ADDITIONAL CONTACT-HEATHER ADDITIONAL SERVICE AREA- .LAUREL. BOWIE FAMILY OWNED & OPERATED.

"Two-person crew arrived on time Tuesday, June 28. Attempted to clear the obstruction for 15 minutes, but they failed. Crew said they would contact my home warranty company to see if my coverage allowed a replacement. Crew said they'd get back to me in 3-4 hours. Didn't happen. Tuesday afternoon and evening, no call. Wednesday, no call. Thursday, no call. Friday, I left a message in the early morning -- no return call. I called again Friday afternoon at 3:30 p.m. Dispatcher said all technicians were unavailable until NEXT Tuesday (July 5). One week with the problem unresolved is not optimal."

We are a small, organized family-owned business. We stand behind our work, and thousand of references are available in all areas of DC, MD and VA communities. We accept payments by cash, check or credit card.

"We woke up one more recently and the temperature in the house was intolerably cold. I had the thermostat set on 75, which was much higher than we even usually have it, but even when I would switch the fan from Auto to Blow, the system seemed to cut on for a couple minutes and then just die, and it was blowing cold air. I was so worried because I was afraid to call an unknown company, and the people I'd worked with in the past weren't answering because it was so early in the morning. I called AQP and they answered right away (it was before 7AM) and said they could be here in an hour. When the technician arrived, he quickly diagnosed the problem and said he would have the part replaced and the system running within a couple hours, which he did. By afternoon, our house was warm again, and the cost was extremely affordable. I will definitely hire them again!"

Ramos Plumbing & Handyman Services is family owned and operated. We are a local company located in Rockville, Maryland, and we offer our services to most of the Montgomery county and the Washington, DC Metropolitan Area. Martin Ramos is a licensed plumber with 20 years of experience who has been trained by the AU Trade School.

"Mr. Ramos was wonderful! We had a leak coming from the ceiling in the basement. We had another well-known area plumber come out first. He looked at the leak, searched the house for a bit and told us that it was not a plumbing leak and was a foundation issue. He said he would have to cut holes in ceilings all over the house to confirm but “knew” he wouldn’t find a plumbing issue. A day before the foundation company was scheduled to come and, no doubt, charge us 10s of thousands of dollars, we got a second opinion from Mr. Ramos. He found a pipe leak within an hour, repaired it, and saved us from getting unnecessary foundation work. He said he wouldn’t stop until he found that leak. He was determined and professional."

Americool Heating & Air Conditioning Services is a family owned and operated business based out of Nokesville, VA. We offer honest and dependable service for all your heating and air conditioning needs.

"I've been using Scott Yates @Americool Heating And Air Conditioning Services LLC for the better part of 10 years without complaint. Scott is not only a subject matter expert, but he is extremely responsive while providing outstanding service at a fair and reasonable price. Most importantly, Scott is trustworthy; he takes the time to explain each and every repair without trying to gouge you (or your wife) with anything unnecessary. With that said, it was a quick decision for me to have Scott replace our 20 year old existing HVAC system with a new unit this fall. I was extremely impressed with the installation and respect the fact Scott stands behind his work. I would highly recommend Americool Heating And Air Conditioning Services LLC to anyone in need of heating or cooling services.”"

FAQs for solar panel installation projects in Fort Washington, MD

Annual inspections are recommended for residential solar systems, though specific needs vary based on several factors. Newer installations in moderate climates require less frequent professional evaluation, while systems over a decade old or those in harsh environments benefit from more regular attention. Always arrange an inspection following severe weather events that might have damaged components or affected system performance.

Pre-inspection cleaning isn't necessary, as evaluating the current condition of your panels is part of the assessment process. Professional inspectors can effectively examine systems regardless of cleanliness level, as accumulation patterns often provide valuable diagnostic information. However, if panels are completely obscured by heavy debris, bird droppings, or other materials that prevent visual examination of the surface, a basic rinse might be helpful before the scheduled inspection.

A comprehensive solar inspection examines all system components, including panels, wiring, mounting hardware, and inverters. Technicians check for physical damage like cracks or delamination, evaluate electrical connections for corrosion or looseness, and assess overall system performance against expected output levels. The inspection may also verify that safety systems are functioning correctly and that the installation complies with applicable codes and standards.

While traditional manual inspections are effective for most residential systems, specialized inspection methods may provide advantages for certain installations. Factors to consider include system size, roof complexity, accessibility challenges, and safety considerations. For multi-story homes or commercial installations where roof access is difficult or potentially hazardous, alternative inspection approaches offer improved documentation and reduced risk, though potentially at a higher cost.
