"Earth-Right Mid-Atlantic ha s done two installations. The first was to install a Solar System on our home in July 2019 and the second was to insulator attics with Earth-Shield. The Solar Panel has reduced my monthly bill to $8.33 per month for the last year. The bill is for the Chesapeake Utility Tax. The system works flawlessly. The Earth-Shield was suggested by Earth Right Mid-Atlantic's salesman Corey Argentino. I has explained that we were experiencing imbalances in heating and cooling zones in the house. He suggested a product Called Earth-Shield and the too hot and too cold zones all disappeared. The house now has better and a more uniform heating and cooling result. The Heating Ventilating and AirConditioning systems do not run as frequently. Great Job."

"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."

Energy Efficiency Auditing questions, answered by experts

Attic and whole-house fans improve a home's energy efficiency and comfort. They ventilate hot air from the attic, which reduces peak cooling loads, lowers reliance on air conditioning, and decreases indoor temperatures. This improved air circulation and expedited heat exit helps lower cooling costs, balance moisture levels, and enhance overall natural airflow, contributing to the efficient operation of other home equipment.

String lights require electricity, but not an excessive amount, especially when compared to other lighting fixtures. LED rope lights, for instance, consume around one watt per foot. Running six or seven light strings simultaneously should only cost you around $10 to $15 each month. You can save even more money by remembering to turn off your lights during daylight hours. 

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.

If you have central air conditioning, it’s fine to run your AC all day if that’s what you want—as long as the AC unit is in good condition. But if your AC runs constantly when you don’t want it to, there may be a problem with your system (like the ones we’ve mentioned above). Window AC units and wall air conditioners aren’t as powerful as central AC, so you should only run those kinds of air conditioners for eight to 12 hours at a time.

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.
