Sorry guys about not responding.

The issue is there is a back family room under a flat roof. I have to run ducts across the roof to get supply registers in there.
The existing duct work that come...

Hey guys,

I'm designing a duct system for an RTU. I need to utilize the side openings on the unit, in order to run ducts across the roof. Currently, the duct work come off the bottom of the unit,...

Yes. 55 psi at suction access port. Runs good during the day. ( or both times I was checking it) problems occur at nite, when temp drops.

Didn't check that. I had my hands full working on other system at the time. Amp draw would be high on a comp that was eventually going to open on overload?

[QUOTE=Brent Ridley;14865541]Give us a little more info. You say pressure were good - What were your pressures? R22 or 410? Split or package? Outdoor temp? indoor temp? What's the model and serial? ...

Hey guys,
Hoping you could steer me in the right direction. I'm working on a heat pump in heat mode. Pressures are good while I'm there. Indoor coil clean, blower good. Issue is compressor is...

My company is bidding on a big apartment complex job-replacing about 180 gas pack RTU's. Problem is the crane will not be able to access about 1/3 of them. Which means we would have to wheel them on...

Changing out a bad compressor today on a Goodman 410 split system. Low side running at around 150psi / 50 sat temp with about 8 superheated. High side 425psi/130 sat temp with 10 subcooling. Brand...

Thanks guys,

Interview went well.
Took small written refridge test that was about basic stuff, then took a "let's see if your a serial killer" computer test. I had to "agree" with the last...

Hey Guys,

I'm interviewing for a commercial job tomorrow. I currently work in the residential field, service and install.

Any suggestions or advice? How much harder is troubleshooting bigger...

Fixed the problem. Due to the location of some of the boiler drains (above the boiler water line) it made bleeding the loop a little tricky. I think the other guys where leaving a little bit of air...

Problem started after new boiler was installed

They bleed it with a hose. There's no bypass. And there's no seperate water feed.
I've done loops before using 2 B+G flo-controls, with the bypass going into the 3rd port. And I also would install...

Two story house has two zones. 1st floor is typical one-pipe steam with radiators. 2nd floor is hot water baseboard. The loop is piped into the boiler. It comes out from a port below the waterline,...

He has had guys out there that bleed the loop(3/4"baseboard) get it to work, then the next mourning it's air bound and not heating. He also gets steam flashing through it and water hammer. My thought...

I have a customer with a steam boiler that has a hot water loop off of it. Problem is that he keeps lossing the water to it. It's a two story house. I think he has a leak in the loop somewhere....

Does anybody know how to change the gaskets on Yellow Jacket SealRight quik connectors? Also any tips on how to get the gaskets out of my refridge hoses? Thankyou

Hey guys. I just interviewed for a new service tech postion. The pay rate will be 20% of each invoice. I'm used to getting paid by the hour. Does anybody out there get paid on a percentage basis?...

Do u close the door to the basement when ur in there? R there any returns down there?

Do u have the tools/equipment required to install a TXV? Cause u'll need a lot - vacuum pump, nitrogen tank, guages, torch, etc. Do u have an EPA card, to purchase r-22? Do you know how to charge a...

You already have an efficient system don't mess with it. Save your money.

I usually connect my guages to the system before I turn it on, to take a standing pressure reading. If it coincides with my outdoor temp. on the P/T chart, I rule out non condensibles, correct?
...

Thanks for the help. I'm always reluctant to think something is wrong with the major componants of the system. Especially when it's refrigerant related. Who likes to pump down the system and open up...

If it happens when the boiler is on, and the water is getting hot, then the expansion tank is shot. If it happens while the boiler is off/cold, the the pressure reducing valve is open and feeding...
