I mentioned this here before......I installed a small window unit in my living room that I can run if my central system happens to go down. Thus buying me more time to do troubleshooting or arrange for a service tech to come out, in the event I'm unable to figure out the problem.

That's first and foremost......have a Plan B.

I also have another larger window unit I keep in it's original packaging that I can set up in another window in less than 1/2 hour if needed. Would depend on time of year the AC went down. But point is...give yourself options.

Both these window units run on 110v and just plug into a nearby outlet. Easy peasey.

As for capacitors......there are tons of videos on You Tube which explain how to test them yourself. It helps if you have a test meter that measures capacitance in micofareds.

One time I took my capacitor with me as I went to work and when I saw an AC service vehicle at a property, I waited until one of the techs came out and asked him to test my capacitor with his tester in exchange for a few bucks. He was happy to do so - it only takes a minute.

You can buy these capacitors online. EBay is one place I have used but there are others. I also bought from the local HVAC business who installed my system. They normally have them in stock but no way you should have to pay more than $20. You can buy for less online.

The important point is the first paragraph about positioning yourself so you are not in a time crunch and can explore various options which hopefully will result in savings as well as a more efficient resolution.
