Absolutely! Insulation will help keep comfortable temperatures throughout the year while reducing energy costs by up to 30%… You might think that it is better to have too much insulation than too little, but excessive insulation may actually harm the overall performance of your home’s HVAC system. Over-insulation restricts airflow through the ducts and reduces your home’s ventilation capability. This in turn gives rise to a host of issues, such as moisture problems, and harmful mold growth.
