Remove A Coil For Better Air Flow?

Just had a new Trane 2 stage furnace installed. After checking air flow and temperatures before and after the A coil, the differenceís are quite radical. Tech says itís because of the older ďfatĒ design of the coil and itís basically blocking the heat / air flow. AC is working fine and I donít want to purchase a new unit right now. Iím thinking of removing the A coil during the heating season and putting it back in the spring without cutting the lines. Is there a problem Iím not seeing by doing this?

The line set (refrigeration pipes) are not meant to be bent once installed. You are likely to break and cause a leak.

Sometimes what is needed is to clean the coil.

If you gain access to the coil and remove a sidecover a flashlight can be directed to one side of the coil and what is between the coils can be seen from the other.
The other thing is that a competent tech should be able to measure the pressure drop of the coil and make adjustments to the airflow to match the coil you have.
"Older" coils should have no problem working properly with a new furnace!

Thanks to both of you! Not really concerned about breaking or kinking the lines since i have an abundance of line slack and a lot of swinging room... Iím going to remove it and suspend it during the heating season. It just seems reasonable to think the furnace / heat will run more efficiently with the coil not blocking flow.

Temperature measurements directly above the furnace are not accurate, the thermometer picks up radiant heat from heat exchanger.

Don't mess with it. No one removes a coil in the winter.
