I am consistently looking for ways to reduce the cost of heating plus cooling. I’ve figured out that temperature control adds up to approximately fifty percent of the condo energy usage. About a year ago, I study an article that provided a bunch of energy saving recommendations. According to that article, the majority of residential HVAC duct allows up to 30% of heated plus cooled air to escape through gaps at the seams, exhausting installation plus holes. I Googled to learn the warning signs of leaky HVAC duct plus realized I was living with all of them. It said that flaws in the HVAC duct can be responsible for inconsistent temperature from one room to another. I’ve noticed that the kitchen often feels overheated while the living room is downright cold. There is one study room upstairs that is consistently too warm. Once I started paying attention, the especially long run times of the boiler plus air conditioner plus gradually changing energy costs had me distraught. Plus, there are complications with musty odors plus an excessive amount of dust circulating in the air. I then began looking for a local Heating, Ventilation and A/C supplier that offers duct sealing. Some companies give manual sealing. They need to locate each hole or crack plus physically patch it. I found a supplier that is licensed to give Aeroseal HVAC duct sealing. This innovative process targets imperfections in the HVAC duct from the inside. It takes multiple hours to complete but causes no mess, harm or odors. It is guaranteed for ten years. The Heating, Ventilation and A/C supplier first jammed off the supply plus return registers. He then supplied pressurized air into the HVAC duct. The air was carrying adhesive polymer particles. As the air leaked from holes plus gaps, those particles clung to the edges plus steadily built up to form an airtight seal. The entire service was guided by a laptop program that then verified the results.
