Heat Pump vs Compressor

Posted by Bob Simon on October 17, 2006, 3:32 pm

I need to replace my 2.5 ton air handler unit because the condensate
pan is rusted out and water is dripping from the attic. The 2 ton
compressor hasn't lost any freon in the past year and is working fine,
but I'm thinking about replacing it at the same time because both
units were installed in 1985. If I do, should I replace the existing
unmatched system with a 2.5 ton compressor and 2.5 ton evaporator?

It was suggested that I consider replacing the existing heat pump with
a regular compressor and use resistance heat from the 10 KW unit in
the air handler. I'm certainly no expert but I thought that here in
New Orleans (where the average winter low temperature is 46 degrees)
is an idea place to use a heat pump. I would appreciate some advice
on any of these issues.

I would replace it with whatever my competent licensed professionally
trained HVAC tech thought I should replace it with. Id be asking for a
load calculation of my home to make sure that my costly investment
turns out to give me a decent payback over the life of the equipment.
Personally, Id be interested in a heat pump system if you have no
fossil fuel available.

1. Get aheat load/loss calc done.
2. Ditch the retard who suggested electric heat strips.
3. Go with the heat pump.

I"m in Phx so our winters are pretty mild.. I switched from heat pump
to just electric strips and my winter bill stayed about the same and
the heating capability is actually a little better.
