Johnstone Supply Rochester

That Ryan Becker review is garbage. The reason you shouldn't replace your own limit switch is because you may be just replacing a part that is the symptom, not the cause. I've seen seasoned technicians replace the same part over and over before they realize they were not looking at the whole system operation. In the case of a limit switch issue, I would be curious to know if he checked the static pressure or the gas valve input to verify proper flow of both air throughout the system, and combustible gas. Furthermore, I would check for obstructions with my camera as well as identify if the heat exchanger is damaged which could be allowing excess heat through the airway.

But yeah, it's Johnstone's fault. New York is full of do it yourself handymen. No wonder the housing market here is terrible. Ryan, if you can't afford a professional, just say so next time.

I needed a simple button style high limit switch, I called and the boy who answered says they have it yet he won't sell it to me and i need to call a professional when it is literally one of the most simple parts to swap on the consumer side of furnace repair. Last time I checked I didn't need a license to buy a thermo switch. Wouldn't it be more unsafe to keep trying to use a furnace that has a know bad part (tested with multimeter). I am extremely dissatisfied, it would be like if i called advance auto and requested a fuel filter and they told me working on my own car was too dangerous and they cant sell me the part, what a joke.

Counter always helpful, we'll stocked with what I need to do my job. Lots of tools and display area very clean and organized. Fair prices, online system very easy to use. Pickup alays a breeze.
