Your HVAC unit is covered by your homeowners' insurance to the same extent the rest of your home is covered. Hazards such as fires, vandalism, lightning strikes. Falling trees, and sometimes flooding are all accommodated within the standard homeowners' policies. However, accidental damages and regular wear and tear aren’t.
Fire and Lightning Damage
If your HVAC system is engulfed by fire, your homeowners' insurance will cover the cost of its repair or replacement. Also, if lighting strikes, damaging the electrical components of your unit, your homeowners' insurance policy is most likely to cover its replacement cost.
Falling Trees and Vandalism
When your unit is damaged by a fell tree or branch, you’re protected because homeowner's policies typically cover such damages. Likewise, if the unit is vandalized, you’re also protected since destruction from vandalism is typically covered by the policy. Remember to also file a police report to properly document the crime and damage.
