A/C not cooling well.

Here in North Texas the heat has finally arrived and issues that might not been noticed are now starting to show up.
OK so here is what I am seeing on my unit.
The other day I noticed that both levels were not reaching the desired temperature.
The air coming from the vents was cool but not flowing that well.
I mowed yesterday and the condenser looks fine, rusty but fine. The grate seem clean and I don't see any condensation around the condenser.
When I was mowing I did see a pretty significate amount of water around the overflow pipe outside.
I changed the air filter in the air handler. It probably had been about 2-3 months since it was changed and was looking pretty bad.
I see two PVC pipes coming out of the air handler and the one on the right (the overflow) one has some condensation on the pipe. There is no cap on the one on the left PVC pipe so i don't see a way to get to it to clean it. I also don't know where it drains. I have been trying to track it down so I can maybe pull the line and clean it out. Any idea where it might terminate?

Do you have a condensate pump?

I don't believe so. I don't see any pump there.

Sounds like it's draining out side? Is your furnace in the attic?

Ok.... so that's where the condensate is draining to.

Too many times the entire system is not performing near to it's nominal Rating; a total check on performance may be in order.

You could collect some temp & humidity data so we could make some assumptions concerning performance...

Performance Data Collection – Best Time to collect data is late afternoon around +4:30 pm, when attic is HOT; also when outdoor temps are around 85°F to 95°F.

*All U need is a good air-temp probe thermometer (digital reading in tenths preferable) and a low cost 'Indoor Humidity Gauge' > ACU-RITE Digital only $8.94 at Walmart or over the Internet.
This form is for anyone to use & come on here to have us analyze if U need to call an HVAC Contractor.

1) Helpful: condenser 'Tonnage' & SEER Rating of Unit &/or model number:
FIRST; We need to know the 'Indoor' % of Relative Humidity______ %

2) TXV or, orifice metering device? _______. Only if U know; not critical…

3) Outdoor condenser’s discharge-air-temperature ___°F

Subtract Outdoor air temperature: _____°F

Outdoor Condenser Air-Temp-Split ___°F

4) Need the ‘Indoor’ percent of relative humidity - in the middle of the rooms or, at Return-Air inlet grilles ___

5) Indoor Return-Air Temperature ___ °F

Return Air Temp ____°F Subtract Indoor Supply-Air Temperature ___°F
Indoor temperature-split = ___°F

I have climaconvectors from Verano. Had to change all my heating system in the living room (get rid of radiators) but it was worth it. They are even better than AC
