air conditioner question Sign In

When I drove my 2013 Hyundai Accent yesterday, the air was cooling quite well. Then it started blowing out only tepid air. I drove for a few more minuets more and the good cool air started working again for the rest of the way home. What do you think is up with this?Frown
Thanks!

Guess who's up? Hi Janet, A/C in high need is working hard already, lots of places brings out the issues.
Those symptoms could be a few things will take some observations. First for you and anyone pay attention to fluid levels and temp gauge of your car.
So of a few see if you can hear or see fan for engine/A/C condenser is working hard if you have to pull over when it does this. That's also a time to see the larger A/C plumbing sweating or if frosting up, I'd like you to witness it as it may not do it when or if it needs help later.
Same time look for dripping water under car - the normal dripping A/C does don't confuse that with some fluid leaking. If humid there should be lots.
If none, try this:
Shut the system off or whole car and watch for a large puddle indicates ice is melting unseen inside dash parts called the evaporator. You need to catch it when it warmed up after full A/C request isn't working so well. I could also feel like less air is blowing out panel vents.
Chances are when A/C isn't performing there's a leak of refrigerant (more than 1/2 of issues are that) to be found and fixed. Easy problem or normal for many to be elusive but caught low would then have a shop just evacuate system and charge up again to specific amount is not DIY practical.
Your observations could help solve this, those are what I'm thinking for it right now,
