I live in the southeast. When my house was being built the builder said the Air Handler would be in the attic. I told him to put it in the unfinished basement. The HVAC guys said thank you thank you thank you. Many years later when I had to have a new air handler, they thanked me for having it put in the basement.
@@bryansimon4072 The 5 minute delay is to prevent short cycling the compressor. It is a nuisance while you are servicing a unit but serves a purpose. Taking the time delay out puts the compressor at risk.
I envy you Ted. The way you are able to sit cross legged in front of the unit. Even when I was working, I had to kneel because of sore knees(I did use kneepads). Good post, hopefully they have you do some p/m.
Notice most techs covered their butts by always recommending doing a PM. This way the customer can't call back with the 'you were just here' excuse when the weak cap blows.
Happy that I live in the northeast and have a basement with a drain where I have my HVAC so techs don't have to hurt their knees and sweat profusely from an airhandler in the attic.
You left the duct tape on the panel switch disabling it, wouldn't it be best to have left it working as it was when you arrived? Or is it just a nuisance and best jumped out?
Make you up some alligator clip test leads for the meter to keep alongside the regular set. I find they come in handy at times, along with several sets of jumpers.
I don’t a call in the attic this summer of new home owners that purchased a existing home . Checked the A/C out got it working checked float it worked properly. Called it good . 2 hours later A/C failed again . Came back and the dam float switch had went out . Must been intermittent failing first time I was there and couldn’t catch it .
Another great video. Thanks for sharing. Go home and get some sleep... Then watch at 19:44 --- 20:02, 21:41 --- 22:25 And come back in the morning to remove the tape on the interlock. =)
Float switch breaks wires to low voltage. When switch is activated by lifting up by water, it opens cutting off wire. Apparently one of the connections went bad and interrupted low voltage. When they malfunction, they act as though there is water in pan
My knowledge is mostly from the roofing business in which I installed roofs, and designed roofs as an RCI registered roof consultant. I learned very Early on that you have to give water a place to go. Now take this to the bank: putting a mechanical device in the way of the water in a drain pan that can fail is just plain stupid. If there was ever a place where the admonition " keep it simple, stupid" fit, this is it. Put in a minimum 1.5 inch line in the bottom of the drain pan and run it to grade with the least number of turns. My condensate line runs right to a catch pan that drains right through my poured concrete floor into the gravel below. I squirt a little soapy bleach into the line exiting my evaporator coil from time to time to kill black mold, because I know that mold likes to form on the inside of plastic pipes. Running a small 3/4 inch pipe through a hot attic to grade is simply asking for trouble. Just because it's always been done does not make it right. It does, of course represent a lot of service calls for the HVAC industry. Maybe thats why they still do it?
I had that reminder last year. The float switch would let 24v to the stat but only enough current to run the stat. As soon as it would call for ac, the stat would die. Replaced the stat and had the same problem cause I thought that was the issue. Ended up replacing the float and everything worked fine
Your tips on electrical diagnosis and the process by which one covers basic things first then moves on are invaluable. Do you have any other channels you would recommend for apprentice HVAC techs trying to get the knowledge base of how all this clicks together?
I dont know about you ted, but I personally don't care for those aqua guard float switches. I hate that the pan will have to fill nearly to the top before it trips. I've also seen many that wouldn't trip on a full pan of water, ruining a ceiling.
Thanks Ted as usual you just seem to know how to fix things. Even if you don't like the brand. Maybe you can give us an update on your trane mini split. And ted maybe you can test out and do a Video on the new trane side discharge units. That are supposed to compete with the gree flex units with the conventional air handler but have side discharge units. Ohh and the Mr cool universals are rebadged gree flex units I took off the covers on the front and the compressor said gree on it. Began to figure that out 6 months ago after watching an install video for a gree flex. But verified this Saturday. So if you get one of those calls on those units you can order parts from gree. Since Mr cool seems to have terrible service. Anyway I wish trane would listen to you. They were a great brand along with Lennox and carrier and York back in the 1980s and 1990s, but sadly today the quality control is lacking with parts made too cheaply and that seems to happen with a lot of companies today.

I have a 2 year old Trane smart thermostat with wi fi. Never been connected to the net and I hate the thing! Can I have a normal like Honeywell thermostat installed on our Trane system?
Probably. I don't know the trane product line, but unless the system uses a proprietary communicating protocol, any conventional thermostat will work. If your system supports multistage cooling or heating, or you have a heat pump, your new thermostat will need to support that. Most do. Sounds like you need an hvac contractor to do this for you, since you omitted some essential info from your question.
Don't like nest or ecobee at all. Honeywell makes a wifi thermostat for 170 dollars that is just smart enough like giving humidity readings and outside tempetures without bieng too over the top or complicated. Who knows maybe Alexa will make a bad comeback don't like them either.
always a good idea to record stuff like this even if you're not going to post it on youtube. could save you from a lawsuit when they accuse you of something you didn't do
