"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."

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."

American Home Performance LLC
American Home Performance LLC
American Home Performance offer energy efficiency solutions to homeowners throughout the Baltimore-Washington DC metro areas. We are certified contractors in BGE, PEPCO and SMECO Home Performance with Energy Star programs.
"We were very pleased with services provided by Rick Hunt/American Home Performance. The energy audit was interesting to watch. They set up a blower to pull outside air into the house and Rick showed us on an infrared measuring tool where we had greater air infiltration. He prepared a comprehensive report recommending changes to improve energy efficiency and decrease energy bills. His report laid out a menu of recommended improvements, why the change is recommended, how much it is expected to save in future energy costs if the improvement is made, and available rebates for each improvement (from SMECO utility company). Some of the changes required follow on work for additional cost (e.g., increasing attic insulation to R-49). However, some of the recommended changes were quick no-cost changes (e.g., re-laying insulation that had been displaced when we replaced light fixtures, and adding caulk to a seam in the basement where basement wall meets floor). We subsequently contracted with American Home Performance to add insulation to our attic, weatherstrip/seal around openings/penetrations between attic and living space; and correct the venting of two bathroom exhaust fans. The workers were prompt, quick, and neat."
