Air Conditioning - problem or not? (A/C not cool)

Dont know if I have a issue or not. I do not feel cool when I turn my air on. I checked the humidity level, it was 48%. The air comming out of the register was 68. Shouldnt the air blow much colder than that? My unit is a 5ton electric ac,heat pump combo. Any advice?

Lots of ifs here. How long have you had it on now?? Filter clean coil clean in side and out. Blower wheel clean. Big copper line by unit outside is it cold and wet . Any frost on the lines by the inside coil. Check temp drop across the coil by it Should have about 18 o to 20 o drop. Lots of time it can take 4 or 5 days to start to dry out the home so you feel cool. 5ton should be large home and run for long time to get the humidity out. Small home short runs drop the temp but dont get the humidity out.
Check it all and post back

I Will Check All Your Suggestions And Get Back. The House Is Only About 2050 Sq Feet. I Was Told By The A.c Contractor We Should Go With The 5ton Because I Have Tall Celings And A House With Alot Of Windows That Face West. The Lowest Celings I Have Are 10feet. My Living Room, Dinning Room And Foyer Have Sixteen Foot Celings. I Have Huges Windows On The Front Of My House That Face West. Do You Think My Unit Could Be To Large? Yesterday Was The First Day I Turned My Ac On. It Ran About An Hour To Drop The Temp From 80 To 75. When It Shut Off The Humidity Was About 45. What Should The Humidity Level Be?

Lets see here a 5 ton cooling system will not get the vent temps below 68f with a assumed outdoor ambient of 80f after operating for over 1 hour hmmm. Houston we have a problem no doubt. I would be on the phone in the next five minutes to that contractor that did your install. It sounds like this is the first time you have used the AC so it could be something as simple as a miswired thermostat or incorrect charge level, how did the heat pump side work in the cold weather????

Sounds like you have a AC load there But if you turned it on for 1 hour And turned off at 75o Id say it to big. Like 5 ton on just 2050sq ft. You want a unit to run so it get the humidity out and you will feel cooler at a higher temp.

What Is A Good Humidity Level?

Well to answer your question about the size. With the tall ceilings and the large windows you could be at the right size but without knowing insulation types and thicknesses I can't say for sure doing a load calulation is the best way.

The humidity level that is strived for is 50%.
With that being said it can fluxuate from 35% to 75% during the cycle.

For the humidity in a home all of my books say the body want between 40% to 65%

My A/c Tech Came Out And Told Me I Have A Leak. My System Had Lost Four Pounds In Four Months. The Owner Of The Company Gave Me Two Options. They Could Isolate The Leak And Fix It Or Insert Some Stop Leak Into The Sytesm? He Told Me That If They Found A Leak He Would Fix It. The Only Catch Is If Its From A Nail Hole Thru The Sheet Rock The Bill Would Be On Me. Any Comments On The Stop Leak?

I dont think we have the whole story here.

Is this a new AC unit???? Did you dry wall around it ????

No stop leak . Find the leak and fix it for sure. A 1lb a month,if its been cool up there and the AC off Id look at the big copper suction line first.

The House Is One Year Old. They Have Been Out Four Times Now. Im Not Sure But I Think They Have Added Freon Before. I Guess I Have A Small Leak. I Hope Its Not From A Nail. But How Could I Protect Myself, They Could Tell Me It Was A Nail And I Wouldnt Know If It Truly Was.

Hey one year old and have been putting freon in it Id say its all on them. Dont let them put stop leak in here yet. Find and fix the leak. If all they do is keep putting freon in it at 1 lb a month. Say you are going to call the EPA and ask them about this also might call the BBB there.

Not sure what the EPA says but MOPIA up here in Manitoba says they cant top up a system unless they found and repaired any leaks. They should have fixed the leak last time they were out instead of just "topping it up".

If you wanted I'm thinking you could have them in a whole pile of dodo if you needed to. If it were a nail hole My guess is the whole charge would be gone.

Ask to see where the leak is before they repair it and if possible take photos of the location. Be sure they do a pressure test/vacuum test on the system as well.

To many windows, can't cool your home, board all of them up and see if your house gets cooler (smile) just poking fun
The guys here gave you good advice as usual

A good electronic leak detector like an H-10 will pick up a leak of 1/4 oz. per year and should be able to find the leak. If it is in the lineset in the wall then go to the general contractor and let him know that he needs to fix under warranty period. They normally find a way to absorb the cost.
If the leak is in the wall it may require that the lines be disconnected from the units isolated and pressureized to test over 10 hours to 24 hours. But I have repaired lots of them and the first couple I will take care of but if they seem to keep happening with the same contractor then I start charging the gen. contractor.

Wish you well in your new home.

I Told Them To Find And Fix The Leak. I Will Follow Up When We Find Out What It Was.

I Had A Leak At The Service Port. I Was Not Charged A Dime And The Company Extended My Warranty Another Six Months. My House Does Feel Cool Now. I Have Kept A Eye On The Humidity, It Goes Anywhere From 47% To 53%. I Have Read Other Post That Say The Unit Has To Run Long Enough To Get The Humidity Down. How Long Should A Unit Run And How Often Should It Come On? I Was Assured By My A/c Person That The Five Ton Was Needed For My Home, But I Would Feel Beter If The Humidity Was Aroung 40-45%.

The Outside Temp Has Not Been Hot Enough For My Unit To Run Alot. With The Ac Not Running The Inside Temp Was 72. The Problem Is The Humidity Level Is 55%. Is This A Dangerous Level For Mold?
