for the cost of a coil you should replace the whole unit... An a coil costs me about 280 dollars and takes about 2 hours to correctly install and pull a vacume on...I can buy the whole airhandler...with heat pup and electric heat 10kw for 350 and can install it in about 2 and a half hours done correctly with a vacume and using duct mastic ...not foil tape....have a great day and good luck...Donald Unless it is a furnace, then there is no airhandler and the only option is a new coil.
The evap coil can be changed. However, depending on what kind of A/C unit you are talking about, it might make more sense to replace the whole unit. Also, before you invest in the time it takes to do the work of replacing the coil, make sure the rest of the unit is in good condition.
You can save some of it by: Close condenser valve to evap coil - Use guages to prevent exceeded max pressure. Run compressor to store gas in condenser. Cut off evap return line at compresser. Replace evap.
Absolutely not.
yes....just need to support evap coil and plenum while removing furnace and seal back up once furnace is set into place.
$400 to $900 depending on the evap size, location and access to the unit for the serviceman. A crawl space is not cheap or fun.
I have a 94 and mine was in the lower evaporator coil line actually in the coil at the firewall. It could also be in a fitting on the smaller line coming from your evap. coil.
I got an 06 and the evap can is a black box-shape located by the feul tank...easy to replace.
not very well. a 4 ton system needs about 1600 cfm to provide it's full capacity of cooling. a 3 ton furnace puts out about 1200 cfm. in addition, the evap coil typically attached to the furnace needs to match the tonnage of the outdoor unit. so, the evap coil must be 4 tons. If you currently have a 3 ton furnace and evap coil, the system will not work, and you will most likely ruin the compressor in the outdoor unit.
The coil is inside. Check to see if the filter is dirty as well. To clean the coil you must remove the front panel to the evap coil. If you have a flat coil you must slide the coil out to clean it. If you have an A coil, take off the plate on the front of the coil and you should be able to visually inspect the coil. It is important that you do not mash the dirt into the coil fins.
The evap itself is about $100.
It depends on what failed. Here is a list of possibilities. Bad vacuum switch, damaged EVAP line/canister, open in PCM circuit, open or short in voltage feed circuit to purge solenoid, faulty purge solenoid, restriction in EVAP solenoid, line or canister, corrosion in purge connector, or a bad PCM.
You can remove it and clean the filter inside it or you can replace it.
