Why is my a/c weak every time I turn it on for the season?


Reclaim = recycle the freon, a log book is kept so the EPA can see what is being used VS what's recycled.
Blown out = using an inert gas (nitro.) to remove any impurities( air, dye or whatever) from the system.
Vaccumed = Making a cavity for the freon to fill devoid of atmosphere
Refilled = New freon
Where u got your info = A little bird told you, allways worked for my Mummy.

Why is my a/c weak every time I turn it on for the season?


I contacted my so called pro HVAC person, and he said that it would take him 4-5 hours to locate a leak.

What he did so far was come over and top up the freon, and told me to keep an eye on it.

He said he doesn't have the equipment to check other than soap.
(It's too expensive and he has only had to do this 2 times in the past 5 years)

How long does it take a professional to locate a leak if they have the expertise and the tools to do this?

I'm getting really because it seems he is just giving me the business.

I would like to seek elsewhere but don't know where I should start.
Yellow pages

And how would I know if this new person would be any good?


Thanks

I've spent quite a time finding leaks that were not in the coils but in the refrigerant lines- between walls and the infamous top plate or a nail that was touching the copper and finally corroded a hole in it.
These can sometimes be found placing the leak detector tip into the wall cavity, then one must decide if he can knock a hole in the right place to find and repair it or replace the copper between the wall (or run a new one outside the wall).
The last one I had ran between floors- I isolated the lines and pressurised them with nitrogen for 4 days and noted the drop in psi. I replaced the copper lines thru the attic and down a wall.
All you can do is call another company, explain what you have and ask if they have the proper equipment to locate a problem leak.

Thanks Mrtech.

I think I will contact another company.
The problem is how do I know that the guy is going to be any good?

He did state to me that he noticed some oil.
Would that not indicate to him some problem where the oil is?

I'm no hvac tech but I'll give it a shot.

First off, if its low on freon there is a leak. Period.

" reclaimed, blown out (nitrogen) vacced down, and refilled"
If its low, not empty, this is the procedure.
Remove (reclaim) the old freon, Fill with an inert gas (nitrogen) and pressure test, check for leaks, remove the nitrogen and refill with freon after the leak is fixed.

If its completely devoid of any freon then the reclaim step is not done. I am having a problem with cooling at the moment too. TBD when I'll get someone out.

Thanks brik.
I don't think my HVAC guy really has the knowledge and the equipment to help me.

I have to look for someone else.

Only problem, how do I know if they are any good?

Hi Yummy
Your (dude) could buy a flame tester, an electronic detector,and an alternative light source all for less than a grand, not too much moola.
Sounds like he may not have a reclaiming compressor and tanks, or a vaccume pump, heck, throw in a torch, write off the SUV and anybody could be HVAC dude (dudet) for less than ten G's.
Gauges and freon does not an hvac dude make!
He says 2 leaks in 5 years, how many top offs (say it with me) looooossssserrr!
Wish I could give you some advise on finding another dude (dudet) but I mow the lawn on the other side of the fence, if ya know what I mean!

You're funny

He said that the electronic tester costs approx. $700.00
He said it's not worth it, because he only would use it very little.

I think I will look for someone else.

Thanks mikemy6, you have a great sense of humour.
I have to look for someone else.

How about you jump the fence, and come and help me.
I will contact some friends and possiby get some referrals.

Wait till I start asking what tools these new guys have.
I don't think they may even want to come and see me.

Im back
I like the way he said you should keep an eye on it. Right, left, or third? Maybe he thinks you'll wip a set of gauges out of your whoha!
Sorry I forgot you had a question, if you have a typical AC as in open lines in the cellar, A couple hours to find and fix. I like to pressure test overnight, then a couple, three hours to vac. and fill.If you have buried lines (in the wall) of course more time and as they say time is money!

handy man;
your mind is in the gutter.
But, seriously I am going to ask what tools the next guy uses to detect leaks.

The lines are not in the walls. All are visible as the basement is still not completed. He has complete access to the lines.

He also told me to buy a thermometer, and put it on the vents and check and see if the temperature changes over the next four weeks.
Can you believe that. He said that it should read (the cold air coming out) about 17 degrees celsius. If it starts to increase then call him.

If ya stick that thermometer up his ass for 4 weeks what his temp. in celcius? O thats right you've got nothing else to do, I take it back, Ill send you mine I just gotta yank it outta (pop), no worse for wear. I always have my clients buy my tools, cuts down on the overhead cost.
Next year Im gonna give new meaning to DIY.
