Blue Frost (Ottawa) has once again proven to be the most honest and reliable firm I have ever done business with in the HVAC industry. I have an 18-year old, builder installed furnace that I anticipated would need to be replaced. Mr. Popowych's quick assessment learned this was not the case, and he proceeded to resolve the issue very efficiently. Hands down, Blue Frost (Ottawa) gets the contract for my eventual furnace replacement. A great and local contractor to deal with.
