Duct Cleaning Ottawa
If your ducts look dirty, you should definitely consider duct cleaning.
Your furnace, ventilation, and air conditioning system use ducts to transfer air. The ducts can become filled with dust, mold, and allergens, especially if you have done home improvement or you have just moved into your home. Your HVAC system is responsible for air circulation, and a build-up of contaminants in your ducts means the system must work harder. This extra pressure can shorten the life of your system. These pollutants not only create an unhealthy home environment but also reduce your HVAC system’s efficiency.
