So now we are investigating the best alternaive for heat/cooling and are considering a heat pump. My wofe wants to do away with oil heat - even as a backup - but I'm not so sure.

We have talked to contractors who have proposed:
1.) a Goodman 2.5 ton 13 SEER (I think this is an R-22 unit) - Heat Pump model number: GSCH130301 13 SER , An ARUF3030 Air Handler, And an HKR-15C Heat Pak: $5100 includes electric upgrade to 200 A,
2.) A carrier 2.5 ton 13 SEER R-22 unit($5100 includes electric upgrade to 200 A Heat Pump model Number: 25HBR 330a 2.5 TON 13seer, A FA4CNF030000 Air Handler, A KFCEH3101C15 15KW Heat Pk $5500 includes electric upgrade from 100A to 200 A,

3.) Trane 4T1UX5024A 2 Ton 15 SEER Heat Pump, A 4TEE3F31B1 Air Handler, A digital Thermostat, %8987 includes electric upgrade to from 100A 200 A,
4.) A Westinghouse 2 Ton Heat Pump, 13 SEER 1 Pad, 4 pump ups (?) 1 Digital Thermostat , and a return Plenum $4200 ( Does Not inlcude electric upgrade - we will have to provide separately

Totally confused on the right approach -- we have another contractor coming in who installs American Standard.

None of the contractors have perfomred a "Manual J" calculation which seems to be a standard request although most have been in business more than 30 years.

Can anyone help advise? Our house has ~1200 sq ft, it is a single story with 9 windows,, 3 BDR, 1 bath and was built in 1950 (with minimal insulation - which I am going change by blowing in an R38 value into the ceiling this summer.)

Thanks in advance for anyone who can shed insight into this.

this indicates that a two ton may be undersized. You need a load calculation to know for certain.

what is your electric rate? does your electric utility offer any special rate incentive for HP heating?

what is oil cost/gal?

here are my specs for a new HP system

15 SEER, 12 EER, 9 HSPF
full BTUs in both heating and cooling for rated size
R-410a refrigerant
var speed air handler
scroll compressor preferred
electronic defrost preferred
staged backup heat strips
thermostat that controls blower speed

for your area/climate, it's important that a new HP system has a good heating eff number.

as far as your quotes, I don't care for #1 or #4.
as far as Carrier, I would not go lower than the Comfort 14 Puron model.
You need to recheck mdl of the Trane quote and advise.

The cost of heating oil in this area (Cincinnati) is about $4 per gallon right now - is there a downside to keeping the oil as a backup (I've heard the smell may be an issue -- my spouse is pretty sure it should be all electric, but I'm not totally convinced yet). We do need a reliable system and we are getting older -- can't fool around -- we really need a system that will be worth owning for 25 years if we can find it...are any systems that reliable and efficient?

I spoke with our local heating/AC man - came from the Heating/Ac compnay just 2 blocks away - he seemed to be most thorough of the 3 that we've had so far, and inspected the ductwork, each vent and also the rooms. This is what he said:

" The 2.5 ton, 13 SEER carrier unit does use refirgerant R-410A unit -=> It has a 5 year parts warranty and 1 year labor, but for $25 we can get a 10 tear oarts warranty." He didn't really get the need for a matched thermostat in the system, except that he said the coil has to be right for the Heat Pump (????) and our old York was too small and wouldn't work, so he would have to lift the oil furnaceout of there to put a new coil in and either put the new electric furnace in or put the oil furace back....Does this make sense - it's giberish to me(???) (All the other have 10 year parts and 1 year labor with the exception of the westinhouse uit which has 10 year parts and labor unless the copressor or the coils go out -- then they replace the entire unit for free (pats and labor included).

It sounds liek you two either recommend a high efficiency Trane or carrier System.

I'm getting two more quotes this weekend - one guy sell American Standard and the other various brands...

do you mind stating your electric rate?

Carrier has four levels of HPs-Infinity line,Performance line,Comfort line, and the lowest Base line which you have been quoted. The base line model you have been quoted has R-22 refrig and as expected has poor efficiency numbers. If you are interested in your operating costs, then this model should be discarded.

these are the numbers you should be looking for in a new HP system

15 SEER, 12 EER, 9 HSPF
full BTUs in both heating and cooling for rated size
R-410a refrigerant
var speed air handler
scroll compressor preferred
electronic defrost preferred
staged backup heat strips
thermostat that controls blower speed

for your area/climate, it's important that a new HP system has a good heating eff number.

