To suit my current situation, I decided to start up a small business installing natural gas and propane fueled appliances. As a gas fitter in Ontario, I am licensed to install a wide variety of different natural gas and propane fueled appliances.In the home we install furnaces and boilers for heating, and cook tops, ovens and clothes dryers for the rest of the home. And out back we can install an natural gas BBQ, a radiant heater for the patio, or maybe a gas-fired pool or spa heater.On the commercial side, we install everything from small office or trailer heaters, to unit heaters, radiant tube heaters and commercial water heaters and boilers.
