21 Jul 10 HVAC Air Conditioning Safety

Featuring: I’ve had many people email me for technical help with their air conditioners. Walking people through the process step by step over AIM or the telephone can be a real challenge. I have no problem with giving people the knowledge to fix their own equipment. I am concerned about their safety. Telling people how to change their air filter and cleaning the condensate drain just isn’t enough for most of my viewers. It’s time I told people that sometimes you need a professional to do the work.

    @DrZarkloff ..So you think I can get an accurate enough charge by the sight glass so my new condensing units will be properly charged, here is what I would do….I would install sight glass, charge unit until glass is almost clear, let unit run for an hour then top off the charge until glass is clear, take FLA Amp reading…

    I live in Las Vegas, temps reach 115 to 120 in the summer..So if I install sight glass run unit for some time untill unit settles down then top off untill sight glassis clear would I be pretty close to correct charge as if I used to super heat method..Thanks DrZarkloff

    @MrJujubean Yes, you can add a sight glass to the liquid line. It is possible to ball park the charge by using the sight glass as an indicator.

    Thank you Dr. Z,
    your videos always help me to understand different aspects of the trade. I was just approved to take the contractors license exam in HVAC/R, and my code books are on the way.

    It’s a safety practice in the event you were to accidentally touch an energised circuit.

    If the ducts are full of mold then it would be a good idea to replace them. Otherwise, just inspect the duct for air leaks and make the necessary repairs.

  16. |

    Air leaks would allow water into the ducts? Should I replace the ducts?

  17. |

    This is a great skit. bravo!

  18. |

    It sounds like you have some really bad air leaks in the duct.

    Your videos have explained alot. Our problem is we have water inside our ducts. We just noticed water dripping from 2 or our ceiling ducts. We opened them and see water on the walls of the flexible ducts. The A/C has been off since September, its 20 degrees today. Did this water accumulate do to a blocked condensate drain or a probem with the A/C machine itself. Also how do we dry these vents?

    Get real. Wa wa wa. Yes, its got stereotypes, so don’t watch SNL, dont watch this, don’t watch other youtube videos, live a boring life, go live under a rock. Stop getting so offended with, in my opinion, baseless accusations. Go look up racist, see what it really means. There is a Mexican guy posing as a Mexican and a Black guy, he may not be Mexican for all I Know, all I know is if he acted like a white guy this video would probably be boring, this coming from a white guy. Great video! 5 star
