If indeed your evaporator (indoor) coil is leaking, the best option IS replace it (it may not even BE repairable). If you live in the USA and your furnace is getting old, a new ultra high efficient SYSTEM that qualifies for the tax credit would probably be a better option (Obama will pay 30%).

Replacement for 20yr old A/C system

I you have a 2.5 ton condenser on a 3 ton coil, and he gave you an estimate for a 1.5 ton condenser only, he missed something, or you need a second estimate. Now if give you an estimate for a complete system, with a 1.5 ton condenser/evap, coil, your ductwork will/may be oversized for that unit. Need a second estimate. You've been happy with a 2.5 ton cooling capacity in the past, don't settle for anything less, unless you've completely updated with new doors, windows, insulation, ect.... I'd call around and ask for an estimate, with a load, and then ask for the cooling tonnage and furnace BTU's from that load, when they call with the price. Most reputable companies will/can prove a proper load calculation and my city just made it mandatory to prove a load was achieved when a permit is pulled due to the Dept. Of Energy passing laws on this subject in 2015. Ask if its mandatory for a load calc. if they pull a permit. And they are supposed to pull a permit in city limits I'm sure. It's not a good practice to miss match systems with current designs. 20+ years ago it was, but now there are codes against this practice. And also shortcuts to try to make more money with less invested may not be considered GOOD PRACTICE. Hope this helps!

Pa12NA048-d. How many tons is this unit? It's 7 years old and went out. Needs replacing.

Hi, the tonnage is a 4 ton unit. It says in the model number, the 048. There is 12,000 btu's per ton of cooling. So, on your unit 4x12=48= a 4 ton unit.
Good Luck,

I have a 5 year old Carrier 2 Ton hvac system and heard that the CK5B N Coil has been know to have issues. I had the system looked at a year ago and the coolant was low. They added coolant but never...

We have noticed some of these same problems in TEXAS.. the coils have a potential to leak earlier than their expected lifetime but the problem is not severe enough for government to force a recall unfortunately... Maybe in 10 years... grrr right ? .. That price is good for materials and labor to change the part under warranty and most system checks for service agreements do not include looking for a leak.. usually just cover a pound or two of refrigerant.. I hope this helps.. the new coils are awesome..

My LG 1 ton window AC is in running (as the sound of running compressure is there)but there is no cooling effect inside, nor any heat in the outside fins.The ac is only 2 years old. Is it due to leakage of...

Hi, if you can hear the compressor running and its blowing room temperature air only, yes, if the air from the out side condenser coil is not hot, I would say you are low or almost out of freon. This is something you will have to call a tech out to find the leak and recharge. Even though it is only 2 years old, they can get leaks due to vibration. I don't know what you paid for it, but it will cost some $$$$ to have someone come out. It may be cheaper to replace it, as the leak could be in one of the coils which it wouldn't be worth fixing. Let me know on what you decide and if you need my help.
PS Take a water hose and wash the out side coil off. do not bend the fins. See if it starts to cool then. If not, you are low on charge.

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.

Inside coil ices over

You have 3 ton unit. Reasons for icing are stopped up filter.dirty indoor coil and low on refigerant. The first two you can do but the last you need a service tech but ask for free estimate first. RUSS

Tube running from AC unit to the house is completely encased in ice. Does this mean the unit is bad ? Or, does this mean there is a freon leak in the tubing ? And, is it cheaper to replace to unit or try...

You either have a refrigerant leak or a dirty inside coil or a slow running inside blower motor.
Set the thermostat for heat and run it until all the ice is thawed. Then check the incoming air side of the coil for lint and dirt. Check the fan motor for proper speed. If you have service gauges your low side pressure should be approximately 68 psi. If lower you have a leak.

Odor coming from heater vents

Freon should not be leaking from unit at all. I would not pay for freon that has leaked out due to a poor installation. Maybe the technician who installed this unit needs to rethink his choice of jobs. I would contact the owner of this company who installed it and if you get no positive response then find a new a/c company. I have installed about 40-50 of these units and check each one of them for leaks prior to filling the system. Shame on them for not taking pride in their work. Good luck.

Replace old Carrier condenser

Don't even think about it. This is an industry where you get what you pay for most of the time. Is your system not working currently? If there is a guy willing to install a system you bought off the internet he doesn't belong in this industry. I have gone behind people like that and had to explain to a homeowner how someone did a complete botch on their job and I have to rip it all out and start over. BE VERY CAREFUL if you want to try that. A company's price is usually a reflection of their quality and level of service. When was the last time you ever got anything of the highest quality for the cheapest price?

Carrier indoor coil replacement

yup, entire system needs to be drained, and leak needs to be repaired first before charging with freon.

after sealing the leak and test it is ok, evacuate the system for about 30 mins before charging it.

you may need a qualified tech to do that because you can not buy freon now a days.

you need to weld the leak also. you will need portable torch to weld copper pipes.

you will need vacuum pump to evacuate the system before charging with freon 22.

tnx 4 using fixya,
