Paul did an amazing job of getting my Nest Thermostat installed. I'd been trying to find a Nest Thermostat installer in Melbourne and no one had a clue. Paul had already extensively researched the Nest and experimented with a Honeywell. He organised to come and assess my setup and took the unit to his workshop to test different wiring configurations optimised for my Braemar heater. I'm sure he didn't charge for all the experimentation but he's now probably the most experienced Nest installer in Melbourne and I'd highly recommend calling him in.
