    I swear this guy is just the best I could watch his videos for hours and hours he has so much knowledge to share I wanna try to absorb every bit of it. Thank you so much Jim.
  • @smacleod69
    I laughed so hard when he said the filter dryer is a muffler for the lineset! hhahaha
  • @JesseStarrPhoto
    I love Jim’s speaking tone. :D. Thanks for this. Good info.
  • Very concisely laid out so its easy to understand like that he simplified the verbiage so you get the basic understanding of the flow before the deep dive into the internal mechanics just started the course for HVAC on the learning portal and these vids are awesome help for a person like me with little experience but great desire to learn
  • @SwingTrading
    thats not a muffler its a filter on the outside unit. Great video though
  • @raissawdantas
    Buying my first house soon!!!! These are so helpful, thank you :)
  • @Encourageable
    The guy that did yearly service on my AC poked a temperature probe in the ductwork above the air handler to check the temperature difference. Seemed like a good idea - but he never attempted to cover the hole so I just put a little duct tape over it.
  • @terrence.b
    That's not a muffler, its a "Dryer" it keeps moisture out of the lines
  • @sultandamani9069
    If Outside temperature is above 60, should we check the Hot Mde
  • @sultandamani9069
    Can we make opinion regarding Tonnage according to Sq. Ft. Of House??
  • @fredlamont9076
    Also didn't check system pressures, compressor amps, reversing valve operation/heat strips/furnace heat operation, filters and inspect duct condition/connections. You get what u pay for.
  • @lgc3763
    *filter drier in liquid line, mufflers located in discharge line if there is any
  • That's NOT a muffler outside by the condenser it's a liquid line dryer which is designed to absorb non- condensable's in the refrigerant.

    Delta T should be 16-22 degree diff.. not 13-16..
  • @davidallegro3395
    Dryer filter, 18 to 20゚ split, This guy said multiple things incorrectly Not a very good Inspection didn't check the freon level didn't check the Coil if it's Dusy or clogged. Didn't open the panels and check the wire connections didn't check the capacitor Wire breaker terminals. Drain line could be partially Clogged.
  • Hire an HVQC professional. Not a clown like this guy. Home inspectors are the mall cops of the real estate industry
