I heat plus cool my beach house with a forced air setup which relies on air ducts. About six weeks ago, I read an article that said the average home loses 25% of heating plus cooling energy through inefficient duct systems. Since I was unhappy with the cost of my biweekly utility costs, I hired a local heating plus air conditioning contractor to perform a duct seal test. The serviceman introduced pressurized air into the duct idea plus then measured airflow at odd locations within the system. From this process, he was able to determine flow rates, the amount of leakage, plus location of the leaks. The serviceman then gave a detailed report which advised on duct sealing. I expected a lengthy, messy plus upscale project which would honestly require cutting into walls. Instead, the task was completed in a few hours, with no disruption to my home at all. The serviceman sealed off all vents plus registers, plus once again sent pressurized air into the duct system. The air contained adhesive particles, plus as those particles exited through holes or cracks, they gradually built up plus created a seal. The heating plus air conditioning serviceman then diagnosed the integrity of the ducting again, verifying the success of the sealing. Now that a large portion of the heated plus cooled air is no longer escaping through leaks in the air duct, the oil furnace plus A/C more honestly achieve perfect comfort. Shorter running costs have trimmed down my bi weekly bills. Less wear plus tear on components will hopefully increase reliability plus lengthen service life. My house warms up or cools down far more hastily, plus there are no unpleasant boiling or freezing spots. I’ve noticed less moisture, dust, fumes, or any other contaminants inside the home, and thankfully the air absolutely feels fresher.
