DIY Install of Mitsubishi Mr Slim Heat pump
We bought a used Mitsubishi Mr. Slim and uninstalled it from another home in Seattle and have mostly installed it in our own home. It was fully functional when we removed it and we followed the pump-down procedure in the manual to pump the R410a down to the outside unit and store it there.
Now we've got it all hooked up at our new house... concrete slab is poured,
outside unit is bolted to it, the 220v single-phase electrical is run,
inside unit is hung, hole drilled on outside wall, gas and liquid lines are all connected. Drain line and electrical connect are active. The system powers on and appears ready to go.
We sweated the copper lines together - we had to cut them out of the old house. Got lucky and the refrigerant lines were a little longer than we needed so we kept some extra but removed about 6 inches of each. No right angle bends anywhere.
Now it is time to pump the air out of the lines and release the coolant.
We dont have a vacuum pump/gauge set up and they are expensive to
buy for a one-time deal... plus, we feel like it would make sense to have
a professional do this for us. We're not keen on releasing R410a in to
the atmosphere... its environmentally bad and expensive to replace.
So finally, the questions:
1) What should we expect to pay for a service call to visit our home, do a vacuum procedure and check for leaks, then release the R410a from the outside unit in to the system lines? (Seattle, WA)
2) Can the tech check to make sure that there is enough R410a? how does this work?
I realize this is a tough crowd in here, go easy on us, we're newbies, but
thanks in advance
