What is an RTU Unit? RTU stands for roof-top unit. All the components, including the coils, compressor, and fan, are packaged into a single unit on the roof. Traditionally, most HVAC systems have some components that exist outside, and some that exist inside.
The RTU HVAC unit provides all the heating and air conditioning needed for your space. The heated and cooled air reaches different areas in the building via ductwork and registers. You’ll also have return registers to pull air back into the system.
Other types of HVAC systems have separate components. In an air-cooled split system, for example, the condenser is typically located outside, and the evaporator and fan are inside. Also, you’ll need a separate boiler or furnace for heat with a split system unless the system is a heat pump.

I know what's wrong with it, it's York they need a better unit.

[@ugeneous]

Don’t waste your time the leak is on the condensing unit. They use the aluminum coils at the copper connection. Every single one of these units leaks in the exact same spot. And if it’s not there, it’s under the pressure fitting on the discharge line right at the compressor. It cracks as well due to vibration.

[@Longeno55]

Wow, those old contractors looked burnt.

[@douro20]

20 ton unit? The way things are going you may not even be allowed to maintain these in a few years...

[@MNPipeFitter]

On those older York boards you can bypass the compressor delay. If you hold the test and reset buttons on the board it’ll let you bypass it. Good stuff!

[@ugeneous]

When you walked up to the unit, the flash code said low pressure compressor too, and then you reset it and did all this extra work but still have not fixed the actual problem

[@Hamasisfilthytrash]

Why not pull the old contractor set the new one then re wire it smh makes life easier way easier

[@robertdavenport9095]

[@Longeno55]

You got the touch (and the experience) bro!

[@mikeclark1756]

With a really low discharge temp . cleaning the evaporator coil is the priority . loved to know what the full load amps on the evaporator blower motor . got to check if you made a follow up video . Thanks for showing

[@ricardogodinez424]

Thank you, Good way to explain how to find the problem

[@jasonjohnsonHVAC]

Sometimes I'll use electrical tape and use that to mark what it is and where it goes. Most manufacturers use a number system with or without a letter as well. Trane is a perfect example. Every wire is black and you absolutely need the wire identification to know, unless you mark it. I just replaced 2 of the 3d scrolls on an intellipak. Everything started up with no issues because i marked the wires and used the diagram to confirm.

[@user-vf3fb1ok1j]

Thanks for all the clarifications. Can you simplify the explanation?

[@cristianbedoya7538]

Thank you
