"Steve and John were phenomenal.
Well, first of all, I had only bought the dryer vent cleaning/Dominion energy audit. 
Then yesterday, my heat stopped working (coldest day yet this fall :-(
When I called about the thermostat, Kenneth recognized my name and we were able to fit both calls into today's and get me back my heat!  Thanks, Kenneth.
So, when John and Steve showed up, they were all ready to go. Explained everything to me. Then they got to work. I had to leave, but they stayed in touch with me. End of the day, my former heating/cooling service appears to have been doing a very shoddy job these past 6 years, including the original set up of the new heat pump system (poor insulation, exposed wires) and the duct work.  I have great confidence in what John and Steve showed me.
I will be changing my yearly maintenance contract over to ACHAC once this year's contract with the other service expires. I'm sold on the quality of this service!

"Wonderful, it was a very quick and easy process. Brian talked us through it and in no time we had a 3KW system mounted on a frame in the garden and the invertor installed in the basement. Brian talked us through working with our power company to get the system checked and approved and we now get credits from the power company for power we provide to the grid. In addition we are set up to get Solar Renewable Energy Credits (SRECs) payments for providing clean energy. We also got a free Energy Audit which helped locate some problems areas we were able to fix. The system has basically cut our energy costs in half. I have hesitation in recommending them to anyone interested in solar energy."

"I didn't have work done, but I called to find out about getting an inspection for mold in my house based on a previous leak. I told the person that I wanted to see if they would be able to better a previous quote from another company. I was told I could pay $325 for a mold test or I could have them come out for a $95 service call for them to assess the area and that would come off the total of the estimate if I have the work done. They didn't seem very eager to help and were not overly friendly. Maybe I'm just looking for some better customer service."

Energy Efficiency Auditing questions, answered by experts

There is no blanket figure for a residential home’s electrical load, since load varies by the size of the home, how many appliances are used, and the efficiency of their electrical systems. Typically, however, it’s safe to assume 40 to 60 amps is the average electrical load of a residential home. 

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.

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.

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.

After you receive your audit and report, review the findings and determine which of the prescribed changes you want to make to improve your home’s energy efficiency. Start by contacting the type of professionals recommended by the auditor who can help you remedy the issues discovered during the audit. Prioritize the projects by urgency, importance, and budget. Then, gather estimates from several professionals, remembering to verify any necessary licensing and experience information.
