What is a proper maintenance schedule for an electric-only heatpump?
I plan to have the system checked every year, and I assume that
temperatures, pressures, and amps are measured, but should other
things be done as well, such as clean the coils? And how often
should coils be cleaned?
Is it possible to clean coils too often and cause corrosion? The
Grainger catalog indicates that most coil cleaners are caustic or
acidic, and my concern is that some could become trapped where the
tubes meet the fins. I'm especially worried because other types
of cleaners leave residue even when their labels say otherwise.
BTW I don't plan on doing any of this maintennace myself.
