"If you're looking for an A-player insulation contractor, I would recommend looking elsewhere. 
The energy consultant arrived on time and was friendly.   The estimate process was somewhat of a joke.   Basically, whatever I pointed to and said I'm interested in having something done, his response was "yeah we can do that" and then quoted some #'s from his head.   Really didn't take any time to look at anything in depth.  Didn't even go in the crawlspace to really see the extent of what needed to be done.   This compares to another company that came out and did blower-door test and used infrared thermometer equipment to check for heat loss (no charge).
The energy consultant said he would follow up with a quote via email.   I received nothing and checked junk mail folders.   I emailed for follow-up on my own and was told I would be contacted by a specialist. 
Specialist called and wanted to give me the hard sell on how they really wanted to stop by when my wife would be home.   I work in high-tech sales so I understand why they want to do this.  However, it's a huge red flag to me and exposes how they conduct their business, which is not how I conduct business.

Energy Efficiency Auditing FAQs, answered by experts

Dehumidifiers typically use 300 to 700 watts of electricity per hour, whereas portable dehumidifiers use about 40 watts per hour. The exact amount of electricity your dehumidifier will generate depends on its capacity and energy efficiency. Generally, higher-capacity dehumidifiers generate more electricity than lower-capacity units, but they also usually have better energy efficiency over the long run.

Energy output depends on turbine size, average wind speed at your site, and system efficiency. A 5 kW turbine in a good wind location can generate 8,000 to 12,000 kilowatt-hours per year, which may cover a large portion of an average home’s needs. Accurate output estimates require a professional wind assessment and a review of your household’s energy usage patterns.

The three levels of home energy audits include:

  • Level 1: Review of your energy bills and home for signs of energy inefficiency and areas for improvement. The average cost range is $0.08 to $0.12 per square foot.

  • Level 2: A level 2 ASHRAE energy audit costs $0.12 and $0.35 per square foot. In-depth analysis of your energy usage and provides a report of cost-saving changes.

  • Level 3: Comprehensive analysis and detailed recommendations for ways to improve your home’s energy efficiency. A level 3 audit costs about $0.36 to $0.50 per square foot.

Homeowners may qualify for an HVAC tax credit if they install an ENERGY STAR®-certified HVAC system that exceeds the energy efficiency minimum standards:

  • Split-System AC: 16 SEER2

  • Packaged AC: 15.2 SEER2 and 11.5 EER2

  • Ducted Split Heat Pump: 15.2 SEER2, 7.8 HSPF2, and 11.7 EER2 

  • Packaged Heat Pump: 15.2 SEER2, 7.2 HSPF2, and 10.6 EER2

  • Mini-Split System: 16 SEER2, 9 HSPF2, and 12 EER2

You can claim up to 30% of the cost of the job, subject to maximums.

There are a few ways to reduce your electricity bills if you use window AC units to keep cool. Set the unit temperature at least 1 degree higher than it is currently to reduce costs. Keep the unit clean for it to run efficiently. You may want to hire a window AC specialist near you to inspect the unit once a year and keep it in tip-top shape.
