+# Cooling My Garage with a Mini-Split
+
+The best place to build my homelab is in my detached garage. The problem is that there is no AC and the temps are way too hot in the summer.
+
+My solution: install a mini-split air conditioner. This proved to be a challenging project but I'm happy with how it turned out.
+
+I won't go into detail about the install process (there are tons of great tutorials on youtube).

+
+This unit required a 220v disconnect, so I had to replace the garage's subpanel with a larger box to accomodate more breakers. Then I ran a wire from a 220v breaker to an AC disconnect which I installed on the outside.
+
+These units are pre-charged with coolant so once I connected the high and low pressure lines I released the coolant and had cold air!
+
+One issue: I learned the hard way that the PCBs in these units are sensitive to power surges. We had a thunderstorm which fried the PCB.

+
+Fortunately the company sent me a replacement PCB. Once I swapped it out it started right up. To protect the PCB from future surges I also installed this surge protector to the disconnect.
