I had called John b/c of a gas smell from furnace room. It turned out that the person who replaced our HWT recently didn't properly tighten an union. Jhon came out immediately and found the problem and had his techs fix it.
John also installed a new Goodman furnace for us. It was done within the time frame he said it would be done. We had cats and dogs and John's tech's (Andrew/Landon) were responsible and made the change over very smooth.
I highly recommend services from Supreme ENERGY. We got a 10 yr labour/parts and lifetime heatexchanger warranty also on our furnace.
Could not be happier. I shopped around for prices and although it was not a cheap furnace yet the services, warranty, quality and trust is what counts.
If you live in Cochrane or surrounding area these guys are definitely worth checking out.
