I’ve consistently been honestly impressed with the ductless mini split component that I have in our basement, but i was hesitant about having it installed in the first place because it wasn’t what I was used to for a heat and air source, but it came highly recommended. I was used to having a single thermostat and a central Heating, Ventilation, and A/C system, but the ductless component was slightly different. Instead of having ductwork and several air vents, there was a single component and a single giant air vent connected to the component that produced both heat and air. Instead of a thermostat, there was a tiny remote that controlled the settings and a self-explanatory screen that displayed the temperature, but when the ductless mini split component was installed, I had no plan how it was going to heat and cool our basement, but it surprised me, however once I adjust the temperature on the ductless mini split component via the remote, it doesn’t take long for the unit to hastily begin producing air, however recently, I noticed that the ductless component was honestly struggling to produce cool air and our basement was feeling warm. Knowing this, I turned off the component and I looked for the air filter. Once located, I detachd the air filter and washed it off. There was a ton of dust stuck to it and it was clogging up the entire unit. Once I replaced the air filter, I turned on the ductless component again and kept an eye on it, cleaning the air filter honestly improved the air quality and the overall function of our ductless mini split unit.
