Hi! I am a young homeowner (about 2 years now) and when my wife and I were getting the general inspection it was noted that our AC used R-22 refrigerant and might need to be replaced if it started leaking. After hearing how much it would cost to replace a system (and having some ideas of my own for improving IAQ) I have started down the road of getting prepared for a DIY replacement should that happen in the near future. From reading a few posts it sounds like getting the universal EPA 608 is a good first step. Are there any recommendations for online training courses that teach the material well? A quick search showed SkillCat but I am curious if anyone had any preferences. Thanks!

Looking forward to the channel to learn and share ideas

is this a legit seller of refrigerant? https://www.crefri.com/products/r22-refrigerants?variant=48332873007359 or https://ontapcold.com others? thanks!

Looking for help troubleshooting a New Cooper and Hunter 12k R410a mini split freon pressures are good but only getting slightly cool air 60* out of the unit. any ideas?

Hello everyone, I'm curious what kind of quotes you guys have gotten for a new hvac system? Im in a smaller town in Wyoming and i recently got a quote for 18,000 to replace my gas furnace and air condition with what seems like a pretty basic system. I really cant afford to spend that much. I feel like I can tackle this myself so I just wanted to get some advice. I appreciate this guys channel and it has helped me to keep my system going the past several years, but its looking like its time to replace! Any input would be much appreciated. Thanks!
