“We have worked with Randy for over 20 years and he has always provided us with responsive, reliable service. We know we can count on him to maintain the fire alarm systems in at the properties he services.”
Mary Schnoke

“Randy at Reliable designed and installed and serviced a security system at our home. That was 25 years ago and he kept it functioning through several difficult situations we encountered over those years. He just installed a system at our business. As usual, very satisfied. You can depend on him.”

“In June of 2013, I took over the duties of General Manager, Procold Refrigerated Services, located in Allentown, PA. This facility was constructed in the mid 1980’s and the security system in place were severely outdated. I consulted with Randy Longenbach to bring our company into the new century. Randy suggested installing a camera monitoring system with a DVD-R and re-programming the exit doors with new tampers. Within two weeks of signing the contract the new equipment arrived. His installation crew worked tirelessly in a very harsh, cold environment until the install was complete and operational. The installation went smoothly, without delay and was very professional. A few weeks later, I asked Randy about installing a temperature monitoring system. Randy was unfamiliar with any of these systems, but after some research he recommended a wall mounted system linked to the security system. Once again the installation went smoothly without incident and the system works perfectly alerting me to any low temperature readings. I would highly recommend Reliable Security Solutions for any home or business security systems.”
Jack R. Wehr

“Reliable Security Solutions is an amazing Company. I have been with them for 5 years. They are “reliable” and a dedicated service.

We recently moved to a new home and Randy was very agile to work with us and get us set up within our budget. I highly recommend working with them and very happy with our history.”
Sean Hieter
“Your company offers the perfect mix of all the latest technologies with one-on-one personal attention to customer care. I like the fact that when I call with a service issue I can talk to someone who’s personally familiar with our system and installation particulars rather than trying to explain the situation to someone I’ve never met.”

Janet Schnabel

Along with great customer service, I know I can count on Reliable Security Solutions for the best service at the best price!”

“Once again, I would like to thank you for the fine installation you have done for my client. As I have said before, because of your attention to detail and your overall customer service, I recommend you to all of our clients requiring either a system update or a new system. Again, thank you for another job well done.”

Gene T. DiPalma

“Reliable Security Solutions has provided excellent customer service with a hands-on knowledge of our security system for over 20 years.

It’s comforting to have the person who installed and understands our security system answer the phone when there’s a need for information.

As a local businessman, Randy cares about his customers’ security systems and understands the technology that keeps each one running at a reasonable price.”
Jean Mishkin
