Recently I was looking to replace my aging hot water tank, which was doing double duty as the heating system in my condo. I had gotten recommendations about Atomic Air from my neighbours, so I gave them a try.
Mat hauled away the old tank and put in a new tankless combi boiler. The new install is super clean, and a lot of the dangling cables and sloppy elements from the old system have been removed. It's reclaimed a ton of space in my utility closet, which was basically unusable before. And of course the new system works well.
Besides that, Mat is courteous, gave me accurate estimates, and was fairly responsive (over SMS more so than email). The only downside was that scheduling was a bit tough, since Mat had to respond to some emergency calls. But it's not surprising considering this is peak season for heating breakdowns.
