Since we were renting the lakeside house for an entire month, we did a lot of research on it.
Of course we studied the website and the pictures, but we also drove up there to see it in person! It’s a three hour drive from home, but in this case we felt it was worth the extra time.
Everything we saw and read about the house made it seem perfect… but there was one major issue that was invisible, and we didn’t realize it until it was too late. Although the central HVAC system seemed to work perfectly, the indoor air quality was dismal, and we could not figure out why! The first night we tried our best to soldier through it, but the air quality immediately took a toll on my wife. She was sneezing and coughing, so the first thing I did was to check the air filter. Much to my surprise, the air filter was almost pristine, and must have been replaced just before we arrived. So if it wasn’t the air filter then what was causing such an issue with the air in the house? Finally I decided to get out my tool box and remove one of the grates from the outside of an air vent. Inside the ductwork was completely coated with years worth of dust and dander. Although the air filter had been changed recently, it seemed that no one had ever cleaned out the air ducts since the house was first built. There might have even been some small animals living in the ductwork.
