Has Your Furnace Been Red Tagged?

A red tagged furnace is a heater that is not safe to operate. It has been “tagged” by a professional HVAC technician to indicate its current state. There are very strict requirements set out by the governing authorities in Ottawa that all HVAC technician need to adhere to. Unfortunately, there are some companies in our industry that use this to their advantage to sell overpriced equipment.



As part of our customer first approach, we offer fast and free second opinions for Ottawa consumers. This means that we will come to your house free of charge and verify the red tag. We will also provide you with a competing quote for any HVAC work needed so that you can make an informed decision about repairs, replacements, or other HVAC need.
