Yarnell Security Review

Yarnell offers quality home protection and monitoring services to homeowners in Lancaster and York, Pennsylvania. While it is a small company, it makes a lot of big promises–offering peace of mind to its customers at a rate not much higher than the national security company. While the $36.95/month fee is a bit steep, the fact that Yarnell offers home automation is a very attractive feature of the company. If you happen to live in one of the two Pennsylvania cities where it operates, Yarnell Security is worth considering.


Yarnell offers both wireless and landline-based security systems, providing customers with the equipment of their choice. The Honeywell landline systems are some of the most affordable on the market, but many customer opt for wireless equipment simply because it provides them with added security. After all, if burglars cannot cut the connection to the alarm, they will be far less likely to break into homes.

The Honeywell Lynx 5100 control panel installed in the home is a user-friendly, touchscreen controlled device. It makes it easy for the motion sensor, door and window sensors, sirens, and environmental sensors to be connected. The intuitive user interface gives homeowners easy access to all of the features of their security system, ensuring that they can easily turn everything off or on as desired. Plus, the Lynx 5100 is designed with home automation in mind, so homeowners will find it a cinch to add temperature, lighting, and other automation controls to their system.

Monitoring and Services

Yarnell is Lancaster’s oldest security company, and has been in operation since 1967. It has the highest-rated security service in the city, as well as a top-notch monitoring station. While many other companies sub-contract their monitoring, Yarnell Security does all the work of monitoring their clients’ homes. They have an A+ rating with the Better Business Bureau, proving that the company places customers and quality of service first.

The burglar alarm system is designed to immediately contact Yarnell should an attempt be made to enter your home, and the company responds within the standard 35 to 45-minute response time window. Should smoke, fire, or carbon monoxide be detected, the fire department is called to dispatch emergency services immediately.

One of the things that makes Yarnell one of Lancaster’s top choices for home security is their home automation services. Special lights and thermostat controls are installed in the home, complete with Z-wave sensors that allow homeowners remote access to HVAC and lighting. You can use the app from your smartphone, tablet, or PC, log onto the Lynx 5100 control panel, and turn your thermostat or lights up, down, or off. For homeowners looking for total control over their homes, this Yarnell service is one worth considering.


The cost of installation of the basic landline system starts at $299, and the wireless system starts at $399 for installation and activation. Adding extra devices or opting for home automation raises the price of the initial purchase, but the monthly fee stays fixed at $36.95. The standard contract lasts for 5 years, but it can be negotiated down to three.
