Where can you buy air conditioning equipment online?

I found a company called askarepairtech.com. You can buy a new a/c unit or furnace from them at contractor pricing. They also sell parts for both. I called because my furnace wasn't working and I spoke to a technician on the phone for 20 bucks and he was able to diagnose the problem. I purchased the part through them and they shipped it to my door. It took me about a half hour to install the part and I saved myself probably $200.00.

Also you can research eBay and some popular classifieds sites. Congratulations for saving 200 bucks!

Try to visit eBay, Amazon or some online classified ads.
