Definitely look at the expansion valve and the accumulator. If there’s a blockage, pressure readings can be misleading. Also, check the hoses for any kinks.
That makes sense! What if it’s not a blockage? Could it be a compressor issue?
If the compressor is failing, it might not be drawing enough refrigerant, leading to high low-side pressure. Listen for any unusual noises or vibrations at the compressor.
I’ll definitely listen for that. But what if it’s just a refrigerant leak?
A leak will usually cause low pressure rather than high. However, if the refrigerant is incorrectly charged, it can lead to unusual readings. Have you checked for leaks using a UV dye or soap solution?

Just a reminder, don’t forget to check the condition of your AC filters. A clogged filter can alter pressure readings and affect performance considerably.
Good point! I hadn’t considered that. How often should I change those filters?
Ideally, you should check and replace your filters every 1-3 months, especially during heavy use. It really helps keep pressure readings stable.
This all sounds so complicated! What if I just take it to a mechanic? Is it even worth trying to diagnose it myself?
It could be worth trying just to save some money. Diagnosing can give you a better idea before heading to a mechanic.
Unless you’re really stuck, it’ll save you $$$! But make sure you have the right tools and take safety precautions if you decide to check it yourself.
But if all else fails, don’t hesitate to seek professional help! Sometimes, a fresh set of eyes can catch things we’ve overlooked.
Let’s face it, AC issues are like diet plans—hard to stick with on your own! Advice from a pro can definitely simplify things.
Haha, that’s one way to look at it! But seriously, I’m leaning towards the idea of calling a mechanic soon.
AC low side pressure at 150 PSI can indicate several issues. First, check for refrigerant leaks, as they can lead to low pressure on the low side. Use a UV dye to help spot leaks. If low refrigerant is confirmed, consider recharging with the appropriate type and amount.
Have you checked the pressure while the AC is both on and off? Sometimes, the readings can differ significantly depending on the state of the system.
I had a similar issue last summer! We ended up replacing the expansion valve, and that made a huge difference. Make sure to check that component if you’re still having trouble.
Replacing the expansion valve sounds like a solid plan! What specific symptoms led you to that solution?

Consistency is key with maintenance! Regularly check your refrigerant levels before summer hits, and consider servicing the system completely every couple of years to avoid low pressure surprises.

Totally agree! Maintenance can save so much trouble later. What do you think about DIY versus professional servicing?
