Heat Pump Question


Hello,

I had a Nordyne heat pump, model JT4BD-024K, installed last year in Nashville. The heat is now on and the thing produces quite a bit of water outside around the base of the unit. Is this normal? The unit is also quite loud when it starts and I wonder if this is normal? I've called the company that installed the unit but get no response and I think they are no longer in business. I hope I haven't been fleeced.

Many Thanks,
Russell

Yes, water is normal. Many times they'll turn into a complete block of ice and then go into defrost mode to clear that ice. When a heat pump is in defrost mode your secondary heat will engage.

In a/c mode you produce water in the inside unit, the evaporator coil. You have a drain leading either into plumbing or outside from that unit. On a heat pump the refrigerant process is reversed, now the water is being removed from the air outside.

The water should just be the melting of the frost off of the outdoor coil during a defrost cycle and is totally normal. The units have drain holes in the base pan for this purpose.

Noisy is relative, but if there is not a "sound jacket" (looks like a special pre-formed blanket) on the compressor (you can see the compressor directly) then this can often be added and will quiet the unit down somewhat.

Thanks for the reply, Done That. But it's not that cold. It's in the forties.

I will look into a jacket to help with the noise.
