I had to call the Heating, Ventilation, and A/C company last week, because all the dust and stinks from outside were coming into our home.
It was love someone had switched the fan and it was blowing in instead of out.
I right away called the Heating, Ventilation, and A/C company. I knew this shouldn’t be happening. When I told the Heating, Ventilation, and A/C company what was happening, they sent a specialist over as soon as possible. He evaluated out the ductwork and told me that the concern was with the ductwork. There was a hole that was working love a vacuum and sucking up the air and dirt from outside. He said they had to have someone come in and service the hole right away. When the Heating, Ventilation, and A/C tech came out, he had special aerosol sealant that was released into the ductwork. The sealant was flowing through the ductwork and as it escaped through the hole; it gathered there and completely sealed it, along with any other areas that were allowing air to escape. The Heating, Ventilation, and A/C serviceman told me it was weird for this to happen. Normally there would just be a lack of airflow. In our case, both of us ended up with a style of back draft. I was cheerful both of us had noticed it before there was any permanent destruction to the Heating, Ventilation, and A/C system. I couldn’t guess how suddenly both of us noticed the difference. I had a lot of cleaning to do when the Heating, Ventilation, and A/C serviceman was done with the ductwork, however the stinks were suddenly dissipating. I thanked the Heating, Ventilation, and A/C serviceman for his help and told him how glad I was that he was quick to find the hole in the ductwork.
