43 psi is correct at aprox. 8' of lift you will have ZERO pressure.

Remove all the refrig before you fixed the leak or did you pump it down and then pull a vacuum on the line set and coil?

@ March 21, 2014 10:42 PM in Freon leak vs. moisture

On a job many years ago at a Baush and Loam lab that made eye drops. The lab had to have a very low humidity. There were actually two A/C units and evaps were one in front of the other. The discharge of one into the supply of the other. Well the RH was still to high in the room and the job was done as specked. Some real smart guy came out and explain that even though the supply duct to the lab was pressurised moisture was entering the duct. We sealed the supply and the job ran as designed. And I don't see the difference between air pressure and refrigerant pressure.

@ March 21, 2014 1:49 PM in Freon leak vs. moisture

I would think that vapor or moisture pressure would be the controlling pressure here and not system gas pressure, Since the system piping is dry and the outdoor air would normally have a higher moisture content I would think that moisture would enter the system even on the high side..

Pilot burner flame when the main burner lites. Does it pull away from the bi metal sensor, or does the pilot flame diminish in anyway? It may just need a good cleaning of the pilot. Do not use any thing to poke into the pilot orifice. Use air pressure to clean orifice

@ March 9, 2014 4:56 PM in residential split system shuts down due to overheating

Could be a dirty condenser coil. It may also be low on refrigerant. Most newer outdoor unit 10 years or so have single row condenser coil and all you need is hose pressure and no chems are needed. Some older units have a split cond. coil and you need to remove the top of the unit and clean between the coils.

Making your life way to difficult. Since you already have a lennox furnace stick with a lennox heat pump. If you do not currently have a variable speed blower stick with a single speed HP.You will most likly need to run a new low voltage wire to both the outdoor unit and the indoor tstat. Carrier makes a two wire indoor stat that will work with your old and new Lennox equipment.

The pressure switch is sticking and not opening when the blower shuts off, hence the roll out.
