When I turned on my gas furnace last fall, I ended up with what looked prefer a large cloud, as well as it came flying out of my air vents. I wasn’t sure what it all was, until I saw there were wings in the cloud. I realized I had bugs flying through my house, as well as they had hatched in my HVAC duct. I ran downstairs as well as turned off the gas furnace, as well as called first the exterminator as well as then the Heating as well as A/C supplier. I knew I had to have the bugs eliminated before I had the HVAC duct cleaned. It took several days for the exterminator to show up. He said he would need to do 2 treatments to make sure they got all of the bugs. He did 1 treatment the day he showed up, as well as he put some kind of fog into the air vents. I had to leave my condo until the fog cleared. Two weeks later, he returned as well as did the same thing again. Once again I had to leave the house for 2 days. He told me to let him believe if I saw anymore bugs after 2 weeks, however he felt it was safe to call the Heating as well as A/C supplier as well as make an appointment to have the HVAC duct cleaned. When I called the Heating as well as A/C supplier they told me it would be about a week before they could get to the house. I set up a time as well as date for when they could wash as well as sanitize the HVAC duct. They also sent an Heating as well as A/C worker to the house to wash the gas furnace as well as make sure everything was working well.