Because of the fossil fuel price for heating oil, I would be leaning toward getting rid of it altogether.

BTW, Am Standard is Trane's sister company as is Bryant to Carrier.

IMO

Good luck keep us posted

The Electric costs in ur area are .09 per Kilowatt hour.

The one contractor who checked out the ductwork, and seemed most thorough is also the one who quoted us the carrier (and goodman) system, and from what I'm hearing here the carrier is an R-22 system. When I spoke to him on the phone he seemed to think that it was an R410A system..so maybe hes notas good as we thought.

I will keep "tigerdudes" advice and look for a:
15 SEER, 12 EER, 9 HSPF
full BTUs in both heating and cooling for rated size (what does this mean?)
R-410a refrigerant
var speed air handler
scroll compressor preferred
electronic defrost preferred
staged backup heat strips
thermostat that controls blower speed

But so far any system I've ben quoted is over $8000 when it has a SEER of more than 14. I was trying to get a payback in 5 years (figuring to save about $1000 per year) but now I think I will just try to get the right system and contractor and hope for the best.

I'm not hearing here that any manufacturer is beter than any other -- is this true? At one point it seemed like Trane was top of the line and Carrier was right there also...but it sound slike it depends on model, which makes sense. (Any preference here on best - and most reliable - models?)

One last question - I've hear the higher end models are more sophisticated, but also havemore parts, and are likely to have worse reliability -- what are our thoughts?

Thanks again to all,

Bill

I read the website of Hallowell-Acardia -- which is the marketing literature -> This is a product (and company) I haven't heard about. The warranty period seems low compared to the others (to a novice like me, this means the system may be less reliable -- is it?). I don't understand this statement (also from their marketing department):

" efficiencies from 200%-400% throughout its operating range." (what does ths mean when compared to others?)

I will look for the forum to see the kind of conversations they are having.

Staements on the Hallowel-Acardia web site:
"Reliability: Made from time tested and industry standard components, the Acadia™ will provide you with years of service. From the durable outdoor cabinet to the simple programmable thermostat, you won’t have to worry about maintaining peak efficiency and comfort for the many heating and cooling seasons to come.

Savings: Using efficient technology has never been so cost effective. Electricity is the most price stable form of energy available today and, with the volatile fossil fuel market, homeowners are looking to electricity to provide reliable and predictable heating and cooling costs. Efficiency is the key to saving money and the Acadia™ operates at efficiencies from 200%-400% throughout its operating range."

Thanks again,

Bill

first of all, I am attaching a link for a fuel comparison calculator. the results with your electric rate and cost for oil/gal will be an eyeopener.

"One last question - I've hear the higher end models are more sophisticated, but also havemore parts, and are likely to have worse reliability -- what are our thoughts?"

I have not seen any independent study that would point to reliability problems of upper end systems as opposed to average lower end systems. Most upper end systems offer a 10 yr warranty on parts/compressor and ext warranty that includes both parts/labor is available for purchase.

Yes, high eff HP systems will cost more.

"full BTUs in both heating and cooling for rated size (what does this mean?)"

This means that you want full BTUs in both cooling and heating. For example, if you require a 2 1/2 ton system, then you want 30 KBTUs in cooling and 30 KBTUs in heating at 47 deg outside temp. Anything less and you are shortchanging yourself.

Here are a few suggestions.There are others.

Thanks again for your adviace,

post the mdl number of outside condenser and inside air handler.

td

Additional Options:
Air Cleaner: AprilAir Model 2200 = $295
Variable Speed Furnace = $485
Programmabel Digital Thermostat = $125
10 year parts and labor = $595

I would still need to get my electric upgraded for about $1700 (through a different contractor)

IMO

Is that remote for the thermostat infrared, and therefore only good in same room, or is it radio-based, so you can use it elsewhere?

What I want, is one of those new networkable thermostats, you can connect it to your home computer network, and monitor temp etc anywhere in the home with a wireless laptop, or even remotely if you have the setup for a remote login from outside....I think that would be sweeeet....

I am a bit of a gadget guy and I would be going that way, just because...although I'm sure there are lots of practical considerations, if you're leaving your house for any length of time, no doubt it can email you if there's issues, and you can fire up your heating when you're heading home, for example.
