"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 questions, answered by experts

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.

There are several signs that your house might have poor ventilation, including lingering odors, condensation on your windows, or mold and mildew. Your home may also feel stale and stuffy, or you might have trouble maintaining a comfortable temperature in your home. On top of that, you might develop allergy symptoms, such as sneezing, coughing, or headaches.

R-value measures an insulation material's thermal resistance, indicating its ability to resist heat transfer. A higher R-value signifies better insulation performance because the material is more effective at slowing heat flow. The R-value depends on the type, thickness, and density of the insulation material, such as fiberglass, foam, or cellulose. Each inch of insulation typically provides an R-value between 3 and 8. There is no single universal R-value; the optimal choice depends on your climate zone. Colder climates require a much higher R-value than warmer ones to maintain energy efficiency, keep the home warm in winter and cool in summer, and manage costs.

If your AC runs constantly, it could be due to a number of things, including a faulty thermostat, incorrect temperature settings, or broken equipment. Alternatively, you might have an airflow problem (for example, blocked vents or leaky ductwork). Either way, an HVAC pro can identify the specific problem and fix it for you.

Replacing a window frame will improve your home’s energy efficiency if the old frame is cracked or damaged in a way that allows unconditioned air from the outside into your living space or if you upgrade to a more energy-efficient window frame material. Aluminum is the least energy-efficient window frame material, followed by vinyl and wood. Fiberglass and composite frames are the most energy-efficient.
