Picture of the problem?

Is it going through a pressure switch before the contactor?

That motor looks pretty rough,probably not turning very fast. I'd buy a cheap $20 50cfm exhaust fan at nearest box store. Pull the motor and mounting plate out and install it back in yours,should go right in there with no changes.

Is it wired to the right side of contactor?

Have somebody check the heat exchanger that knows what they're doing.

That's part of it,there's also linesets and electrical work to be done.

Has anybody checked the flame sensor?

Tell that hack to redo that mess its sitting on,how about a picture of the rest of the install?

It will gain a little efficiency with combustion air brought in from outside,but will work either way as long as it has enough combustion air. What is his reason for issues with 2nd pipe?

It looks like 3 1/2t by the numbers on it,I'd like to see model number off of outside condensing unit also to be sure though.

That bump is usually caused by the pipe rotting from inside out.

I'd screw it on to an outside faucet and open the valve to see what you have for pressure. Anything much over 70psi will cause problems with pop off valves on water heaters,and fluid masters on toilets.

Check those roto loc fittings on the outside unit,shrader valves are also a common leaking point.

Do you have the model number off of outside unit so we can make sure of size coil you need? Biggest thing is to get a coil sized for the tonnage of outside unit,and to match the width of existing coil so it will fit existing plenum. Make sure your new coil is a 410a coil so you can reuse it if...

Looks like there's a rock between the pad and condensing unit in your picture.
