Power Vac of Ottawa also offers duct sealing, balancing, and insulation remidiation. Duct sealing protects HVAC systems and saves energy by preventing costly leaks caused by temperature fluctuations, humidity, pressure imbalances, vibrations, wear, and pest infestations. This cost-effective solution improves efficiency and airflow. Duct balancing involves adjusting registers to ensure even airflow, measuring airflow and balancing internal mechanisms to ensure consistent hot or cold air in each room. Removing attic insulation can save energy and improve air quality in your home. Old or dirty insulation can cause inefficiency and high energy bills, while dirty insulation can result from pests contaminating the material. Replacing insulation is crucial for safety and energy efficiency.
