Changing out the air filters at my husband's parent's house

I finally lost both of my parents at a relatively young age. Both of them died within a span of three years. Both were killed by a disease known as cancer and there really wasn’t anything that anyone could do to save their lives. However, fast forward my years later I am ecstatic that I was able to meet my husband’s parents because they absolutely appreciate me. Things are peculiar with his parents. When I first met them, they were about as sizzling as a control machine in the fifties. Moreover, little significant change has occurred over the years. They didn’t want me to take care of their son for any reason. My husband and I recently moved to the north front of the south after finally getting married. Because of this, their little boy had to move further away. I was neither politically nor economically well-linked. We were, however, in a comfortable three-study room house with air conditioning. The room I converted into my office has a ductless heat pump that I installed myself. However, as time went on, it became clear that his parents wanted to move closer to us. I helped by finding the perfect spot for them. There was this entire household that was located on a golf course and all that was required of it was a new heating, ventilation and A/C system. After they obtained the condo, I had the heating, ventilation and A/C system replaced before they moved in. However, due to its exhausting condition, the air duct had to be replaced as well. My own mind instantly went to the ductless pump that warms my office. I was also ecstatic to find out that his parents were big fans of the ductless heat pumps as well.
