Hi, Looking to have an energy audit done on my house, recently purchased. Your company came up on the NJ Clean Energy website as offering a free energy audit as follows: What to Expect from a Home Energy Assessment Specially trained and certified technicians will assess your home from top to bottom. The technician will take inventory, report on the current conditions in your home and will test for: Health and safety check (carbon monoxide levels, moisture, and indoor air quality problems) Overall comfort level (cold/hot spots, indoor air quality stuffiness/stale odors) Air sealing opportunities Insulation levels Heating system efficiency Cooling system/central air conditioning efficiency, if applicable Domestic hot water system efficiency My particular situation...~90 year old cinderblock construction home, gas furnace and electric central air are >15 years old. Looking to find ways to improve the energy efficiency of the house. The ductwork could probably use some help, for example. I'd like to schedule this with you. Regards, Christopher

I live in a cape with 2 bedrooms on the second floor, covered by a shed roof, house build in mid 1950, with little or no insulation. The second floors gets direct sun, hot in summer, heat loss in winter. I am interested in an estimate for insulation. The attic is not accessible from the inside, but could be with some difficulty. The shed roof covered by a rubber membrane. Thanks
