I can see smoke coming from my heat pump and it’s making a weird noise.
What you are seeing is normal, believe it or not, it is steam not smoke. Ice forms on the outdoor coil because of the low pressure in the coil condensing moisture and consequently freezing it. The unit is designed to initiate a defrost cycle every 30, 60, or 90 minutes. The outdoor fan shuts down, the compressor reverses the flow of refrigerant to run hot gas through the coil to melt the ice. This causes steam to rise from the coil and when the fan comes back on the steam is forced up through the fan section. It will be noisy and alarming the first time you see it but should not be cause for major concern. The process should last a few minutes. If it continues longer than that call for service.
