Heat pumps function differently than a traditional heating system or window air conditioner. Rain and snow can lead to certain behaviors in the unit that may cause alarm in first-time heat pump users. Most homeowners tend to call for emergency HVAC service as soon as they notice something strange with their heat pump; however, by knowing which things are normal and which aren’t, you can save yourself a lot of trouble and panic.
One example of strange heat pump behavior is when the outdoor unit appears to be generating smoke. Users often assume that the smoke is coming from a malfunctioning fan motor because the fans usually stop working when this happens, but fortunately the truth is actually a bit less concerning. Here our experts at J&M explain why a smoking heat pump may not be a problem.
