Suggest you use the search function at the bottom of the home page. There have been some recent threads on the GreenSpeed system. It is obviously being marketed as a less expensive alternative to GEO HP.

Hey Rayball,

Also live in MA and recently installed the Greenspeed heat pump in April. Thing works very well and efficient for my experience so far, though mostly cooling. However, I did research and there was another gentleman on the boards from MA who was able to give me all of his costs for this past winter which we know was brutal and they were VERY reasonable, electric costs of the heat pump for the winter were as follows:
December $204
January: $258
February: $226
House was 2300 sq feet, well insulated per the person.

His username was Sabs83 - really nice guy and very informative and helpful to me in my search.

Best part the Summer numbers which I can confirm so far between $20-$45 cooling.

Obviously much better than oil to heat and get a very efficient AC.

Thank you siry2j, I appreciate the response. I did try reaching out to Sabs83 because of the Massachusetts connection but have not heard back. I assume this electrical cost is for the heat pump portion of his electric bill not his entire bill. Hopefully this post will help me get some other responses, its really helpful to hear back. Did you find that your dealer was well prepared to install this unit?

Yeah the bill was just for the quoted cost from the WIFI thermostat from the Carrier Infinity line of the heat pump itself.

It's hard to get a sense from the dealer of what your confidence should be since often times they just send out a sales person, I made sure I talked to someone from the company who could give me answers and if they could not then I went elsewhere. Believe me in MA everything comes with a premium price tag and you have to look around. Not sure what area you are in, but if you want to send me a private message I can see if we were close.
The forum has been great here for me in specifying what exact details you need to look for and get to have the most efficient product such as air handler model numbers (F005 or 006), serial numbers to ensure you get the new carrier aluminum fan/coil (Suffix of the model number is an L) but this does not mean the dealer/HVAC will install it correctly. I'd make sure to use a carrier certified dealer at the minimum and make sure the dealer is able to explain everything to you including giving you rationale. Search around here as Tigerdunes has a valuable piece of standard advice that is posted.

Siry2j, emailing you is not enabled? Rayball and Sabs83 I sent email to you.

We are also in MA and am looking into putting Bryant 280A heat pump which is same as Carrier Greenspeed 25VNA could you please let me know if you find out cost information.

I did some research which I mentioned in the following post http://ths.gardenweb.com/forums/load/hvac/msg06150038548.html.

Thank you.

sgw-ma.. This is the quote I received from a highly qualified Carrier Dealer so far. Understand I already own Carrier Infinity Air Handlers and I would be swapping out my Performance Series Condensers which were only being used for AC. I have a 3800 sq ft home with 5 zones and I have to say the Carrier system has been great. My oil boiler is 60 plus years old but I have been mostly heating with a Seton Wood Boiler since 2006 and thus my oil needs have been minimized. I hope this information is helpful and invite anyone who has some Carrier Greenspeed 25VNA experience to tell me what you think of the quoted information which is below:
Installation of two 3 ton Carrier Greenspeed condensers for heating operation.
Installation to include:
- 2 Carrier Greenspeed 3 ton condensers
- Removal of existing condenser (owner keeping)
- Elevated condenser pads
- Electrical and control wiring
- Relays as needed
- Repipe system and charge system
Total Price......................................13,575.00

I will likely ask them to quote me on heating strips as I see myself long term wise doing less and less with the wood boiler (a lot of work). My hope is that I can find someone to buy my Performance Series 3 Ton Condensers which are lightly used. Hope this info is helpful and I will also post this on your other thread. By the way I live in Attleboro, MA which is on the RI border.

Rayball, wrt your original question, I spoke to two references and Siry2j (sent email directly) and they all seem to be happy with the heat pump choice so far.

As for oil/wood/heat strips decision, that becomes a little bit complicated based on your local rates for oil, wood, electric, natural gas, etc. Do you have natural gas? It theoretically best after a high HSPF heat pump. You use this calculator that other people pointed out www.eia.gov/neic/experts/heatcalc.xls to do you calculations. Just enter your rates appropriately.

Going to heat strip will need a bigger amp circuit wiring (depending on the kw installed) to be done. Do you have 200Amp main panel? Some older houses only had 100Amps. You have big sqft so you might have more appliances, etc. You may also have to check that you have sufficient remaining amps for the new circuit. Otherwise you will need to install more stuff. If you do you might want to install staged. Just my knowledge, not an expert.

For Rayball

I assume dealer has looked at your Infinity air handlers. You want the FE4 005 or 006 size to maximize the HSPF heating efficiency for a 3 ton Greenspeed.

See below.

And while I wish you well with your endeavor to sell your Performance condensers, that is usually an uphill hurdle. I would ask dealer if he would offer anything. Used HVAC is difficult to sell.

IMO

If youâÂÂre living in a very cold winter climate you may want to up size the 25VNAs by 1-ton each, otherwise there may be issues with noise. ThatâÂÂs what is being done in the Montreal Quebec region.

You may also want 2 - Carrier Infinity SYSTXCCITN01 T-stats or the WiFi version, SYSTXCCITW01.

This thread is helpful. I live in Dighton and am looking at a dual system 2 ton Lennox 25XP or carrier 25vna. On the Lennox, they told me it didn't need a heat strip. I especially appreciate seeing the MA winter numbers.

Re: chjch

Unless the furnace you will be installing is gas I would say that you DO need backup electric heat strips. What happens if the compressor goes into lockout? You have no heat, not to mention the defrost mode.

We have a geothermal HP that doesnâÂÂt even have a defrost mode and still have heat strips. I would be reluctant doing business with someone giving me that information.

Hi Tigerdunes and others with great knowledge

As a continuation to my post, my original air handler I have a FE4ANF003...ITS NOT AN 004 OR 005. How much of a difference does that make in your opinion. I have 2 of these air handlers, and want install Carrier 25VNA Greenspeed to heat and cool my Massachusetts Home

For Rayball

Obviously, you were not paying attention to my posts and recommendation. The main purpose of the Greenspeed is the low temp feature and the HSPF heating efficiency. That's what you are paying for. While the 003 air handler is an AHRI Directory match, it is not the best match as far as HSPF. There is a significant difference from a 10.5 HSPF to a 12-13 HSPF.

See below for comparison. I posted same on July 4th..

You will need to decide whether it is worth changing the air handlers out from the 003 to 005-006. Probably not but plan on higher operating costs in the winter. The 2 areas that take a hit are the cooling BTUs and the HSPF heating efficiency. Dealer should be able to give you some est operating cost differences.

IMO
