Excellent SRP energy audit from Heat Thermography (Jason O) prior to the work recommended. Costs were very high on this, probably over normal pricing, but the work done does appear to be (and tested out to be) very good. Communication was good, though a bit disjointed at times. I would recommend getting secondary quotes from other suppliers, but don't hesitate to recommend a quote from AES, either...for any work that needs to be done. Be sure to research the work recommended and determine your own directions first!
