"Mohammed handled our project—sealing and insulating our attic. He was very knowledgeable about the best way to accomplish the task in an older home such as ours; and he also ensured that our project qualified for relevant energy rebates. He was professional and courteous in answering all our questions and completed the project in one day. We highly recommend HESS and Mohammed El-Goul."

"The company deserves 1000 stars l. Chris came and gave a well thorough inspection and estimate of my actic. Had my concerns and expectations, I had several other companies come and give quotes for double the price. Especially ORKIN. Orkin tried to use care tactics to sign contract without any explanation. Chris gave the quote and the crew arrived a week later as scheduled. Chris has a great work crew who were professional , caring, and did high quality work. Every step of the way, I was communicated and was filled in. I was shown before , during and after photos. And end results were UNBELIEVABLE Chris is fair and honest, he gives reasonable prices and will not take advantage of his customers."

Maryland Solar Solutions Inc is a full-service, turn-key solar integrator serving all of Maryland. We provide grid-tied solar electric (photovoltaic) systems. We design, install & monitor. We handle all necessary documentation for grants, permitting & interconnection. We partner with a licensed electrician & other solar installation professionals as the need arises. 5 year warranty, 5 year monitoring & maintenance packages offered with all systems. Financing available.

"Great! Professional, patient and they do outstanding work. Although MSSI was more expensive than the other 3 companies from whom we received quotes, the extra money was more than worth it given their willingness to walk us through the process and respond to our many questions. Although I think I'm pretty well educated, I would highly recommend that a potential solar customer work with MSSI and pay the extra money--it'll save time and frustration in the long-run. An additional perk is that this is a woman-owned, US military veteran-owned company."

Super Service Award Winner 6 Years in a Row!! Special Pricing for Angie's List Members on all Insulation jobs. Energy Audit work! Veteran Owned & Operated, Family business focused on Exterior Upgrade Packages, Energy Efficient Improvements, Siding, Roofing, Windows, Doors, Gutters, Insulation, Efficiency Auditing, Decks, Screened Porches, Additions, and more.

"Hired them to do a BGE home energy audit, and Larry Tennant performed this for the company. This included an inspection of the attic insulation which resulted in a lot of ceiling drywall essentially coming off the joists, multiple nails popping through the paint. I was really unhappy with this new problem, since what was supposed to be a $100 energy audit now led to damage that would cost several hundred dollars to repair. From Larry's point of view, the ceiling drywall likely had pre-existing problems making it vulnerable to damage from the inspection, something he had no way of knowing. After a lot of discussion, Larry contributed $500 toward the costs of fixing the ceiling, a reasonable compromise for both parties since the drywall already appeared to have pre-existing issues. Through the experience, he was professional, responsive, and was 100% committed to finding a mutually agreeable solution months after the audit was completed. Even though I would have rather never gone through the experience, I have the highest level of respect for Larry's integrity and commitment to customer satisfaction. I would gladly hire him again if we needed his services again."

"Terrible. Scam Artist. I was supposed to just get a cleaning AFTER another company came to unclog my AC pipe. Somehow after they come to clean they turn off my heat (which was never an issue) and are telling me i have $1,000 to repair it. PLEASE BEWARE. I'm filing a complaint with the BBB and possibly the courthouse. The owner says he knows for a fact his Technicians don't lie. That speaks volumes being its a lie."

Your quality of life IS our business.

"In 2017, I contracted with them via Pepco because the 2nd floor rooms were hotter than the rest of the house, costing me greater A/C expenses. I worked with them on an energy audit to the upstairs bedrooms, removal of the acoustic ceiling tile in one room, addition/improvement of insulation, sealing in kneewalls, installation of new ceiling, insulation in the basement, and a follow-up energy audit. The auditor was very prompt and friendly but the workers didn't do an good job. The contractor was flaky. The HVAC crew were sloppy. The drywall installer/carpenter did a low-grade job by using low grade wood for the knee wall doors, and he set the ceiling inappropriately for house settling (now there are cracks between ceiling and walls). The energy audit following the work showed improvement but I'll need additional solutions to get the house to a more efficient state. I shared my disappointment with them and in 2018 they refinished cracking drywall ceiling without charge and replaced the doors - still not quality. They were bought by Minnick's, with whom in 2019 I scheduled an estimate for additional HVAC solutions for the upstairs. Minnick's jerked me around, never gave a complete estimate (I had to keep asking if it included what we discussed) and the estimate was exponentially more pricey than others and they proposed a solution that wouldn't solve the problem. I wouldn't recommend them at all."

Energy Efficiency Auditing questions, answered by experts

You can determine what size generator you need by listing the various appliances it will power during an outage. Write down the start-up watt usage, and then add them all together. 

A 7,500-watt generator will run your refrigerator, freezer, well pump, and lighting circuits without a problem. However, you’ll need an extra 3,000 to 4,500 watts to run your water heater and another 5,000 to 25,000 watts to run your electric furnace. In these instances, a whole-home generator is your best bet for running your critical equipment.

Yes, pros suggest units with high EER ratings for energy savings.

The number one culprit of high energy bills is older appliances, especially fridges and freezers that are left on all the time. These two appliances tend to last a long time, which is good, but it also means that newer models are usually significantly more energy-efficient due to upgraded technology. The second most common reason for a high bill is heating and air conditioning.

The effect a gas fireplace has on your gas bill will depend on how often you use it, the size of the rooms you’re heating with it, and the BTUs of the fireplace itself, but generally speaking, it should only cost a few cents an hour to run it when it’s on. It will consume minimal energy when it’s “off” if you have a pilot light running constantly, but some modern gas fireplaces don’t require a constant pilot light.

Generator size requirements vary wildly among properties, but typical generator sizes are listed below based on home square footage:

  • 1,000 sq ft: 6–9 kW

  • 1,500 sq ft: 7–10 kW

  • 2,000 sq ft: 10–14kW

  • 2,500 sq ft: 12–16kW

  • 3,000 sq ft: 16–20kW+

Unfortunately, home square footage isn’t always a good indicator of generator size requirements. Instead, you should call in a professional to discuss which items in your home you’d like to run via your generator. They can calculate peak and average consumption for those items and then size your generator appropriately for optimal performance.
