Inspired Electrical Solutions Inc specializes in the sales, installation and maintenance of generac automatic standby generators for your home or small business, and offers a full range of other services from home additions, to wiring, to electrical inspections and much more.

"The work is still on going but I cannot say enough about Inspired Electrical. Starting with the incredible service from the company's call screener (if that is the right term), Rosie, she put me on the schedule right away. Thomas was the first to my house. He listened intently to my description of the problem and proceeded to test the generator components, all while having B&S Technical support on the line. He diagnosed the issue as the rotor/stator had gone bad (B&S no longer manufactures the item for this model of generator). He then gave me an unofficial quote for for a direct replacement of a more modern B&S generator (direct swap) with a ten (10) year warranty. We also discussed adding my AC to the system. Later I scheduled a formal estimate with Scot. A true gentleman who explained everything step by step, to include looking for ways to get the job done and quoted me a price less than I expected as well as describing for me a future service contract for annual testing and maintenance at an extremely reasonable price. I'm waiting for the order of a new generator to be placed and then to schedule for the work to be completed. I expect this to be just as satisfactory as this review, but Inspired Electrical is my go-to for future generator and electrical issues!"

Energy Efficiency Auditing questions, answered by experts

There are a couple of ways you can save on the cost of your home energy audit. First, find out if you qualify for programs like the Department of Energy’s Weatherization Assistance Program for low-income households. Next, check with your local utility company to find out if you qualify for any local rebate programs to offset the cost of this helpful service.

A home energy audit costs about $420 on average, ranging from about $100 to $2,250 or more. Cost factors include the size of your home, the type of testing, and the thoroughness of the audit. A Level 1 walk-through inspection will cost between $150 and $200 for the auditor to point out inefficiencies in your home. On the other hand, a more thorough Level 3 audit with testing and a detailed report will cost about $900.

Typically, a local home energy auditor is responsible for performing energy audits. A home energy auditor will conduct one of three energy audits designed by the American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE) to determine the energy efficiency of your home. The auditor often provides analysis that can help guide changes and improvements to your home for better energy efficiency, giving recommendations as necessary.

Setting your AC unit to 78 degrees can, indeed, help you save energy. In fact, according to experts, every degree you turn the unit up could save you between 1% and 3% on your energy bills. That said, turning your unit off entirely while you’re out might actually be less efficient than keeping it on at a higher temperature. Why? The unit will need to work extra hard to cool the house back off again after all those hot hours. 

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.
