"The technician was very thorough in checking to see if any subflooring had been damaged by the leak, and he explained in detail what needed to be done and gave me an estimate before starting work. I was very pleased by his solving the problem quickly. I was also pleased that the company contacted me about its plans and by the technician asking me if he could come earlier than he was scheduled as he had finished another job faster than expected. I really wanted my problem fixed quickly, so I was pleased by this request."

"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

Leaving lights on raises the electric bill, but not as much as having high-wattage light bulbs. The best way to save on electric costs is to swap your light bulbs to LED or CFL bulbs that use far fewer watts. You can also use smart lights and light switches to control usage via a smartphone or voice-controlled device.

The extra insulation helps reduce energy costs by minimizing drafts and temperature exchange between indoors and outdoors.

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.

Not all homes are suited for solar panel systems. Older roofs or those in poor condition may need repairs or replacement before solar panels can be installed. Some other factors to consider are the amount of sunlight your roof receives, the roof’s orientation and pitch, and any shading from nearby trees or buildings.

To determine the right size generator for your house, you should calculate the total wattage of the appliances and devices you want to power during an outage. List all essential items, note their start-up wattages, and add them together.

Here are some typical wattage requirements for common appliances:

  • Refrigerator: 600 watts

  • Large dehumidifier: 700 watts

  • Large window air conditioner: 1,400 watts

  • Water heater: 3,000 to 4,500 watts

  • Electric furnace: 5,000 to 25,000 watts

A 7,500-watt generator might be sufficient for essentials like a refrigerator, freezer, well pump, and lighting circuits. However, for high-demand items like a water heater or furnace, a whole-home generator is a better choice. A portable generator may be enough if you only need to power a few critical items.

While home square footage can offer a rough estimate, it is not always a reliable indicator. For reference, here are some typical generator sizes based on square footage:

  • 1,000 sq ft: 6–9 kW

  • 1,500 sq ft: 7–10 kW

  • 2,000 sq ft: 10–14 kW

  • 2,500 sq ft: 12–16 kW

  • 3,000 sq ft: 16–20 kW+

For the most accurate sizing, consult a professional who can calculate your home's peak and average power consumption and recommend the optimal generator.
