House - A/C Not Strong Enough?

It could be a lot of things.

Clean your vents? Check your vent filter? Get a new AC unit?

Check attic insulation, vents, clogged filter, etc.

I had this exact problem.

Go outside to your AC unit. Is it blowing hot air out of the big vent at the top? If not, your AC may be leaking refrigerant.

Call a AC technician to have it patched and refilled. I paid $250 to refill my 1.5 ton unit, it's really cold now.

Keep in mind that hot air rises, so the upper floors will almost always be slightly warmer than the downstairs.

Just bought a 1 yr old detached house and noticed that the A/C doesnt seem strong enough on the upper floor. What should I do in this scenario? Would appreciate if someone could point me in the right direction...not even sure what to look for.

Thanks guys!

Measure your air temps just before and after your HVAC to see what temp drop your getting.
Close vents in the lower floors and open them in the top.
Close dampers to the lower floors and open ones to the upper.
Check filter and replace if dirty.
Make sure your AC outside it not dirty or obstructed.

Thanks for the advice! Where is this filter located? Inside the AC unit? What is a damper? Sorry for the noob questions first time house owner.

The filter is in your house, just before the HVAC blower. It should be labelled and behind a slot cover.
