Testimonials

On 7/12/2025 William Lemsky had this to say:
Called Tennies concerning a rather complex 4 way dimmer switch that I was unable to replace. Tennies spent considerable time diagnosing the issue which involved a prior "remodel box". They stuck to their original cost estimate. Excellent result and very reputable. I'd use them again in a heartbeat.
