Hello and thanks for using this service, if you have been waiting do not worry or get upset. I am HVAC Guru an extremely experienced tech on the site and I try to get to as many customers as I can. I just picked up your question now. NOTE it takes time for me to type research and add links so please wait for me to respond back I can only do this so fast. Secondly I am not paid anything until you rate my service good using the STAR RATING LINK at the top of your page, the money is paid to the site not me directly.

Are you saying the lines are icing back to the compressor?

Customer: replied 5 months ago.
it is icing back to the compressor
Expert:  HVAC Guru replied 5 months ago.

The unit is likely low on freon and will need to be recharged.

All I ask is please use the Star Rating Link at the top of your page before leaving, that is the only way I am paid anything through the site and that will also get you a DIRECT LINK emailed to you to get back to me!.....tips are greatly appreciated so thank you very much for using this service. If you have any other questions just post back to me here anytime!

We have a sight glass by the compressor. When the system defrosts should I see bubbles if it is low on freon?
Expert:  HVAC Guru replied 5 months ago.

When it is running you should see liquid freon flowing through it, if it is icing like that it is low. 99.9999%

I respect your opinion but would like a second opinion and am will to pay for it. Can you arrange that for me?
Expert:  HVAC Guru replied 5 months ago.

Why dont you just get a pressure gauge and see what the pressures are on the system to see if the unit is low on freon or not that would be the best way to tell. If you want another tech just rate my service and this will be posted out to other techs

I did deal with another tech on Just Answer who told me that the problem could either be low freon or not enough return air - clogged evaporator coil or clogged return filter... The problem was not enough return air. How do you suggest that we proceed?
Expert:  HVAC Guru replied 5 months ago.

In your question you stated the return air was clean.

Customer: replied 5 months ago.
I checked through the conversation and couldn't find that I said that. Even if the filters were currently clean,the coil could be clogged.with dirt.
Expert:  HVAC Guru replied 5 months ago.

OK I am taking it you do not want to credit either of us techs take care.

Expert:  Gaztech replied 5 months ago.

HI my name is ***** ***** I will take over to help you with your issue.

Are you ready?

Customer: replied 5 months ago.
Are you sure that this is your answer to this situation, insulting me? You overlooked the possibility that turned out to be the problem.
Expert:  Gaztech replied 5 months ago.

I am Luke, another tech, lets start fresh OK.

Expert:  Gaztech replied 5 months ago.

Not Overlooking and putting priority on the air restriction issue was the best response, can I assist you with that?

Customer: replied 5 months ago.
Hi Luke, The problem is solved and I appreciate your help. It was an air restriction problem and the place was 62 degrees this morning, with no frost.
HVAC Guru said that he was 99.999% sure it was a low charge. I was just trying to give him an opportunity to say that he didn't help me and let's forget the whole thing -credit back his charge. .
No harm was done. Instead he became defensive and rude.If it is OK with you I will rate you tonight when I am finished with work. I appreciate your help and, off course, will give you the great rating that you deserve.Peter

Best regards, ***** ***** for other tech's inappropriate response.

Hi Luke, I know that this is not your situation, but am I also being charged for the other tech? It appears that you took over for him, Is this correct?Thanks,
Peter
Expert:  Gaztech replied 5 months ago.

Hello Peter

You are not charged twice for your question. this is a issue that needed to be resolved correctly and that is why I stepped in.

BTW. is you furnace hi efficiency Gas?

Customer: replied 5 months ago.
it is a 95% unit. Thanks for your help
Expert:  Gaztech replied 5 months ago.

Ok you will need to inspect the secondary heat exchanger for restriction, it is accessible by removing blower and just above that will be it, it looks like a radiator coil and tend to get blocked, if it is use a brush and vacuum to remove all deposits

Thanks, ***** ***** your reply. I will look into this. This AC unit is in a 700 sq/ft store that has a kitchen with a commercial hood.
The company that designed the hood installed a make-up air duct with 4 x 90 degree bends that was much too small without the bends. I actually bought an Anemometer to measure the exhaust and make-up air. The exhaust was 1900 cfm and the intake was 700 cfm.The furnace is at the back of the store. When they run the exhaust no air gets to the furnace and that why it iced and that's why the filter was clean.
Expert:  Gaztech replied 4 months ago.

Imagine that!!

Good job, just goes to show that there is all kinds of issues with all kind of causes.

Best regards

Luke
