Wireless or pull new wiring?
I'm wanting to replace a 20 year old central A/C.
Central North Carolina, zip code 27106.
2-story, no zoning, 1500 sqft, 3 ton existing unit (flat coil above a gas furnace)
Efficiency? Whatever the minimum was then for York builder-grade units.
Current quote is for SEER 14 Goodman: SSX140361, Indoor coil CAUF3642C6
I briefly discussed upgrading to a heat pump (w/ the existing furnace as backup) - no formal quote yet.
But I was told I'll need new wiring or wireless controls - and about half the cost of upgrading to a heat pump would be the wireless controls!?
Are wireless controls reliable, or should I pay to pull new wiring?
And from what I've read here, I absolutely do want a variable blower if I choose a heat pump? (anything else I need to know if I go w/ a heat pump instead of just a new coil/outside unit?)
Thanks for any feedback!
I just dont believe pulling new wire is that difficult. Even if the stat needs relocated.
Is there any homeowner benifit to wireless?
One of the best stats on the market, the Honeywell IAQ, only needs three wires. It will do a better job of controlling summer humidity than most all other stats on the market. Just what you need in NC.

blower is in the furnace unless you go all electric and use a blower coil.
as said before use the honeywell iaq for control of system.
No thanks, don't want to replace furnace - will live w/ existing blower.
So using that Honeywell will allow me to control a heat pump with the same wires I'm now using for just a compressor? (thought heat pump required more wires - or a wireless setup)
I'll post again when I get a quote with the heat pump (any recommended features/upgrades I should look for with the Goodman units?)
Thanks for all the quick replies!
[EDIT: I only see 4 wires at my indoor thermostat - assume 2 are power, 2 control?]

You would be assuming wrong.
The IAQ only needs three at the thermostat location.

Don't worry about the wiring, or any of that....if you are having your quotes done by a top notch, reliable contractor, they will take care of all this for you. The Honeywell stat requires 3 wires to function properly. How come non of your quotes were for a heat pump system? This would worry me a little bit as this is one of the best and most efficient systems you can invest in (heat pump and gas furnace). They are extemely popular here in Ohio. Have any of the salesman actually spent the time with you and gone over all of your options? Have they performed the measurements needed to properly size your home and your cooling demands??
I need a new signature.....
