This unit was put in approximately 4 years ago, we have been back every year for cleanings and have not run into this being an issue.

Thank you for the input. I was looking for your install videos to see how you do it but I couldn’t find any…

LMAO I was thinking the same thing I never seen it being soldered

He crimped it with the battery powered crimp tool.

Hi Alex, although it’s a circuit air gets trapped at the top of radiator or you could have what’s called mono flow tees in your system which are working improperly. I would have a service tech come over and take a look.

Mine is also 15 years old. They don't have to be routinely replaced.

Thank you! It was one of our first videos so we learned a lot from it. Unfortunately I can’t change it now but our new ones we make I try to be more precise.

Do you want to use it for heat? Feel free to call me. 518-650-2000

We have a Daikin 2 ton mini-split heat pump. We live on the water in SC and our foundation is elevated so our house floor is always cold in the winter. The Daikin unit made our place so comfortable in winter and summer. The heat pump is awesome, works down to below freezing, the few days of the year that happens. When we moved here we had a Trane heat pump which was a horrible heater, blew out cold ducted air for hours. It was so bad I stopped using it and bought electric resistance floor heaters. I would urge you not to oversize though, it causes excess humidity because the unit is up to temp too quickly. We have HVAC problems with contractors here, they all want to charge double to put in a system. I am learning to install and service them myself…

@@ericafors6039 Feel free to reach out if you have any questions/concerns. 518-650-2000

Check your blower wheel. Turn it off and manually open up the front louver. Shine a flashlight inside the unit and check the blower wheel. If it has anything on the blades of the blower wheel then it has to be cleaned. It's at this point where the differences become clear. Try removing that blower wheel to clean it. Good luck.

Can you reference the portion of the install manual that states that?

@@kevinrafferty9748 of course , these cards (former Marine and Martin) did not follow through and back up their claims

Thank you for the input. The customer wanted that location due to snow fall issues coming from the way his roof is. He actually had an engineer tell us that was the safest location. We put in a lot of units and I understand the concern but in this situation my hands were tied. The customer had sent the photos to the manufacturer and the town for inspection so the location was pre-determined.

@@kevinrafferty9748 I am talking about the head pressure of condensing unit from the upper cassette!

@@MissionaryForMexico I'm not really sure what you're talking about. If you pull up the manual or talk to the company they will tell you how far away each unit can be including height. This video has been seen by some of the engineers and none of them have said there's anything wrong with location. If you send me some of your installs maybe I'll see what you've done to fix this issue you think we have.

@@kevinrafferty9748 You will more then likely learn after some time, of the installation, the strain on the condensing unit being from the location of upper cassette! I could be wrong, but what seen occur on a condensing unit when the cassette was four floors up, it even required chilling refergrint bottle just to be able to service proper amount!

@@MissionaryForMexico We install roughly 50 mini splits per season and have never had the issue your talking about. If you can please have a service tech from the manufacturer you've spoken to who has told you about this issue I will gladly take the call.

I'm from AZ and have a 5 zone Mitsubishi mini split on order. Been back ordered for two months. Wondering if Daikan was any better although I understand they are both top of the line.

You made a ride decision going with Mitsubishi. A lot of companies install ductless systems but you rarely hear them discuss servicing them. Every brand ductless system will require that the indoor system be cleaned and Daikin is by far the worst to service.

@@Rewind_Start_Over Perhaps the reason the Trane/American Standard joined forces with Mitsubishi to manufacture/sell mini split units. 🤑🤑

To be honest I really don't get hung up on who made what or where it comes from. I prefer Mitsubishi simple because out of all the manufactures Mitsubishi sucks the least. I've worked on Fujitsu, Daikin, LG, Mitsubishi, Sanyo, Mr.Cool, Carrier, Lennox and the only manufacturer that has actually taken the time to design their product to be taken apart and cleaned properly is Mitsubishi. Ductless indoor units have a common problem across the board. The blower wheels get funky. I've seen mold, dirt and whatnot and the only way to clean them is to remove the blower wheel, drain pan, and all the plastics. When I'm done it looks brand new. For anybody that has a ductless system regardless of the manufacturer and wants their system to perform better simple turn it off manually open up the front vane/louver and shine a flash light into the unit. You are looking for the big blower wheel in the rear. It spans the entire width of the indoor unit. Have a look at the blades of the blower wheel. Is it filthy? Maybe it's splitting black chucks out of it or it stopped moving air like it did when it was new. It needs to be cleaned.

Daikin is pioneer in airconditioning.

Or shut offs before and after circulator pumps and auto vents.

@@philipajarapoo7675 Why didn't you put a shutoff valve between the expansion tank and the system?

Thank you. They were new to all of this and wanted to use another brand that we've seen many issues with over the past few years. I know where you're coming from and I think I just misworded it. I tell all of my customers I am anything but a salesman, in the end it's their inevitable decision and something I want them to be happy with for years to come.

@@kevinrafferty9748 Don’t sweat this stupid comment. Betty Smith is a Karen.

@@axelgiovanni1031 Mega-Karen

Absolutely. You'll see quite a bit of applications where this is acceptable. The tank has a Max temperature of 240 the max temp for a typical boiler is 200 but usually doesn't even exceed 180.

NO

Valve under the air vent isn't necessary.

I was watching this video after my spirovent 1-1/2 inch was replaced it was 20 years old. I live in canada its hard to find the spare parts to replace this and it seems like mine was not worth fixing by replacing the head. I've heard older versions are a lot harder to replace? ended up replacing with a Calefactio one by our plumber. $800 as the calefactio itself was worth $300. I like to save money, but not sure if I could of really saved a lot by replacing the head. If it had a 20 year warranty how could they verify the purchase? hard to keep a receipt after 20 years haha.
