When our office schedule your service they will ask for any special instructions for entering the home on a regular basis, or what to do if you are not home. We do ask that homeowners have the ability to provide a hidden key location, lock box code, garage code, or smart lock code. We try not to use keys to prevent any misplacement of keys and allow us to send a different technician if your regular tech happens to be off or ill the day of your service.
