"This probably the most professional service organization I've worked with in any capacity. They did a comprehensive audit and we discussed issues that could be remediated prioritized by the biggest bang for the buck and then they did the fixes we agreed upon. I always felt like I was dealing with an expert who had my best interests at heart - work that they could have done that they advised could be deferred. Ended up increasing the insulation in the attic which I'd known for years was a problem and sealing the ducts which has made a noticeable difference. I'd happily recommend Atlas to anyone who thinks they might benefit from a home energy audit and efficiency upgrades."

"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."

"Very satisfied with responsiveness, punctuality and professionalism! Danny was able to squeeze us into Blue Star's full schedule at a time that worked for us and called before the visit for clarification about the problem, and after the visit about how things went. John called before arrival to let us know about exact timing, and was very thorough in investigating the problem and then explaining the situation. After consultation, he was able to repair our system. John also discussed what to look out for in case there are problems in the future. We have had our AC unit serviced regularly by other companies, but we will never use those other companies again. Blue Star is superior in every way! Cannot recommend highly enough. Thank you, Danny and John!!"

"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!"

"They showed up on time, looked over the project, and decided they couldn't safely replace the fan since it required outside access on a steep roof. This was the correct decision. They didn't charge me for travel time. I would hire them again."

Energy Efficiency Auditing questions, answered by experts

Dryers are designed to use as little electricity as possible, but power is still required to run the motor that turns the drum and to heat an element that pumps hot air. Eco devices are available and may lead to cost savings in the long term, but you should run the figures before committing to an eco-friendly device as they are often much more expensive to purchase.

You can check your home's humidity in a few ways. A simple option is to use a hygrometer, which you can find at a hardware or big box store. Your smartphone may also have an app that can measure humidity. Modern thermostats, particularly smart thermostats, are also able to measure humidity levels.

Costs depend on the property size, audit complexity, and whether additional testing (e.g., blower door) is included.

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.

Smart home upgrades can be worth the money. Several upgrades, including smart thermostats and ceiling fans, can help reduce your energy bills. Others make life more convenient, freeing up your time to do what you love (or get more work done). And some smart home upgrades, such as entertainment systems, simply make life more enjoyable. All are worthy causes.
