Good afternoon, central air system, my son is complaining the system is not cooling, clean filter, condenser running, Delta T 10*, on a hot humid day I would expect to see the suction line sweating,...

It’s only on there long enough to help fire the burners to create enough heat for a positive draft .
Geo🇺🇸

Not a lot of room here, plenty of power,

Ok, so we have a small steam powered locomotive that has a propane fired boiler, we need to create a draft from the stack in order to get the burner to fire, we would retrofit the inducer to sit over...

Hi All, where is a draft inducer fan located in a boiler system , I assume it would have to handle flue gases, trying to find an inducer that can handle at least 325*
Any thoughts?
PS , this won’t...

OK! I’ll bite, What fittings are available?

Hi All. Can I switch from 1/4” ACR to 1/4” OD soft drawn copper tubing? for a pneumatic system.

Hi, so I did some investing on a junk bubbler and found that the cap tube is actually part of the evaporator , unremovable , so my guess that the new tube will just get pushed up inside the...

Even with the front cover off the cap tube goes up towards the top and in through the insulating cover which is strapped around the evaporator, seems like the thing will have to come off, looking for...

Hi All, I need to replace the cold control on this bubbler, is there a work around to placing this cap tube without getting up around the evaporator, would getting it around the suction line as far...

The furnace runs for 2 minutes, then the burners & inducer fan stop, blower keeps going for 90 seconds, then it starts all over again, limit switch was changed, good point on checking the temp too...

Hi, unit is shutting off before the set point is reached, checked the obvious, filters, coils, registers clear, seems to be going off on HL, next will check to be sure flue is not obstructed, I did...

Hi, retired tech, the board is a ICM275 board, not familiar with this Bryant unit.
Thanks

Hi All , anyone know where I can find a list of errors for the Bryant error codes, Mdl # 376BAW048095, nothing on unit.
Thanks

I will ask if there was any start up info, but I doubt it because he is not the original owner.

Hi All, neighbor has had 3 compressor failures in 2 years, 1st was the original then 2 others, sounds like the units are basically exploding, they run for a couple of days then fail, I have never...

Hi, how are you controlling the electric heat, is it strip heaters ?
ALL LIVES MATTER!
Geo 🇺🇸

Hi, I am trying to understand the function “E” terminal in a HP system, can it be used to control a gas furnace for emergency heat, my guess is that it can.
ALL LIVES MATTER!

Hi, can you post some pics of what you are seeing, is there exposed copper?

Hi All, trying to find instructions for calibrating the internal temperature sensor for this Stat, we couldn’t seem to find it in the manual, seems to be at least 3 degrees Hi from actual room temp,...

Will static pressure effect the fan speed? does not have a ECM .
No idea how old the duct work is , it’s a condo and all flex duct.
Geo

The system is all flex duct , short piece of metal duct about 3’

Hi All, not sure if this is the right forum but my new air handler sounds like a helicopter rumble often times, new system but the one it replaced did the same thing, could this be a duct issue?
Geo

Well that’s what I thought, just wanted to confirm, I was hoping for an instruction manual for some tip. :cheers:

Hi All, what is the easiest way to replace a thermostat on a model HAC8FSCQ 1C. Water fontain?
Geo:deadhorse:

I would assume the air flow would be the same regardless, , because there would be no change to the duck work,you can only cram so much air into existing duct work,unless I am missing something.

Well that will be a question I would ask the installers,what would be the price difference,I just don't see the need for ripping duct work apart etc. I would think it would be the condenser and coil...

The system was installed in 03, AC with electric heat, still running fine, just trying to plan ahead,really don't see the need for replacing the whole airhandler,electric heat has never been used,...

Hi All, looking for thoughts on changing a condenser and evaporator only,air handler is fine i.e. Blower motor and electric heat,I see no need to rip out all this equipment and install a complete new...

Hi All, is it possible to use a Honeywell RET97B5D1002 to replace a McQuay 665404B-09, I don't believe it is.
Thanks Geo

Hi All, I hope someone can explain the theory behind this installation,my condo in Fla. has a humidistat to control the humidity it is tied in series with Y1 on my Stat ,so that both devices must be...

Hi All, can someone explain the use POE and MO oils?
Thanks
Geo

Hi All, in the event that I may need to replace my condenser my thought is to replace only the condenser because the AHU is fine or worst case replace only the A coil,any thoughts?
Also any thoughts...

Yes, unfortunately it is and I want to install the Buderus power vent if I can determine the part number, Buderus use to have a good tech support forum but no longer, so I will attempt to call them...

I have a Buderus G124 propane fired boiler which I plan on installing a power vent,is there any need to make any adjustment to the boiler?
Thanks

The fact is that the boiler has been fine for 6years until the pellet stove was installed and the door at the top of the cellar stairs is being left opened so the warm air will rise I am thinking...

Hi,I have a customer with a Buderus G124SP boiler and the flue hi temp safety keeps opening on occasion and shutting the boiler down,the boiler is located it a large open basement they have recently...

Hi, can anyone explain how air gets into a closed loop heating system?

Thanks

OK, that makes more sense to me, thanks for taking the time to explain.

Assuming I did have the correct pressure on both sides of the valve how dose the pipe size make a difference ? Dose it have to do with the gas density or something?

Thanks , George (I am an...

Cable is approx.50' and we tried another able with the same result.

Has anyone had problems with false tripping we have replaced the cabling and the control will not reset,looking for other troubleshooting suggestions.
