Been working for a small HVAC company for thirty years that are Carrier dealer.these systems are extremely expensive for the customer.the parts are astronomically expensive when they go out and the warranty has expired.when you tell the customer the circuit board outside is bad and you have to order it and it’s 1200 dollars,they go crazy.i personally don’t believe you save enough in energy cost to justify spending on these systems.
Yep I feel ya I really don’t like them that much myself and personally I prefer the 24acb7 and 58tp0 furnace matchup. The reliability of the two speed system is unmatched imo
Great content! I'm a bryant TM in the northern CA market and my Dealers are getting great customer feedback so far. Excited to see these units in 6months-1year and some service work performed via Bluetooth. Should really help more "green" technicians and assist with the labor force shortage.
It takes 7 hours to do a change out on this Computer with a compressor, 2 fan motors, you will save $70.00 each year on electric bill. Will take the boss or a $40.00 a hour tech to start this up and about 6 hours to read the books for the correct setup pins. In 1993 carrier gave life time warranty 0n heat exchanger all are rusted out. Indoor blower will last till the first lighten storm. The motor will cost $1600.00 to change out in 6 0r 7 years. We will only give 5 years on that GreenSpeed. Give you a 10 year on a 14 to 16 seer. unit that last 20 years. Carrier trophy units nothing but call backs. and they will blame it on the person that installed it. boards short out from ants, homeowner must keep it under contract maintenance if not we won't fix. 40 year tech stay in the 14 to 16 seer units it will run a long time
Installed one of these a week ago and couldn’t figure out why the stat wouldn’t find the outdoor unit. Definitely have to update the stat then reinstall equipment on the stat
I just installed a new Goodman 16 SEER HVAC system myself. The Goodman furnace supports Bluetooth and I was to upgrade the firmware and configure the HVAC using the free Goodman CoolCloudHAC app. I had never used the app before but it was intuitive and easy for me. I agree that flashing firmware is much faster using an SD-Card. Just make sure you have the latest stable version on the card before flashing.
I replaced the inverter board under warranty for a Green speed from 2012. Took a week to get approved by Carrier probably because it was $3,800!! Out of warranty repairs for these type of units are insane.
Airflow is ALWAYS the first thing to verify, just like water flow is the first thing to verify when starting up, or troubleshooting a chiller. On that number 10 wire... the wire size also depends , on the length, so it is not cut and dry. Carrier supplies specific guidelines for sizing the wire, and it is not minimum circuit ampacity. There have been a lot of hard or no starts due to low voltage at LRA, due to electricians trying to get by with the minimum wire size on single phase residential units without hard start kits. I know this unit is probably different because it is inverter driven and probably has a soft start, that would reduce the surge.
Thankful that after 45 years in the hvac trade I retired 4 years ago. While technology has drastically changed over the years I cannot justify the overall cost and complexity of these systems. I was a Carrier service tech for most of my career and I would never recommend one of these units. The return on investment will never be accomplished and after the warranty is over any repairs will be astronomical. Engineers coming out of school like to impress and design systems that, on paper, seem great but, they are not REAL WORLD applicable.
Unfortunately it is our government that is forcing these changes with the higher efficiency standards....just like our autos. Have you purchased your EV car yet....I hope not. I have not either. 😊 We both can enjoy retirement. It use to be that the 3 biggest issues were leaks, leaks and leaks (air, refrigerant and water). Those still exist, but the biggest problems have been for some time now are software revisions.
At 08:02, we see the number plate: the condenser unit is a Carrier 25VNA448A300: AHRI tested 22 SEER / 13.5 EER / 11 HSPF (per Carrier product data sheet 25VNA4-01PD dated 02/20)
Thanks for making this, glad to get a look at the system! May put one of these in my house (unless I cheap out and do a VNA8...) That ICM493 is important, we lost our first two compressors due to dirty power.
Could you pair the ICM493 with a fused rotary disconnect? The rotary disconnect and breaker will require some selective coordination though I would always want the fused disconnect to trip first. Also what are you thoughts on a GFCI breaker any issues with the infinity systems. Lots of problems with other systems I have heard about in other states. However it is a NEC2020 code requirement.
Lighting can splinter to liquid line and if low voltage wires are touching LL,, it will jump to low voltage wire and take out the board fuses and communication drivers. Lighting and/or static electricity can blow a hole in the CPU and take out some code. I've had this happen a half dozen times that I've personally experienced. I wish you would have mentioned that the heating check chart is NOT a charging chart. It's A WAG method and only there as a tool for troubleshooting refrigerant issues in heating mode....not changing. Excellent video.
I'm not an A/C tech but I really enjoyed this video. Great tips for techs and the new Carrier Infinity with Greenspeed Extreme Intelligence is super cool! ;)
At 04:50, you can see that the clearance from the condenser unit to the building is less than 12" (est.). Also, at )1:30, to the left of the condenser unit, there is vegetation encroaching right up to the side of the condenser unit. These will reduce the effectiveness of the condenser unit unacceptably. I am aware that the factory specifications give the clearance to the building as six inches (6"), but the unit is some 44" tall and requires much more clearance to allow air to flow with acceptable friction loss. Factory specifications notwithstanding, you cannot fool physics. My proposal would be to angle the unit 45 degrees, so that the service panel is the part closest to the building and to maintain minimum 24" separation from the building. Also, get rid of that vegetation to a distance of 44" minimum. Thanks for showing us your work; very generous and courageous, guys.
