I have no question this is merely a outlet to vent over the ducane unit I attempted to fix today.
Started last week. Called for no A/C by a tenant of a landlord I do work for on his rentals. The system is a 5 year old 1.5 ton heat pump that I did not install (according to the manufacture Allied Air will be 5 year of tomorrow 7/25). I found the outside unit not running and the inside unit running. Checked the system and found complete loss of refrigerant charge and the low pressure switch holding out the contactor. I leak checked and found the system was leaking where at the reversing valve body. Not at a brazed joint the actual body where the tubing meets the body. I informed the tenant I would need to order parts and contact the landlord.
This is where some frustration began Allied Air makers of ducane said the units warranty ended on 7/25. My response was that was based on manufacture date and not date of install which is the norm. they said it did not matter and in fact the repair had to be done and paper work submitted before 7/25. I said hold on it failed before the 5 years so certainly what difference does when the repair is made make. They would not budge.
This gets worst as the reversing valve arrived today form them with one day left to do the job an file the warranty. I put the reversing valve in taking every possible precaution to do a good job (keep it cool while brazing, and kept it clean, cut it out with tubing cutter, brazed back in the stubs while in the vise on the truck to make good new connection) start weighing my charge back in and the pressure switch closes good. Charge system in liq line until cant hold any more until I start the unit (put 3 of the 8 lbs in). Stop charging to put in disconnect. Fan does not work. Great fan is bad. Think to my self pressure must have got high and ruptured the body (valve body should have held up but we all know how great thing are made these days.
Call distributor tell them I need a fan motor. I am told the don't have an OEM motor. I have to install a OEM motor to qualify for warranty. The work has to be done by tomorrow to qualify for warranty. Great off to my truck were I get the aftermarket motor I have in stock so I can fix the unit.
New motor installed and go figure my new non leaking reversing valve does not leak, but the new one will not switch to cool mode. Great now heat only system good thing it is 90 outside.
We are now 3 hour, 3 lb of R-22 and one fan motor into it. The distributor does not know what to say the manufacture has not called anyone back. I will probably try to sell the landlord a dry unit. I have no idea how I will recover what I am out.
Makes me want sell some more ducane unit, how about you. Anyone want to buy one?
PS ducane is made by the same company that makes Armstrong and I think that company is owned by lennox. I don't want anything to do with either of them again.
