Wish I've read the reviews before I called this company. This technician Grant kept on asking more and more money for a simple call. It's no use trying to be reasonable with him, his voice would be louder than yours - that's his business tactic. Either intentionally or unintentionally he kept on making mistakes, then correcting his mistakes, and eventually charged us over $1000 for putting in a low grade thermostat and an ignitor. Totally unprofessional!
