National Home Services No Longer In Business

We purchased a home with a tankless water heater rental that had been installed by National Home Services through Enbridge. When looking into renovating and upgrading some hvac systems in our new home we discovered that the water heater had been installed with many safety code violations which could have resulted in carbon monoxide poisoning. It took a great deal of time and effort on our part to get National to agree to release us from the rental contract (that came with the house) so we could have the water heater removed. The only reason I gave them a "1" instead of a "0" is because they did eventually agree to release us from the rental contract without penalty.
