poor hvac performance
|
|
|
| I'm hoping someone can help me understand what the problem with my
heating and air conditioning unit might be.
It is a Goodman 3 1/2 ton "split system" heat pump, installed about 4
years ago. The compressor is about 40 feet from the air handler.
When the unit comes on, especially to provide heat, the temperature of
the air coming out of most of the vents never surpasses 77. Only one
vent, situated directly above the air handler, actually creates really
hot air, reaching 90 degrees. With the others, it first comes out
colder (which I understand), then rises a about a degree each minute,
but typically levels off at 74-75. Emergency mode does not seem to
make any difference. On cold days, the unit runs virtually non-stop,
24 hours a day.
The installers told me that this was normal for most heating/air units
of this type. At first I accepted this. But now, I'm questioning it.

doing, and get rid of that hack.

That's most of your problem there. also, you need to change the
thermostat.

This is a big part of the problem... cheapest units that are typically sold
to *anyone* regardless of their qualifications or abilities.

You need to call your local *competent*, licensed, insured, professionally
trained, HVAC technician (not necessarely a Goodman dealer either) to
diagnose and correct the problems with the system.

It took 4 years to figure out that your low bid installers are hacks and
idiots??

| Rees,
Sounds like "venturi effect".

Simple fix.
Attach a refrigerant cylinder and charge it till it wont take anymore.
Next, replace the thermostat. Its almost always the thermostat.
Next, install a ductbooster in each suppy run except the one that is
already reaching 90 degrees.
Lastly, install ductboosters in your return duct in reverse.
Now see how it does.

Sounds really low on freon. Also, your thermostat is probably bad. Get a
digital one.

Oh. . . OK. Lessee, that'll be $4500. Can I get alt.hvac to chip in?
About $500 from each of yas would really help.

| $4500 sounds about right for another 3-1/2 ton Goodman.

Yeah, hold your breath and we all will be right out to bring over the
cash. If you start turning blue, before we get there, just keep
clicking your ruby slippers together and say, "there's no place like
home...there's no place like home"
