Comfort. Energy-efficiency. Long-term savings. It’s not just about selecting the right HVAC system for your home. In order to get the most out of your heating system, you also need to have your attic insulated properly.

The attic and roof account for about 25 percent of heat loss in a home. This results in wasted heat and cooling, an overworked HVAC system, and unnecessary expenses, including higher monthly energy bills.

Here at Ventwerx, we specialize in attic insulation, allowing you to prevent heat loss in your home, extend the lifespan of your heating system, and win you substantial savings over the long term.

Our insulation services include checking for leaks which undermine the efficiency of your insulation, leak-proofing, and the removal and disposal of existing installation.
