Thank you for the educational videos. My AC might as well be a big question mark behind a door in the hallway. Had an emergency and after watching your videos- it saved us from making an expensive emergency call out. It looks like our AC unit was installed WITHOUT a drain pan! The condensate line got backed up and water started to drip down onto the hot water heater below and the ground to the tune of about 2" inches! Shop vac saved the day- however I now have damaged sheet rock & damaged plywood that supports the AC above the water heater! Why ACs are installed without a cheap water detection alarm is beyond me. A $20 - $40 alarm is certainly worth the cost versus the hassle I just went through @ 1 AM! Thanks again!

Hi Doc, Great Videos! Any videos coming up on TXV replacements/adjustments?
Thanks!

After watching this video on megohmeters, I started looking online to buy one. I see that they have analog and digital. I've seen analog, digital,all different brands as well as different voltages(50,100,1000,5000),,,,,,,,,and now I am overwhelmed with info. What types do you like as far as megohmeters?Brands and voltage levels.
I am getting into hvac a little late in life, but I love it and can't ever get enough information on these subjects. I really enjoy all of your videos, thanks for sharing all of your experience and knowledge. I wish you were teaching at my school in Indiana because I would be learning much more than I am and I would be enjoying it ! thank you !

Nice videos. I'm getting into this trade for my career.

Know any computer software that can determine Pressure / Enthalpy that is a good program and would you know the link?
