I just can’t say enough about an app that has become an essential part of my life and the overall operation of our HVACR service team.
I am talking about EVERNOTE. It is one of the best ways to assemble, organize and present information that I have ever seen. Now you may be thinking that I am compensated for endorsing this product but you are wrong. I am compensated by using the product. I use it for training purposes as well. It has a great presentation mode that I use instead of powerpoint slides.
I use it many times per day. It is extremely useful when we have our weekly service huddle meeting.
Below is a screenshot sampling one of our huddle meeting frameworks.
You can easily hyperlink the topics to other notes that have been organized into specific Notebooks.
We also have the essential Notebooks shared with all the service techs. It is feature-rich and the beauty is that it syncs across just about all platforms.
An example list of our company shared Notebooks contain the following topics: Work Data, Parts Information, Site Information, Memos, Policies, Training, etc. In these Notebooks are contained over 500 notes and training presentations. It is easily searchable for specific notes inside these Notebooks.
As we go throughout the week and run across some useful topic to discuss or encounter a recurring issue, we add it to the list for “Monday” and we keep the team informed. It helps us to maintain a near-paperless approach to our day to day business practices. For all our larger digital files that contain operation manuals and other manufacturer information, we use Box, which contains over 12GB of technical information for our team to access.
My wife and I both have the premium version and use it for all our financial paperwork and household business. Click here to for a free trial of Evernote.
Members and guests got to check a fractional hp compressor for good/bad windings at the June 2017 Regular Monthly Meeting at the Middle TN Chapter. Jayson Goff, CMS was the seminar leader and had just returned from a winning battle over Stage 4 cancer. By the way, the compressor was deemed terminally ill by Larry Lynn, CMS and Doug Drake, CM, due to bad terminals. 😀
Dehumidification features are common on residential systems ever since the introduction of variable speed blower motors. The system is set up so that the blower can produce less CFM per ton when latent (humidity) load in the space is higher than the setpoint relative humidity. Slowing the blower increases moisture removal by reducing the sensible load on the evaporator coil and therefore dropping the coil temperature and surface dewpoint.
Special considerations must be taken when installing condensers in cooler climates. During the colder weather, a winterizing valve should be utilized to maintain head pressure. This valve is actuated by a pressure difference between its inlet and outlet. The figure shows a “Winterstat” brand. Other valves may be used such as a “Headmaster” valve. If system pump-down is a desired feature, the receiver must hold the normal refrigerant charge plus the condenser charge with the bypass valve operating ̶ that is, partially open or intermittently opening and closing.EXCERPT FROM “TOOLS, CONTROLS AND TROUBLESHOOTING“, available from the ONLINE STORE at RSES.ORG.

Troubleshooting and servicing refrigeration and air conditioning systems can be a challenging process for both the entry level and experienced HVACR technician.
Regardless of your experience, size of the equipment, or location, to troubleshoot the system it is essential that you have a solid understanding of the fundamentals of refrigeration – including the principles of superheat and subcooling. READ MORE HERE
