"An energy audit revealed terrible problems with our home's insulation, and we decided to start with these issues before moving on to other, smaller, projects related to energy conservation.
USA Insulation insisted that we would see a change in our home the very day they put in insulation, and I will have to agree that we did see improvements.
I returned home to find 2" diameter plugged holes in the siding every 16 or so inches in 2 rows, one on each floor. We let the insulation cure/dry for a day or two before we painted the caps to match the siding color. In the end, we decided to repaint the whole house but only the main color, not the trim. I would suggest anyone with wood siding that has this type of insulation installed, consider the cost and time to paint the house because repainting just those plugs could be noticable if the house color has faded over the years. It is a very small price to pay (money and time) for the benefits we will see.
There is a slight odor as the foam cured, but it was not toxic and not displeasant. It lasted about 48 hours before we could no longer notice the smell at all, but majority of the smell vanished in less than 24 hours.
While it is too soon to discuss how well this work is saving us money, we did see 2 immediate changes:
1) It is much quieter inside the house now.
2) The upstairs is no longer a heat trap with unbearable heat in each bedroom (home has no central heating or air conditioning).
       Let me add a 3rd change now that we have experienced a few cold evenings:
3) The house is indeed warmer and retains so much heat when the radiators go on. The radiators did not have to stay on long before the house maintained a good temperature.
USA Insulatoin, as part of their energy audit, left us with several suggestions of "do-it-yourself" projects that can provide additional energy savings in addition the major savings we will see from this insulation work.

Energy Efficiency Auditing FAQs, answered by experts

Smart glass doesn’t use a lot of electricity, and you can expect a standard window to add between $1 and $2 per year to your electric bills. Smart glass is proof that energy-efficient windows work. Although your smart windows may consume a little energy to operate, they can save enough energy to offset the costs. If you’re concerned about the minimal bump to your electricity consumption, you can opt for smart tint, which doesn’t require electricity to work.

It’s not recommended to turn off your breaker box in hopes of saving electricity. Breaker boxes were not designed to constantly be switched on and off. Therefore, turning off breakers unnecessarily can cause costly damage that outnumbers any energy savings. Only flip your breakers if absolutely necessary when troubleshooting an electrical issue.

Hawaii is currently rated as the most expensive state for utilities. How much are utilities for a house in Hawaii? With electricity costs in Hawaii totaling nearly 42 cents per kilowatt-hour, residents are paying more to run their households than any other residents. Electricity costs in Hawaii are so high, mostly due to the fact that most of the electricity available to residents is produced using oil that must be shipped in from other places.

Yes, energy-efficient options such as LEDs and solar-powered lights are available. These alternatives consume less electricity, resulting in lower utility costs. They are also more environmentally friendly due to their reduced carbon footprint and longer lifespan.

Homeowners can often access federal tax credits, such as the Investment Tax Credit (ITC), which covers a percentage of installation costs. Many states and utilities offer additional rebates, grants, or performance-based incentives. These programs can significantly lower your upfront investment. Check the Database of State Incentives for Renewables and Efficiency (DSIRE) or contact your local energy office for current offers.
