The exhaust fans air hits the wall where is the exhaust air going does it effect the efficiency cuz air is not distributed correctly
This unit is 5 inches off the house wall with several feet to the left and right, as well as 44 inches in front of the fans. This we exceed the recommend manufacturer clearances required. The manufacturer clearance specifications can be found in the installation manual on Page 8, figure 8. Here they are for your reference - 4 inches from the wall, 24 inches left, 24 inches right and 24 inches in front.
Great video. I am in the same boat. Although I had a duel fuel system installed. 38MURAQ48AA3 paired with the 57TP1. The installer originally thought they would need to run the 2 wire but once they started the install they told me they wouldn't need to and they could use the existing wiring from the old system. They also installed an ecobee. How would this effect my system operationally not having the 2 wire? Does this mean I am not getting variable speed without the carrier thermostat? Is it worthwhile to have it installed now? Thanks for the awesome info. Btw, I am in San Diego. Do you service this area?
Yes, when paired with the Ecobee thermostat the system is not a true variable speed system. The outside condenser will go up and down in speeds but the inside blower motor will not. To have the true variable speed capabilities you would need to pair your system with the Carrier communicating thermostat. Unfortunately the Carrier thermostat is not very nice looking, does not have wifi or some of the other features of the Ecobee. So other than being able to have the variable speed communicating capabilities with the system it is not very good. For those reasons I have not installed that thermostat with this system. My customers are buying the 38MURA unit for the lower sound rating and compact design.
@albertairinc.1140 does it work with nest thermostat? For variable speed?
@@sergiodoordie319 No. You would have to use the Carrier communicating thermostat. Any other thermostat will make that system a single stage.
Ok, so I have a deck that cantalevers off the house, and the traditional unit is out in the heat of the day and the fan exhaust is vertical. The fins, although fenced are exposed to the hazards of hail and debris (lawnmowing). So, the unit can be set under a deck and exhausted horizontally, yes? And the fins (don't see them in your video, are on the backside, facing the structure, yes? Minimum setback from vertical and horizontal surfaces?
Yes, the units fans blow out horizontally. Yes, the coil (fins) are on the back of the unit and right side of the unit. Set back is as follows - 4 inches off a wall, 24 inches in front, 24 inches on right, 4 inches on left and 24 inches on top.
I'm confused on the heat pump vs a/c distinction when it comes to the federal tax credit and the SEER2 >= 16 requirement.
Is this unit not labeled/marketed as a heat pump meaning it would always fall under the heat pump criteria for the rebate?
When paired with a gas furnace, is the reverse heat pump ability disabled or something, invalidating the tax credit?
What if it it was paired with a 40MUAA Fan Coil, is it a "heat pump" then?
For contrast, I'm aware that Carrier has specific, dedicated Central A/C units, like the 24SPA6 Performance 16 that could never function as a heat pump.
This Carrier 38MURAQ can be wired as a heat pump condenser with the Carrier 40MUAA fan coil or Carrier FV4 fan coil and would qualify for the split ducted heat pump Federal Tax credit up to $2,000 if the system meets the 15.2+SEER2/11.7+EER2/7.8 HSPF requirement (note: not all sizes will qualify). An AHRI certificate for the system match up is needed.
The Carrier 38MURAQ can also be wired as an AC only condenser and matched with a Carrier gas furnace and evaporator coil. This would qualify for the split AC Federal Tax credit up to $600 if the system meets the 16+SEER2/12+EER2 requirement. (note: not all sizes will qualify). An AHRI certificate for the system match up is needed.
That is correct. The Carrier central AC condensers can only be AC condensers. By contrast, any Carrier heat pump condenser can be a heat pump when matched with a fan coil or can be wired for AC only and be an AC condenser.
I hope this answers you questions. It can be very confusing. And to make it more confusing there are different efficiency criteria for the tax credits based on your location in the country. All of the efficiencies listed above are for the south region tax credit criteria. They will differ if you are located in the north.
@@fijiman88 Thanks for the info, very helpful. 👍
I'm in Irvine do I qualify foe rebate?
Depending on the match up this will qualify for rebates from Carrier, Comfortably CA and Clean tech CA.
How do people like the side discharge when installed facing backyard with regards to hot air??
Typically these units are placed on the side yard where you would just be walking by the condenser and feel a little air blowing on you. But if you were sitting in front of it for a long period of time you would get hot and uncomfortable.
Wonderful video, Nick. Very informative.
Thank you for the feedback
Does variable speed feature work with non-communicating thermostat like Ecobee? I am under impression it would become a single/two stage system if pairing with nest or Ecobee.
