Insulation is material used to slow heat transfer between indoor and outdoor spaces. It reduces heating and cooling loads, improves comfort, and lowers energy use. Effectiveness is measured by R-value, with higher values providing better thermal resistance.

Why is insulation important for HVAC?
It reduces heat loss and gain, lowering energy use and improving comfort.

Higher R-values mean greater resistance to heat flow.
Adding attic insulation helps a home stay cooler in summer and warmer in winter, reducing HVAC runtime.
Check insulation levels after renovations or roof work to prevent hidden gaps.
“Check insulation levels after renovations or roof work to prevent hidden gaps.”
Poor insulation can account for a large share of heating and cooling loss.
What R-value do I need?
It depends on climate zone, attic or wall location, and local codes.
Can insulation reduce HVAC size needs?
Yes. Better insulation reduces load, allowing smaller equipment.
How often should insulation be inspected?
Every few years or after major renovations or roof work.
