I'm having a very hard time finding an insulation company to give me a quote for my new house. I have house plans I can send you. Please let me know where to send the plans to. If you do residential HVAC, i'd like a quote on that as well. Thanks.

I wanted an estimate on having foam insulation blown into pre-existing walls

The fireplace is a main concern as it gets extremely cold in the winter time. The crawl space under the fireplace may not be properly insulated. The space behind the microwave oven in the kitchen is also a concern for improper insulation.

We have lived in our new home (built in 1957) for about one year and have noticed very high utility bills. We would like to investigate and prioritize ways in which we could lower utility costs and increase energy efficiency.
Roxburgh Ave in Rock Hill
The builder appears to have not insulated the sill plates on our home. Because of this and poor insulation in walls (especially around windows) our heat bill is twice the average home cost for our area per Duke Electric.
Sunset Ridge Drive in Rock Hill
I would like to check how energy efficient my house is. I have one a/c unit outside and two thermostats inside the house. My downstairs is always cold and the upstairs is always hot. I would like energy assessment of my house.
