We had the Zero Energy Team out to our house before this summer to perform a energy evaluation of our home as I just couldn't take another hot summer here in the Desert. They had a 2 man team at my home for about 3 hours to inspect the home from top to bottom. During this time it looked like they tested just about everything they could find. They were even in my attic for about 30 minutes testing the furnace and checking for several other air leakage issues. They tested our AC ducts and homes overall leakage and found several things that would make our home more efficient... And the best part, they did all this testing for only $99 (which I got back later).
After all the testing was done, they took the results back to their office and prepared a detailed report that showed how our home tested and where we could make improvements. We signed up for one of their packages which included a radiant barrier and had them perform all the work. The team was at our house for 2 days to complete all of the work and final testing to ensure us that the work was done properly.
We it's been almost 3 months now and we have now received our third bill the other day and this month we had our biggest savings yet. A 46% savings from this same time last year (and I actually think it was hotter this summer). I will admit I was a little nervous in the begging of the process, especially because Zero would not give us an solid estimate of actual savings upfront (with the whole every house is different and you house will respond differently than your neighbors bit), but in the end the savings was way more than they ever hinted to! read more
