With Mount Spurr currently at a Yellow/Advisory status, residents and business owners in Anchorage are being reminded of the potential impact volcanic activity can have, not just on travel and visibility, but on heating systems and indoor air quality. Even minor ashfall can affect HVAC systems, reduce efficiency, and pose health risks if not properly addressed. Here’s what to know and how Diamond Heating can help keep your home or business protected and running efficiently.
How Volcanic Ash Affects Anchorage Heating Systems
Mount Spurr, located about 80 miles west of Anchorage, is being closely monitored by the Alaska Volcano Observatory. While there’s no eruption imminent, volcanic ash (even in small amounts) can have serious consequences for heating systems and air quality indoors.
- Clogged Filters and Reduced Heating Efficiency
Volcanic ash is highly abrasive and can clog furnace filters, air intakes, and ventilation systems. This can cause HVAC units to work overtime, reduce their lifespan, or shut down altogether.
Tip:
Replace your HVAC filters more frequently during periods of volcanic unrest, especially if you notice reduced airflow or dust buildup.
- Blocked Vents and Safety Concerns
Ash can accumulate around outdoor exhaust vents, which may lead to poor ventilation or backdrafting of combustion gases—a serious hazard.
Tip:
Have your vents inspected and cleared of ash buildup after any advisory or ashfall. Diamond Heating offers professional inspections to ensure your system is safe and operating properly.
Volcanic Ash and Indoor Air Quality in Anchorage Homes and Businesses
- Poor Indoor Air Quality from Ash Infiltration
Fine ash particles can easily enter buildings and circulate through HVAC systems. This can worsen respiratory issues, especially for children, seniors, and individuals with asthma or allergies.
Solutions:
- Use HEPA-grade air filters in your HVAC system.
- Run air purifiers to trap fine particles indoors.
- Avoid running ventilation fans (like stove or bathroom fans) during ashfall unless they’re equipped with filtered intakes.
- Keeping Your Space Safe During Ashfall
Whether you’re a homeowner or operate a commercial space, keeping doors and windows closed and limiting outside airflow is key during an ash event.
Tip:
Stock up on spare filters and consider sealing off non-essential intakes temporarily if ashfall is predicted.
Preparing for Power Outages and Backup Heating in Anchorage
- Backup Heating Options
Volcanic activity can also impact power infrastructure. If the power goes out, homes and businesses without backup heat could face dangerous indoor temperatures.
Solutions:
- Install a backup generator or battery system to keep heating systems running.
- Consider safe secondary heat sources such as pellet stoves or indoor-rated propane heaters.
- Work with Diamond Heating to ensure your home or business has a winter-ready heating plan in place.
