There’s no unpleasant aroma or mess left behind, & the service is warrantied to last for a minimum of more than four years.
When my heating bill was a little higher every month, I knew there was a problem, then i am genuinely conscientious about having the oil furnace professionally checked, cleaned & tuned every fall. Because of this, I was suspicious that the HVAC duct was to blame for the rising heating costs! The oil furnace was really running longer & yet having a difficult time meeting demands, and certain rooms in the home were regularly cold; Since the duct system is concealed inside walls, ceilings & crawl spaces, I was unable to check it out. I hired a professional Heating & Air Conditioning dealer to supply duct testing, however he determined that approximately 30% of my heated air was escaping through leaks at the seams & small holes, & commanded duct sealing, and at 1 time, the duct sealing process was genuinely toil intensive. Technicians were required to manually locate & repair each flaw in the ducts. There is now a process that seals the ducts from the inside out. Aeroseal duct sealing works by sending pressurized air laced with adhesive polymer particles into the ducts. As this air escape through the many imperfections, the particles stick to the edges, build up & gradually seal the holes. The process takes a few hours to complete but causes no disfigure or disruption. There’s no unpleasant aroma or mess left behind, & the service is warrantied to last for a minimum of more than four years. The Heating & Air Conditioning worker then tests the duct system to ensure the results. I was amazed by the improvement in the cleanliness, aroma & comfort of my home. I was harshly ecstatic with the much lower energy bills.
