Any feedback on the lennox merit series? i have been looking into a lower end line which still has a branded name on it i know its an air-flo unit,i really cant go with payne,goodman ect as most of...

Go to help a good friend do a startup on a heatup system today and when i was configuring the stat there was no outdoor sensor which i know is an issue.There is a honeywell th8320u1008 there,after...

I did take all the hoses off and made sure nothing was inside them,the furnace did cycle two times and then three days later i have the same pressure switch error.

I started a a/c install 3 days ago furnace is a nordyne kg7tc 2-stage that was installed 3 years ago with no issues.While do the low voltage wiring with new stat i deside to start furnace and check...

its a microchannel coil in the air handler?there is a charging chart on the cover of the outdoor unit use that.i have had some issues with charging these but when you get it right you will fine and...

i figured as much and its 7/8 after that to the coil

Did a pm on a trane system older 4 ton txc coil no txv and a 3.5 ton r-410 4ttb outdoor.the line set was just under 50 feet at the coil its 7/8 suction but the last 8 feet to the condensing unit was...

Thanks for all the good info,i am running into alot of systems that the airflow is either way to high or set on low speed and with days of 90 degrees an above a system not set up right on...

So if i have a 2 ton split system r410 with 700 cfm across the coil system charged correct with a 18 degree temp drop across the coil and i adjust airflow to 900 cfm adjust charge and have a 16...

This is a straight cool system,the customer called after having a few days to think about it and said they understand this is a roll of the dice.another point i need to bring up is the outdoor unit...

according to the paperwork that came with the coil it uses the same txv for 2 thru 3 ton coils,its a aspen slab coil and the customer called and is willing to try and i mean try what ever i think i...

Is the coil a new c7 microchannel cased coil and if so did you add a txv or use the piston that came with the coil?if its a piston is it the correct size as i have a few of these out there and in the...

pressure dropped 4psi air temp only dropped 1 degree though

They totaly understand i am only going to offer maybe something that might work and it will be in writing/also i do see alot of systems around here with a 1/2 ton larger coil.

i put airflow on low and adjusted the charge that was my first move

i am leaning towards a coil change,it cools to 74 degrees at an 83 degree and under outdoor temp so i just need a little more cooling.

Nope its a 2 ton condensing unit and 2 ton ac coil

I was brought in as a second set of eyes on this one.Got a 2 ton r410 txv system 10 degree s/c 13 degree s/h with a 15-16 degree temp drop across coil.the system will only cool down to 74 degrees on...

The physical size is not right,i do remember seeing a lennox coil with a different style orifice.

That orifice sure looks like all the standard ones i have is it in fact bigger than that

Does anyone have a part number for a aspen flowrater orifice?i need around a .59 its for a 2.5 ton coil the standard orifice i have are all to small and maybe a vendor i can get one

How much pressure should be in the bulb i broke it off on the bad one and there was very pressure,and i do not like the ones with the copper eq line stainless ones from danfoss seem more trustworthy

This was a parker valve and i do agree i am seeing more txv issues recently also.
