Ever since moving into my new house, I have been on a mission to fix it up. The house is over a hundred years old, and has been largely neglected. The plumbing, electric, heating and cooling systems were very outdated and in terrible condition. There was no insulation in the walls and ceilings, the windows leaked air, and the pipes were corroded and clogged. It took me several years and a great deal of money to replace all of the plumbing, wiring, furnace and air conditioner. I had new windows and doors installed, and improved the level of insulation. Despite all of these upgrades, the house still suffered from hot and cold spots, unpleasant smells, and the monthly utility bills were ungodly high. I realized that I had neglected to make any improvements to the duct system. I hired an HVAC contractor to inspect the ductwork and provide recommendations. Just as I had suspected, the duct system was allowing the heated and cooled air to escape through numerous holes and leaks at the seams. This was also allowing unconditioned and polluted air into the house, and forcing the HVAC system to work much harder. Plus, the ductwork was obstructed with a buildup of contaminants, such as dust, mold, mildew, pollen, and bacteria, which was degrading indoor air quality. I was relieved that the duct system was able to be salvaged. It simply required professional sealing and cleaning to restore optimum airflow. Once these services were complete, I noticed a huge difference in the cleanliness and comfort of my home.
