Duct work, before and after.
According to the America Lung Association, the indoor air in an average home is 10 times more polluted than outside air. Instead of treating the root cause of the issue – their home – homeowners purchase high-efficiency filters, allergy medicine and other medications to treat symptoms rather than doing something to eliminate the cause.
Many of the upgrades ASI completed on the showcase home demonstrate how homeowners can address the problem instead of just the symptoms. It is important to seal or replace older ductwork to keep pollutants and irritants from entering our home’s from the attic, or anywhere else considered outside such as a crawlspace or basement. Doing this potentially frees us from medications and air filters later on. This is the same great work that Allbritten has done for there home energy makeover.
If the furnace is the heart of the system, ducts are the arteries. No matter how healthy the heart may be its efficiency and effectiveness are limited by the ductwork in the home.
Insulation is important as well of course. Just like our homes, we need to reduce un-controlled airflow in duct work and add the appropriate levels of insulation to keep the heat out in the summer.
Another part of HVAC we don’t always talk about is the V for ventilation. We want to control the airflow so we know we are getting enough fresh air and that it is indeed fresh!
