I definitely recommend him to anyone who has any AC or heating needs.

I originally called the previous company he worked for (starts with M like a famous inland sea or a diet) and their soonest appointment was 3 weeks out. They're kinda rude too and I looked up their recent reviews which have been low. So I called Nshan. I told him I want to keep my 20 year old ac in good running condition and don't want any pressure to buy a new unit. Unlike the prior technician from M company who couldn't talk enough crap about my "old" ac. So I highly recommend Nshan. He started his own company and provides responsive, high quality service!
