A friend of mine posed an interesting question to me. With 3 phase reciprocating compressors does direction of rotation matter??

I know that a 3 phase motor must turn int the direction of...

By knowing the cfm by room you can size your duct per room and usually it works out plus or minus. Work a block load in comparison to room by room.

I read your question and think I know what you are after.
A past employer gave me two formula's one for concrete slab the other for house on crawlway or upper level.

The drier is in the suction line. Really haven't opened the unit totally to investigate the installation (Factory or retro on the filter.) The service valve itself is not frosting. There are a fiew...

Believe it or not the drier is in the suction side. I assumed it was a factory installation. Remember though I walked into this situation. My boss took over the account from some fly by nite...

frosting is only occuring from the suction svc valve to the compressor. I didn't check subcooling but will. I do know how to check the reversing valve but haven't doen it yet. As I stated, the only...

I am working on a 3 Ton Heat Pump that is used to cool the parts and tool room of a machine shop. It is a York system with TXV for metering. The filter is clean. The customer complains that it's...

I agree about the quality of the installation. I have installed Ruud, Goodman,Carrier,Trane,American Standard, Payne,Bryant, to mention a few. They're all good and are seceptable to manufacturer...

Your work is neat and well done. I would have had my drain pan suspended directly under the air handler, kind of a two tier hanger using unistrut or l-iron, less chance of condensate drip splashing...

Dakers I wouldn't mind working with you, I take pride in my work and am very picky. The place I used to work at has dropped quality for quantity and speed, the owners got greedy.

I thought they might be courtesy t's not drip legs, you know for future expansion of the piping system

Hvacdr there is a vent on his condensate, havent you heard of putting a removeable cap on it like he did??

Examiner a power vent shouldn't be needed anyway, the lateral run isn't that long, you should know that.

I know what you mean, it should have been in conduit or sealtite, with the proper ends and hung neatly out of the way.

It amazes me how some people get away with shqddy work. I...

Perhaps if they used mastic it wouldn't have ome apart. I also niticed that the panduit wasn't cut off, did they even tighten it? I know code states either panduit or tape to connect duct work but...

Looks like a company of Polocks or Mexicans did the work, maby a combination of the two. How does someone who does work like this keep a licence?

Your photo of the ductwork was a little dark, was that a piece of duct hanging open or damaged?
