Dry Charge Install

Hey guys,
I know how to do a full install of a factory charged a/c, however, I only put in a couple of dry charged units and feel like I'm forgetting something. My question is: What's the best...

Depending on the length of the vent and the number of elbows that are in it (each elbow = 5' of straight pipe) you may need to consider a booster fan. Otherwise you're on the right track, just...

410 is more "touchy" than 22, you can't really just hold the suction line and wait for "the bite" to come. But you do need to charge it as a liquid instead of a vapor.

The size of that furnace should be enough for the size of your home. If you're finishing the basement I would assume that there would be some sort of duct work involved so that should solve your...

While you're there pull out the limit and feel inside to see if your heat exchanger's cracked. My company's replaced about 10 of them on the 80%'s in the past year.

Is there room for you to mount it on the return and run the bypass to the plenum? Either way, having the bypass or the humidifier itself on the door to the coil cabinet will make it slightly more...

Your furnace being replaced shouldn't have anything to do with your coil, they are two separate systems. You should be able to get a new furnace installed while leaving the existing coil intact.

Sounds like a possible open high limit switch... Check to see if there's 24vac across the limit and also check your filter to see if it needs changing.

Make sure the sensor isn't touching any of the burners or other metal components within the furnace. It will ground it out and cause it to not work.

You could try turning the flow down a little at the valve in your water line. You only need enough water to saturate the pad.

You could use hard pipe instead of the flex if that's possible. Flex pipe has higher resistance to airflow than hard pipe would. Or a simpler solution would be to try partially closing some of the...

A cracked heat exchanger could cause flame deflection, however it'd have to be a pretty substantial crack to completely extinguish the flame.

It could be the blower wheel itself, not the actual motor. It may be out of round and rubbing on the housing. I've also seen the squirrel cage portion physically separate from the wheel hub.

Check the collector box as well as the hoses running to and from it. Make sure they are clean and unplugged. Also make sure that there's nothing blocking the exhaust outside.

My guess would be that there's vibration being transferred from the furnace to the duct work. See if there's any unsecured pieces of duct or if the blower is vibrating.
