A/C coolant requirements, replacing both units

We need to replace our inside Trane air handler due to the coil having a leak. (installed 2001) When giving us an estimate for a new unit we were told that due to new gov't coolant regulations that if our outside a/c unit (Carrier heat pump installed 2003) should fail in a year or more we would again have to replace this inside unit again because the new outside unit not be compatible it.. They are recommending we replace both at this time or at least within the year. I would like to verify that this info is correct. Also, this service company has many great reviews, but only sells Trane. Any comments on Trane or recommendations on other systems we should look at first. We don't have a lot of time to look because it is already hot here in TX and we are without a/c. Thank you.

    Thank you very much. That helped a lot. I have since gotten an estimate on Carrier and we are seriously considering it.

That is true, what the company told you, due to the gov't upping the minimum S.E.E.R rating (Seasonal Energy Efficiency Ratio) it is heavily recommended by everyone in this field to replace both. It is a lot of money in this economy to do this but your energy savings in time will pay for it, I'm a Carrier kind of guy personally and with the new tax credits the government is giving for energy saving the Carrier Infinity which is the Cadillac of A/C units, is very cheap. Plus from experience it has saved my customers up to 65% on their electric bills

Yes and no. The government isn't requiring you to replace the unit with a more efficient unit. They requiring that A/C manufactures produce units at least 13 seer or above so A/C installers will not be able to get a unit to match your old units after all stock is sold about. This will happen in the next year or so. If you try and replace your old inside or outside unit with a newer 13 seer they are not compatible and it will not work very good. It may even burn the old or new unit out and cost you even more $$$$$$$ in the long run. The one you have now is probably about 10 or 12 seer since it was installed in 2001. The old equipment is still available to match yours, you just need to find somebody that is able to get it for you before all old equipment is sold out. Some of the large cities like Dallas Fort Worth areas of Texas are almost sold out of older equipment that is needed to match yours. But the equipment is still around if you check smaller populated areas or check Ebay for a 10 or 12 seer unit to match yours. Some A/C companies will not install the older equipment at all even if it's available. You are better going with a new inside and outside unit 13 seer or above to be safe. Also R-22 refrigerent will be phased out soon so you need to go with a system that uses R-410A to be even safer. Even if the new unit is 13 seer make sure it uses 410A refrigerent. They are still making the newer 13 seer and above units using R-22 refrigerent. 410A should be around for another 100 years or more. Trane is good equipment. So is Carrier, Reem, and Ruud equipment. If you take an A/C unit apart you will find they are all made of just about the same exact parts from the same manufacturer (and Made in Mexico) so don't be fooled into spending $1,000 more on a unit just because of the name but only if it's more effeicient. By buying a unit 13 or higher (14,15,16,17,18) you are sure to save on your electric bill compared to the older units before 2006. Another thing to take into consideration is that the larger copper tubing that connects your outside unit to the inside needs to be larger (at least 1 inch) or you will not get the energy savings on the newer units. So you will need to change the larger copper tubing out if it's not bigger then 1. The smaller tubing needs to be at least 3/8". Hope this helps.

Brand New 2 weeks old 4 ton Trane compressor leaks a lot of water onto pad

If the unit is running in cold weather than there is ice building up on the coils located outside. This is normal in that the unit is running in heat pump mode heating inside and cooling outside, After the unit detects the ice build up it briefly reverses the cycle heating the outside coils melting(defrosting) the ice which you observe as water on the pad.

The video gives you an example of the defrost cycle!

How do I fix my Trane air handler to keep it from turning off about 20 seconds after being commanded to turn on?

Some units require both a start and a run capacitor. It's possible the wrong capacitor was replaced. It's also possible to add a run capacitor to a system to keep the fan running. There is an outside chance the bearings in the fan motor are worn to the point it's time to replace the motor.

3 ton condensor and 2.5 air handler

I hate to use rules of thumb but 500sqft per ton depending on your windows and insulation. you are probably ok with a 2.5 ton however it will not work with a 3 ton outdoor unit as you have figured out. depending on how long that ac has been in you may want to replace it with a 2.5 ton due to the damage to the compressor valves because of the mis match. or if the indoor is newer and the original system may have been a 3 ton then i would replace the A/H. and be prepared to replace the outdoor if the valves are to far gone. If the trane is a new high effiency 2 and the goodman is just a 10 SEER you may be able to have a txv installed on the trane unit and a kickstart device outside. but only if its a high effiency but their again if the A/C fails you couldnt have a high effiency 3 ton you would have to drop down to 2.5,

2002 TRANE XE 1000 AC - small leak

that is no longer considered a small leak. having to add freon every 5 years is a small leak. you have a massive leak and it needs to be repaired or replaced imediately. you could be charged for freon release by the epa. check the coils and every joint and valve for oil drops or seepage or actual air leaks. for something that bad, you could use soapy water (dish soap) on the joints. where it bubbles is your leak. do not use soapy water on the evaporator (cold) coil. regardless, you need it repaired or replaced and it turned off until you can do so. it's either pay the epa $32,500, or get a new ac.

Need a replacement coil for a Coleman Evcon air handler Model # AH12L10NA. I am losing freon at a rapid pace. Leak detector indicated leaks in the indoor coil in the air handler. PLEASE HELP! Thanks in...

This may be a bigger issue than you want to tackle alone, generally speaking the coil will have to be ordered from a dealer, as most wholesalers will not sell to the general public. Further, this will require brazing the new coil in, evacuating the system, installing a dryer and recharging.

Trane air handler cycling rapidly

Depending on the age of your Trane unit. The fan relay has a time delay. This is a solid state board on the relay. Most of the time they stick on or off. Check for loose wires. But start with relay.

Inside unit freezing

There are varius items that make the unit inside (air handler) freezes up .If the fan motor in the air handler doesn't work it'llice up.If the filter is dirty it'llfreezes up. If the coil in the air handler is dirty it will freezes up.And if the unit is low in refrigerant(freon) it'll ice up.If is low in gas means there's a leak and before recharged it needs to be fixed.

Central Air, its a Trane, cools, however not very well. I think it needs a charge

First I would check your filters inside the furnace or air handler. Then if you have access I would check the a-coil. Sounds to me like you have a problem in the area of where the system transfers heat from the inside to the outside. Another thing that would'nt hurt would be to clean your condensing unit outside.
