[M2inOR]

In Oregon, I had a large home with 2 heat pumps. They had natural gas heat as backup when temperatures were below 35°.

Never a problem for 40 years, unless there was a power failure. With no power, the HVAC system blowers won't blow. We did have a wood burning fireplace for heat, and lots of warm clothing and blankets.

Upgraded the heat pumps and natural gas furnaces every 12-15 years.

No complaints.

One time we had a power failure that lasted almost a week due to an ice storm. Once power was restored, we did purchase an emergency gas generator. Best purchase we ever made as we never had a power failure of more than a few hours. Never had to fire up the generator except for maintenance. We could tolerate a few hours of no power.

Very happy with our heat pump HVAC system in our Marsh Bend home.
