Not an expert but you may want to check out your compressor.

Mine took a dump earlier this year and I replaced the whole condenser unit.

Also, I installed a small 110v window unit years ago that I can use for "emergencies". When an AC issue comes up with my central air....it buys me some time to figure out a game plan or do diagnostics.

There's a lot of info on You Tube plus some really great folks here who know their stuff and can help.

Good luck!
