If you want to be comfortable indoors, there are a lot of things that can help. Correct maintenance of the heating, cooling, and ventilation systems is at the top of the list. Lack of Heating, Ventilation, and A/C maintenance always has a negative effect on indoor comfort. However, maintenance is necessary to make sure that all parts of the Heating, Ventilation, and A/C system are running smoothly. When one part doesn’t work, the whole system can run inefficiently, making the air inside less comfortable. I found this out the hard way during my first year at my current lake house. It was always my dream to live in a lake house. So, instead of buying an easy house in town, I decided to save more and buy a house by the lake. The apartment I bought came with a small lake and 10 acres of land. I had to install a new heating, ventilation, and air conditioning system to keep the space cool in the summer and warm enough in the winter. Even though we have cold winters and mild summers, these aren’t too extreme. So, an easy Heating, Ventilation, and A/C system was the best choice for my lake house. My mistake was that I didn’t take care of my heating, ventilation, and air conditioning for 2 years, which made my home less comfortable. One warm summer day, I woke up dripping with sweat because the heating, ventilation, and air conditioning system wasn’t running. I tried to turn it on and nothing happened. This led me to call the section Heating, Ventilation, & A/C business to send me a Heating, Ventilation, & A/C professional. The guy confirmed that a clogged air filter and a few other problems were caused by a lack of HVAC maintenance. He told me to make sure I call them at least twice a year to check and make sure the Heating, Ventilation, and A/C system was working well.
