Our offices are closed on holidays, but we have an answering service that dispatches calls to our on-call techs. We always have HVAC techs, plumbers, and electricians that can help every day of the year.
Don't know for sure but the way they treat the customers makes me think that they are open 24/7. They understand that AC breaks on normal days off. Last time I had an issue they were there way before the estimated time and they called first to make sure I was there.
