Last month, I was dealt a frustrating blow as my apartment’s window A/C unit broke down on me again. This was the third time this year, and at this rate the window air conditioning unit wasn’t going to last into the summer! When my landlord called saying that he could replace it for me, I asked him to consider another alternative first. Let me just explain something here: In hotels, each room has a singular A/C unit, but it isn’t mounted into the window. These “room air conditioners” are useful as they provide a level of heating and air conditioning that is perfect for that room. Well, ductless mini-split A/C systems are very similar! With those, the outdoor air condenser and compressor takes outside air and chills or heats it. Then, the air is transferred indoors and dispersed through an air handler that has a built-in thermostat. Now then, I thought I could convince my landlord that I could install the new ductless mini-split A/C system on my own in my apartment, if he were willing to buy the system. Seeing an opportunity to avoid hiring an HVAC professional to do the job, he took me up on the offer and bought the ductless mini-split system for my unit! I was pretty surprised, but still determined to install the system myself – even if I didn’t know the first thing about installing a ductless mini-split HVAC system. I managed to get the outdoor air compressor and condenser into place, and then I was able to get the indoor air handler and thermostat placed on the wall. The only hangup was when I realized that all of the connections for these two pieces of equipment had to go through the wall, and I had no way to drill a big enough hole! I wound up hiring a HVAC professional to help me install the system.
