Their Story

When the Rafis spotted LEAP’s rebate offer in the Arlington County newsletter, they knew it was finally the right moment for a home energy assessment. Although they had upgraded the attic insulation and added new windows to the front of their 1950s house, they still dealt with uneven temperatures in certain rooms – most notably above the garage and in the master bedroom suite.

The assessment  confirmed some of their suspicions and shed light on other problems. They knew there was poor air flow to the master bedroom, but the assessment found that the connection between the master and the main house was not tight, letting in significant air from the exterior. Since they’ve completed the weatherization, the master bedroom is particularly better.

In Their Words

“This winter, we have not needed to use our extra space heater, whereas in prior winters we used it day and night. The air flow coming through the venting is significantly stronger now, not only in the bedroom but all over the house. It is quite astonishing how much better the conditioned air reaches all parts of our home now.  We’ve been extremely pleased with our results and have recommended the process to countless people – in fact our neighbors just had an assessment done this week.” — Teresa Rafi
