  • Paul Rhodes replied to the topic 'HVAC service decision tree' in the forum.
    The only version I've run across of this type of info was in the book "Modern AC and Refrigeration" (Goodheart-Willcox publishing; 20th ed). Appendix B has a pretty good basic trouble shooting chart.

    Since very few Apartment Tech's have that book, I teach troubleshooting based upon this statement:...

    Happy afternoon David,

    You are correct in the method of determining proper amount is specific to the system design:

    ---Superheat is used for fixed orifice metering device systems
    ---Subcool charging is used for systems that have a variable metering device (TXV or TEV)
    ---Weigh in charging is the...

  • Paul Rhodes replied to the topic 'MO99' in the forum.
    The charging adapter I have is sold through various suppliers and is called an "Insta Charge" fitting. Essentially it's a metering device that is threaded (1/4inch flair) to fit between the manifold and low side hose in line to allow the refrigerant to change state. Alternatively it can be installed...

    If I can add on to your timely reminder, Maintenance Technicians need turn off the radio,or shut off the phone and put down the caulking gun during this time of day as much as the office staff. I've found (and am also guilty) that maintenance technic

    Thank you for the compliment Perry,

    Yes, I'm sure. Section 608 until recent changes has always been directly about protecting the Ozone layer. New changes take the focus away from ozone layer protection into decreasing Greenhouse Gases since all currently useful refrigerants are at their heart:...

    The quick answer to your question is "as needed" with a corollary statement of "they are currently not cleaned often enough."

    The challenge is that this procedure can be time consuming due to the vast variety of challenges encountered to do the job. Here are some thoughts for the situation...

    Happy Holiday's Kurt,

    Welcome to the wonderful world of writing for Maintenance! I've been writing various maintenance related articles for one publication or another over the past decade. A couple of tips I would pass along for any topic that you pick to write about are:

    - Tailor the topic to...

  • Paul Rhodes replied to the topic 'It's in the bag, man!' in the forum.
    I really like this idea with two minor changes... If I was interviewing in this method, I'd ask the experienced candidate a specific service request (replace a three way switch, or drop a garbage disposal for example). This way if the technician is as organized as Perry infers he is and has a bag...

    Loving this topic!!!

    I'm nodding my head with every comment. In my past, worked on properties and handled service requests in a variety of fashions. From no S.R. documentation to being required to write an encyclopedia for each need and repair. In my opinion the service request is best handled...

  • Paul Rhodes replied to the topic 'Where do you find good maintenance techs?' in the forum.
    Trying to find a technician that is already skilled can be a challenge. If the property is looking, don't hang your requirements on only 1 skill or qualification and be ready to be a little flexible. Here are some possible suggestions I've seen work in my travels:

  • Paul Rhodes replied to the topic 'Empty R22 Containers?' in the forum.
    According to the EPA, the tanks that have been emptied of original refrigerant must have any remaining refrigerant recovered (there will always be a little left in the jug). Once this is completed, the container must be rendered useless. This explains the "knock-out" that is on the side of the jug....

  • Paul Rhodes created a new topic ' Air Conditioner Replacements - DOE Final Rule' in the forum.
    The Department of Energy (DOE) has issued their final ruling in regards to the Regional SEER rating standards that are now in effect. If I'm understanding them correctly, it is now (as of 30 days past August 15th) illegal to install a new condensing unit on an unmatched (below 14SEER) air...

  • Paul Rhodes replied to the topic 'R22 dry units are all gone...' in the forum.
    According to Goodman, if the evap coil was made after 1992 and he changed the metering device to match refrigerant and system size, he should be OK.

    Based upon all of the information you have shared, and he for sure flushed the line and coil as directed to remove the mineral oil and brazing debris...

  • Paul Rhodes replied to the topic 'R22 dry units are all gone...' in the forum.
    Shot in the dark since we aren't at the system. If you mean by saying that the "compressor is loading up" that the sound of operation has a drastic change, that could indicate a restriction in the line.

    When the new condensing unit was installed, was the lineset correctly sized for the distance?...
