What is the labor cost to replace an A/C evaporator coil?

Question

My Carrier Puron system is only 5 years old, but appears to have sprung a leak in the evaporator coil (at least that's what the tech is telling me). Even though it's 3 weeks past the warranty, I got Carrier to give me a new coil. However, the HVAC company said it would cost about $850 in labor to pull out the old unit, drain the system, install the new coil and recharge the system with Puron. Does this sound reasonable?

Here's more background in case it matters: The system has been working perfectly for 5 years until a few days ago. Last week I was out of town and cranked the thermostat up to 85. When I came back I put it back down to 74. The system ran fine for 3 days and then froze up. I checked the filter and it was pretty bad. I replaced the filter and left the system off overnight to melt the ice. The next day it seemed to work OK for a few hours, but froze up again. I'm told that if the air flow is good, the only other reason for a frozen indoor coil is low refrigerant. And in a closed system, the only reason why it would be low is if you have a leak.

I haven't had it replaced yet, and when they looked at it today they added some refrigerant. Now it's working fine, so I'm wondering if I should replace the coil at all. But I suspect that it will eventually leak out again, so it's probably a good idea to replace the coil while I can get the part for free.

Answer 1

sounds reasonable on a central unit, the tech will have to reclaim the refrigerant, and that costs money, thank you EPA! his time, the acetalyne gas, sauder, new refrigerant, all costs major bucks, be lucky you dont have to buy the evaporator, then your looking at thousands, get it done sooner then not, what will happen the hole WILL get bigger, moisture WILL get in the system, and then say good bye to the compressor, and that is NOT cheap. asap is an expression i do NOT use lightly, easy way to put it, your docter tells you that you need open heart surgery, would you put it off? the compressor (the heart of a refrigeration unit) WILL fail.

I was told today that my Amana split system has some rust in the evaporator coil, $155 to clean but it may cause more problems. The system was installed 10 years ago last December. The tech showed me the Heater portion of the Amana is now 18 years old. The contractor installed an eight year old system that looked new out of the box. He said it would be around 3K to replace the evaporator coil.

$850 sounds a little high. I would maybe get another opinion. I know that's a pain but did the guy actually hunt for and find a leak on the coil? Is he sure it's the coil? Did he do a leak check on all the joints? A lot of time the valve cores where you put your hoses on leak a little but you don't find the leak because your gauges are on the machine.

You can do a leak check yourself by using thick soap bubbles and soaping up every joint. You can take the evaporator coil door off and check the coil for yourself.

Make sure you didn't cover the return grill or anything else that might lower air flow.

Answer 7

The next time it leaks down have them pressurize the system and spray soapy water until they find the leak. I have never heard of a coil going bad in 5 years. They should be able to solder any little minor leak without replacing entire coil. They would have to prove to me that was where it was coming from before I replaced the coil.

Answer 8

I would have to agree with everything you've said. Even the price. Leaks are common on evaporator coils after a freeze.

Get a second opinion and do not say anything about the evap. leak, it maybe be leaking some place else.

Answer 10

$400 labor, plus refrigerant on a per pound basis....410a = $40 per pound.....R22, eh, put a new system in, you will be money ahead!
