Should there be water around my heat pump? It hasn't rained.

Water around the heat pump is normal. In the heating mode, the heat pump coil is colder than the air around it and frost may form on the coil. When the unit is operating normally, it automatically defrosts, and the water lands on the ground around the unit. In very cold weather, this water may freeze and build up ice below the unit.

I see "smoke" coming from my neighbor's heat pump. Should I call the fire department?

That is probably normal. You are most likely seeing the mist from the water evaporating on the coil. It's the same as seeing your breath on a cold day.

Should there be ice on my heat pump?

As noted above, there may be frost on the unit. However, unless there has been an ice storm or heavy snowfall, the frost should melt during the defrost cycle. Ice is a different story, though. If there is an ice buildup that does not dissipate after 24 hours, this could be trouble. As the ice continues to build and the temperature drops below 25 degrees, the ice may expand and could crush the coils.

What should I do if the ice stays on the unit?

If the ice stays on the unit, it is best to turn off the heat pump and call for service. Most heat pump thermostats have an "Emergency Heat" switch setting. This turns off the heat pump and allows the resistance heater to operate. With this switch setting, it is more expensive to heat your home, so it is important to have your system repaired in a reasonable amount of time.
