At Luna HVAC, we know that a well-insulated attic is the secret to a high-performing heating and cooling system. In the coastal climate of Marina, CA, poor insulation allows heat to escape in the winter and humid air to seep in during the summer. Our team specializes in upgrading under-insulated attics with premium blown-in fiberglass and cellulose materials that meet modern R-value standards. By sealing air leaks and adding a robust thermal barrier, we help reduce your HVAC workload by up to 30%, extending the life of your equipment and ensuring every room in your home stays perfectly comfortable year-round.
