"We hired Edge Energy to do a full house remodel (3,000 sq. ft.,two floors, kitchen, living room, dining room, family room, breakfast space, four bedrooms, two full baths and a powder room, laundry room). This is a little outside their normal scope but we really liked the company owner, Jason Dispenza and he set up a favorable pricing schedule that didn't include some of the exorbitant management fees we have seen with other contractors. They started with an energy audit which helped to determine some of the aspects of the systems upgrades we would need. We changed the room configuration on both floors, replaced major systems (water heater, HVAC,electrical, etc.) replaced windows and put in new window openings, installed support beams, replaced the roof, insulation, electrical upgrade and lighting, replaced much of the hardwood flooring, drywall, paint and added a new front entry with a new porch. It was a major job which we lived through for months with the exception of about two weeks when the drywall work was being done. Our living there caused Edge some additional work, but they were considerate of protecting what remained in the house, and making the space as livable as possible. The result is beautiful and we probably have one of the most energy efficient homes in our area of Maryland. The Edge crew was great to work with, very considerate and careful to not disrupt our life more than necessary. Mike Hogan, the project manager was very good to work with, attentive to concerns and very responsive to suggestions. During many weeks we were talking daily. Most subs were very good as well- the HVAC, roofing and drywall guys were great. Our only concerns were with the plumber who delayed the project considerably and the final cost of the project was higher than the estimate we had originally received. I would highly recommend Edge Energy for their work and their customer responsiveness. They are technically highly competent and are very good people to work with."

"Atlas home energy solutions did an outstanding job from start to finish. They were professional, knowledgeable, courteous and easy to work with. All the crew members Ben Mott (was very knowledgeable, did the home energy audit, followed up with competitive quotes, which was adjusted to accommodate my request, offered BGE rebates upfront, patient and friendly to attend my calls and answer all the questions), Zam (Crew leader who did the exhaust fan installation), Tun (Crew leader who did an outstanding job to insulate the attic and basement), David (Crew leader who did duct cleaning and Aeroseal) were phenomenal and did an outstanding job. The end result is a day and night difference before and after the work and my BGE bill last month went down by more than $100 which is a huge cost saver. The HVAC does not run that much these days and the temperature is pretty even across the 30-year townhouse. I highly recommend Atlas home energy solutions for home energy audit and improvements."

"Have a problem with cold basement and hired Home Energy Saving Solutions, LLC to do home energy audit. Energy consultant Mohammed El-Ghoul came on time and after short inspection suggested that we do need more specific HVAC audit, not whole home energy audit. Mohammed suggested a company which can do this, also made some very useful suggestions, and checked couple of things for free. We were not charged for service despite fact that Mohammed spent almost an hour at our home and provided useful advices. Very professional and honest service and I strongly recommend Home Energy Saving Solutions, LLC and especially energy consultant Mohammed El-Ghoul!"

Energy Efficiency Auditing questions, answered by experts

Thankfully, LED lights use less electricity than incandescent lights, meaning you won’t spend as much on utility bills by using these light strips. Each 5-meter LED light strip will cost about $3 per year on your energy bill.

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.

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

Energy output depends on turbine size, average wind speed at your site, and system efficiency. A 5 kW turbine in a good wind location can generate 8,000 to 12,000 kilowatt-hours per year, which may cover a large portion of an average home’s needs. Accurate output estimates require a professional wind assessment and a review of your household’s energy usage patterns.

A good SEER rating for an HVAC system is typically between 15 and 20. However, minimum requirements vary by location; HVAC systems in northern states must have at least a 14 SEER rating, while those in southern states need a minimum of 15. For the highest possible efficiency, look for units with a SEER rating of 21 or higher. It's important to remember that a SEER rating represents the maximum efficiency a unit can achieve, not the level at which it will operate at all times.
