It was faint at first. I’d catch a whiff of something genuinely off-putting, but then it would fade. I thought there may have been something stuck in the garbage disposal. I kept breaking up lemons and putting them down the disposal thinking it would do the trick. It didn’t. I was lighting scented candles and leaving windows open, to no avail. I simply couldn’t figure out where the aroma was coming from. It was stronger in some rooms than others but it was spreading throughout the house. When I noticed the dog pawing at an air vent, the light cooked on over my head. I got on my hands and knees for a close sniff at the vents. That’s when I knew something had died in the air duct, judging from the cat’s reaction to the aroma, I figured it was a mouse, then knowing there was a dead animal in my heating and cooling ducts was a disturbing thought. I had to get the little girl removed and whatever parts of my Heating as well as Air Conditioning plan it had touched, thoroughly cleaned. Some Heating as well as Air Conditioning companies told myself and others to call animal control first to remove the mouse. I didn’t have the patience for that. I finally found an Heating as well as Air Conditioning serviceman who agreed to remove the rodent. Turns out it was an unfortunate chipmunk that caused the foul aroma the air handler had spread throughout my home. The Heating as well as Air Conditioning serviceman removed the carcass, cleaned the section of HVAC duct where the chipmunk died and changed out the filter for the oil furnace and a/c. She ran a check on the entire heating and cooling plan then suggested I consider adding an media air cleaner to help with dog dander. I decided to go for it. I only want scrub air inside my beach house from now on.
