Replace inside unit as well?

[boaterbob]

Now that you all determined that I have an incorrect t-stat for my heat pump, I have another question.

If I toss my 3 yr old Tappan 10 SEER < very noisy > heat pump and replace it with, say a Lennox XP19 heat pump <suppose to be very quiet>, do I need to also replace my in-the-attic air handler (also 3 yrs old).

Do they need to open the walls or roof of the house to replace an in-the-attic air handler - would be expensive!?!

Thanks
Robert

yes you should replace the indoor unit also.. hopefully they don't need to cut a hole.. there should be attic access so you can change filters and provide maitenence to the indoor unit.. the new one may fit through this.

What gets 'replaced' - just the coil and blower motor? Or do they need to replace all the metal housing as well?

Replace both sections as a matched set, especially with a heat pump.
Re-using an old cabinet is not worth the trouble, even if it were the same physical size, which it NEVER is.
The ductwork will need to be adapted to fit your new indoor section.

Ok - here's where I stand at the moment:

Replace the 3 ton Tappan 10 SEER with a Lennox 16 SEER, all the necessary air handler rework, move the condenser unit approx 8 ft (away from the bed room window) by extending the wiring/tubing along the outside of the house. $5875, tax included.

You also need to call and contractor and second now pricing allows on this site

While I see the truth of the pro's statement you need a new air handler for that heat pump, I wonder if... that is because the high end heat pump requires variable speed air handler because it probably is two stage?

The coil near the air handler would need to be matched with the heat pump, which I see as a separate matter. Of course a change would be almost certain, as the original heat pump sounds to me like a builder's grade cheapie. I should always remind you that I am not a pro but a homeowner, and take that into account when weighing what I say.

Best of luck -- Pstu

Both. Putting a standard efficiency Nordyne AH with anybody's 13 SEER is a mistake. And the XP19 most certainly needs a VS blower.

Robert,
bite the bullet and put in a match system. It should make your life much simpler as far as heating and air problems.
You want it to be dependable correct? Just go ahead.
