Angry A/C mods or better cooling tips ???????

2010 Honda Insight

Hi its 116*F today and im melting the A/C in this car is real junk. When i reach a stop the A/C cooling is sooo weak but when i get up back to driving it starts cooling fair to okay.


I added freon and overfilled it to the point where the AC wouldn't turn on and then i had to let some out.....shhh and brought the pressure back to where i started I saw some cool idea of someone using a pool noodle to cover the low return line to help but i bet that's a stupid idea as it would melt and cause a fire. My radiator seems fine the coolant looks fairly clean and is between low and high. so what gives!!!!!!!???? my only guess is the fans are weak and when at a stop they cant keep up but when driving the help of the wind cools..



so my question is...... what else can i do for cold air???

> new cabin filter in (done)
> windows are tintied (done)
> new freon added......then removed :/ (done)
>maybe a type of heat resistant piple foam? (will try)

Good Day. I just purchased my 2010 Insight last fall and have encountered similar issues. Tried topping up coolant but it was fine. Switched off ECON mode when stuck in bumper to bumper traffic. At best I would get 10-15 minutes of cool air but would gradually fade out to blasting furnace hot air if I left the fans on. Was looking at the AC relay and picked up a 39794-SDA-A05 relay from the dealership... but Im not sure now if thats the right one. Beyond swapping out the relay, (or jumpering it to kepp it always on) Im not sure theres much else can be done. Sorry for the hijack but can someone confirm if this part above is correct for the AC relay? Thanks a bunch for any help.

Default Set at lowest temperature

Turn the temperature setting as low as it will go to avoid the "reheat" feature of your A/C system. If you get too cold, you can always shut it off until you warm up.

You may get icing up in which case you will not get any cooling. You will have to wait for the coil to thaw out before cooling can resume.

What is the temp reading on the air outlet on the dash?
If you have around 55 F that is about the lowest you will get.

I typed out some advise on this this morning, but it seems to have disappeared.

Anyway, the first thing is to go beyond just turning off ECO, which helps a little, to just driving, in traffic, in S instead of D. This will keep the engine, and the A/C compressor running. This car does not have electric cooling like some hybrids. No engine, no cool. When it’s hot, I don’t give a rats about fuel economy.

The other thing is to actually not set it on low, but to select a very cold setting, it just seems to cool better. This has been discussed around here before. My wife, the primary Insight driver in our household, collaborates this. And believe me, she wants it as cold as possible. The A/C has never been off in 130,000 miles.

(Some folks will take offense because the directions on a cake mix box do not say "please".)

No offense implied, if the temperature setting is on the low extreme, the compressor will not shut down and will run constantly unless YOU switch it off.

thanks for the input but its way to common, guys or girls i need advance tips. Like im not even talking about settings ive maxed out those of cooling. Now im thinking of using flameproof pipe insulation to cover the entire A/C low line.
