Carrier 25VNA w/Greenspeed

12 years ago

I am planning to replace electric baseboard heat and window A/C in my 1826 Sq. Ft., one story dwelling, with the Carrier unit. Installed price is $17,900.00 before rebates. Carrier 25VNA036 Heat pump, FE4ANF0003 coil + 20 KW heat strips, Infinity air purifier, 10 supply ducts, 4 return ducts (metal, sealed and wrapped, Wiring to outdoor and attic unit, Secondary drain pan, 10 year parts and labor warranty. This is the "latest and greatest" product, so I understand that the price will be "premium", but is this a fair price for the product and the amount of work involved in the installation ?

Well, I am 5 months into the Greenspeed. The first three months electric usage was down from 8,550 KWH to 6,538 KWH, but then it got cold over the last two months, but rvrn with that, I have lowered KWK 1,698 over the five months. I did find that the Infinity thermostat is smarter than I am. I has it set for 74 degrees, but have lowered it to 71 degrees and we are comfortable. I'll know what the lower accomplished in a few days. I will never have a "normal" electric bill because I have a mother-in-law suite for my disabled daughter and have three refrigerators and two electric water heaters and a daughter that takes 20 minute HOT showers. Because of the heat pump, I no longer have the "cold spots" because the air handler is moving the air. I think that it will take a 12 month comparison before you can really make a determination as to how well the system works and since the electric increased from 6.7 to 7.4 per KWH any savings will be reduced.

Carrier Greenspeed 25VNA Heat Pump Electricity Usage in Cold Area
Q

Hi All. Live in eastern Ontario and just got installed a Greenspeed 25VNA048 heat pump w a 59MN7080 gas furnace to stop paying for oil. It was a learning curve for this system as it is an advanced heat pump system - expect the competition to ramp up their pumps HSPF to 13 also or lose the market. My coldest night so far was -15C and we got our 21C/70F indoor temp in our 2800 sq.ft house.My balance point is set for -17C/1F and I should be getting to -18C this wed/Thurs evening for a real test for the normal switch to gas furnace. Yes the system by default uses gas heat on defrost. Without it it would be blasting cold air in the ducts for 5 minutes. So the gas frnace heat modulates at 65% so to neutralize the cold air so air temp swings are minimum for comfort. Yes you can disable this on the touch screen interface in service/ setup/ heat source lockouts. Yes one can monitor electrical costs in $$$ or Kw and gas $$$ or therms on a per day/ per month and per year to date on the interface. I've experimented between the different options in choosing efficiency or comfort and there is a noticeable difference to the environment and a slight increase in costs of electricity between the two. I do prefer comfort. On an average cold day 0C/32F w -5C at night it costs me @ $5 per day in electricity and with heat on defrost w/ continuous low fan for only an additional cost of $1 every third day (.33cents per day). (yes the different areas of kw usage is separated in the readout) The only puzzle I have to resolve is last Saturday nite at 3 am the house felt cold - it was 15 F outside. Gas furnace came on for a couple of hours before pump came back ???. No codes or resetable fault codes registered on interface. The only way for the gas to go on at that temp way above the balance point is a 2 degree drop or a manual increase of temp of 2 degrees or more. So why did did happen.... stay tuned.... Gotta love saving money. Last year in October it cost me $425 in oil - this year for Oct gas+electrical $202 Included is a pic Update Jan 2014: had issues w furnace overiding heatpump prematurely and Carrier change my thermostat which had Version 9 to version 10 software - issue fixed. those who want to see what savings a heat pump can have over your specific system try this: http://sagoro.wrightsoft.com/Carrier/Default.aspx This post was edited by Cocobob on Mon, Jan 13, 14 at 23:22

Bob, I recently installed a Greenspeed but don't have enough data to reliably estimate my winter savings. According to my estimates (not the dealers) I figure I'll be saving ~$300/yr on heating costs over the next best heat pump (9 HSPF on the HP only, not the system rating) and $700+ over an 80 AFUE gas furnace. This was with a 4 ton unit. What were the results of the manual-J calc (heat gain/loss numbers)? Since the Greenspeed maintains it's BTU capacity down into colder temps it should be fairly easy to determine how many BTUs of heat the electric strips will need to produce. From that you can calculate the cost to run the heat strips annually. Alternatively, look up the AHRI number of your system and plug the "real" HSPF/SEER numbers into a calculator to compare to your existing system (or alternate systems).

I spoke with two different dealers, and they told me that when the temperature drops below -15C the heatpump make a noise since its working harder. One of them told me that he decreased the RPM and the owner asked to put back after receving his next electricity bill. They also told me that probabily that the difference between summer and winter make more relevant noise. During the summer the heat pump is too silent and someone thinks that it does not work.

