AC maintenance
« on: April 25, 2012, 01:30:14 PM »
I want to do my own. It's totally unmustacian to pay for that right?

Here's the deal, it's almost impossible to find a good DIY guide on the web, it's overrun with "call a professional." Anybody have a good link?

On the same topic... how often should you do "maintenance" on your home A/C?

Search Google for "diy air conditioner maintenance -professional". Search Youtube. If you run into a specific problem, ask on a do-it-yourself forum, like this one:

Mr. Lilac is a furnace/AC guy for a living. He said you can clean the outside unit yourself, but shut off the power first and "don't beat up the unit", for example using too high of a pressure of water and bending the fins. Things like checking the level of the coolant is, in our area, only to be done by someone with a licence. The gauges are somewhat expensive, you need to know what you are looking for, and most importantly, if you do it wrong, you could release harmful gases into the environment. He said it is also hard for the layperson to check the electrical.

Best thing you can do is make sure to change your filter every month. (We have a washable filter.) If you don't, it makes the furnace work harder and can cause the motor to burn out. He also said the really fine filters aren't worth it, but to buy the accordian type filters because those fibrous ones don't keep enough crap out of the furnace. (he recommends the red Filtrite or similar.)

Basic maintenance is the best thing you can do in his opinion!

I'm all for Environmental Protection, but it bums me out when you can't learn to do things on your own. The link to the DIY forum above is one I visited before where I was noticing a lack of info. Looks like it more because of legal requirements than lack of information. See the link below. Any posts about charging your own AC will be deleted.

I hope no one ever takes my soldering iron away, or requires me to get a license because it contains lead.

It looks like the certification just involves a test. If the system you want to work on has 5 lbs or less of refrigerant, only the first of three certification levels is required.

That is shocking. My husband had to do a four year apprenticeship to become a journeyman. He said most residential units are under five pounds, but newer ones are are starting to be more.
