My Rinnai combi boiler, which was installed by a different contractor, failed and was replaced under warranty by Rinnai. Due to difficulties with the original contractors that has nothing to do with Hawk, I reached out to Rinnai to recommend someone to install the replacement. Rinnai recommended Hawk Home Services to carry out the replacement installation.
Tahla from Hawk came out personally, after hours, when his crew fell behind schedule due to unforeseen circumstances and was definitely more knowledgeable regarding Rinnai-specific installation than my original contractor. They completed the replacement in just around 2 hours and pointed out several deficiencies in the original installation, which jives with what was pointed out to me by a trusted friend who is in the trades, but lives too far to help me do the work.
I would be confident in Hawk's abilities to take care of my Rinnai boiler should anything happen to it in the future.
