DIY- Replacing a Mini Split
I had a Lennox mini split stop cooling/heating so I called out a AC technician that informed me the that pretty much there was no refrigerate in the 6 year old unit so he suspected there was a leak. Had my recharge the unit after using some leak sealant but after a week of use its back to not cooling again so I was looking to replace the indoor unit since I believe that's where the leak is (I'm strictly guessing this only because the fins in the unit have been cleaned a few times). Issue is its a Lennox high wall heat pump indoor unit (model says MWMB009S4-1L) but the only parts I can find are the wireless remote and cover. I'm wondering what my option are before I hire someone to purchase a new mini split/AC lines and have it installed which is going to be quite expensive (really the labor of running the new lines in the walls of a 4-story house, and units) Replace the inside head unit with a similar unit (if I can find one) based on the model # which tells me the type, cooling, voltage, etc. A gamble since the AC lines or outdoor condenser unit could be the culprit Replace the entire system with another Lennox or another brand (minus the AC lines). System could be pre-charged vs charging myself, vs having some charge it https://preview.redd.it/9tqq3p5avjse1.png?width=738&format=png&auto=webp&s=56c68fb21f2dea49753a4f64ba957499898ce837 https://preview.redd.it/y3xkle2fvjse1.png?width=287&format=png&auto=webp&s=68ab2d36adaf3100210bef08f5be45b453e2f191 submitted by /u/FlexFanatic [link] [comments]
