Car overheating and ac blowing hot air Videos

DO NOT TURN THE UNIT OFF AND ON TO GET COLD AIR TO BLOW. It will possibly cause more problems. Turn it off and have a tech look at it. In the mean time use fans to cool down your home.

Ours used to do that. I am not tech savvy with this kind of stuff thats why im here but whenever ours started blowing warm/hot air we went outside and check the outside unit. Our pipes were frozen. So we turned the ac off. After a few hours we checked the outside pipes again, they apparently thawed out and cold air started blowing again BUT the pipes will refreeze and warm air will start blowing . If I can remember correctly we was told there may be a leak in the system therefore the freon/refrigerant was low.

No need for belittling just because you don't agree. It does not make you look smarter only like a person giving insults. This has been my experience out here over ten years hard labor in my area with even newly installed air conditioners that they often need a hard start kit. I have had numerous condensers that three days or so after the brand new install unit compressors sit and hums overheating but not starting. Added the hard start kit and no more problems. Period. I am in building maintenance so if the unit goes down I get the call back on each system.  This gives me a unique proving and testing experience over time. I do not charge anyone for parts, refrigerant, or labor.  my position being a bit different than traditional HVAC guys. I have seen the hard start ease stress on start up and help premature burn out of components. This has been my experience. 

+KungFuMaintenance But I just don't understand how that justifies the need for a hard start kit..... Especially a new install! Assuming the install isn't a hack job than you should check your charge with superheat and subcooling. Always do it the right way because cutting corners just turns around and bites you in the ass. Also not shown in the video but if the compressor doesn't start but is hot than it may be on an overload. Cool the compressor off with some water, evaporative cooling does the trick ;) I've seen units have issues having a hard start kit when it doesn't need it, just letting you know. Always check the amperage of the compressor when deciding to do so. Initial start up amps and running amps. If there's a problem unit than record your "normal readings" on the inside of your data plate in sharpie so you know later.

+Rob HVAC Excellent! ~ For sure we all go further, accomplish more, with purpose in America and beyond!

Ok. For some reason I thought it was an old fan coil with a water coil on top.

+talyn875 To make this clearer. The old ones were 2 ton 10 SEER Coil and 2 ton 10 SEER Condensor. The new ones are 2 ton 13 SEER Coil and 2 ton 13 SEER Condensor. Been working good for three years and now has been three days since adding the hard start kit. Today was about 108 degrees outside and right now  is about 95 degrees outside. For sure I would have been called back if there was any problem (and/or will be if there is any future trouble Lol but I am confident all is well there). 

+KungFuMaintenance perhaps the mismatch is causing the evaporator to flood putting stress on the compressor. It's hard to charge when you have a small 10 SEER coil.

+talyn875 Not too long this one is on a single story flat built up roof system on a platform directly over the air handler.  Perhaps six to ten feet. 

+KungFuMaintenance thanks. Long line set?

+talyn875 I don't mind. Enjoy the conversation actually. This one was I believe about three years old. I had the coil replaced at the same time. Both 2 ton units. (2 ton coil and 2 ton condenser) Matching the old condensor and coil size. The old ones were ten SEER and the new ones thirteen SEER. My air handlers are First Co. evaporator coils use capillary tubes (fixed orifice) no TXV having hydronic heating coils (on Raypac boiler systems) above the air handler. Most of my units are 2.5 ton condensers and coils but this one and some others are two ton systems. 

+Jim Rodriguez At that point I was just thinking out loud a bit while evaluating the system. Not really making a definitive statement there just getting going.

+Billy Knoth I have had numerous condensers that three days or so after the brand new install unit compressors sit and hums overheating but not starting.

+Billy Knoth It's not just you. I was just thinking out loud a bit while evaluating the system. Not really making a definitive statement there just getting started. Lol.

+T&N Services LLC. I am convinced it would not be very easy to impress you. I have enjoyed quite a few of your videos. Anyway. You might check me vid " How To Save A Hummingbirds Life" I do make more than just AC vids.

+Mike Powlas Goodman has a good name already. Their products stand on their own merits and longevity. Just look how many Janitrols are still around.  I have had numerous condensers not just Goodmans in my area that three days or so after the brand new install unit compressors sit and hums overheating but not starting. Added the hard start kit and no more problems. Period. I am in building maintenance so if the unit goes down I get the call back on each system.  This gives me a unique proving and testing experience over time.

+KungFuMaintenance you are correct. We need help each other.

+Rob HVAC It is the free sharing of experiences, creative works,  and information that keep Youtube a good name. It is the teardowns, insults and bullying that try to give Youtube a bad name. The free sharing of the experiences, ideas, processes, thought, art, music, collaboration, creativity,  all of these and more add to the value of Youtube, Life,  and the Internet. 

+KungFuMaintenance you can email me anytime at [email protected] if you ever need to ask a question about anything. If you are interested.

+KungFuMaintenance how old was the goodman? What is it matched with inside? If you don't mind.

 Reviewing this one further it is possible on this one that it was just a Southern Ca energy savings event turn off though when I arrived the light was solid green no blinking indicating that it was not an event according to the box.  As far as adding the hard start kit it has been my experience out here over ten years in my area with even newly installed air conditioners that they often need a hard start kit. I have had many condensers that shortly after the brand new install unit compressors sit and hums overheating but not starting and I get the call out. Added the hard start kit and no more problems. Period. I am in building maintenance so if the unit goes down I get the return call back on each system.  This gives me a unique proving and testing experience over time. I do not charge anyone for parts, refrigerant, or labor.  my position being a bit different than traditional HVAC guys. I have seen the hard start ease stress on start up and help premature burn out of components. This has been my experience. The units that sit and hum not starting takes a toll on everything the contactor capacitor compressor breaker all experiencing the heat and stress of trying harder to get going during that initial start up draw.

+Joe Shearer all late model Goodmans have scrolls in them.

+talyn875 it kinda sounded like a recip to me

+Joe Shearer it occurred to me that could be true. If the Goodman is a few years old at least.

+Joe Shearer too funny.

Unless he inadvertently fixed the unit because it was a recip with a txv! Lol

+KungFuMaintenance if you have any questions please ask.

Real quick, you yourself +KungFuMaintenance said the indoor unit was not on.... If you push the Contactor and the unit runs and you feel the line... How can you assume it might possibly be low on refrigerant? The blower not running would affect the pressures and line temp. ...

+KungFuMaintenance Would you rather we never watched this? Basically should we get lost or do you want to learn HVAC?

+Stephen Rardon Glad to see the whole gang is here. ~ Welcome back!

+Rob HVAC good man Rob. Let's do this thing the right way. +KungFuMaintenance check out the guys in this thread. They have a lot of knowledge to share if you want it.

+KungFuMaintenance if you want to learn the right way to do things join in the conversation. Maybe you never had a good teacher to show you the right way to do things.

I see a callback in the near future...

+Billy Knoth the guy does not know what he is doing.

+Mike Powlas you got that right

+Mike Powlas and is it me or was he trying to say it may be low ... Pushing the contactor in... And indoor unit not running? ???

+Rob HVAC I've only watched a handful of his videos I never have been impressed

I don't understand..."I noticed that this unit does not have a hard start ... Luckly I brought one..." is that an up sell on every job? A company I know if a contactor fails.. U need a hard start and that is an extra like $350... It pissed me off to see it in action!

+talyn875 yep I figured.

+Rob HVAC this is one of the videos I was talking about.

+T&N Services LLC. I stopped watching him because he has no clue what he is doing. Gives You tube a bad name.

Amen
