I installed ductless mini split system in our sunroom and I love it. It keeps our sunroom heated and cooled to the perfect temperature and it makes the space more usable. I didn’t want it to be another household that had a sunroom that sat untouched due to incapable heat and air. Since sunrooms let in a great deal of natural light, the space tends to be naturally warmer during the summer months. I keep the ductless mini split running most afternoons to keep our sunroom comfortable. I use the sunroom frequently since I’m at home a lot and it’s kept comfortable and ready for my use. It doesn’t take long for the ductless mini split plan to heat and cool the sunroom, but it’s nice to have it running. What I didn’t anticipate was that a ductless mini split plan would need maintenance. When the Heating and A/C professional was at our home in order to maintain our Heating and A/C plan before the winter, she looked at the ductless mini split system and told me that he’d take a look at it. I watched as she took some pieces off and pulled out a dirty air filter. She asked if I had another air filter to replace it with, but I didn’t. I had no clue that ductless mini split units had air filters! I’m so glad she took the time to look at the ductless mini split component and warn me about the air filter.
