- HVAC Service Call: PTAC Unit Not Blowing Cold Air (Packaged Terminal Air Conditioner Not Working)
PTAC stands for "packaged terminal air conditioner." PTACs are single, commercial grade, self-contained units installed through a wall and often found in hotels. A PTAC's compressor system both cools and heats. To cool, the units compressor pumps refrigerant to cool the coils which attracts heat and humidity which is then exhausted to the outside. To heat, this functionality is reversed. The refrigerant is used to heat the coils, and when air passes over it the unit pushes the heated air into the room. PTACs are larger than a typical through-the-wall air conditioner; the standard size is 42" wide. PTACs are often seen in the hospitality industry and are approved for commercial use, but they are also suitable for residential applications.
PTAC units are beneficial because they can efficiently cool and heat a room from a single unit. PTACs are commercial grade durable units, but since they are units 42" wide you have to have a large hole cut into your wall. PTACs have to be installed into an external sleeve with an exterior grille that are both sold separately. PTAC units are generally more expensive than window air conditioners, but if you are planning to both cool and heat a room then you could save up to 20% a year on electricity.
All PTAC units require purchasing a grille and a sleeve (unless you are replacing an existing model and your sleeve and grille are still in good shape). Other accessories such as drain kits, hard wiring connections, remote controls and wall thermostats are also available and are usually sold separately. - Věda a technologie
Troubleshooting on point!! No intimidation! Good job 👏🏻
Thank you Michael! Appreciate you watching & your feedback 🙏 Stay safe out there & stay tuned for new videos every week🔧
nice one bro. flawless order of operations. i love that you diagnosed the capacitor before pulling the whole unit out of the wall to get to the motor to check bearings etc. A lot of guys are too heavy handed and would impulsively do that as soon as they realize condenser fan is not spinning. cool cat.
Such a great feeling when you find the fault 😁😁😁
You were right to go for the 4 microfarads as opposed to the 7.2 as its nearer the capacity required.
An easy return visit with the right capacitor and a few cable ties - job done 👌
Keep up the good work 👍
It really is an amazing feeling! 😁 Thank you very much and thanks for watching! 4MFD did the job. Return visit with a 5MFD would be perfection. Appreciate the feedback. Stay safe out there & stay tuned for new videos every week🔧
I just started a new job and this video helped me out so much. I am a new subscriber to your channel and I hope you keep up the hard work. I truly appreciate it
Awesome!! Thanks I work at a hotel with chill water and I have a part time job working at another hotel with PTAC units and this is good information. Love your videos bro.
Informative helpful and interesting video. Great job as always. ⭐️⭐️⭐️⭐️⭐️
Thank you 🙏 for this video! Really well explained.
Love the way you break it down
Great job. Stay safe!
Thank you very much! Much appreciated 🙏

Watched video and it was very informative...Need to make more of these with detailed information..thanks..
Always very interesting informative and educational
Well done man👏🏼
Thank you very much & thank you for watching! Appreciate the feedback🙂 Stay safe out there & stay tuned for new videos every week🔧
Nice video troubleshooting.
Great work bro 👏👍!
You made me remember my beginings in hotels mainance.
It's 1135am and I just watched a video on troubleshooting a ptac unit it was very helpful
Great job man !
JMT at it again! 😎😎
This was great video
to check a/c voltage just put one lead to ground and the other to the voltage?
what a cute little unit
Hey Jumper man, we have a Follett ice/water dispenser where the ice machine stops working all the time, what do you suggest? By the way great video!
Thank you man
That compressor was very very angry when you first turned it on!!!
Good job
Solid performance
Good working
Thank you very much & thank you for watching! Stay safe out there & stay tuned for new videos every week🔧
I'm looking for info on this same unit need to know how to reset the error code
Great video. I have a similair problem in a unit i'm renting out. The tenant says: "unit rarely blow cold air and make a lot of strange noises on and off." I think it could be the capacitor. I ordered a decent multimeter and I'll check it out. Thanks again.
Thank you! That strange noise might be the compressor turning on and off or one of the fans. Be careful testing the capacitor as they can be dangerous and it's best to leave it to the professionals. Thanks for watching & good luck!
Jumper man Tech can he pull the capacitor and short it to remove any charge in it? Short it Common to herm & and then common to fan with a screwdriver with a rubber grip?
@@jakestephen508 Yes, need to discharge the capacitor. They sell a tool for that but you can also short it out with a screwdriver the way you said. Def make sure the handle is insulated. Thanks for watching!
check fans . its probably caked with mold or not turning.
Sweet 👍🏻
?: capacitors can be tested without discharging, is that correct?
Thank you! Capacitors should definitely be discharged no matter what for your safety. Typically these days they discharge themselves either with a resistor attached to it or just when the power cuts off. I made a video on how to check them properly. I'll leave a link below🙂 Thanks for watching!

Good bob
awesome
Amigo porque un ptac me esta quemado el fusible solo cuando prendo el compresor porque en ventilador no lo funde??
mastermind at work
Haha thank you bro! You're the best man😅 Thank you for watching! Stay tuned for new vids every week🔧
this took to long for it to just be a capacitor. thats the first thing ill look at
units looks old as me replace it cheaper and easy
Just have a L in code window
What do L mean in the
