Heat Pump Icing Up in Florida
Ice forms on the evaporator coil and does not clear between cycles. This page covers how we diagnose and repair it on heat pumps in Florida.
This fault is normally treated as priority work because the plant is still running but is damaging itself or wasting energy while it does.
Established residential suburb with high-rise flats on centralised hot water systems. Where a site runs on borehole water, hardness and iron content shorten service intervals considerably and are worth testing before setting a maintenance plan.