You obviously have too much time on your hands. Why would you put the control panel against the building? Also the vegetation around the unit will not affect the air flow. If you tried all the stuff that you’re proposing that Customer would laugh in your face at the cost.
Anything in path of air discharge that results in the discharge air to be re-circulated, reduces the capacity of the unit. So does a dirty/blocked coil. Fan is also variable like compressor.
Your knowledge of these was awesome to watch. I have a 4 yr old infinity greenspeed that is giving us static pressure, sweating, and failed compressor issues. It runs good static up til 1200 cfm then goes way high. 4 ton system. Any idea what to look into first? Ducts or adjust blower speed?
I have this unit and I wouldn’t recommend it to anybody that lives in cold areas. Unit is great in summertime but in cold weather I live in ct it’s terrible. Today it is 10 degrees outside and the outdoor unit is not even turning on!!! Only air handler with aux heat. 1 year into it had a part go bad cost me $700 to fix because carrier didn’t want to cover their own warranty. This unit was the biggest mistake I ever made
"The customer is thrilled with the system..." I predict that will change within two years after they have have spent thousands of dollars in repairs for all of that fancy "connected" tech. Replace this board here and that thermostat there, it tends to add up very quickly and causes ill will towards the company that sold it to them and then charged them to come out and replace the broken bits all within the "warranty" period. I see this happen around here with Trane and Carrier "smart" systems, I can just imagine what all of that connected equipment is going to cost to replace.
You always want to look at filter manufactured spec sheet to compare pressure drop at given CFM/FPM of free area of filter and then install filter so to use all of the free area of the filter.
Why would a customer pay extra for all that bluetooth junk just to make the service tech's life easier? A savings not passed on to the customer. As a home owner, the first thing you should ask is how much does it costs to fix. I'll deal with the extra $10 a month in electricity.
Hi I just got a Carrier Infinity system not green speed, 18 Seer, got some errors excessive static press 14 times , and Humidity sensor error 1 time , noise level is expected to be about 300 and is testing at 1400 , can it be the Return , or duct causing this press error
HVAC School That makes perfect sense. Here in Pennsylvania we have to put pump ups under the heat pumps. Keep up your great videos and webinars. Thanks Bryan.
Bryan- at 8:03 I assume this has two drain pans, one vertical, one horizontal, allowing you to remove the horizontal on vertical installs? Also regarding your surge protection device between shutoff and condenser, how do you determine where to set the limits on that device given range carrier allows for this unit to be 197-253 volts ?
Hi Excuse me my English not good Q.1 Why split ( cooled only ) ac compressor have thermal isolation wrapped around in hot county ( T3 ) -not on the top of compressor only around ? max weather temperature ~ 49°C/120°F Q.2 Is this make it jump from T1 to T3 ?
Are these systems more than 5 stages? I noticed in the carrier control no stage is shown by the compressor rpm. Do you know what type of compressor is in this unit? Rotary or scroll? Just curious.
The inflation is killing consumers. I had to get a system, as mine was toast and not doing the job. I opened a couple 15 month, 0 APR credit cards and put the remainder on a Carrier credit card through wells fargo with 12 month 0 APR. Its basically free money. The monthly payment is like an extra grocery run per month. My family budget was not effected too much. I had to add some supply and return lines and upgraded to a 2-zone system. It makes it incredibly comfortable now. No more cold feeling just to try and avoid a high electric bill. Also, the zone allows me to leave it on when one zone gets to temperature but not the master bedroom. Previously the system would over heat one zone while it continued to get the zone with the thermostat warmer. Also, I love that it dehumidifies on its own without cooling the house down too much.
FLY EAGLES FLY Bleed Green I was just wondering if they changed testing standards bc they used to be at a fixed compressor speed even if it was vrf. I’ve got a couple Mitsubishi hyper heats installed in my home and there only listed for 18 deer ductless. And of course seer rating is also impacted by unit capacity.
I've been in the industry for 30 years. I all for innovation. But how do you tell a customer that when the system is out of warranty and a circuit board goes bad when its 95 out and its three weeks out from the factory. Sometimes say for contactor and capacitor and general defrost board if its a heat pump. I wouldn't put that in my house. All the money you saved is right out the door on the first repair.
@@sprockkets sorry your compressor failed, its covered under warranty, however labor costs arent covered, or the contractor who installed this system didnt register it, so 6 years later, the cost to change this compressor is almost a third of a new condenser but only for a year. Dont worry... the money you saved on electricity covers it
At 05:50, we see some details involving Bluetooth connectivity. Buyers should be aware that Bluetooth technology is not at all secure; Bluetooth capability renders your equipment open to exploitation. See "Bluetooth Security Issue" in Forbes, 2019 Aug 15, or blog dot arc dot com / 2019 / 04.
Looks like they got rid of that muffler on the suction line also, nice
Yes!
I was literally just going to ask about that glad I looked first hated those mufflers
@@mrtryhard1996 The muffler was for high heat rpms. The new unit has a quiet mode that allows you to limit the capacity in that condition if necessary
@@randyponson5890 The old one has that feature too, you can limit the RPMs. Somewhere deep in the settings.
Per the Installation instructions (Carrier 25VNA-5SI dated 04/14, page 2), "Always install the factory-supplied muffler (part #LM10KK003) on the vapor line as described in the Factory Supplied Muffler Installation section of these instructions".

