@kolocho7777 It can be cleaned in place as long as you can get to both sides of the coil for cleaning.
July 27th, 2010 at 6:13 pm
do you have to take out the evap coil when cleaning? or can it be clened as it is attached to the system

@pl33618 It sounds like the compressor is shutting off on either a low pressure or high pressure switch.

I had some maintenance done this evening and now my air is not cooling! The compressor goes on then shuts off after a few minutes. all the while the air coming out is not cold? Is it because the compressor needs to dry first?

@thereceman You really should put the door back on to know what the amp draw is under full load. Make sure that you have a clean air filter first to be sure to get an accurate reading.

when checking amp draw on indoor fan motor is it best to put on your clamp and put the doors back on. i went to johnstone and got the same meter you use

July 27th, 2010 at 9:37 pm
a good blast with r-22 will solve that problem
July 27th, 2010 at 9:44 pm

You can work on your own system as long as you have an EPA card or as long as you don’t have to work on the refrigeration circuit.

Is it illegal working on your own AC at home in Florida? I guess the good old day are gone for DIY. Anyway, I enjoy learning from your video. Thanks for sharing your expertise to us viewers.

Personally what would you do if my dog got out of control and wouldnt calm down during a service call? Can you use a vacuum pump? Is that where chiahuas come from?
July 27th, 2010 at 11:42 pm
It can be done as long as you have easy access to both sides of the coil.

You washed the evaporator coil with water. How can you do that without removing it ?
July 28th, 2010 at 12:43 am
You might want to check for air leaks in your duct.

I cleaned the evaporating coil and drain, I’m having a condensation problem on the ductwork and plenem. any suggestions?

Yes. To legally work on HVAC equipment in the State of Florida, you must have a HVAC contractors license or work for a licensee. I don’t know what the laws are like where you live. You might be able to get a licensee to be your qualifier.

I’am thinking of doing some side jobs and I’am wondering to do Preventative Maintenance and Duct Repair on a residence do I have to work under someone’s contractor liscense? I’am Universally Certified.

You should use low loss fittings on the hoses so that you won’t lose so much gas each time you hook up your gauges. Yes, you’re probably low again.

Thank you for your response a few days ago. Our a/c guy came out and I think he had mistakenly let out some freon. He was great, put more freon in and cleaned the coils. WELL… I had a friend come over and he wanted to check the freon. When he unscrewed the cap, cloudy misty stuff came out until he hooked his gauges. NOW… my a/c isn’t working again and is freezing up. Was this supposed to happen and am I now low on Freon again?

That would require a video to show you the right way.