No, you have to match it with the Carrier communicating thermostat
Day & Night had one equipped with a third party stat option and I’ll be install two of them next month.
@@albertairinc.1140 Hello, after a very, very long saga with our AC company we are getting the 38 and 40 installed. It is more important to us to have the variable speed than the convenience of the ecobee. Is the Carrier thermostat you are referring to the Infinity thermostat (~$800) or something else? Thanks in advance. Wish you guys were in our area so we could have had you handle the installation. I'm really shocked most people aren't interested in the variable speed system...that is the whole reason we asked for this setup from our HVAC company.
@@exilio2690 The thermostat that goes with that system to make it fully communicating and variable speed indoors and out is model # KSACN1001AAA. The Carrier Infinity thermostat you referenced will not work with that system.
@@albertairinc.1140 Thank you for the quick reply! That is very helpful to know. In you professional opinion, do people truly feel/see the difference between using an ecobee/2 stage function versus using the carrier thermostat and true variable speed? It has been such an ordeal with our HVAC people I don't want to drive them crazy with another detail they have forgotten (they have installed the wrong system twice now). Thanks again, Nick. I know this doesn't directly make you money so I appreciate your free advice and insights.
Good looking install.
Thank you
This units are pretty nice and quite but on efficient are pretty poor EER are very low 😢
Thank you for the comment. People do not typically buy these for the efficiency rating. They buy them for the compact design and low sound rating. Although in some sizes they get a good SEER rating and an ok EER rating.
Very few reviews on this unit. I assume this is the same size for a 3.5 unit? There are deals on this unit right now. But I haven't a clue how dependable they are compared to Daiken and AC pro units. These look VERY similar to AC pro units. Which would mean the 5 ton unit is very similar to the 3.5 ton unit? Nice info!!
Carrier does not make this unit in 3.5 ton. It comes in 3 ton, 4 ton and 5 ton. The 4 ton and 5 ton are the same size as the condenser in the video. Right now there is a Carrier Rebate and other rebates depending on configuration and size you install. These condensers are based on the Carrier ductless split condensers that have been out for many years. So they are very reliable and we have had no issues with them so far. They are similar to the AC Pro slimline condenser in the way they are designed and work. Thank you for your comments.
@@albertairinc.1140 Your information is very helpful. I think you're in Anaheim. I'm going to try and make a call and get more info. Thanks again. Anyone I should ask for? What's the appropriate air handler for a 4 ton? which all I need is a 3 or 3.5 ton. 1500 sq ft.
@@twoweeledsoto6072 You can ask for me, Nick Albert. I can help you with any questions.
What’s exact the model number？thanks
38MURAQ60AA3
24 volt wiring?
Yes, it has 24 volt wiring.
How reliable are these slimline units vs the old style like the one next to it?
They are very reliable. They are based on the Carrier ductless split condensers that have been out for many years.
@@albertairinc.1140 thank you for replying.
@@albertairinc.1140is this better than an infinity 5 ton? What advantages or disadvantages does it have?
Nice unit! I got the 2-ton version installed and it is quiet and efficient. Mine is paired with the 40MUAA fan coil. The hvac company that hooked it up used "wiring scenario 3" so there are 24v wiring from the ecobee thermostat to both indoor and outdoor units. After looking at the manual, it seems like they should have used "wiring scenario 1" which uses a 2-wire communicating connection between indoor and outdoor units, and 24v wiring between the ecobee and indoor unit. What do you think?
We usually use the Ecobee thermostat with this system as well with the same wiring hook up you have. If you do the 2 wire scenario you would have to use the Carrier thermostat for that to work. With the Carrier thermostat you would get a true variable speed communicating system with the 38MURAQ and 40MUAA.
@@albertairinc.1140 Thanks for the reply! With the 40MUAA there is another option in the Connection Diagrams section of the manual. It's "Scenario 1", where the indoor and outdoor units are connected with a 2-wire communicating link and the ecobee is wired with 24v to the indoor unit only. Would you be so kind to check it out and let me know what you think?
@@albertairinc.1140 Check out 'scenario 1' in the 40muaa manual. It shows 2-wire communication between indoor/outdoor unit but 24v connection to the thermostat.
How much did it cost you?
@@corymacdonald383 About $8000 (Canadian) out of pocket, after taxes and rebates. That's for both the indoor and outoor units, installed, with a new humidifier and filter platform.
