dr my evaporter coil is freezin up becuse my blower dont turn on, what should i be looking at. sometime it will kick in if i turn off the fuse and turn it back on.
Make sure that you are getting the right voltage to the unit. The breaker could be going bad. Otherwise, the problem will be either a bad blower relay or a bad run capacitor or a bad blower motor.
oh and dr.z there was water on the emergency driain pan under the evap coils, so i cleaned it ,and put water in the drain pan [pan was dry as hell], then it start working again, will the blower not run if there no draining going on
The entire system could shut down if you have a condensate overflow. That’s providing you have an emergency shut off connected to the control voltage.
I didn’t say a low head was an an indication of acid in the system but over time do to high heat can cause acid to form in the system. I tatally agree an acid test kit is the only way to be positive as to whether acid is in the system or not..
I understood what you were saying
don’t you need low loss fittings on you hoses ?
They come in handy.
Do you ever tell your viewers that they have to be certified, by law, to handle or even mess with refrigerant or you could be fined $28,000 and goto jail? All your doing is creating ‘Jack Leggers’ that make it harder for those of us who play by the rules and get trained and certified.
I think that the average person with a little intelligence can tell that this man is a professional, and I dont think he’s creating anything! I think the choice of right or wrong is a personal choice made by an individual, what about all those certified tech”s that choose to do the wrong things themselves. I have learned what to look for when some of these so called “pros” come to my home to rip me off from videos such as this, so keep up the good work Doc, an informed consumer is better.
Nice opinion DaninJonesboro, but it doesnt mean s**t when the EPA shows up and wants to see you EPA card that says you are legally able to handle refrigerant.
Im just giving you guys a heads up if you didnt know. You wanna be stupid DaninJonesboro, be stupid. I’ve seen three guys handcuffed and carted off to jail for not playing by the rules. We get many calls from people like you who watch these videos and get in over there heads, then they call us. I love these videos, they keep me busy after people like you screw their units up.
Thanks for watching.
I think you are misunderstanding the point that I’m making, he’s making informative videos that help me and others that own homes. You seem very argumentive and off point, yet you call yourself a professional. I never stated that I worked on any HVAC components, you need to read Moron and then make an intelligent retort as I did with your first comment. I think your issue is with the man that made these videos and not me and people who just want to know. I say again read, then respond.
Thanks
No problem and once again I thank you for informing people such as myself about the units in our homes. It never hurts to approach a problem with a little knowledge versus total ignorance. I love it when people want to argue over nothing. I’m not a mechanic but knowing how the alternator on my car works doesnt hurt anything when I negotiate repair costs, etc. You have helped me immensely and I am not the only one who thinks that.
How do you connect the micron gauge??
Much like I did in this video.
dr Z can u tell us a little more about the gas ballast on the vac pump ??????
It’s a way for dry air to mix in with the contaminated air from the system to be easier expelled.
i was looking at what southern Diplomat said and was wondering where i can get my universal EPA cert. i mean, it wouldn’t hurt to get it now, instead of after i finish my HVAC school
i watch this video and the whole process its about 4 hours am i right or wrong and your videos are awesome can you say a comment for college of dupage in chicago il because i should your videos to all the students for them to know more practice in real life thanks dr
I show them YOUR VIDEOS SORRY FOR THE SPELLING
It could take four hours on large systems. It all depends on the CFM rating on your vacuum pump and the length of time that it takes to get the system down to 500 microns.
Johnstone Supply gives the exam.
How can i charge refrigerant to Heat Pump in Winter when It low refrigerant? Thank you
