My husband and I were resting in the dwelling last night, and we were watching an episode of Dancing with the stars, when both of us started hearing a bizarre sound in the ceiling. It sounded pretty much like a squirrel was walking across the roof, so both of us did not pay it any mind! When our TV show was over, both of us heard the same unusual sound. It was much louder now, and it sounded as though it was coming from behind our heads. Both locations where both of us heard the sounds, were locations where our Heating and Air Conditioning ducting was held. When both of us started to hear the same bizarre noise in weird parts of our dwelling, both of us thought there was a critter trapped in our Heating and Air Conditioning ducting. We contacted the local pet exterminator, and told him about our Strange and precarious debacle. He told us to contact a Heating and Air Conditioning repair service, in order to find out if there was any repairs for the ducting. He agreed to meet us at our dwelling, and go through our Heating and Air Conditioning ducting. I was truly hoping that both of us would be wrong about the problem, but both of us were not. When the animal exterminator looked through our Heating and Air Conditioning ducting, he found a small nest of squirrels. They were inside of our Heating and Air Conditioning ducting. They had made a tiny home in the ducting, and there were several serious repairs that would need to be handled. Once the Exterminator was able to rid the nest of squirrels, my husband and I contacted the Heating and Air Conditioning company. We had close to $600 worth of Heating and Air Conditioning ducting repairs to make, because of those squirrels. Very luckily, our insurance covered all of the damages and fees.
