I found 1 Solution AV after posting a local neighborhood Facebook group to help with installation…read moreof my security doorbell video cameras. The home did not have a wired electric doorbell which was required for my cameras, and Adam (owner of 1 Solution AV) was quick to reach out. I had initially asked for recommendations for electrician but appreciated that he reached out privately to explain what I would need done. Adam immediately offered to come over and look at what I would need done and provided a free estimate. His communication / response time was quick and professional. Throughout the estimate he was professional, friendly and knowledgeable. After receiving the quote, he provided his card and without pressuring whatsoever said to call if I was interested. I reached out the same day to get scheduled. He was again quick to respond and booked me within the same week. He even reached out again to help move my installation to a Sunday morning due to the weather forecast. The installation went smoothly and quickly, and he was professional throughout the entire experience. We had some hiccups with the security system equipment (no fault of his own) and he was quick to assist as I spoke to the security system customer service. I would highly recommend Adam and 1 Solution AV and will absolutely use again for any additional services as we get settled into our new home.

After soliciting quotes from a number of area alarm service providers, Mike came to look at our property personally. He arranged an alarm system tailored to our home, even talking us out of devices and alarms that other companies had told us we needed. His price was completely reasonable (if anything, we felt like we should've paid more), he was knowledgable and friendly, and he got the job done quickly for us. Really--this company has just been a dream to work with, and we highly recommend them to anyone looking for a home security system. FYI: We are located in Philadelphia, which is about 45 minutes outside of Ivyland where Mike and his team are located.
