SOURCE: Air condition jsut 10 month old ... not keeping up whith cooling

If it's only 92° outside and the unit won't cool the house, then the unit is either to small or it's low on refrigerant. They are designed to cool a house with outdoor temperatures up to 115° to 120°.Usually you need one ton a/c for every 400 square feet of house, but, you have to take into account for average outdoor temperature and humidity, windows, doors, especially sliding glass or patio doors and which side of the house they are on, insulation in walls and attic.
The air leaving your duct work going into the rooms should be about 20° lower than the room temperature, if you have a 80° room then the air leaving the duct should be around 60°. if it is then the unit is probably to small if, everything is working properly.

SOURCE: We have a goodman air

I am assuming from your problem description that the unit is cooling some but not as good as normal. If that is the case then the system has lost some of its refrigerant charge.
Recharging the system will correct the problem but only temporarily.
The system has a refrigerant leak that must be found and corrected for a complete repair.
Be sure to get a reputible( ask other people for a reference based on integrity and skill) heating and air contractor/technician. I would suggest staying away from big companies as their technicians are poorly trained.

If they say you have a refrigerant leak , have them show you exactly where it is and have them squirt bubble solution on the leak so you can see it.

If your system is only 3 years old then any major parts are under warranty. This does not cover labor.

Hope this helps.

SOURCE: drain inside house from a c is over flowing.central air


I am a certified HVAC Technician. I have worked in the field since 1996. I have seen this hundreds of times, if not a thousand times, in the past. Every central air conditioning and heat pump system comes with TWO drain pans, The MAIN drain pan is located within the AIR HANDLER (blower) UNIT, while the EMERGENCY DRAIN PAN is extremely LARGE and sits under the ENTIRE AIR HANDLER (blower) UNIT. The ONLY time water will be INSIDE an EMERGENCY DRAIN PAN is when the MAIN DRAIN PAN condensate drain line is CLOGGED, causing the MAIN DRAIN PAN to overflow. What causes the drains pans OR the drain lines to become clogged is slime and scale from the condensate water as well as debris from within the attic that may have either been blown by the air or may have simply have fallen into the emergency drain pan; or some insects from the out of doors have traveled up into the PVC Drain line and built a nest on the downward side of the P-trap. The P-trap is designed to prevent critters from entering your home through the PVC drain lines. Most CLOGS occur at the P-TRAP location.

The BEST thing to do is:


1. Locate the WHITE PVC drain pipe outside your house and ensure there is NO water draining from it.

2. Locate the same WHITE PVC drain pipe inside your house. You should notice a "TEE" where two WHITE PVC drain pipes merge into ONE WHITE PVC drain pipe.


Follow the below steps, in the order shown:


A. FIRST, find another person to act as your second set of eyes at the end of the WHITE PVC Drain Line that is located outside of your home. That person will be looking for water or debris to EXIT the end of that WHITE PVC DRAIN LINE.


B. SECONDLY, locate the WHITE PVC "P-TRAP" inside your house. It is normally located within a couple to three feet of your indoor air handing (blower) unit.

C. THIRDLY, very gently lift the entire WHITE PVC drain line up in the air as high as you can without breaking it, and slam it down onto the rafters or attic floor or garage floor. You are attempting to dislodge the CLOG within the drain pipe WITHOUT having to actually CUT the PVC and without damaging or breaking the WHITE PVC. Depending on how old the system is, it may or may not be brittle; and it may not take much to damage or break the PVC, which will cause leaks. So, be very careful at this point.


D. Ask the person outside if anything has started to EXIT. You can ALSO usually hear water start to drain if you put your ear up to the drain line. If the person said "NO"and if you don't see the water level getting LOWER in the EMERGENCY drain pan, then REPEAT step "C" above.

E. If the person informs you that there IS water now starting to exit the WHITE PVC DRAIN PIPE, you should then wait until all water has drained from the EMERGENCY DRAIN PAN; and then pour at least 1 quart of BLEACH down that drain, from the EMERGENCY DRAIN PAN exit. The BLEACH will further clear out any SLIME which may be remaining within the "P-TRAP" and will also CLEAN OUT and DISINFECT that drain line.

If the above steps do NOT work for you, then prepare to go into the next LOGICAL phase of your attack. Please NOTE: I am limited to 10,000 characters in my response, so I'll repost additional STEPS in another RESPONSE. Good Luck!!!

With a typical line set, how much R-22 should a ckl30-1 2.5 ton a/c need?


the refrigeranterant charge is stamped on the unit data plate in ounces of freon. take this number and multiply it by 16 and get the pounds and the decimal point will need to be converted back to ounces. example 138 ounces equals 8.625 lbs of freon which is about 8 lbs and 8 0r 9 ounces. this is for a 15 foot lineset. measure your lineset and substract 15 , then take this number and add .6 per foot. .6 ounces of freon per foot of refrigerant line over 15 feet. you will have to use a quality digital scale to weigh in this total charge

My A/C blowing air, but it is not cool. It has started freezing up. We just replaced the air filters and since then it is freezing up. We even gently cleaned the a/c coils before replacing the filters. ...


Hello, sounds like it is either a low charge or lack of airflow, what type of filter are you using? sometimes those filters that claim to be super effecient will actually cut down on your airflow and cause the ac to freeze up.

Outside unit runs, air handler inside runs sometimes Is there a fan relay that will work sometime? can here freon circulating but fan will not run. Can cut off and restart, will come on sometime. ...


Their is a fan relay on combo gas heat and central air conditioning.
The reason is for heat you need slower fan speed than for air. How do they do it? They use a relay to shift the fan from low for to high for ac.

My heat unit will not blow hot air unless we go outside and hit a button on the back bottom of the unit. Once we do that it will blow hot air for that cycle. when it is time for it to come on it is cold...


If it does not have a furnace or heating elements for heating, then it is a heat pump, which is rare for a central AC system, but makes sense of the fact that it blows warm air when you reset the pressure switch, which may indicates freon pressure charge problem if your AC system has a reverse valve and uses freon to for heating (heat Pump).

Do you get heating when outside unit runs? if you do, check freon pressure levels and top up to required pressures. The button you depress is a pressure reset switch ... that is if your AC system is a heat pump ... which, as pointed above, it is not common for central ACs.

Air conditioning unit


On a "Non Heat Pump" unit, icing of the pipes is not good. It is an indication that you either have a low freon level (Charge), low load, wrong superheat.
A low load usually means, in this case, something wrong with the air flow. Clogged filter, wrong fan speed, something blocking the return air grill, like a chair/ blanket, etc.
If low on charge, the evap (Indoor Coil) will ice up and the ice will then slowly creep along the pipe untill it gets to the outdoor unit. This is really no good. Air cannot go thru solid ice so naturally there is no cooling happening.
If a company replaces the outdoor unit (Condensing Unit), there is no warranty on the indoor unit. I do not know of any company that will repair an indoor coil (Evap). Just not smart money. They have to capture the freon, open the system, make the repair, ensure the correct level of freon is in the system, and most time, add a filter/ dryer for additional filtering and drying of the freon. With all that, no one is going to patch a leak on an old coil because if it leaks now, it's going to have another soon. You'll just be chasing leaks and spend money after money. Hope that makes sense. HVAC companys have to follow the EPA rules too. Leaving a system leaking above a certain percent of it's total charge is a major no-no. They will not do it.
Hope this helps clear up a few things and good luck.
