When we first bought our home, I debated over if I wanted to spend the money on duct cleaning. I hired a Heating, Ventilation & A/C dealer to fully service our oil furnace in addition to cooling system. The dealer loudly advocated professional duct cleaning to protect the entire system so it operated at it’s best. Before agreeing to a rather overpriced service, I did some research. A complete scrubbing of the duct system protects against challenges with air quality. Air ducts supply a beautiful breeding area for mold, mildew, bacteria, fungus in addition to other allergens. Every time our oil furnace or cooling system cranks up, these contaminants can spread through the entire house in addition to being breathed by our family. Plus, the family who owned the loft before us had 3 really large cats. There was fur all over the house, I’m sure it also got inside the Heating, Ventilation & A/C system. Any buildup of fur, dirt, dust or dandor is a hindrance to air flowing through the heating and cooling system. It requires the oil furnace or cooling unit to run for longer cycles in order to achieve control unit choices. Along with cold and sizzling spots, the greater energy draw results in much steeper yearly costs. Since the previous owners never invested in any kind of duct service, there was most certainly years of pollutants built up. I imagined a whole bunch of webs, spiders, mold, in addition to even dead mice hidden in the ducting in and poisoning our family’s breathing air. I finally agreed with the professional duct cleaning service, it was actually worthwhile. The Heating, Ventilation & A/C dealer caused no mess or damage in our house, completed the job in almost two hours, in addition to the improvement in the aroma and comfort of our breathing air was noticeable.