Carrier heat pump 25VNA Fan spinning up only intermittently
Q
Comments (28)
Thanks for the update JB. Was the fan motor the only component you've had to replace on your system so far? I ask because I am having a similar issue with a 3-year old Carrier 24VNA0 AC unit wherein the condenser fan motor only runs for 5 seconds when the head pressure peaks. Then at some point during the cycle, the system throws the 56-OAT-OCT THERMISTOR OUT OF RANGE system event. I did the same testing that you did on your system and everything checks out good; even the thermistors. Nevertheless, I replaced the OAT-OCT thermistor assembly but this did not resolve error 56 nor did it resolve the issue with the fan motor turning on and off intermittently. This leads me to believe that the controller board cannot interpret the signals from the thermistors correctly. So, I suspect that either the controller board or the ECM fan motor needs to be replaced. I now have both parts on order and plan to replace the control board first, then if necessary the fan motor. I sure am glad Carrier gives a 10-year parts warranty because these systems apparently have issues...

I am not a Carrier dealer I am a Trane Dealer but based on what i have heard from my competitors and the premium for the greenspeed that price seems about right. The greenspeed system has me a little "green" with envy that system looks amazing I can't wait to see one running and I can't wait until my manufacturer has something to compete with it. Frigidaire also makes a fully invertor driven heat pump that has been out much longer but i think the Carrier is a better product and is a higher HSPF(heating efficiency)

A couple of ideas.

You are going to save a great deal of money on heating with a high eff heat pump system replacing baseboard electric heat.

I looked at the AhRI HP directory and I would prefer the 005 air handler to the 003 mdl quoted. I don't understand the large 20 KW heat strip. I would want about a 15 KW size and make certain it was staged. 15 KW yields about 51 KBTUs. Keep in mind , you will have about 31 KBTUs at 17 degree with the Greenspeed system.

Before I made this decision, I would get a price on a more conventional HP system like Trane and make a comparison to the Greenspeed to see if the price difference was worth it.

Dealer will remove the baseboard heating or are you leaving it in place? Is Carrier dealer including the Infinity controller as well as whole house air filter cabinet?

Infinity Control included. I will ask about the air handler. I have quotes from Carrier ( 25VNA036 - 25HNA936 - 25HPA536 ) , Trane (XL16i ) and York (YZH36 ). All quotes inclued electronic air cleaner. Trane is the lowest price, York in the middle and Carrier has the highest prices. I fear electric prices "going through the roof" if the present EPA folks have their way and I want to make sure I have the most energy efficient HVAC system.

Sounds like you have done your research.

If the system difference was $5-6 K difference, then I'm not certain the Greenspeed would be worth the difference. Only you could determine that.

The 005 Infinity air handler is a much better choice than the 003 mainly due to HSPF efficiency.

A staged 15 KW heat strip is the most you need. And it must be staged.

The system difference between 25VNA036 and 25HNA936 is $ 1,845.00.....Trane is $11,400.00....York is $ 13,300.00..
Carrier 25HNA936 is $15,055.00 and 25VNA036 is $ 16,600.00.
I read a lot of complaints about Trane, York appears to be a good unit, but dealer has one service truck, and that makes me unsure as to whether he can service the product.
My brother-in-law has had Carrier Performance HP for several years, and is very happy with the unit and service by the dealer. I just want to do this right, the first time.

Just wondering if you chose the Greenspeed? How is the system is working? Have you noticed a savings in utility bills? Hope you got the 005 air handler. I just placed an order for the Carrier Greenspeed 3 ton with the 005 air handler.

My 5 ton 25VNA was installed in late december last year. I used a Hybrid Heat gas furnace, the 97% efficient one for back-up. I had my balance point set to 33F. House is multiple zones, 4500ft2. Area is pacific NW.

Gas usage went from an avg of 7 therms/day to 1.7 therms/day. Most of the baseline gas usage (1.2 therms) is that used for water heating.

kwh usage was actually flat. But that was due to electricity efficiency changes that were made the same time: timers on water feature pumps (shutting them down at night), photo-sensors controlling landscaping lights, switch to LED lighting throughout home (inside and out), among other changes. After winter passed into summer, I saw kwh/day drop from 98 to 79. So I think that difference represents the incremental increase in electricity usage due to HP operation: 19 kwh/heating day.

At my rates for electricity, the HP cost per winter month was $62. At my natural gas rate per therm, the gas cost reduction per month was $166. So that's a net reduction of $100/month for heating expense per heating month. And we have about 6 of those per year.

One note about the numbers: our gas rates were basically at record lows. They were 30 to 40% less than that typical of previous years.

Hi, i'm debating purchasing a greenspeed in the next couple weeks, i'm very very curious about your winter bills, can you please post for us?
Thanks!

Pulled the trigger, summer electric bills this summer were about 400 kw total for my house. My daily carrier greenspeed usage was about $.40 per day.
Super cheap!
I'm now waiting for winter, anyone can share their winter bills / usage with me?

Thanks!!