People drive fancy cars that have the same issue. Whenever you buy the best of anything, repairs are not cheap.
Yep I feel ya I really don’t like them that much myself and personally I prefer the 24acb7 and 58tp0 furnace matchup. The reliability of the two speed system is unmatched imo
You don't buy these unit to save money you buy them to have the most comfortable house possible

Mine is 5 years old and has never had a repair. Sometimes it actually is the installer
How’s that saying go ? keep it simple stupid . I can see the inverters costing an arm and a leg . .

Nice install. Have one question for you. Do you not install your heat pumps on pump up feet?
No they only do that for snow if you’re in a flood zone then we have to put it up higher
No, in fact in florida we cannot use feet due to Hurricane code

Lennox has the 25 seer we install. Does carrier only sell a 22?
I don’t know how they would have got 22seer with a 4ton ducted unit with a txv indoor metering device.
My thoughts is that they used larger coils. just a guess though
Throttling up the compressors and the motors. Bypassing refrigerant and reusing it
Same TXV as the 14 seer
Randall.. the DC drive ramping up and down the compressor. In the "Right" conditions it will produce 22 SEER. But an anominal SEER its probably 16-18.
FLY EAGLES FLY Bleed Green I was just wondering if they changed testing standards bc they used to be at a fixed compressor speed even if it was vrf.

Has anyone had issues with the PEV on these
Do you break your vacuum with the micron gauge attached? For some reason no one except HVACSERVICETECH shows the vacuum being broken.
Yes we do. The bluvac micron Gauge has no issue with it.
Also Craig is the man
I got a valve core removal tool just for my micron gauge. Seal it off before releasing refrigerant.
