components to contract and seals to fail. While less common than in summer, you should still know how to handle an hvac refrigerant leak emergency if you notice pooling liquid or hissing sounds near your indoor or outdoor units.
Keep a list of emergency numbers on your refrigerator so you aren't scrambling if your internet connection goes down during the blizzard. Stay safe, stay warm, and let the professionals handle the heavy lifting.
