I called them because our new A/C was not able to keep up in high 80s temperatures. We knew that our insulation was way out of date, but we didn’t know how far, so we had them do an energy audit. Based on the results of that audit, they recommended replacing the cellulose insulation in the attic, sealing the top plates with spray foam, replacing some baffles, extending the bathroom fan vent to the roof, and insulating the rim joists with spray foam. We had them do it, even though they weren’t the cheapest game in town. The blower door test they did afterwards showed a 41% increase in efficiency, and our A/C is now able to keep up. Great job guys!
