Is all insulation created equal?
No! Not all insulation is equal. In fact, the insulation in many North American homes today was either improperly installed, or has settled over time, or has been compromised by air leakage. In many cases, existing insulation in homes performs so poorly that the house remains uncomfortable and energy bills are far higher than they should be. The professionals at National Heating & Cooling can assess your current insulation to determine whether it is performing, and guide you towards the best new attic, wall or basement insulation to achieve your goals while working within your budget.

Do I Need my Ducts Cleaned?
Experts do not recommend duct cleaning as an effective way to improve indoor air quality. This is because the bulk of dust and other indoor air contaminants that enter your home through your duct system actually come from the crawlspace, attic and walls. Leaky ducts allow this dust to enter the duct system, where it is delivered into the buiding's living space. With Aeroseal, these leaks are eliminated, and any existing dust or debris existing within the duct system is eradicated through your HVAC system's filters. Cleaning your ducts is necessary only in a few extreme cases, such as rodent...
