Latest good review thumbs up

Kathy | Towson, Maryland | 09/12/2023

From great to good

We replaced our roof and installed solar panels at the same time. Installation was well organized and efficient. A window screen that was accidentally torn during installation was fixed within the week. We went from great to good when the electrical panel failed inspection twice. Both times an electrician was out the next morning and had it fixed in 10 minutes, but it takes at least 2 weeks to get the county inspector back out, so we had an extra 4 weeks of electric bill, and frustration. ADBuilders paid our additional electric bill.

Latest bad review thumbs down

Sara | Elkton, Maryland | 02/07/2023

Aggressive sales, Extreme Price

This company runs on high pressure sales tactics and over inflated prices. Their strategy is to corner you in your house, presenting their offer as extremely marked down (45k to 35k) with sales incentives that are available if you sign up right now. After signing their contract, I got competing bids from other companies and received quotes of 22k for the same exact KwH set up for my house with higher quality panels. A.S.S. also dodged my questions about the cost, and radio silenced me when I decided to cancel my contract within my legal window. I would not recommend this company at all. Please do your research and get a wide variety of quotes before moving forward with a solar project.

Excellent Service

Everyone that worked for this company was very helpful. They all completed their work quickly and well. I have not had any important problems. When their equipment told them that a cell was not working they immediately came and fixed it. I am so happy with the service provided by this company that I have already asked them to do some other work for me.

Great experience, beginning to end.

I had an excellent experience with American Sentry Solar. The initial estimate with Jonathan Solovey was honest and straightforward. The installation team consisting of Casey Bottiger, Matt Tennis, Matt Tobin, Kevin Dawson, and Chad Williams, was very professional and friendly. They worked well and efficiently installing my system in under 6 hours explaining what they were doing and answering any questions I had. The final system is functioning and looks great. I'm extremely pleased with my entire experience with American Sentry Solar.

Customer Service

The team that came in to do my install was very kind and worked efficiently throughout the day. There was one electrical mishap that was not caught during the install. A neutral wire was cut to a lighting circuit. I called the project manager and they came right over the next day and fixed it. I am confident that if I ever need them for anything in the future, they will be there for us.

Going solar has been easier than we had imagined!

Our experience with American Sentry Solar were surprisingly stress free! Honestly, when it comes to solar installations, I was skeptical solely due to hearing about a co-worker’s horror story about how an installation caused water leaks due to roof damage. Then there were the legal actions to hold the solar company responsible for damages. However, we are pleased to state this was by far NOT our experience. American Sentry Solar staff and technicians took care of all documentation to include completing the state grant paperwork, initiating the process for us to receive our Solar Renewable Energy Tax Credits (SERC), providing supporting documents for our HoA application, and requesting a new electrical interconnect meter from Delmarva Power. We had our consultation with a sales consultant, Jonathan, within a few weeks of scheduling the appointment. He was very polite and gave a good introduction about American Sentry Solar and the steps involved in their solar installation. The process began with a review of our electrical consumption to determine the panel configuration suitable to our situation. Next, we talked about cost, and quite surprisingly solar ownership is very doable once federal SERC tax credit and state grant funding are factored into the purchase. Completing an on-the-spot financial application was fast and easy. Even though we decided to pursue the solar installation, we were offered several days to review the provided documents about cost, materials, and the overall investment. A site inspection was performed by Gailan who explained what our installation would entail and answered all our questions. On the day of the installation, I had to work, but the solar foreman, Casey, explained what he and his team were to do, which took less than 4 hours to install 14 panels then run conduit and wiring through the attic into a junction box on the opposite outside wall from the house circuit pane. Throughout the installation they were very polite and respectfully. In fact, Casey took time to speak with me on the phone to answer any questions I had, particularly about how the panels were mounted to roof. I was surprised to hear they didn’t drill holes in the roof. Casey explained the mounting system and even provided a sample of a mounting bracket. The installation is finished and we are very pleased with the outcome. The panels blend in nicely with our roof shingles. The interesting part is we can monitor our electricity production via a phone application as well as what we are drawing in from the power company. Going solar has been easier than we had imagined!

Professional and Friendly

The company is very easy to work with. The salesperson, Brad, was very knowledgeable and able to answer all my questions before I made the decision to purchase. All of my interactions over the phone have been friendly. They even made the extra effort to make sure the subpanel in my garage was able to be used since I wanted the panels installed on the detached garage roof. The installation was done after only a few weeks from contract signing and was done very quickly and efficiently. Still waiting for BGE to do their inspection and switch the meter but I can't wait to start saving on my electric bill.

Solar Panel Installed

I am very thankful American Design and Build and especially to Adam for answering my questions, to Brad and his team for the installation of my solar panels onto my roof. I was hesitate to install solar panels until an American Design and Build representative came to my home and showed me all aspects of solar panels, the incentives, costs, installation, etc. They did any outstanding job with the installation, they were thoughtful, courtesy and told me everything they were doing. In addition, they arrived at my home right on time and I was shocked they were done so quick. Thank You again to Brad and his teams.
