Googled this number and it indicated this is a locksmith located on San Bruno Avenue in San Francisco, CA. Hmmm.....my son dropped off a friend in the area, and thinking perhaps the friend was locked out of house, they used the locksmith and maybe he was calling to confirm payment, etc. I returned the call, but was phone was answered by a robot message selling cooling, heating, and air-conditioning services. Seriously?! Locksmith offering HVAC services? Don't need 'em....don't want 'em....won't call 'em.

I am in So Cal, and would have no need of a locksmith, especially one from San Bruno. Think you hit the nail on the head when you suspected a spoofed call for solar or HVAC. Been getting bombarded with jerks trying to sell me solar panels or wanting to clean my ducts! Blocked.

Same scumbag calling me.  I had several permits from the city for HVAC work a month ago. I wonder if this is where they get their calling info.  I've been bombarded with calls since.  I think permit information is open to the public.

Yes.  In most cities permits are public record.

No caller ID info.  I didn’t answer, and the caller did not go through the prompts to bypass my call screening device.
