"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."

"I had a new electrical line I wanted to run for a display light attached to a grandfather clock in our foyer. I also requested a switch be added to our wall panel by the front door to operate it. The job involved seeking a route for running wire behind the ceiling and drywall from our basement to the first floor of the house. The installation was complicated and obviously required a healthy amount of expertise in all respects. The work was accomplished with a minimal amount of mess (two small holes) and the quad switch panel added by our front door operates flawlessly. During the same visit they also replaced four decorative ceiling light fixtures and repaired a bad electrical outlet to boot. The workers were fast, efficient and friendly (even to my dog). I can't say enough about this company to do this justice. Very satisfied with my decision to give them a call."

"I used this company to perform a home inspection before I bought my house. Due to its negligence and breach of contract, 9 months after I moved in, I had to replace the roof on the house. The company will do nothing to rectify the situation. They are cheats and liars that hide behind their contracts. Their inspectors take every shortcut, and they will not protect you during the home buying process. Just don’t use them."

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."

Energy Efficiency Auditing questions, answered by experts

There is no blanket figure for a residential home’s electrical load, since load varies by the size of the home, how many appliances are used, and the efficiency of their electrical systems. Typically, however, it’s safe to assume 40 to 60 amps is the average electrical load of a residential home. 

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

The difference between an energy auditor and a home inspector is primarily in the purpose of the inspection. The energy auditor conducts tests in your home to determine the energy efficiency levels in areas like windows, insulation, and doorways. The auditor then makes recommendations for ways to improve a home’s energy efficiency

A home inspector examines various structures of your home to determine that everything is up to code and gauge the condition of features like the roof, foundation, HVAC, and electrical. The home inspector reports on the overall home and makes repair recommendations.

There are several signs that your house might have poor ventilation, including lingering odors, condensation on your windows, or mold and mildew. Your home may also feel stale and stuffy, or you might have trouble maintaining a comfortable temperature in your home. On top of that, you might develop allergy symptoms, such as sneezing, coughing, or headaches.

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.
