"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."

"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."

Energy Efficiency Auditing questions, answered by experts

Solar water heating systems are not one-size-fits-all. You'll likely work with a team of experts to get the job done—including solar panel installers, plumbers, and water heater installers. A specialist will help you decide if a passive or active system is best for your local weather, home layout, roof stability, and your budget.

The three levels of home energy audits include:

  • Level 1: Review of your energy bills and home for signs of energy inefficiency and areas for improvement. The average cost range is $0.08 to $0.12 per square foot.

  • Level 2: A level 2 ASHRAE energy audit costs $0.12 and $0.35 per square foot. In-depth analysis of your energy usage and provides a report of cost-saving changes.

  • Level 3: Comprehensive analysis and detailed recommendations for ways to improve your home’s energy efficiency. A level 3 audit costs about $0.36 to $0.50 per square foot.

A whole-home humidifier can impact your energy bill positively. In colder months, humidified air feels warmer, allowing you to lower your thermostat without sacrificing comfort. This can lead to energy savings as your heating system works more efficiently. However, it's crucial to use the humidifier judiciously to avoid excessive humidity, which might strain your cooling system in warmer months.

Yes, installing an attic fan can help lower your electric bill—particularly if you live in a hot and humid region. By replacing hot and stuffy air with cooler air, these fans help regulate the temperature in your attic and the rest of your home, taking some of the pressure off of your air conditioner.

DIY is possible with basic tools. Professional audits provide comprehensive assessments and tailored recommendations.