Very nice and quiet. My neighbor installed a 5 ton just like it and it's 76 dB at high speed and the noise just passes right thru a block wall, vinyl fence and my house wall so that I hear all the low frequency noise 63 hz and 125 hz and my thought is that's compressor noise and maybe something wrong with this unit or the install! Dealer says it's my problem not his too.
I'm sorry to heat that. The units I have installed have been true to the manufacturers sound rating specs. Compressors can make more or less noise based on many factors. Here are a few factors that we check when installing these units. 1 - Refrigerant lines are correct size and install a by-flow 163s filter dryer. 2 - The condenser is set to the manufacturer specs for clearances from walls and other obstructions. 3 - The return and supply air is correct for the size of the system being installed. 4 - The unit comes critically charged for 25 feet of refrigerant lines. For every 1 foot after that the unit needs .6 ounces of refrigerant to be weighed in. 5 - The unit is wired correctly for the type of FAU and thermostat being used. I hope this helps.
@@albertairinc.1140 Thanks so much for the reply. It's about 7" from the house wall and 30" from the slump stone wall. About 4 feet below my house and lots on hard reflecting surfaces. But I used my dBA meter 30" from it and low speed was 69-70 and high 76 dB so something is wrong. Ecobee so they only get low and high speeds and the high speed runs for 45 sec or more after every cycle. The Dealer here says it's not his problem and building walls doesn't help for the 63 and 125 hz peaks driving these levels.
OH I wanted to add, it's 5 tons for a 1987 2475 sq ft house with new vinyl windows and good insulation. Oversized and that's typical of dealers here ignoring Manual J calc and using the "rule of thumb"
Thanks again, good job!
@@sdcoffeeroaster You're welcome. From you description it could be oversized and that can cause the noise to be higher than it should.
@@albertairinc.1140 My 5 stage infinity is oversized by these guys too and they would NOT install a 3 ton for my 2076 sq ft house. But since it's 5 stage, it's only hit the 3rd stage of 5 once on a 110 deg day, very rare in San Diego..supporting my manual J calcs. And it's only 49 dB from the side and also exhaust straight up.
@@albertairinc.1140I don't want to hog your post because I'm sure installed correctly like you do these unts are amazing. I just did a quick couple of videos and posted the high speed run pretty far and above this 5 ton and thru a top rail of the vinyl fence and recorded 66-67 dBA. It's 76 dBA down next to the unit and I did hear 3 very differnt speeds that are in other videos I didn't post or 51 dBA, 58 dBA and then 67 dBA, with a 41 dBA ambient reading . ua-cam.com/users/shorts8nhWb-SCAvM
Hi Nick! We just got a Carrier 4 ton 38MURA installed to replace a 4 ton Bryant Preferred slim line that had amp draw issues. The MURA runs much, much quieter especially on start up and when it shuts off! However at the end of every single cooling cycle it stops then it immediately runs again for 1 minute with the fan running in the opposite direction and the fan runs at a much higher speed (most likely max speed) than when it is cooling creating a lot more noise which is very annoying at night. My installer called someone at Carrier and they said this is a locked in setting to clear out any debris from the back of the unit after every cycle and cant be adjusted. Do you have any insight on this? Is there any way to reduce the fan speed on that 1 minute cycle that runs after every cycle or even disable it completely? This is the only annoying thing about this model, it sounds like a jet engine taking off immediately after every cycle. Thank you!! And great videos!
I would need to know a little more about the system. What indoor unit did you match the 38MURA with? What size is the system? What thermostat are you using with the system? And what is the wiring configuration?
Hi Nick, it’s a 4 ton system paired with a Bryant Legacy 60,000 BTU furnace and an ecobee thermostat. not sure what wiring they used. We actually live in Orange County would it be easier to call and have u take a look?
@@ryryryryry55757 I am going to talk with my Carrier rep about this issue and see what he says. If you would like us to come out and do a diagnostic we can. It is $109 for the diagnostic fee.
@@albertairinc.1140 Awesome, thanks so much Nick! We'll see what he says, and I'll give you a call to come out if he says there's a solution.
@@ryryryryry55757 So I do know about this function on the condenser. I asked my Carrier rep to confirm this and see if there is anything we can do about it based on system wiring, thermostat, settings, programming, etc.. I just got a reply to my email I sent him. He said this "Yes it is doing what it is designed to do; runs for 30 sec opposite direction to blow the coil clean will do this after cycle ;can not do anything about it, factory programmed TO KEEP THE COIL CLEAN." So, unfortunately there is nothing we can do to stop the this cycle on the condenser from happening. I am sorry for your inconvenience with the noise issue.
